    STATE OF CONNECTICUT v. CHRISTOPHER S.*
    (SC 20247)
    McDonald, D’Auria, Mullins, Kahn, Ecker and Vertefeuille, Js.
    Syllabus
    Pursuant to statute (§ 54-1o (b)), a ‘‘written . . . statement of a person
    under investigation for or accused of’’ certain crimes ‘‘made as a result
    of a custodial interrogation at a place of detention shall be presumed
    to be inadmissible as evidence against the person in any criminal pro-
    ceeding unless . . . [a]n electronic recording is made of the custodial
    interrogation . . . .’’
    Pursuant further to statute (§ 54-1o (h)), the presumption of inadmissibility
    under § 54-1o (b) may be overcome when the state proves, by a prepon-
    derance of the evidence, that ‘‘the statement was voluntarily given and
    is reliable, based on the totality of the circumstances.’’
    Convicted of the crimes of strangulation in the second degree and assault
    in the third degree, the defendant appealed to the Appellate Court. The
    defendant and the victim had a physical altercation in the early morning,
    and the police arrested the defendant. The arresting officer, C, read the
    defendant his rights under Miranda v. Arizona (
    384 U.S. 436
    ), both at
    the time he was arrested and later that morning at the police station.
    Thereafter, less than six hours after the defendant’s second Miranda
    warning, the defendant was questioned by a detective, M, but the interro-
    gation was not video recorded. M did not readvise the defendant of his
    Miranda rights but did confirm with the defendant that he had been
    previously advised of his rights and that he was willing to speak with
    M. M then wrote out a narrative of the incident, and the defendant, after
    making several changes, signed and initialed the statement. Before trial,
    the state filed a motion seeking permission to introduce the defendant’s
    signed statement into evidence. Although the state acknowledged that,
    because the interrogation was not recorded, the defendant’s statement
    was presumptively inadmissible pursuant to § 54-1o (b), it requested
    a hearing to establish that the defendant’s statement was admissible
    pursuant to § 54-1o (h). After the hearing, the trial court determined
    that the state could introduce the defendant’s statement, reasoning that
    the state had met its burden under § 54-1o (h) of proving that the
    defendant’s statement was voluntarily given and reliable under the total-
    ity of the circumstances. At trial, the state offered the defendant’s state-
    ment into evidence. The Appellate Court concluded, inter alia, that the
    defendant’s statement was properly admitted and affirmed the judgment
    of conviction. On the granting of certification, the defendant appealed
    to this court. Held:
    1. The defendant could not prevail on his claim that the Appellate Court
    improperly upheld the trial court’s decision to admit his unrecorded,
    written statement into evidence on the ground that the state had failed
    to meet its burden of proving, in accordance with § 54-1o (h), that
    the statement was voluntarily given and reliable under the totality of
    the circumstances:
    a. This court concluded that the defendant’s claim regarding § 54-1o (h)
    was constitutional with respect to the voluntariness inquiry but eviden-
    tiary with respect to the reliability inquiry; it was significant that the
    legislature chose to use the word ‘‘voluntar[y]’’ in a statute dealing with
    the admission of statements made by criminal defendants subject to
    custodial interrogation in places of detention because ‘‘voluntary’’ was
    a constitutional term of art in this context, and voluntary in the constitu-
    tional sense was the meaning that the statute’s intended audience of
    criminal lawyers, judges, and law enforcement personnel would assume.
    b. The defendant could not prevail on his claim that the state had failed to
    meet its burden of proving that his unrecorded statement was voluntarily
    given, as the record supported the trial court’s determination that there
    was no Miranda violation and that that defendant’s statement was volun-
    tary under the totality of the circumstances: the defendant received a
    valid Miranda warning at the police station, and there was no merit to
    the defendant’s claim that M should have readvised him of his rights
    before beginning the interrogation, as less than six hours had passed
    between the defendant’s Miranda warning at the station and the interro-
    gation, M reminded the defendant of his rights by expressly confirming
    with him that he had been advised of those rights earlier that day, the
    interview concerned the same incident for which the defendant had been
    arrested and advised of his rights, and the trial court found that the
    defendant understood the warnings he received and that he was not
    intoxicated or otherwise mentally incapacitated; moreover, the defen-
    dant, having received and understood valid Miranda warnings and volun-
    tarily participated in the interrogation, implicitly gave a knowing,
    voluntary waiver of his Miranda rights; furthermore, the totality of the
    circumstances surrounding the defendant’s interrogation supported the
    trial court’s determination that the defendant voluntarily gave his state-
    ment to M, as the defendant was thirty-eight years old and was not
    intoxicated or impaired, the interrogation lasted only one hour, there
    was no evidence that M used any potentially coercive methods during
    the interrogation, and the defendant did not explain how the specific
    circumstances, including M’s failure to record the interrogation, could
    have served to overbear his will and to elicit an involuntary confession.
    c. The defendant failed to establish that the trial court had incorrectly
    determined that his unrecorded statement was reliable because, even if
    this court were to require independent, corroborating evidence to prove
    the reliability of his statement, the totality of the circumstances in this
    case, including instances of corroboration, demonstrated that the trial
    court correctly concluded that the state had met its burden.
    2. This court declined to exercise its supervisory authority over the adminis-
    tration of justice to require trial courts to give a special instruction in
    all cases in which the police fail to record a custodial interrogation, but
    it emphasized that it was well within the trial court’s discretion to
    give a specific, cautionary instruction when the police fail to record a
    custodial interrogation in violation of § 54-1o (b); because an unrecorded
    statement obtained during a custodial interrogation already has a legisla-
    tively prescribed presumption of inadmissibility, a jury instruction in
    all cases was not necessary to guard against a threat to the integrity of
    a particular trial or the perceived fairness of the judicial system as a
    whole, and the statutes of other states that provide for a jury instruction
    requirement when the police fail to record certain custodial interroga-
    tions were distinguishable from § 54-1o because they did not provide
    for a presumption that such statements were inadmissible.

