¶1 Following a bench trial, the trial court found John Garrett Smith guilty of second degree attempted murder and second degree assault, each with a domestic violence sentencing enhancement. He appeals these convictions and the enhancements, arguing that the trial court erred when it ruled that a voice mail recording containing part of a domestic dispute between him and his spouse, Sheryl Smith, was admissible and not in violation of Washington’s privacy act, RCW 9.73.030. He also raises myriad arguments in his statement of additional grounds (SAG).

¶2 In the published portion of this opinion, we hold that the trial court erred in admitting the voice mail recording because its contents contained a private conversation that was recorded without the parties’ consent. Because the trial court specifically relied on that recording to find John 1 guilty of second degree attempted murder, its erroneous admission was prejudicial to that conviction. However, the improper admission of the recording had no prejudicial effect on the second degree assault conviction. Accordingly, we reverse and remand John’s second degree attempted murder conviction and affirm his second degree assault conviction.

*228 ¶3 In the unpublished portion of the opinion, we address and reject John’s SAG claims.

FACTS

¶4 John and Sheryl married in 2011 and lived in Vancouver with Sheryl’s daughter, Skylar Williams. On June 2, 2013, John and Sheryl were in their residence drinking. They became intoxicated and began to argue, which prompted Williams to leave the house. While Sheryl and John were alone, John began to beat and strangle Sheryl, who lost consciousness due to the strangling.

¶5 Sometime during the attack, John used the residence’s landline telephone to try to locate his cell phone. Unable to do so, he was unaware that his actions activated his cell phone’s voice mail function, which started recording part of the dispute. In that recording, John is heard yelling insults at Sheryl and demands related to locating his cell phone. Sheryl responded to these statements by screaming unintelligibly or asking him to stop or leave her alone. At one point during the recording, Sheryl tells John to “[g]et away,” to which he responds, “No way. I will kill you.” Report of Proceedings (RP) at 241-43.

¶6 Shortly after the voice mail was recorded, John left the residence. Sheryl called 911 and reported that John had beaten her. During the 911 call, Williams returned home and saw that Sheryl’s head was bloodied and swollen. Ly Rota Yong, a police officer with the Vancouver Police Department, arrived at the residence, and Sheryl was transported to the hospital. At some point after Williams arrived home, she retrieved John’s cell phone and listened to the voice mail. At the hospital, Williams played the voice mail recording for Yong, who took the phone into possession.

¶7 John was later arrested and charged with first degree attempted murder (domestic violence), second degree attempted murder (domestic violence), first degree assault (domestic violence), and second degree assault (domestic violence).

*229 ¶8 Before trial, John moved to suppress the cell phone voice mail recording based on RCW 9.73.030. The trial court held a CrR 3.6 hearing, denied his motion, and entered findings of fact and conclusions of law. Pertinent to his assignments of error on this appeal, the trial court made the following conclusions of law:

7. RCW 9.73.030(l)(a) does not apply to this case because the people in the room where the recording took place, [Sheryl] and [John], were not attempting to communicate by electronic means. Neither party attempted to communicate by electronic means.

8. RCW 9.73.030(l)(b) applies when two people are having a private, non-electronic, conversation and a third party attempts to record or intercept that conversation.

9. RCW 9.73.030(l)(b) does not apply to this case because this information was recorded by [Johnfs phone inadvertently. At the time this information was recorded, nobody was trying to intercept or record what was occurring.

11. At the time [Williams] discovered the phone and opened it, neither of the activities prohibited by RCW 9.73.030 were taking place. [Williams] was not violating that statute when she opened the phone and listened to its contents.

13. None of the information that was gathered up until the point that Officer Yong listened to the phone recording was gathered illegally.

Clerk’s Papers (CP) at 92-93.

¶9 At John’s bench trial, he, Sheryl, Williams, several police officers, and expert witnesses testified. The recorded voice mail, 911 phone calls, and photographs of Sheryl’s injuries were admitted into evidence. The trial court entered findings of fact and conclusions of law, finding John guilty of second degree attempted murder and second degree assault, *230 both with domestic violence enhancements. 2 The trial court found that the convictions merged, so it sentenced him only on the second degree attempted murder conviction.

ANALYSIS

Privacy Act Violation

1. Standard of Review and Legal Principles

¶11 John does not challenge any of the trial court’s findings of fact related to the CrR 3.6 hearing, and unchallenged findings are deemed verities on appeal. State v. O’Neill, 148 Wn.2d 564, 571, 62 P.3d 489 (2003). He does challenge several of the trial court’s conclusions of law, which we review de novo. State v. Roden, 179 Wn.2d 893, 898, 321 P.3d 1183 (2014). We review conclusions of law to determine whether they are legally correct and whether they are supported by the findings. State v. Cole, 122 Wn. App. 319, 323, 93 P.3d 209 (2004); see McCleary v. State, 173 Wn.2d 477, 514, 269 P.3d 227 (2012).

¶12 Washington’s privacy act, chapter 9.73 RCW, is “one of the most restrictive electronic surveillance laws ever promulgated,” significantly expanding the minimum standards of its federal counterpart and offering a greater degree of protection to Washington residents. Roden, 179 Wn.2d at 898. RCW 9.73.030 provides in pertinent part,

(1) Except as otherwise provided in this chapter, it shall be unlawful for any individual ... to intercept, or record any:

(a) Private communication transmitted by telephone, telegraph, radio, or other device between two or more individuals between points within or without the state by any device electronic or otherwise designed to record and/or transmit said communication regardless how such device is powered or *231 actuated, without first obtaining the consent of all the participants in the communication;

(b) Private conversation, by any device electronic or otherwise designed to record or transmit such conversation regardless how the device is powered or actuated without first obtaining the consent of all the persons engaged in the conversation.

“Any information obtained in violation of RCW 9.73.030 .. . shall be inadmissible in any civil or criminal case.” RCW 9.73.050. 3

2. Private Communication

¶13 John assigns error to conclusion 7 from the trial court’s CrR 3.6 ruling, in which it ruled that RCW 9.73-.030(l)(a) did not apply. In this, the trial court was correct.

¶14 Unequivocally, RCW 9.73.030(l)(a) requires a “[p]rivate communication transmitted by telephone, telegraph, radio, or other device between two or more individuals.” (Emphasis added); see also Roden, 179 Wn.2d at 898-900 (text messages between two cell phones); State v. Christensen, 153 Wn.2d 186, 191-92, 102 P.3d 789 (2004) (telephone calls); State v. Townsend, 147 Wn.2d 666, 672, 57 P.3d 255 (2002) (e-mails, instant messaging). The unchallenged findings 1 and 2 and the evidence supporting them show that the voice mail feature recorded John and Sheryl communicating in person. They were not attempting to communicate through any device that would make the voice mail recording subject to RCW 9.73.030(l)(a). Accordingly, we hold that the trial court did not err in concluding that RCW 9.73.030(l)(a) was inapplicable.

*232 3. Private Conversation

¶15 John raises three issues related to the trial court’s conclusions 8, 9, 11, and 13 pertinent to RCW 9.73-.030(l)(b): (1) whether the recorded voice mail’s contents are a conversation, (2) if the contents are a conversation, whether it was private, and (3) if a private conversation, whether it was recorded or intercepted. For the following reasons, we hold that John recorded a private conversation in violation of RCW 9.73.030.

A. Conversation

¶16 To begin with, the parties dispute whether the contents of the recorded voice mail are a conversation under RCW 9.73.030(1)(b). Because the privacy act does not define “conversation,” we may use a dictionary to discern the plain meaning of that term. Newton v. State, 192 Wn. App. 931, 937, 369 P.3d 511, review denied, 186 P.3d 1003 (2016). Webster’s Third New International Dictionary 498 (2002) defines “conversation” in pertinent part as an “oral exchange of sentiments, observations, opinions, ideas : colloquial discourse.”

¶17 However, the State contends that State v. Smith, 85 Wn.2d 840, 540 P.2d 424 (1975) complicates this dictionary definition. In Smith, the Washington Supreme Court held that the trial court did not err in admitting a tape that had recorded the moments immediately before Nicholas Kyrea-cos, the victim, was killed. Id. at 842-43, 846-47. Kyreacos was wearing a device to record his encounter with the defendant. Id. at 843. The recording begins with Kyreacos observing his surroundings while walking to meet with the defendant. Id. at 844. After Kyreacos’ statement that “ ‘[everything looks quite normal,’ ” the Smith court described the pertinent contents of the tape recording in the following terms:

Then, suddenly are heard the sounds of running footsteps and shouting, the words “Hey!” and “Hold it!”, Kyreacos saying *233 “Dave Smith,” and a sound resembling a gunshot. The running stops, and Smith tells Kyreacos to turn around. Kyreacos asks, “What’s the deal?” Smith replies, “You know what the deal is. I’ll tell you one thing baby, you have had it.”

Several more words are exchanged, not all of which are clearly intelligible, about whether Smith has “a charge.” Then Kyreacos asks, “If you wanted me, why didn’t you come to see me?” Smith replies, “I’ll tell you why.” A moment later, another shot is heard. The quality of the recording becomes “tinny.” (There was expert testimony that this shot damaged the microphone.) Then Kyreacos, screaming, repeatedly begs for his life. More shots are fired. There is a slight pause, two more shots are heard, then certain unclear sounds, then silence. After a period of nearly complete silence, a voice is heard to say, “We’ve already called the police.” Another voice says, “Hey, I think this guy’s dead, man.” Afterward, the tape records police sirens and the sounds of the officers investigating.