    Procedural History
    Substitute information charging the defendant with
    the crimes of burglary in the first degree, kidnapping
    in the second degree, strangulation in the second
    degree, and assault in the third degree, brought to the
    Superior Court in the judicial district of Hartford and
    tried to the jury before Bentivegna, J.; verdict and judg-
    ment of guilty of strangulation in the second degree and
    assault in the third degree, from which the defendant
    appealed to the Appellate Court, Prescott, Bright and
    Flynn, Js., which affirmed the trial court’s judgment,
    and the defendant, on the granting of certification,
    appealed to this court. Affirmed.
    Timothy H. Everett, assigned counsel, with whom,
    on the brief, were Corinne Burlingham, Brendan
    Donahue, Alexander Hyder and Michael Nunes, certi-
    fied legal interns, for the appellant (defendant).
    Matthew A. Weiner, assistant state’s attorney, with
    whom, on the brief, were Gail P. Hardy, state’s attor-
    ney, and Richard J. Rubino, senior assistant state’s
    attorney, for the appellee (state).
    Maura Barry Grinalds and Darcy McGraw filed a
    brief for the Connecticut Innocence Project et al. as
    amici curiae.
    Opinion
    McDONALD, J. General Statutes § 54-1o1 provides
    that, if a person suspected of one of several enumerated
    classes of felonies gives a statement to law enforcement
    as a result of a custodial interrogation at a detention
    facility, the statement will be presumed to be inadmissi-
    ble unless officers make an audiovisual recording of
    the interrogation. Under subsection (h) of the statute,
    the state may overcome the presumption of inadmissi-
    bility in any case by proving by a preponderance of the
    evidence that the statement ‘‘was voluntarily given and
    is reliable, based on the totality of the circumstances.’’
    General Statutes § 54-1o (h). The defendant, Christo-
    pher S., appeals from the Appellate Court’s judgment
    affirming his conviction of strangulation in the second
    degree and assault in the third degree. See State v.
    Spring, 
    186 Conn. App. 197
    , 201, 220, 
    199 A.3d 21
     (2018).
    His principal claim is that the Appellate Court incor-
    rectly upheld the trial court’s decision to admit into
    evidence a signed, written statement that he made dur-
    ing a custodial interrogation, which officers failed to
    record in violation of § 54-1o. Specifically, the defen-
    dant contends that the Appellate Court incorrectly con-
    cluded that the state had met its burden of proving that
    the statement was both voluntary and reliable under
    § 54-1o (h). The defendant also asks us to exercise our
    inherent supervisory authority to require trial courts,
    in all cases in which the police fail to record an interro-
    gation in violation of the statute, to instruct the jury
    that the police violated the law and that jurors should
    evaluate with ‘‘particular caution’’ the weight to give
    the statement and any police testimony regarding the
    interrogation. We affirm the judgment of the Appellate
    Court and decline to mandate the requested jury
    instruction.
    The Appellate Court’s opinion sets forth the facts
    that the jury reasonably could have found; see State
    v. Spring, supra, 
    186 Conn. App. 201
    –207; which we
    summarize in relevant part. The Enfield police arrested
    the defendant at approximately 5:30 a.m., after the
    defendant and the victim had a physical altercation.
    The arresting officer, Mark Critz, read the defendant
    his Miranda2 rights both at the time he was arrested
    and, again, at approximately 7:23 a.m., at the Enfield
    police station. The defendant was placed in lockup until
    approximately 1:10 p.m. the same day, when he was
    brought to the desk of Detective Martin Merritt for
    questioning. Merritt’s desk was situated in a large room
    containing a number of cubicles with walls about five
    feet high. The interrogation was not video recorded.
    Merritt did not readvise the defendant of his Miranda
    rights because Critz had informed Merritt that the defen-
    dant had previously been provided such warnings twice.
    Merritt did confirm with the defendant that he had
    been advised of his rights and was willing to speak
    with Merritt.
    Merritt asked the defendant to explain what had hap-
    pened the night before, asking clarifying questions
    when necessary and taking notes. From the defendant’s
    statements, Merritt wrote out a narrative of the incident
    on an Enfield Police Department form titled ‘‘Supple-
    ment/Statement.’’ Merritt explained to the defendant
    that this was the defendant’s statement and that it
    should reflect his perspective of what happened. The
    defendant made several changes to the statement,
    which he signed in three places and initialed in fourteen
    places. The preprinted form on which the statement was
    written also contains the following acknowledgment:
    ‘‘I HAVE READ THE ABOVE STATEMENT AND IT IS
    TRUE TO THE BEST OF MY KNOWLEDGE. I FULLY
    UNDERSTAND THAT IF I MAKE A FALSE STATE-
    MENT THAT IS UNTRUE AND WHICH IS INTENDED
    TO MISLEAD A LAW ENFORCEMENT OFFICER IN
    THE PERFORMANCE OF HIS OFFICIAL FUNCTIONS
    I WILL BE IN VIOLATION OF [GENERAL STATUTES
    § 53a-157]. A FALSE STATEMENT IS A CLASS A MIS-
    DEMEANOR, WHICH IS PUNISHABLE UP TO [ONE]
    YEAR IN JAIL AND/OR A [$1000] FINE AND NOT
    MORE THAN [THREE] YEARS PROBATION.’’ In the
    statement, the defendant also acknowledged that he
    had been advised of his rights, understood those rights,
    was making the statement of his own free will, without
    any threats or promises having been made, and that he
    was giving the statement voluntarily.
    The defendant’s statement provided the following
    summary of the incident. The defendant and the victim
    were married but had been on a break, living in separate
    residences, for about two weeks. The night before the
    incident, the defendant was watching a boxing match
    at a party. After leaving, the defendant drove to the
    victim’s house in Enfield and knocked on a porch win-
    dow. The victim let the defendant in the house, and
    they talked for a few minutes, eventually deciding to
    take a drive together. Once in the car, the defendant
    and the victim argued about having cheated on each
    other. The defendant ‘‘became very angry,’’ pulled the
    car over, and began choking the victim with his hands.
    He also ‘‘punched her once in the side of the head . . .
    and slap[ped] her several times.’’ At some point, the
    victim punched the defendant in the face and cut his
    gum, causing him to bleed from the mouth. The defen-
    dant then drove the pair to the home of the defendant’s
    ex-wife. Both the defendant and the victim had a lot of
    blood on them from the fighting. Shortly thereafter, the
    police were called. The defendant ‘‘hung out on the
    back patio for a while [and] then went for a walk,’’ and
    the police detained him while he was walking. The
    defendant talked to an officer about what had happened
    before being arrested and taken to the Enfield police
    station.
    The record reveals the following procedural history.
    The defendant was charged with one count each of (1)
    burglary in the first degree, (2) kidnapping in the second
    degree, (3) strangulation in the second degree, and (4)
    assault in the third degree. Before trial, the state, pursu-
    ant to § 54-1o, filed a motion seeking permission to
    introduce the defendant’s signed statement into evi-
    dence. In the motion, the state acknowledged that,
    because Merritt did not record the interrogation, in
    violation of § 54-1o, the defendant’s statement was pre-
    sumed inadmissible. The state requested a hearing to
    establish that the statement was admissible pursuant
    to an exception to the custodial interrogation recording
    requirement under subsections (e) and (h) of § 54-1o.
    Section 54-1o (e) (2) provides an exception to the
    recording rule if ‘‘electronic recording [is] not feasible
    . . . .’’ Even when no exception applies, § 54-1o (h)
    provides that the state may overcome the presumption
    of inadmissibility by proving, by a preponderance of
    the evidence, that the defendant’s statement ‘‘was vol-
    untarily given and is reliable, based on the totality of
    the circumstances.’’
    The court held a pretrial hearing on the state’s
    motion, at which Critz, Merritt, and Detective Sergeant
    Daniel Casale testified. Critz testified that, at approxi-
    mately 5:30 a.m., he read the defendant his Miranda
    rights from a Miranda warning card that he carries
    during his shifts, and the defendant acknowledged that
    he understood his rights. The defendant talked to Critz,
    saying that he had been at a party watching the ‘‘[Manny]
    Pacquiao’’ fight. Critz noted that the defendant was
    bleeding from the mouth, and he did not appear to
    be intoxicated. Critz also testified that he advised the
    defendant of his Miranda rights a second time at 7:23
    a.m. at the Enfield police station, using a Connecticut
    Judicial Branch form titled ‘‘Notice of Rights—Bail,’’
    which the defendant signed. Critz had no further
    involvement in the case. The state entered into evidence
    both the Miranda warning card and Notice of Rights—
    Bail form.
    Merritt testified that, at approximately 1:10 p.m., he
    spoke with the defendant at the police station in an
    interview that lasted approximately one hour. Merritt
    did not readvise the defendant of his Miranda rights
    because Critz told him that he had already given the
    defendant two advisements earlier that morning. Mer-
    ritt did testify, however, that he confirmed with the
    defendant that he had been advised of his rights and
    that the defendant spoke voluntarily. Merritt followed
    his usual technique in questioning the defendant—he
    obtained the defendant’s version of the incident and
    then wrote out a statement that the defendant could
    freely edit and adopt. The defendant made and initialed
    changes, ultimately signing the statement. Merritt also
    testified that the defendant did not appear intoxicated.
    He acknowledged that he knew that, under § 54-1o,
    he should have recorded the interrogation. Although
    Merritt testified that the police department’s recording
    equipment was not working around the time of the
    defendant’s interrogation, he also admitted that he nei-
    ther checked to find out if the equipment was working
    at the time nor documented a reason for not recording.
    Merritt also admitted that he had a department issued
    iPhone with him at the time and that holding cells at
    the station also had video cameras.
    Casale testified that he ‘‘overs[aw] the process’’ of the
    defendant’s interrogation. His office was approximately
    twenty feet from Merritt’s desk, and, during the course
    of the interview, he was ‘‘bouncing back and forth’’
    between his office and Merritt’s desk. Casale also
    acknowledged that he had no explanation for why the
    interrogation was not recorded.
    After testimony and brief argument by the parties,
    the trial court issued an oral ruling, concluding that the
    state could introduce the defendant’s statement in its
    case-in-chief. The court initially noted: ‘‘[T]he defendant
    . . . was under formal arrest. There was a postbooking
    statement. The defendant was subjected to police inter-
    rogation. This was a custodial interrogation at a police
    station. No electronic recording was made. The written
    statement [was taken from a] person under investiga-
    tion or accused of a . . . class A or B felony . . . .
    [T]he court finds by the preponderance of the evidence
    that there was [no] compliance with the electronic
    recording requirement, and . . . based on that, the
    statement is presumed to be inadmissible as evi-
    dence . . . .’’
    The court considered the claimed exceptions to § 54-
    1o that the state argued, namely, subsections (e) (2)
    and (h) of the statute. The court concluded that subsec-
    tion (e) (2) did not apply because the state had failed
    to prove that recording was not feasible. Nevertheless,
    the court determined that the state had met its burden
    under subsection (h) to prove that the statement was
    voluntarily given and reliable under the totality of the
    circumstances. The court explained the basis for its
    decision in its oral ruling on the day of the hearing and
    elucidated further in response to multiple motions for
    articulation filed by the parties during the pendency of
    the defendant’s appeal to the Appellate Court.
    As to the voluntariness inquiry, the trial court deter-
    mined that the defendant’s statement was given ‘‘pursu-
    ant to a knowing, intelligent, and voluntary waiver of
    the defendant’s Miranda rights.’’ Specifically, the court
    reasoned that the defendant had received and under-
    stood two Miranda warnings in a matter of hours before
    his interrogation, Merritt was not required to provide
    a third warning before the interrogation began, there
    was no evidence of improper or coercive interrogation
    methods by the police, there was no issue with respect
    to the defendant’s mental state, the defendant made
    edits to the statement and signed it as his own, the
    interrogation took place in an open office area and
    lasted only one hour, and the statement itself said that
    the defendant understood his rights and gave the state-
    ment voluntarily.
    As to reliability, the court concluded that the defen-
    dant’s statement was reliable based on the totality of the
    circumstances. The court credited Merritt’s testimony,
    noting that Merritt explained to the defendant that the
    written statement was intended to be ‘‘his statement
    . . . his words . . . what he believes happened . . .
    and, if there’s anything that he wants . . . to add or
    take out of the statement, then we can do so.’’ (Internal
    quotation marks omitted.) The defendant made multiple
    corrections, crossed things out, changed words, ini-
    tialed his changes, and signed each page. The court
    further reasoned that the statement was taken ‘‘pursu-
    ant to standard police practices,’’ and there was ‘‘no
    evidence of threats, promises, or coercive or deceptive
    measures by the police.’’
    The case went to trial, and the state, during its case-
    in-chief, offered the defendant’s statement into evi-
    dence. The jury ultimately found the defendant guilty
    of assault in the third degree and strangulation in the
    second degree. It found him not guilty of kidnapping
    in the second degree and burglary in the first degree.
    The defendant was sentenced to a total effective term
    of three years incarceration and two years of special
    parole.
    The defendant appealed to the Appellate Court, rais-
    ing three claims: (1) the trial court erred in granting
    the state’s motion to admit his unrecorded statement
    because the state failed to prove that the statement was
    voluntarily given and reliable; (2) the trial court abused
    its discretion by overruling the defense counsel’s objec-
    tion to an inaccurate argument made by the state; and
    (3) the Appellate Court should exercise its supervisory
    authority over the administration of justice and order
    a new trial for the defendant and require trial judges
    to give a particular jury instruction in cases in which
    the police violate § 54-1o. State v. Spring, supra, 
    186 Conn. App. 199
    –201. The Appellate Court rejected each
    of the defendant’s arguments and affirmed the judgment
    of conviction. See 
    id., 201, 220
    .
    We thereafter granted the defendant’s petition for
    certification to appeal, limited to the following issues:
    (1) ‘‘Did the Appellate Court properly uphold the trial
    court’s determination that the state met its burden of
    proving that the defendant’s statement obtained during
    a custodial interrogation, which was not recorded in
    accordance with . . . § 54-1o, was nonetheless admis-
    sible pursuant to the provisions of . . . § 54-1o (h)?’’
    And (2) ‘‘[s]hould this court exercise its supervisory
    authority over the administration of justice to require
    that, when a custodial interrogation subject to the provi-
    sions of . . . § 54-1o . . . is not recorded in accor-
    dance with that statute, a jury be instructed that it
    may consider the noncompliance with the recording
    requirement in determining the weight to accord a state-
    ment that is the product of the unrecorded custodial
    interrogation?’’ State v. Spring, 
    330 Conn. 963
    , 963–64,
    
    199 A.3d 1079
     (2019). Additional facts will be set forth
    as necessary.
    I
    We begin with the defendant’s contention that the
    Appellate Court erred by upholding the trial court’s
    decision to admit his unrecorded statement into evi-
    dence because the state failed to meet its burden of
    proving that the statement was voluntarily given and
    reliable under the totality of the circumstances, as
    required by the exception found in § 54-1o (h).
    A
    As an initial matter, the parties disagree as to whether
    the defendant’s claim regarding subsection (h) of § 54-
    1o is constitutional or evidentiary. The defendant
    argues that the legislature’s use of the word ‘‘volun-
    tar[y]’’ in § 54-1o (h) refers to the preexisting constitu-
    tional requirements that a confession may be admitted
    against a criminal defendant only if it comports with
    due process and Miranda. The defendant contends that,
    because the voluntariness inquiry has constitutional
    implications, our review of the trial court’s voluntari-
    ness determination is de novo. The state contends that
    the claim is purely evidentiary because this court has
    unequivocally stated that neither the federal nor the
    state constitution requires custodial interrogations to
    be recorded. The state thus asserts that our review is
    only for abuse of discretion, and the trial court’s finding
    that the statement was voluntarily given is ‘‘entitled
    to substantial deference . . . .’’ We conclude that the
    defendant’s claim is constitutional with respect to the
    voluntariness inquiry and evidentiary with respect to
    the reliability inquiry.
    The Appellate Court concluded that the defendant’s
    claim was not constitutional because this court has
    made clear that the recording of custodial interroga-
    tions is not a constitutional concern. State v. Spring,
    supra, 
    186 Conn. App. 208
    ; see, e.g., State v. Edwards,
    
    299 Conn. 419
    , 443–44, 
    11 A.3d 116
     (2011); State v.
    Lockhart, 
    298 Conn. 537
    , 542–44, 550 and n.6, 
    4 A.3d 1176
     (2010); State v. James, 
    237 Conn. 390
    , 428–29, 
    678 A.2d 1338
     (1996). Although we have stated that the
    constitution does not require the recording of custodial
    interrogations, we also stated in Lockhart that we were
    leaving to the legislature whether to require recording
    and how to balance competing interests to implement
    such a requirement. State v. Lockhart, supra, 574–75,
    577. Our statement that a recording is not constitution-
    ally mandated does not inform our consideration about
    whether the legislature’s chosen framework for effectu-
    ating a recording requirement might incorporate consti-
    tutional norms.
    The question of whether the legislature used the word
    ‘‘voluntar[y]’’ in § 54-1o (h) in the constitutional sense
    is a matter of statutory construction over which we
    exercise plenary review. See, e.g., Lyme Land Conser-
    vation Trust, Inc. v. Platner, 
    334 Conn. 279
    , 288, 
    221 A.3d 788
     (2019). ‘‘When construing a statute, [o]ur fun-
    damental objective is to ascertain and give effect to the
    apparent intent of the legislature. . . . In other words,
    we seek to determine, in a reasoned manner, the mean-
    ing of the statutory language as applied to the facts of
    [the] case . . . . [General Statutes] § 1-2z directs us
    first to consider the text of the statute itself and its
    relationship to other statutes. If, after examining such
    text and considering such relationship, the meaning of
    such text is plain and unambiguous and does not yield
    absurd or unworkable results, extratextual evidence of
    the meaning of the statute shall not be considered. . . .
    When a statute is not plain and unambiguous, we also
    look for interpretive guidance to the legislative history
    and circumstances surrounding its enactment, [includ-
    ing] the legislative policy it was designed to implement
    . . . .’’ (Internal quotation marks omitted.) Id., 288–89.
    Section 54-1o (b) provides: ‘‘An oral, written or sign
    language statement of a person under investigation for
    or accused of a capital felony or a class A or B felony
    made as a result of a custodial interrogation at a place
    of detention shall be presumed to be inadmissible as
    evidence against the person in any criminal proceeding
    unless: (1) An electronic recording is made of the custo-
    dial interrogation, and (2) such recording is substan-
    tially accurate and not intentionally altered.’’ The
    presumption of inadmissibility may be overcome when
    the state proves, by a preponderance of the evidence,
    that ‘‘the statement was voluntarily given and is reliable,
    based on the totality of the circumstances.’’ General
    Statutes § 54-1o (h).
    It is significant that the legislature chose to use the
    word ‘‘voluntar[y]’’ in a statute dealing with the admis-
    sion of statements made by criminal defendants subject
    to custodial interrogation in places of detention because
    ‘‘voluntary’’ is a constitutional term of art in this con-
    text. In State v. Piorkowski, 
    236 Conn. 388
    , 
    672 A.2d 921
     (1996), we explained that, ‘‘[i]n the jurisprudence
    of statements made to the police by persons accused
    of crime, traditionally there are two types of ‘voluntari-
    ness’ inquiries. One, dating from before Miranda and
    emanating from principles of due process, involves
    essentially whether the defendant’s will was overborne
    by the police in eliciting the statement. See, e.g., Ari-
    zona v. Fulminante, 
    499 U.S. 279
    , 
    111 S. Ct. 1246
    , 
    113 L. Ed. 2d 302
     (1991); Colorado v. Spring, 
    479 U.S. 564
    ,
    
    107 S. Ct. 851
    , 
    93 L. Ed. 2d 954
     (1987); Schneckloth v.
    Bustamonte, 
    412 U.S. 218

    , 
    83 S. Ct. 917
    , 
    9 L. Ed. 2d 922
     (1963). The other, deriving from
    Miranda, involves essentially whether, when the police
    interrogate a suspect who is in their custody, they prop-
    erly administer the Miranda warnings to him and he
    waives the rights about which he was warned. See, e.g.,
    Powell v. Nevada, 
    511 U.S. 79
    , 
    114 S. Ct. 1280
    , 
    128 L. Ed. 2d 1
     (1994); Colorado v. Connelly, 
    479 U.S. 157

     . . . (1979). Although Miranda is not itself
    a constitutional command; Miranda v. Arizona,

    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966);
    it is nonetheless a judicially created prophylactic rule
    designed to safeguard the defendant’s fifth amendment
    right to remain silent because of the inherently coercive
    quality of custodial interrogation. Withrow v. Williams,
    
    507 U.S. 680
    , 691–92, 
    113 S. Ct. 1745
    , 
    123 L. Ed. 2d 407
    (1993) . . . .’’ (Citations omitted.) State v. Piorkowski,
    supra, 404–405. The fact that the legislature chose to
    use this word to the exclusion of any other it could
    have chosen, and the fact that the legislature chose not
    to define it, despite having defined other words in the
    statute; see General Statutes § 54-1o (a) (1) through (5);
    suggests that it intended the word to have the constitu-
    tional meaning that the word carries in this context.
    See General Statutes § 1-1 (a) (‘‘[i]n the construction
    of the statutes, words and phrases shall be construed
    according to the commonly approved usage of the lan-
    guage; and technical words and phrases, and such as
    have acquired a peculiar and appropriate meaning in the
    law, shall be construed and understood accordingly’’).
    Relatedly, the statute’s intended audience is signifi-
    cant. For example, in State v. Piorkowski, supra, 
    236 Conn. 388
    , we construed the word ‘‘involuntariness’’ as
    used in a prior version of General Statutes § 54-94a,
    and we explained that the statute was ‘‘intended for
    the ears and eyes of criminal lawyers—both prosecu-
    tion and defense—and of judges, particularly appellate
    judges, who preside over criminal proceedings. That
    circumstance reinforces the conclusion that, when the
    legislature used the phrase ‘involuntariness of a state-
    ment’ . . . the legislature intended the phrase to mean
    what those lawyers and judges would most naturally
    think it means, namely, what its meaning has long been
    in the law of confessions.’’ Id., 409. The same is true
    here. Section 54-1o involves the admission of confes-
    sions made by criminal suspects during custodial inter-
    rogations at places of detention. It is self-evident that
    it falls squarely within the purview of criminal lawyers,
    judges, and law enforcement. In choosing the word
    ‘‘voluntar[y],’’ the legislature logically would have
    ascribed to it the meaning that its intended audience
    would assume—voluntary in the constitutional sense.
    In view of the foregoing, we agree with the defendant
    that, in passing § 54-1o and including subsection (h),
    the legislature created a new procedure that references
    and involves an existing constitutional requirement. As
    the defendant notes, § 54-1o (h) makes it ‘‘procedurally
    necessary for the state to raise the voluntariness issue
    and then to meet its traditional burden in order to over-
    come the statutory presumption of inadmissibility appli-
    cable to a statement obtained in violation of the statute’s
    recording requirement.’’ In practical effect, in cases in
    which subsection (h) applies—because the police failed
    to record and there is no applicable exception under
    subsection (e)—a defendant need not file a motion to
    suppress to seek to exclude the defendant’s statement
    from evidence. Rather, the statement is presumed to
    be inadmissible, and it is incumbent on the state to
    affirmatively seek to overcome the presumption by
    proving that, despite their failure to record, officers did
    not run afoul of the constitution. A trial court’s ultimate,
    legal determination of voluntariness in this context is
    not entitled to deference.3 The legislature also added
    to the state’s traditional, constitutional burden a new
    requirement—to prove that the defendant’s statement
    is reliable based on the totality of the circumstances.
    Accordingly, we conclude that the defendant’s claim
    with respect to voluntariness is constitutional.
    As to reliability, however, the defendant’s claim is
    evidentiary.4 By requiring the state to prove that an
    unrecorded statement is reliable, the legislature sought
    to address the risk of false confessions. See State v.
    Lockhart, supra, 
    298 Conn. 589
    –95 (Palmer, J., concur-
    ring) (explaining utility of recording in ensuring both
    that confessions are voluntarily given and that defen-
    dants do not confess falsely). In State v. James, supra,
    
    237 Conn. 390
    , this court explained that, under a Con-
    necticut common-law, evidentiary rule dating back to
    the mid-eighteenth century, the admissibility of a con-
    fession turned not on whether the statement was
    coerced but whether it was true. See 
    id.,
     414–15. We
    further explained that, in Rogers v. Richmond, 
    365 U.S. 534
    , 
    81 S. Ct. 735
    , 
    5 L. Ed. 2d 760
     (1961), the United
    States Supreme Court ‘‘rejected the [common-law]
    focus on reliability in determining whether a confession
    is admissible.’’ State v. James, supra, 415. For purposes
    of the federal constitution, ‘‘in determining whether a
    confession should be excluded as involuntary, the test
    is whether the defendant’s will was overborne, which
    is to be determined with complete disregard of whether
    . . . the [accused] in fact spoke the truth.’’ (Internal
    quotation marks omitted.) Id.; see also Rogers v. Rich-
    mond, 
    supra, 544
    . Thus, the reliability of a confession
    is not a constitutional matter under the federal constitu-
    tion, and principles that govern evidentiary rulings
    apply to our review of this claim.5 Accordingly, we con-
    clude that the defendant’s claim with respect to reliabil-
    ity is evidentiary.
    B
    We turn now to the defendant’s claim that the state
    failed to meet its burden of proving that his statement
    was voluntarily given. The defendant argues that § 54-
    1o (h) imposes a burden on the state to meet both
    traditional, constitutional tests of voluntariness: (1) that
    the defendant’s statement was taken in accordance with
    the requirements of Miranda, and (2) that the police
    did not overbear the defendant’s will in violation of his
    right to due process. The defendant acknowledges that
    the trial court did consider both Miranda and due pro-
    cess voluntariness in reaching its decision but contends
    that it came to the wrong conclusion. The state con-
    tends that the statute required it to prove only that the
    defendant’s statement comported with due process and
    that, even if compliance with Miranda was required,
    the trial court correctly determined that the defendant
    knowingly and intelligently waived his rights. We need
    not decide whether the state was required to prove
    both due process voluntariness and compliance with
    Miranda because, even if we assume that the state did
    have to prove Miranda compliance, the record supports
    the trial court’s determination that there was no
    Miranda violation and that the defendant’s statement
    was voluntarily given under the totality of the circum-
    stances.
    The standard of review of a trial court’s ruling on
    voluntariness in the context of the state’s motion to
    admit a defendant’s confession under § 54-1o (h) is the
    same as when a defendant moves to suppress a state-
    ment on the ground that it was given involuntarily.
    ‘‘[T]he trial court’s findings as to the circumstances
    surrounding the defendant’s interrogation and confes-
    sion are findings of fact . . . which will not be over-
    turned unless they are clearly erroneous. . . .
    [A]lthough we give deference to the trial court concern-
    ing these subsidiary factual determinations, such defer-
    ence is not proper concerning the ultimate legal
    determination of voluntariness. . . . Consistent with
    the well established approach taken by the United
    States Supreme Court, we review the voluntariness of
    a confession independently, based on our own scrupu-
    lous examination of the record. . . . Accordingly, we
    conduct a plenary review of the record in order to
    make an independent determination of voluntariness.’’