Id. at 844-45. Based on this recording, the Smith court held that

the material recorded was clearly “private conversation” within the simple meaning of that term. However, the special circumstances of the present case compel us to arrive at a different result. We are convinced that the events here involved do not comprise “private conversation” within the meaning of the statute. Gunfire, running, shouting, and Kyreacos’ screams do not constitute “conversation” within that term’s ordinary connotation of oral exchange, discourse, or discussion. We do not attempt a definitive construction of the term “private conversation” which would be applicable in all cases. We confine our holding to the bizarre facts of this case, and find that the tape does not fall within the statutory prohibition of RCW 9.73.030, and thus its admission is not prohibited by RCW 9.73.050.

Id. at 846-47.

¶18 The Smith court made clear that it was confining its holding to its specific facts and that its definition of “conversation” was not applicable in all cases. Because of its sui generis nature, Smith has little bearing on the case before us. Nevertheless, the State argues that the contents *234 of the voice mail recording here are legally indistinguishable from and as unique as the recording in Smith. We disagree.

¶19 Unlike Smith, there was a much greater oral exchange of words and sentiments between John and Sheryl. Examples within the voice mail recording include (1) John calling Sheryl a “[flat [b]itch” and Sheryl responding, “Stop,” (2) John asking, “Where is my phone?” and Sheryl screaming, “Look what you have done to me!” and (3) John telling Sheryl, “I will kill you,” to which Sheryl responds, “I know.” RP at 241-43. In this final example’s complete context, the exchange particularly shows a clear dialogue between the two individuals:

John: You think you’re bleeding? ... You’re the most fucked up person. Give me back the phone.

Sheryl: Get away.

John: No way. I will kill you.

Sheryl: I know.

John: Did you want to kill me? Give me back my phone.

Sheryl: No. Leave me alone.

RP at 241-43. These examples from the voice mail recording are unmistakably verbal exchanges falling within the definition of “conversation.”

¶20 We agree with the State that, similar to Smith, some parts of the recorded voice mail may fall outside the definitional scope of conversation, particularly Sheryl’s unintelligible screams. Standing alone, Sheryl’s screams would not constitute a conversation. However, these screams were responsive to statements that John was making to Sheryl and were scattered throughout the entire dispute, which contained repeated verbal exchanges between the two individuals as outlined above. Within this context, Sheryl’s screams serve as an expression of sentiments *235 responsive to John’s yelling and thus constitute part of a conversation. 4

¶21 For the above reasons, the contents of the recorded voice mail constituted a conversation under RCW 9.73.030(l)(b).

B. Private

¶22 Both parties dispute whether the conversation between John and Sheryl was private under RCW 9.73-.030(l)(b). For the following reasons, we hold that the conversation was private.

¶23 “A communication is private (1) when parties manifest a subjective intention that it be private and (2) where that expectation is reasonable.” State v. Kipp, 179 Wn.2d 718, 729, 317 P.3d 1029 (2014). In determining a subjective intention of privacy, a party does not need to explicitly state such an intention during the conversation; rather, it can be inferred from the facts and circumstances of the specific case. Id. In ascertaining whether an expectation of privacy is reasonable, we examine the following factors: duration and subject matter of the conversation, the location of the conversation, the presence or potential presence of third parties at the conversation, and the role of the nonconsenting party and his or her relationship to the consenting party. Id. As with subjective intent, “[t] he reasonable expectation standard calls for a case-by-case consideration of all the facts.” Id. Because the trial court’s CrR 3.6 findings of fact are undisputed, we review de novo whether the conversation was private. Id. at 722-23.

¶24 Here, a domestic dispute occurred between two married persons in the privacy of their home. The dispute did not occur until Williams left, which signals a subjective intention and reasonable expectation that the conversation *236 would be private. Id. at 729-31. Of the factors set out above, the location of the conversation, the relationship between the parties, and the absence of third parties all declare the privacy of the conversation. None of the considerations in Kipp dispute its privacy. On these facts, we hold that John had a subjective intention and reasonable expectation that the conversation with Sheryl would be private.

C. Recording and Interception

¶25 Finally, related to conclusions 8, 9, 11, and 13, John contends that the trial court erred in ruling that the conversation was not recorded or intercepted.