    State v. Lawrence, 
    282 Conn. 141
    , 153–54, 
    920 A.2d 236
     (2007).
    We begin with the defendant’s claimed Miranda vio-
    lations. The defendant contends that the police failed
    to comply with Miranda in three ways. First, the defen-
    dant argues that he did not receive a valid Miranda
    warning at the police station because the rights listed
    on the Notice of Rights—Bail form that Critz read to
    him at the station are materially different from those
    constituting a proper Miranda warning. This argument
    lacks merit.
    After first being advised of his Miranda rights at the
    time of his arrest,6 the defendant was again advised of
    his rights at the police station. At the station, Critz read
    the defendant his Miranda rights from a form titled
    Notice of Rights—Bail, which provides in relevant part
    that ‘‘[a]nything you say or any statements you make
    may be used against you.’’ (Emphasis added.) The lan-
    guage the United States Supreme Court used in
    Miranda was that ‘‘anything said can and will be used
    against the individual in court.’’ (Emphasis added.)
    Miranda v. Arizona, supra, 
    384 U.S. 469
    . The Notice
    of Rights—Bail form also provides in relevant part: ‘‘You
    have the right to not say anything about this offense
    you are charged with; you may remain silent. . . .’’ The
    defendant argues that, by contrast, ‘‘[s]tandard
    Miranda warnings are direct: ‘You have the right to
    remain silent.’ ’’ The United States Supreme Court has
    made clear that Miranda warnings need not ‘‘be given
    in the exact form described in that decision. . . . [T]he
    rigidity of Miranda [does not] exten[d] to the precise
    formulation of the warnings given a criminal defendant
    . . . and . . . no talismanic incantation [is] required
    to satisfy its strictures. . . . The inquiry is simply
    whether the warnings reasonably conve[y] to [a sus-
    pect] his rights as required by Miranda.’’ (Citations
    omitted; footnote omitted; internal quotation marks
    omitted.) Duckworth v. Eagan, 
    492 U.S. 195
    , 202–203,
    
    109 S. Ct. 2875
    , 
    106 L. Ed. 2d 166
     (1989). We conclude
    that the slight differences noted by the defendant are
    immaterial for the purpose of communicating the rele-
    vant rights to criminal suspects. The language used in
    the Notice of Rights—Bail form reasonably conveys a
    suspect’s rights under Miranda.
    The second Miranda issue that the defendant raises
    is that Merritt should have readvised the defendant of
    his rights before beginning his interrogation at 1:10 p.m.
    We disagree.
    In determining whether a defendant, who received a
    Miranda warning at an earlier time, is entitled to a
    new Miranda warning before a subsequent custodial
    interrogation, courts consider a nonexclusive list of
    eight factors: ‘‘(1) the length of time that has passed
    between the initial warnings and the subsequent interro-
    gation, (2) whether the warnings and interrogation
    occurred in the same location, (3) whether the officers
    who gave the warnings were the same as those who
    conducted the subsequent interview, (4) whether the
    subsequent interview concerned the same or new
    offenses and facts, (5) the physical settings of the
    advisement and interviews, (6) whether the officer
    reminded the suspect of his rights before resuming
    questioning, (7) whether the suspect confirmed that he
    understood his rights or manifested an awareness of
    his rights, and (8) the apparent mental and emotional
    state of the suspect.’’ In re Kevin K., 
    299 Conn. 107
    ,
    123, 
    7 A.3d 898
     (2010). No factor is dispositive; it is a
    totality of the circumstances inquiry. See 
    id.,
     125–26.
    We conclude that the relevant facts and circum-
    stances support the trial court’s conclusion that Merritt
    was not required to readvise the defendant before begin-
    ning his interrogation. Less than six hours had passed
    between the defendant’s second Miranda warning and
    the interrogation. Although some courts have deter-
    mined that readvisement was necessary after a shorter
    gap; see, e.g., People v. Sanchez, 
    88 Misc. 2d 929
    , 936,
    
    391 N.Y.S.2d 513
     (N.Y. Sup. 1977); others have deter-
    mined that readvisement was unnecessary after a longer
    gap. See, e.g., In re Interest of Miah S., 
    290 Neb. 607
    ,
    614, 
    861 N.W.2d 406
     (2015) (citing cases); see also, e.g.,
    In re Kevin K., 
    supra,
     
    299 Conn. 125
    –26 (two day gap
    between warning and interrogation favored readvise-
    ment, but, in light of totality of circumstances, readvise-
    ment was unnecessary). We acknowledge that the
    officer who gave the warning was not the one who
    performed the interrogation, but we are unpersuaded
    by the defendant’s argument that Merritt needed to
    readvise the defendant to show the defendant ‘‘that he
    was prepared to honor [the defendant’s rights].’’ It is
    sufficient that Merritt reminded the defendant of his
    rights by expressly confirming with him that he had been
    advised of his rights earlier that day, and the interview
    concerned the same incident for which the defendant
    had been arrested and advised of his rights. Moreover,
    the trial court found that the defendant understood the
    warnings he received, and there is nothing in the record
    to suggest that his understanding would have disap-
    peared or dissipated between the warnings and the
    interrogation. The trial court also found that there were
    ‘‘no issues in terms of the defendant being intoxicated
    or otherwise [mentally] incapacitated . . . .’’ In light
    of the foregoing factors, we conclude that Merritt’s deci-
    sion not to readvise the defendant of his rights did not
    violate Miranda.
    The defendant’s final Miranda claim is that he never
    gave a ‘‘knowing’’ and ‘‘voluntary’’ waiver of his Miranda
    rights, without which his statement is inadmissible. We
    disagree.
    ‘‘Even [in the absence of] the accused’s invocation
    of the right to remain silent, the accused’s statement
    during a custodial interrogation is inadmissible at trial
    unless the prosecution can establish that the accused
    in fact knowingly and voluntarily waived [Miranda]
    rights when making the statement. . . . The waiver
    . . . must be voluntary in the sense that it was the
    product of a free and deliberate choice rather than
    intimidation, coercion, or deception, and made with a
    full awareness of both the nature of the right being
    abandoned and the consequences of the decision to
    abandon it.’’ (Citation omitted; internal quotation marks
    omitted.) Berghuis v. Thompkins, 
    560 U.S. 370
    , 382–83,
    
    130 S. Ct. 2250
    , 
    176 L. Ed. 2d 1098
     (2010). Despite this
    seemingly difficult task, ‘‘[t]he prosecution . . . does
    not need to show that a waiver of Miranda rights was
    express. An implicit waiver of the right to remain silent
    is sufficient to admit a suspect’s statement into evi-
    dence.’’ (Internal quotation marks omitted.) 
    Id., 384
    .
    ‘‘[When] the prosecution shows that a Miranda warning
    was given and that it was understood by the accused, an
    accused’s uncoerced statement establishes an implied
    waiver of the right to remain silent.’’ Id.; see also State
    v. Shifflett, 
    199 Conn. 718
    , 731–32, 
    508 A.2d 748
     (1986)
    (‘‘the state must demonstrate . . . (1) that the defen-
    dant understood his rights, and (2) that the defendant’s
    course of conduct indicated that he did, in fact, waive
    those rights’’ (emphasis in original; internal quotation
    marks omitted)).
    As we have explained, the defendant received two
    valid Miranda warnings from Critz, one at 5:30 a.m.
    and one at 7:23 a.m. Critz testified that, after he adminis-
    tered the first warning, the defendant ‘‘said . . . that
    he understood his rights.’’ The defendant also adopted
    the statement that Merritt wrote during the interroga-
    tion, which included the following: ‘‘When I was
    arrested earlier this date, I was advised of my rights. I
    understand those rights and give this statement volunta-
    rily.’’7 The defendant understood his rights when Merritt
    sought to interrogate him around 1:10 p.m.
    The evidence presented at the hearing also estab-
    lished that the defendant’s statements to Merritt during
    his interrogation were not coerced. Merritt testified
    that, before he began the questioning, he confirmed
    with the defendant that the defendant had ‘‘previously
    been advised of his rights’’ and was ‘‘willing to speak
    with’’ Merritt. The defendant then gave an account of
    the incident and read, made changes to, and signed
    Merritt’s written summation of what the defendant had
    said. The statement itself expressly indicates that the
    defendant was giving the statement ‘‘voluntarily.’’ There
    is nothing in the record to suggest that Merritt obtained
    the defendant’s cooperation through physical or psy-
    chological coercion, trickery, threats, promises of
    leniency, or other questionable tactics. Accordingly,
    because the defendant received and understood valid
    Miranda warnings and voluntarily participated in Mer-
    ritt’s interrogation, he implicitly gave a knowing, volun-
    tary waiver of his Miranda rights.
    In sum, even if, as the defendant contends, the state
    had to prove that the police complied with the require-
    ments of Miranda, the record supports the trial court’s
    determination that there was no Miranda violation in
    this case.
    Finally, with respect to the second traditional volun-
    tariness inquiry, the parties agree that the court must
    also look to the totality of the circumstances to deter-
    mine whether a statement was voluntarily given. The
    defendant contends that the trial court failed to con-
    sider Merritt’s conduct in its determination that the
    defendant’s statement was voluntarily given under the
    totality of the circumstances. Specifically, the defen-
    dant argues that the court disregarded that Merritt (1)
    chose not to record the interrogation, (2) chose not to
    readvise the defendant of his Miranda rights, (3) chose
    not to have the defendant sign the waiver portion of
    the form on which his statement was written, and (4)
    ignored the defendant’s ‘‘condition,’’ which involved
    having blood on his mouth and clothing. The state
    argues that, to render a confession involuntary, the
    police misconduct must cause the suspect to confess,
    and there is no causal connection between Merritt’s
    conduct and the defendant’s will being overborne. The
    state also argues that the totality of the circumstances
    supports the trial court’s determination that the defen-
    dant voluntarily gave his statement to Merritt. We agree
    with the state.

    itself . . . any use in a criminal trial of an involuntary
    confession is a denial of due process of law.’’ (Internal

     (2000). ‘‘The state has the
    burden of proving the voluntariness of the confession
    by a fair preponderance of the evidence. . . . [T]he
    test of voluntariness is whether an examination of all
    the circumstances discloses that the conduct of law
    enforcement officials was such as to overbear [the
    defendant’s] will to resist and bring about confessions
    not freely self-determined . . . . The ultimate test
    remains . . . [i]s the confession the product of an
    essentially free and unconstrained choice by its maker?
    If it is, if he has willed to confess, it may be used against
    him. If it is not, if his will has been overborne and his
    capacity for self-determination critically impaired, the
    use of his confession offends due process. . . . The
    determination, by the trial court, whether a confession
    is voluntary must be grounded upon a consideration of
    the circumstances surrounding it. . . . Factors that
    may be taken into account, upon a proper factual show-
    ing, include: the youth of the accused; his lack of educa-
    tion; his intelligence; the lack of any advice as to his
    constitutional rights; the length of detention; the
    repeated and prolonged nature of the questioning; and
    the use of physical punishment, such as the deprivation
    of food and sleep.’’ (Internal quotation marks omitted.)

    . Under the due
    process clause of the fourteenth amendment, however,
    in order for a confession to be deemed involuntary and
    thus inadmissible at trial, there must be ‘‘police conduct,
    or official coercion, causally related to the confession
    . . . .’’ (Citations omitted; internal quotation marks
    omitted.) Id., 175. In other words, there must be an
    ‘‘essential link between [the] coercive activity of the

    Here, the record supports the trial court’s determina-
    tion that the defendant voluntarily gave his statement
    to Merritt. The defendant was thirty-eight years old at
    the time of the interrogation. There was no indication
    that he was intoxicated or impaired. He was formally
    advised of his Miranda rights twice and reminded of
    them a third time just before the interrogation began,
    at which point he had been in police custody for less
    than six hours. The interrogation itself took place in
    a large room with multiple cubicles. Questioning was
    conducted by only one official, with his supervisor
    checking in periodically. The interrogation took place
    in a single session, which lasted only one hour. The
    defendant took the opportunity to read and make multi-
    ple changes to the statement as written by Merritt,
    including that the defendant was giving his statement
    ‘‘voluntarily’’ and of his ‘‘own free will with no threats
    or promises made to’’ him. There is no evidence of
    physical or psychological punishment. There is no evi-
    dence that Merritt used any potentially coercive meth-
    ods, such as threats, promises of leniency, or deception.
    Indeed, the defendant has not even argued that Merritt
    used any such tactics or that the defendant’s will was
    actually overborne.
    Even if we assume that the trial court failed to con-
    sider Merritt’s conduct as part of the totality of the
    circumstances, the defendant has not attempted to
    explain how the specific circumstances that he lists,
    either in isolation or in the aggregate, could overbear
    a suspect’s will and elicit an involuntary confession.8
    Although it is troubling that Merritt offered no satisfac-
    tory explanation as to why the interrogation was not
    recorded,9 a failure to record does not itself bear on a
    suspect’s will. Similarly, it is not clear how Merritt’s
    failure to readvise the defendant of his Miranda rights,
    which we have concluded was not required, or his
    choice not to have the defendant sign the waiver portion
    of the form on which the statement was written, which
    is irrelevant because we have concluded that the defen-
    dant implicitly waived his Miranda rights, affected the
    defendant’s will. Nothing in the record suggests that
    the defendant was seriously injured or needed medical
    attention, and there is no connection between Merritt’s
    ‘‘ignor[ing]’’ the defendant’s bloodied gum and the
    defendant’s will being overborne. Accordingly, we con-
    clude that the defendant’s statement was freely given
    and not the result of overbearing police conduct, and its
    admission into evidence did not violate the defendant’s
    right to due process. Cf. State v. Azukas, 
    278 Conn. 267
    ,
    290–91, 
    897 A.2d 554
     (2006) (confession was deemed
    voluntary when trial court found that police conduct
    was not coercive, defendant was twice advised of
    Miranda rights, detention was for few hours, and inter-
    rogation was not prolonged).
    In sum, the Appellate Court properly upheld the trial
    court’s determination that the state met its burden
    under § 54-1o (h) of proving that the defendant’s state-
    ment was voluntarily given. As we have explained,
    assuming that the state had to prove that the police
    complied with Miranda, the record demonstrates that
    it did so. Additionally, looking to the totality of the
    circumstances surrounding the defendant’s interroga-
    tion, aside from the failure to record, there is no indica-
    tion that the police engaged in any misconduct that
    overbore the defendant’s will and elicited an involun-
    tary confession.
    C
    The defendant next claims that the Appellate Court
    improperly upheld the trial court’s determination that
    the state met its burden of proving that the statement
    was reliable under the totality of the circumstances.
    Specifically, the defendant argues that, to prove reliabil-
    ity, the state must introduce independent, corroborating
    evidence that the statement itself is true, and, here, the
    state relied only on evidence regarding the circum-
    stances under which the statement was given. The state
    contends that all of the circumstances surrounding the
    giving of a statement are relevant to a reliability determi-
    nation, but there is no requirement under our law that
    there be independent, corroborating evidence of the
    contents of the statement. Furthermore, the state
    argues that it did introduce substantial, independent
    evidence corroborating the truth of the defendant’s
    statement.
    As we explained in part I A of this opinion, the reliabil-
    ity inquiry is evidentiary in nature. ‘‘The standard that
    we apply in reviewing a trial court’s evidentiary ruling
    depends on the context in which the ruling was made.
    . . . When a trial court’s determination of admissibility
    is founded on an accurate understanding of the law, it
    must stand unless there is a showing of an abuse of
    discretion. . . . When the admissibility of the chal-
    lenged testimony turns on the interpretation of an evi-
    dentiary rule, however, we are presented with a legal
    question and our review is plenary.’’ (Citations omitted;
    footnote omitted.) State v. Burney, 
    288 Conn. 548
    , 555,
    
    954 A.2d 793
     (2008).
    We begin by emphasizing the distinction between the
    voluntariness and reliability inquiries under § 54-1o (h).
    The voluntariness inquiry addresses a defendant’s con-
    stitutional right to due process and, potentially, those
    rights protected by Miranda, without regard to whether
    a confession is true. Reliability, on the other hand, is
    concerned with whether a statement is true. See State
    v. Lockhart, supra, 
    298 Conn. 589
    –90 (Palmer, J., con-
    curring) (‘‘[s]ometimes . . . the issue is not so much
    whether the confession was the product of police coer-
    cion but, rather, whether the interrogation methods
    used by the police . . . caused the suspect to admit
    to a crime that he did not commit’’). Justice Palmer
    explained in his concurrence in Lockhart that we have
    become increasingly aware that false confessions,
    despite being counterintuitive, occur with some regular-
    ity; 
    id.,
     590–91 (Palmer, J., concurring); and that ‘‘a
    recording requirement would dramatically reduce the
    number of wrongful convictions due to false confes-
    sions . . . .’’ Id., 595 (Palmer, J., concurring). The leg-
    islative history of § 54-1o reveals that the legislature
    was also concerned with false confessions when it con-
    sidered creating the recording requirement. See 54 H.R.
    Proc., Pt. 28, 2011 Sess., p. 9481, remarks of Representa-
    tive Gary Holder-Winfield (‘‘[M]ost false confessions
    stemming from an interrogation . . . come from the
    fact that there may be some intimidation, threats or
    coercion. This [b]ill seeks to put in place [an audiovi-
    sual] recording of the interrogation such that we can
    capture and see whether . . . those threats, coercions
    or intimidations happen[ed].’’).
    Although voluntariness and reliability are distinct
    inquiries, evidence that is probative of voluntariness
    may also be probative of reliability. Specifically, evi-
    dence regarding the circumstances under which a state-
    ment was given can inform both determinations. See,
    e.g., State v. Pierre, 
    277 Conn. 42
    , 61–62, 
    890 A.2d 474
    (fact that witness indicated he was giving statement
    freely, reviewed it with attorney, and signed it in eight
    places demonstrated lack of coercion, providing suffi-
    cient indicia of reliability for admission of statement

    bility of those statements), cert. denied, 
    311 Conn. 929
    ,
    
    86 A.3d 1057
     (2014). Because the same evidence can
    be used as evidence of both requirements, courts must
    be careful not to conflate the two analyses. It is entirely
    possible for a confession to be voluntary, yet false,
    or involuntary, yet true, and courts must not collapse
    voluntariness and reliability into a single inquiry. See,
    e.g., United States v. Brown, 
    617 F.3d 857
    , 860 (6th Cir.
    2010) (‘‘even voluntary ‘inculpatory confessions . . .
    are frequently unreliable’ ’’).
    With these principles in mind, we turn to the dispute
    between the parties regarding the type of evidence that
    the state was either required or permitted to use to
    prove that the defendant’s statement was reliable. Both
    parties acknowledge that independent evidence corrob-
    orating the truth of the defendant’s statement and evi-
    dence regarding the circumstances under which the
    statement was given are relevant to reliability. We agree
    with this initial point of common ground.
    This court has regularly relied on the circumstances
    under which a statement was given to determine
    whether it is reliable. See, e.g., State v. Carrion, 
    313 Conn. 823
    , 839–40, 
    100 A.3d 361
     (2014) (listing among
    factors ‘‘particularly salient’’ to determination of relia-
    bility of child witness’ prior out-of-court statement
    whether questions eliciting statement were leading or
    open and presence of authority figure during ques-
    tioning); State v. Pierre, 
    supra,
     
    277 Conn. 61
     (‘‘[w]e
    emphasize . . . that the linchpin of admissibility is
    reliability: the statement may be excluded as substan-
    tive evidence only if the trial court is persuaded, in light
    of the circumstances under which the statement was
    made, that the statement is so untrustworthy that its
    admission into evidence would subvert the fairness of
    the fact-finding process’’ (internal quotation marks
    omitted)); State v. Mukhtaar, 
    253 Conn. 280
    , 306, 
    750 A.2d 1059
     (2000) (witness’ prior inconsistent statement
    to police that otherwise meets requirements for admis-
    sibility for substantive purposes ‘‘may have been made
    under circumstances so unduly coercive or extreme as
    to grievously undermine the reliability generally inher-
    ent in such a statement, so as to render it, in effect,
    not that of the witness’’); State v. James, supra, 
    237 Conn. 414
    –15 (general approach under Connecticut
    common-law, evidentiary rule intended to protect
    defendants from convictions based on false confessions
    was to ‘‘identify certain inducements [that] made a con-
    fession unreliable,’’ such as whether it was ‘‘obtained
    as a result of a promise of a benefit or leniency or a
    threat of harm’’ (internal quotation marks omitted)).
    Evidence that independently corroborates the sub-
    stantive truth of a statement is also highly probative
    of a statement’s reliability. As the amici point out, in
    questioning suspects, the police often hold back known
    details of the crime to see if the suspects independently
    mention details that could not be fabricated. In a related
    context, this court has also approved of the use of
    independent, corroborating evidence to establish the
    trustworthiness of a defendant’s statement. See, e.g.,
    State v. Leniart, 
    333 Conn. 88
    , 114, 
    215 A.3d 1104
     (2019)
    (under ‘‘trustworthiness’’ doctrine, which grew out of
    and modified corpus delicti rule, state may generally
    rely on defendant’s statements to establish all elements
    of crime ‘‘as long as there is sufficient, independent
    evidence to establish the trustworthiness of those state-
    ments’’); State v. Hafford, supra, 
    252 Conn. 315
     (under
    old version of corpus delicti rule, confessions were
    admissible only if state ‘‘demonstrate[d] through extrin-
    sic evidence that the crime charged had been com-
    mitted’’).
    Although independent, corroborating evidence is
    highly probative of reliability, we are not persuaded
    that independent, corroborating evidence is required
    to prove reliability under § 54-1o (h). We first consider
    the plain language of the statute. The legislature chose
    to require the state to prove that an unrecorded state-
    ment is ‘‘reliable, based on the totality of the circum-
    stances.’’ General Statutes § 54-1o (h). The fact that the
    statute calls for a ‘‘totality of the circumstances’’ inquiry
    and does not include the term ‘‘corroborating evidence’’
    undermines the defendant’s argument that any particu-
    lar type of evidence—independent, corroborating or
    otherwise—is necessary to the inquiry. See, e.g., Scho-
    lastic Book Clubs, Inc. v. Commissioner of Revenue
    Services, 
    304 Conn. 204
    , 219, 
    38 A.3d 1183
     (‘‘it is a
    well settled principle of statutory construction that the
    legislature knows how to convey its intent expressly
    . . . or to use broader or limiting terms when it chooses
    to do so’’ (citation omitted)), cert. denied, 
    568 U.S. 940
    ,
    
    133 S. Ct. 425
    , 
    184 L. Ed. 2d 255
     (2012).
    In a related statute; see Connecticut Podiatric Medi-
    cal Assn. v. Health Net of Connecticut, Inc., 
    302 Conn. 464
    , 475–76, 
    28 A.3d 958
     (2011) (looking to related stat-
    utes to construe meaning of statutory term); requiring
    the trial court to make a prima facie determination of
    the ‘‘reliability’’ of a jailhouse informant’s testimony,
    the legislature set forth a number of ‘‘factors’’ that the
    court ‘‘may consider’’ in undertaking that inquiry. Gen-
    eral Statutes § 54-86p (a). These factors include ‘‘(1)
    [t]he extent to which the . . . testimony is confirmed
    by other evidence’’; ‘‘(2) [t]he specificity of the testi-
    mony’’; ‘‘(3) [t]he extent to which the testimony con-
    tains details known only by the perpetrator of the
    alleged offense’’; ‘‘(4) [t]he extent to which the details
    of the testimony could be obtained from a source other
    than the defendant’’; and ‘‘(5) [t]he circumstances under
    which the jailhouse witness initially provided informa-
    tion supporting such testimony to . . . police . . .
    including whether the jailhouse witness was responding
    to a leading question.’’ General Statutes § 54-86p (a).
    Although corroborating evidence is included in the list,
    it is only one factor that the court may consider. The
    fact that the legislature did not require corroborating
    evidence to prove reliability in that context supports
    our conclusion that it is also just one factor to consider
    under § 54-1o (h).
    We are also unpersuaded by the line of cases that the
    defendant cites for the proposition that independent,
    corroborating evidence is required to prove reliability.
    See State v. Hafford, supra, 
    252 Conn. 317
    ; State v.
    Harris, 
    215 Conn. 189
    , 194–95, 
    575 A.2d 223
     (1990);
    State v. Doucette, 
    147 Conn. 95
    , 98–106, 
    157 A.2d 487
    (1959), overruled in part by State v. Tillman, 
    152 Conn. 15
    , 
    202 A.2d 494
     (1964); State v. LaLouche, 
    116 Conn. 691
    , 694–95, 
    166 A. 252
     (1933), overruled in part by
    State v. Tillman, 
    152 Conn. 15
    , 
    202 A.2d 494
     (1964).
    These cases deal with a different doctrine—the corpus
    delicti rule and, relatedly, trustworthiness—which,
    despite dealing with the admissibility of confessions,
    address a different concern than we address in the
    cases implicated by and culminating in the legislature’s
    passage of § 54-1o.10 The defendant has not provided
    any reason for us to conclude that the legislature had
    those doctrines in mind when it required the state to
    prove reliability under the totality of the circumstances.
    Accordingly, we are not persuaded that the requirement
    in the corpus delicti and trustworthiness context, that
    the state must introduce independent, corroborating
    evidence, mandates such a requirement in the context
    of § 54-1o (h).
    Although we do not agree with the defendant that
    the statute requires the state to introduce independent,
    corroborating evidence to prove reliability, we do agree
    with the defendant and the amici that such evidence is
    preferable in view of the purpose of the statute. The
    presumption of inadmissibility under § 54-1o is
    designed to encourage the police to record custodial
    interrogations by creating a consequence for their fail-
    ure to do so. As we noted in State v. Lockhart, supra,
    
    298 Conn. 537
    , one of the benefits of recording is to
    avoid the ‘‘swearing contests’’ between law enforce-
    ment and defendants regarding what happened in the
    interrogation room. (Internal quotation marks omitted.)
    Id., 566. When officers fail to record, we return to that
    paradigm. By requiring the police to offer independent,
    corroborating evidence, we avoid the swearing contests
    because there is other evidence from which to evaluate
    the truth of a statement, beyond the competing testimo-
    nial versions of the interrogation.
    Moreover, courts evaluating unrecorded statements
    under § 54-1o must be mindful that, even if evidence
    of the circumstances in which a statement is given is
    sufficient to conclude that the statement was volunta-
    rily given, that conclusion does not necessarily compel
    the conclusion that the same evidence is sufficient to
    conclude that the statement is reliable. See State v.
    James, supra, 
    237 Conn. 424
     (This court does not ‘‘per-
    ceive . . . that involuntariness necessarily equates
    with falsity. Although coercion is reasonably thought to
    create a reason to confess falsely, whether a particular
    coerced confession is also likely to be false depends
    on many variables.’’). In the absence of independent,
    corroborating evidence of the statement’s truth, the
    state’s evidence regarding the circumstances in which
    the statement was given should be that much stronger
    for the purpose of proving reliability.
    Having rejected the defendant’s claim that indepen-
    dent, corroborating evidence is required to prove that
    a statement is reliable, we must now determine whether
    the trial court correctly concluded that the state met
    its burden of proving that the defendant’s statement
    was reliable. We conclude that the trial court correctly
    determined that the statement was admissible as evi-
    dence at the defendant’s criminal trial.
    First, contrary to the defendant’s assertion, the state
    did introduce independent evidence that corroborated
    certain important parts of the defendant’s statement.
    In particular, the defendant’s statement is consistent
    with Critz’ testimony with respect to the circumstances
    of the arrest. The defendant’s statement explains that,
    when the police arrived at the home of the defendant’s
    ex-wife, the defendant ‘‘went for a walk. When [he]
    went for a walk, the police detained [him].’’ This is
    consistent with Critz’ testimony that, while he was pro-
    cessing the scene, officers ‘‘noticed a man walking back
    toward [the police]. . . . [T]here was an exchange of
    words, [Critz was] not quite sure what it was, and [he]
    was notified by another officer . . . that it was [the
    defendant] . . . .’’ The defendant’s statement also
    explains that, before the incident with the victim, the
    defendant was ‘‘watching the fight on TV’’ and that,
    after he was detained, he ‘‘talked to an officer about
    what had happened.’’ This is consistent with Critz’ testi-
    mony confirming, on cross-examination, that the defen-
    dant had told him that ‘‘he was at some kind of party,
    watching the Pacquiao fight.’’ The defendant’s state-
    ment also explains that the victim ‘‘punched [him] once
    in the face, causing [his] gum to be cut . . . .’’ This is
    consistent with Critz’ testimony confirming, on cross-
    examination, that Critz ‘‘noticed [that the defendant]
    apparently was bleeding from his mouth.’’ Similarly, the
    defendant’s statement notes that, after his altercation
    with the victim, ‘‘[w]e both had a lot of blood on us
    from the fighting.’’ This is consistent with Critz’ testi-
    mony that the defendant had ‘‘blood on his shirt and
    . . . blood on his phone.’’ The blood on his shirt is
    also physical evidence, consistent with the defendant’s
    statement, that an altercation had taken place. Critz’
    testimony also notes that the victim was questioned at
    the scene by other officers, which further suggests the
    occurrence of a violent, domestic dispute between the
    defendant and the victim, which is what the defendant’s
    statement describes.11
    In addition to this corroborating evidence, we also
    acknowledge all of the evidence set forth in part I B of
    this opinion that was credited by the trial court regard-
    ing the circumstances under which the statement was
    given, none of which suggests that Merritt coerced the
    defendant into giving a false confession. The defendant
    was advised of his Miranda rights, the interrogation
    lasted only one hour, the defendant made several cor-
    rections to his written statement, and Merritt did not
    use any potentially coercive interrogation methods. See,
    e.g., State v. Carrion, supra, 
    313 Conn. 841
     (fact that
    child corrected interviewer on several points indicated
    reliability because child was not just giving interviewer
    what she thought interviewer wanted); State v. Mukh-
    taar, supra, 
    253 Conn. 305
     (written, signed statement
    ‘‘provide[s] significant assurance of an accurate rendi-
    tion of the statement and that the declarant realized it
    would be relied [on]’’ (internal quotation marks omit-
    ted)). Indeed, the defendant has not argued that any
    part of his statement was untrue.
    In sum, we conclude that the defendant has failed to
    establish that the trial court incorrectly determined that
    the defendant’s statement was reliable. Even if we were
    to require independent, corroborating evidence to
    prove the reliability of a statement, the totality of the
    circumstances in this case, including instances of cor-
    roboration, demonstrates that the trial court correctly
    concluded that the state met its burden. Accordingly,
    because the state successfully proved that the defen-
    dant’s statement was both voluntarily given and reliable
    under the totality of the circumstances, we conclude
    that the trial court properly ruled that the statement was
    admissible as evidence at the defendant’s criminal trial.
    II
    The defendant also claims that this court should exer-
    cise its supervisory authority over the administration
    of justice to require our trial courts to instruct juries to
    evaluate with ‘‘particular caution’’ statements obtained
    by custodial interrogation that are out of compliance
    with the recording mandate in § 54-1o (b), and should
    order that the defendant be given a new trial because
    the trial court did not give such an instruction in this
    case.12 Specifically, the defendant contends that when,
    ‘‘as here, the court and the jury have only police assur-
    ances that they conducted a fair and proper custodial
    interrogation, the trial court should instruct the jury (1)
    that the law required that the police make a recording
    of the interrogation, (2) that the jury is authorized to
    draw an adverse inference against the state for failure
    to provide the jury with the required recording, and
    (3) that the jury must weigh testimony regarding the
    interrogation and statement obtained from it with spe-
    cial caution.’’ We decline the defendant’s invitation to
    invoke our supervisory authority to require trial courts
    to give a special instruction in all cases in which the
    police fail to record a custodial interrogation. In declin-
    ing to do so, however, we emphasize that it is well within
    the trial court’s discretion to give such an instruction
    in appropriate cases.
    At the outset, we note that the defendant did not
    request a jury instruction related to Merritt’s failure
    to record the interrogation; nor did he object to the
    instructions that were given by the court, a copy of
    which he had been given in advance of the final charge
    to the jury. As the Appellate Court noted, if this claim
    were of constitutional magnitude, it likely would have
    been deemed waived under State v. Kitchens, 
    299 Conn. 447
    , 482–83, 
    10 A.3d 942
     (2011), but we have previously
    declined to apply the waiver rule to requests that we
    exercise our supervisory authority to adopt a new rule
    regarding a special jury instruction. See State v. Diaz,
    
    302 Conn. 93
    , 100 n.5, 
    25 A.3d 594
     (2011) (although
    state argued that defendant waived claim by failing to
    request special credibility instruction, claim was not
    waived because defendant was requesting adoption of
    new rule requiring trial courts to give special instruc-
    tion, and, therefore, any such claim before trial court
    would have been futile).
    Turning to the merits of the defendant’s contention,
    we are mindful that, ‘‘[a]lthough [a]ppellate courts pos-
    sess an inherent supervisory authority over the adminis-
    tration of justice . . . [that] authority . . . is not a
    form of free-floating justice, untethered to legal princi-
    ple. . . . Our supervisory powers are not a last bastion
    of hope for every untenable appeal. They are an extraor-
    dinary remedy to be invoked only when circumstances
    are such that the issue at hand, [although] not rising
    to the level of a constitutional violation, is nonetheless
    of utmost seriousness, not only for the integrity of a
    particular trial but also for the perceived fairness of
    the judicial system as a whole. . . . Constitutional,
    statutory and procedural limitations are generally ade-
    quate to protect the rights of the defendant and the
    integrity of the judicial system. Our supervisory powers
    are invoked only in the rare circumstance [when] these
    traditional protections are inadequate to ensure the fair
    and just administration of the courts.’’ (Emphasis in
    original; internal quotation marks omitted.) State v.
    Wade, 
    297 Conn. 262
    , 296, 
    998 A.2d 1114
     (2010).
    In support of his argument, the defendant contends
    that we have previously adopted jury instructions that
    require the fact finder to scrutinize certain testimony,
    such as that of complaining witnesses, accomplices,
    and informants. See, e.g., State v. Arroyo, 
    292 Conn. 558
    , 561, 
    973 A.2d 1254
     (2009), cert. denied, 
    559 U.S. 911
    , 
    130 S. Ct. 1296
    , 
    175 L. Ed. 2d 1086
     (2010); State v.
    Patterson, 
    276 Conn. 452
    , 469–70, 
    886 A.2d 777
     (2005);
    State v. Ortiz, 
    252 Conn. 533
    , 561–63, 
    747 A.2d 487
    (2000). The defendant contends that, as in those cases,
    when the police fail to record an interrogation in viola-
    tion of § 54-1o, jurors would not be aware of the meth-
    ods the state used to procure the evidence. As such,
    the defendant argues, the jury needs to be informed of
    the provenance of the evidence and to weigh its reliabil-
    ity in light of its source.
    We are not persuaded that, in all cases in which the
    police fail to record a custodial interrogation, we should
    mandate such an instruction. As we have explained,
    ‘‘[g]enerally, a [criminal] defendant is not entitled to an
    instruction singling out any of the state’s witnesses and
    highlighting his or her possible motive for testifying
    falsely.’’ (Internal quotation marks omitted.) State v.
    Baltas, 
    311 Conn. 786
    , 820, 
    91 A.3d 384
     (2014). Unlike
    the ‘‘inevitably suspect’’ testimony of an accomplice,
    complainant, or informant; State v. Patterson, supra,
    
    276 Conn. 469
    ; evidence of an unrecorded statement
    is put before the jury only after the trial court has
    determined that the statement is more likely than not
    reliable. An unrecorded statement already has a legisla-
    tively prescribed presumption of inadmissibility and is,
    therefore, substantially different from testimony of an
    accomplice, complainant, or informant. We do not
    believe that it is necessary to mandate a jury instruction
    in all cases, when the state must already overcome the
    presumption of inadmissibility. Cf. T. Sullivan & A. Vail,
    ‘‘The Consequences of Law Enforcement Officials’ Fail-
    ure To Record Custodial Interviews as Required by
    Law,’’ 
    99 J. Crim. L. & Criminology 215
    , 215, 224–26
    (2009) (authors removed presumption of inadmissibility
    of unrecorded interviews from model recording statute
    and provided instead for jury instruction). Indeed, prior
    to the enactment of § 54-1o, we declined to invoke our
    supervisory authority to address the admission of unre-
    corded confessions. See State v. Lockhart, supra, 
    298 Conn. 576
    –77. We explained that ‘‘the procedures
    already in place to prevent the admission into evidence
    of involuntary or untrustworthy confessions’’ are suffi-
    cient to protect the integrity of a trial. Id., 577. The
    enactment of § 54-1o has made those protections even
    stronger. Given the procedures already in place to pre-
    vent the admission into evidence of involuntary or
    untrustworthy confessions, we are not convinced that
    a jury instruction in all cases is necessary to guard
    against a threat to ‘‘the integrity of a particular trial
    . . . [or] the perceived fairness of the judicial system
    as a whole.’’ (Internal quotation marks omitted.) Id.
    The defendant also points to other jurisdictions that
    require special instructions when the police fail to fol-
    low laws requiring that custodial interrogations be
    recorded. For example, state recording statutes in Mich-
    igan, New York, North Carolina, and Wisconsin provide
    for a jury instruction requirement when the police fail
    to record certain custodial interrogations. See 
    Mich. Comp. Laws Serv. § 763.9
     (LexisNexis 2016) (‘‘the jury
    shall be instructed that it is the law of this state to record
    statements of an individual in custodial detention who
    is under interrogation for a major felony and that the
    jury may consider the absence of a recording in evaluat-
    ing the evidence relating to the individual’s statement’’);
    
    N.Y. Crim. Proc. Law § 60.45
     3. (d) (McKinney 2019)
    (‘‘upon request of the defendant, the court must instruct
    the jury that the people’s failure to record the defen-
    dant’s confession, admission or other statement as
    required . . . may be weighed as a factor, but not as
    the sole factor, in determining whether such confession,
    admission or other statement was voluntarily made, or
    was made at all’’); N.C. Gen. Stat. § 15A-211 (f) (3)
    (2019) (‘‘[w]hen evidence of compliance or noncompli-
    ance with the requirements of this section has been
    presented at trial, the jury shall be instructed that it
    may consider credible evidence of compliance or non-
    compliance to determine whether the defendant’s state-
    ment was voluntary and reliable’’); 
    Wis. Stat. Ann. § 972.115
     (2) (a) (West 2007) (‘‘upon a request made by
    the defendant . . . and unless the state asserts and the
    court finds that [certain conditions apply] or that good
    cause exists for not providing an instruction, the court
    shall instruct the jury that it is the policy of this state
    to make an audio or audio and visual recording of a
    custodial interrogation of a person suspected of com-
    mitting a felony and that the jury may consider the
    absence of an audio or audio and visual recording of
    the interrogation in evaluating the evidence relating to
    the interrogation and the statement in the case’’).13
    Unlike the statutory provisions the defendant relies
    on that specifically provide for certain jury instructions,
    under § 54-1o, when the police fail to record a custodial
    interrogation, our legislature has provided that such
    statements are presumed inadmissible unless the state
    can establish, by a preponderance of the evidence, spe-
    cific criteria to overcome the presumption. In State v.
    Lockhart, supra, 
    298 Conn. 537
    , we left for the legisla-
    ture the ‘‘weighing and balancing [of] the benefits and
    drawbacks of an electronic recording requirement,’’ and
    to create ‘‘the parameters of such a rule.’’ Id., 570. The
    legislature did not include a requirement in § 54-1o that
    the trial court give a specific instruction when the state
    successfully overcomes the presumption of inadmissi-
    bility. See, e.g., McCoy v. Commissioner of Public
    Safety, 
    300 Conn. 144
    , 155, 
    12 A.3d 948
     (2011) (‘‘[o]ur
    case law is clear . . . that when the legislature chooses
    to act, it is presumed to know how to draft legislation
    consistent with its intent and to know of all other
    existing statutes’’ (internal quotation marks omitted)).
    We therefore decline the defendant’s request that we
    exercise our supervisory authority to go beyond the
    legislature’s prescribed sanction and require trial courts
    to give a special instruction in every case in which
    the police fail to record custodial interrogations. If the
    legislature’s membership wants to revisit this issue and
    to incorporate a specific instruction along the lines that
    other state legislatures have incorporated, they are, of
    course, free to do so.
    We take this opportunity to emphasize, however, that
    it is well within the trial court’s discretion to give a
    specific, cautionary instruction when the police fail to
    record a custodial interrogation in violation of § 54-1o
    (b). As we have explained, ‘‘[i]t is within the province,
    and may be within the duty, of the trial judge to not
    only call attention to the evidence adduced, but [also]
    to state to the jury in the charge his [or her] own opinion
    of the nature, bearing and force of such evidence.’’
    (Internal quotation marks omitted.) State v. Lemoine,
    
    233 Conn. 502
    , 510–11, 
    659 A.2d 1194
     (1995); see, e.g.,
    id., 511 (‘‘generally the extent to which the [trial] court
    should discuss the evidence in submitting a case to the
    jury is, so long as in criminal cases the jury [is] not
    directed how to find [its] verdict, within the discretion
    of the trial judge’’ (emphasis omitted; internal quotation
    marks omitted)); State v. Anderson, 
    212 Conn. 31
    , 49,
    
    561 A.2d 897
     (1989) (‘‘[t]he trial court, like the jury,
    may assess a witness’ credibility and, if relevant, may
    comment on it’’); State v. Cari, 
    163 Conn. 174
    , 182, 
    303 A.2d 7
     (1972) (‘‘[o]n numerous occasions this court has
    stated that the trial court in a criminal case may, in its
    discretion, make fair comment on the evidence and
    particularly on the credibility of witnesses’’).
    When the police fail to record a custodial interroga-
    tion in violation of § 54-1o (b), and the defendant
    requests it, the trial court would be acting within its
    discretion to instruct the jury that it is the law of this
    state to record statements made during a custodial
    interrogation of a person under investigation for or
    accused of a class A or B felony and that the jury may
    consider the absence of a recording in evaluating the
    evidence relating to the individual’s statement obtained
    in violation of that law.
    Because trial courts already have the discretion to
    give a cautionary instruction under existing case law,
    we decline to create a new supervisory rule requiring
    a special instruction in all cases in which the police fail
    to comply with the recording mandate in § 54-1o (b).
    The judgment of the Appellate Court is affirmed.

    General Statutes § 54-1o provides in relevant part: ‘‘(b) An oral, written
    or sign language statement of a person under investigation for or accused
    of a capital felony or a class A or B felony made as a result of a custodial
    interrogation at a place of detention shall be presumed to be inadmissible
    as evidence against the person in any criminal proceeding unless: (1) An
    electronic recording is made of the custodial interrogation, and (2) such
    recording is substantially accurate and not intentionally altered.
    ***
    ‘‘(d) If the court finds by a preponderance of the evidence that the person
    was subjected to a custodial interrogation in violation of this section, then
    any statements made by the person during or following that nonrecorded
    custodial interrogation, even if otherwise in compliance with this section,
    are presumed to be inadmissible in any criminal proceeding against the
    person except for the purposes of impeachment.
    ‘‘(e) Nothing in this section precludes the admission of:
    ***
    ‘‘(2) A statement made during a custodial interrogation that was not
    recorded as required by this section because electronic recording was
    not feasible;
    ‘‘(3) A voluntary statement, whether or not the result of a custodial interro-
    gation, that has a bearing on the credibility of the person as a witness;
    ***
    ‘‘(6) A statement made during a custodial interrogation by a person who
    requests, prior to making the statement, to respond to the interrogator’s
    questions only if an electronic recording is not made of the statement,

    agreeing to respond to the interrogator’s question only if a recording is not
    made of the statement;

    The concurrence concludes that the voluntariness inquiry under § 54-1o
    is purely evidentiary because ‘‘the legislature does not establish constitu-
    tional requirements.’’ Our conclusion that the voluntariness inquiry under
    § 54-1o (h) is constitutional does not suggest that the legislature has created
    a constitutional requirement. Specifically, we do not conclude that the legis-
    lature has created a constitutional right to the recording of a custodial
    interrogation. Nor do we conclude that recording a custodial interrogation
    is sufficient, in itself, to establish voluntariness. Rather, in passing § 54-1o,
    the legislature referenced and incorporated the previously existing voluntari-
    ness requirement that the state already had the burden of proving. The
    recording of the custodial interrogation is simply a means to prove or
    disprove voluntariness. As the concurrence notes, the voluntariness require-
    ment contained in § 54-1o (h) ‘‘overlap[s] or track[s]’’ the due process require-
    ment of voluntariness. The voluntariness requirement in the statute does
    track the traditional constitutional voluntariness requirement. It does not
    create a new constitutional right; it simply incorporates what the state was
    already required to prove. In short, the statute provides that no statement
    given during a custodial interrogation, obtained in violation of the recording
    mandate, could be admitted into evidence in the absence of a showing that
    the police followed the long recognized, constitutional requirement that
    such a statement be given voluntarily. The only requirement that the statute
    does create is that the state must also prove the reliability of such a state-
    ment. As we discuss, that requirement is an evidentiary inquiry.
    Under the concurrence’s interpretation of the statute, the state would
    have a lower, evidentiary burden with respect to proving voluntariness when
    the police fail to record a custodial interrogation in violation of the statute.
    We decline to construe the statute to create such an anomalous result. See,
    e.g., Kelly v. New Haven, 
    275 Conn. 580
    , 616, 
    881 A.2d 978
     (2005). Just as
    the legislature cannot create a constitutional right, neither can it lower the
    state’s burden of proof. Moreover, the consequence of concluding that the
    voluntariness inquiry is merely evidentiary is that a trial court’s determina-
    tion of voluntariness is entitled to substantial deference on appeal. We
    decline to create two different standards for reviewing the voluntariness of
    a statement given during a custodial interrogation.
    4
    The defendant does not appear to dispute that the reliability inquiry
    under § 54-1o (h) is an evidentiary question.
    5
    The defendant does not claim that reliability is a constitutional matter
    under the state constitution. Accordingly, we have no occasion to consider
    whether our state constitution provides greater protection than the federal
    constitution. See, e.g., State v. Pinder, 
    250 Conn. 385
    , 418 n.31, 
    736 A.2d 857
     (1999).
    6
    The defendant does not challenge the validity of the Miranda warning
    he was given at the time of his arrest.
    7
    We acknowledge that this second acknowledgment of understanding did
    not occur until after the interrogation was under way, and thus it cannot,
    in and of itself, serve as the basis from which to conclude that the defendant
    understood and waived his rights. But the evidence establishes that the
    defendant acknowledged that he understood his rights at 5:30 a.m., and that
    he still understood his rights at approximately 1 p.m., and there is no evidence
    in the record to suggest that he suffered a lapse in that understanding at
    any point in between.
    8
    The record does reflect, contrary to the defendant’s assertions, that the
    trial court considered Merritt’s conduct. For example, the court stated that,
    although Merritt was aware that the law required recording, he had not
    acted in bad faith.
    9
    We emphasize the importance of recording custodial interrogations, as
    required by § 54-1o. Such recordings enable the fact finder to view the
    circumstances of the interrogation for himself or herself and provide strong
    evidence to determine both the voluntariness and reliability of a defen-
    dant’s statement.
    10
    The corpus delicti is ‘‘the occurrence of the specific kind of loss or
    injury embraced in the crime charged.’’ (Internal quotation marks omitted.)
    State v. Leniart, supra, 
    333 Conn. 97
    . For instance, ‘‘[i]n a homicide case,
    the corpus delicti is the fact of the death, [regardless of whether] feloniously
    caused, of the person whom the accused is charged with having killed or
    murdered.’’ (Internal quotation marks omitted.) 
    Id.
     The corpus delicti rule,
    also known as the corroboration rule; 
    id.,
     97 n.5; is a common-law rule that
    ‘‘generally prohibits a prosecutor from proving the [fact of a transgression]
    based solely on a defendant’s extrajudicial statements.’’ (Internal quotation
    marks omitted.) Id., 97. Thus, in a murder trial, for example, the rule would
    prevent the state from relying solely on the defendant’s statement that he
    or she had killed a victim to prove that the victim was dead.
    Although the corpus delicti rule, like § 54-1o, exists, in part, to prevent
    the admission of false confessions into evidence, the primary purpose of
    the corpus delicti rule is to ‘‘avoid the patent injustice of convicting an
    innocent person . . . of an imaginary crime.’’ (Emphasis added.) Id., 105.
    That is, the rule requires independent evidence not to confirm that the
    defendant is the one who committed the crime, but to confirm that the
    crime charged actually occurred. It exists to provide reassurance that the
    crime took place, not that the defendant was the one responsible.
    11
    To the extent that the defendant argues in his reply brief that the state
    was required to introduce independent evidence of the corpus delicti of
    strangulation and assault for the defendant’s statement to be admissible,
    the defendant misinterprets the evolution of our corpus delicti rule into its
    modern form, the trustworthiness doctrine. Indeed, under the former rule,
    the state would have had to introduce independent evidence of the corpus
    delicti itself for the statement to be admissible. But under the modern rule,
    that is no longer the case. As we have previously explained, the state no
    longer must establish the corpus delicti of a crime through extrinsic evi-
    dence; it need only ‘‘introduce substantial independent evidence [that] would
    tend to establish the trustworthiness of the [defendant’s] statement.’’ (Inter-
    nal quotation marks omitted.) State v. Leniart, supra, 
    333 Conn. 113
    . That
    independent evidence need not corroborate the corpus delicti itself.
    12
    The defendant also mentions in his brief that, ‘‘[u]nder the circumstances
    here, it was plain error not to inform the . . . jury that the Enfield police
    violated the recording mandate . . . .’’ To the extent the defendant is
    asserting a claim under the plain error doctrine, we note that ‘‘[t]he plain
    error doctrine, which is codified at Practice Book § 60-5, is an extraordinary
    remedy used by appellate courts to rectify errors committed at trial that,
    although unpreserved, are of such monumental proportion that they threaten
    to erode our system of justice and work a serious and manifest injustice
    on the aggrieved party. . . . In addition, the plain error doctrine is reserved
    for truly extraordinary situations [in which] the existence of the error is so
    obvious that it affects the fairness and integrity of and public confidence
    in the judicial proceedings. . . . Plain error is a doctrine that should be
    invoked sparingly. . . . Implicit in this very demanding standard is the
    notion . . . that invocation of the plain error doctrine is reserved for occa-
    sions requiring the reversal of the judgment under review. . . . [Thus, an
    appellant] cannot prevail under [the plain error doctrine] . . . unless he
    demonstrates that the claimed error is both so clear and so harmful that a
    failure to reverse the judgment would result in manifest injustice.’’ (Emphasis
    added; internal quotation marks omitted.) State v. Diaz, 
    302 Conn. 93
    , 101,
    
    25 A.3d 594
     (2011). Given that the defendant is asking us to invoke our
    supervisory authority to require a jury instruction that was not previously
    required, we fail to see how the trial court’s failure to sua sponte give that
    instruction constituted plain error. See, e.g.,

    The defendant also notes that New Jersey and Massachusetts require
    special instructions when the police fail to follow law requiring that custodial
    interrogations be recorded. New Jersey’s electronic recordation law provides
    that ‘‘[t]he failure to electronically record a defendant’s custodial interroga-
    tion in a place of detention shall be a factor for consideration by the trial
    court in determining the admissibility of a statement, and by the jury in
    determining whether the statement was made, and if so, what weight, if
    any, to give to the statement.’’ N.J. Court Rules 3:17 (d); see State v. Hubbard,
    
    222 N.J. 249
    , 263, 
    118 A.3d 314
     (2015) (‘‘[f]ollowing a comprehensive study
    of ‘whether and how to implement the benefits of recording electronically
    part, or all, of custodial interrogations,’ State v. Cook, 
    179 N.J. 533
    , 561, 
    847 A.2d 530
     (2004), the [c]ourt adopted [r]ule 3:17 in 2005’’). Subsection (e) of
    rule 3:17 provides in relevant part that, ‘‘[i]n the absence of an electronic
    recordation . . . the court shall, upon request of the defendant, provide
    the jury with a cautionary instruction.’’ (Emphasis added.) N.J. Court Rules
    3:17 (e). ‘‘[A] report issued by the New Jersey Supreme Court Special Com-
    mittee on Recordation of Custodial Interrogations in 2005 recommended
    an instruction that the jury has ‘not been provided with a complete picture
    of all of the facts surrounding the defendant’s alleged statement and the
    precise details of that statement.’ ’’ State v. Lockhart, supra, 
    298 Conn. 564
    n.11. Similarly, the Massachusetts Supreme Judicial Court has explained
    that defendants are ‘‘entitled (on request) to a jury instruction advising that
    the [s]tate’s highest court has expressed a preference that such interroga-
    tions be recorded whenever practicable, and cautioning the jury that,
    because of the absence of any recording of the interrogation in the case
    before [it], [it] should weigh evidence of the defendant’s alleged statement
    with great caution and care.’’ (Emphasis added.) Commonwealth v. DiGiam-
    battista, 
    442 Mass. 423
    , 447–48, 
    813 N.E.2d 516
     (2004).
    We note that, in both New Jersey and Massachusetts, the defendant must
    request the jury instruction. In the present case, the defendant made no
    such request. Additionally, the instruction adopted in DiGiambattista was
    an effort by the Massachusetts high court to find a middle ground between
    excluding unrecorded confessions and doing nothing to ameliorate the harm
    to defendants. See