¶26 In conclusion 11, the trial court ruled, “At the time [Williams] discovered the phone and opened it, neither of the activities prohibited by RCW 9.73.030 were taking place. [Williams] was not violating that statute when she opened the phone and listened to its contents.” CP at 93. In this, the trial court was correct. Williams did not record or intercept John’s conversation when she merely opened his phone and played the voice mail for the police. John himself was the one who enabled the device to record the private conversation. Williams may have accessed a device that happened to record or intercept a conversation, but John was the one who recorded the conversation. Thus, the trial court did not err in concluding that Williams did not record or intercept the conversation.

¶27 In conclusion 8, the trial court ruled that “RCW 9.73.030(l)(b) applies when two people are having a private, non-electronic, conversation and a third party attempts to record or intercept that conversation.” CP at 92 (emphasis added). The trial court erred in this conclusion.

¶28 RCW 9.73.030(1) by its plain language imposes its restraints on “any individual” without limitation to those not participating in the conversation. A broad and literal reading of this plain text is in step with the Supreme Court’s characterization of our privacy act as requiring the consent of all parties to a private conversation. Kipp, 179 *237 Wn.2d at 725. Further, although no case has held so directly, the case law has implied that no third party is required to record a conversation, i.e., a party to a private conversation can also be the person who impermissibly records the conversation. Id. at 723; Smith, 85 Wn.2d at 843, 846-47; State v. D.J.W., 76 Wn. App. 135, 139, 142, 882 P.2d 1199 (1994), aff’d sub nom. State v. Clark, 129 Wn.2d 211, 916 P.2d 384 (1996). Thus, John’s recording of this conversation can violate the privacy act, even though he was a party to it.

¶29 In conclusion 9, the trial court ruled that

RCW 9.73.030(l)(b) does not apply to this case because this information was recorded by [John]’s phone inadvertently. At the time this information was recorded, nobody was trying to intercept or record what was occurring.

CP at 92 (emphasis added). The trial court also erred in this conclusion.

¶30 Whether John inadvertently or purposely recorded himself is beside the point; the statute requires no specific mental state for a person to improperly record a conversation. Lewis v. Dep’t of Licensing, 157 Wn.2d 446, 465, 139 P.3d 1078 (2006); Haymond v. Dep’t of Licensing, 73 Wn. App. 758, 762, 872 P.2d 61 (1994). Although some cases involve a person who is both a party to a conversation and intentionally or knowingly records his or her own conversation, e.g., Kipp, 179 Wn.2d at 723, nothing in the plain language of RCW 9.73.030 imposes such a requirement. We are unwilling to risk compromising the scope of the privacy act by the doubtful implication of a mental state requirement from language saying nothing about a mental state. Therefore, the trial court erred by holding that John’s inadvertence in recording the private conversation removed his actions from the reach of the privacy act.

¶31 In conclusion 13, the trial court ruled that “[n]one of the information that was gathered up until the point that Officer Yong listened to the phone recording was gathered *238 illegally.” CP at 93. Because John recorded a private conversation without Sheryl’s consent, the trial court erred in this conclusion. 5

¶32 For these reasons, the trial court erred in conclusions 8, 9, and 13 and by admitting the voice mail recording at John’s trial.

4. Prejudice

¶33 Having concluded that the recorded voice mail was improperly admitted, we next turn to whether its admission was prejudicial to John’s trial.

Failure to suppress evidence obtained in violation of the [privacy] act is prejudicial unless, within reasonable probability, the erroneous admission of the evidence did not materially affect the outcome of the trial.

Christensen, 153 Wn.2d at 200. If the erroneous admission of evidence was prejudicial, we reverse. State v. Courtney, 137 Wn. App. 376, 383-84, 153 P.3d 238 (2007).

¶34 The trial court clearly relied on the voice mail recording in determining that John formed the intent to kill Sheryl, which was part of its basis for finding him guilty of second degree attempted 6 murder. 7 The trial court found:

4.1 [John] formed the intent to kill [Sheryl] and is heard telling [Sheryl] that “I will kill you” and then proceeds to beat her in the head and strangle her.

4.4 In the moment when [John] told [Sheryl], “I am going to kill you,” the Court finds beyond a reasonable doubt that killing *239 [Sheryl] was his exact intent. [John] did not say this because he was angry at [Sheryl], or for some other reason. He said it because he meant it.

CP at 86. Given these findings, we cannot say within reasonable probability that the trial court would have found John guilty of second degree attempted murder if the voice mail recording had been suppressed.

¶35 On the other hand, nothing in the trial court’s findings supporting the second degree assault conviction suggest that it relied on the voice mail recording. The voice mail was merely cumulative evidence supporting that conviction, considering that several witnesses testified to Sheryl’s injuries and corroborating pictures were admitted into evidence.

¶36 Accordingly, we reverse and remand the second degree attempted murder conviction 8 but affirm the second degree assault conviction.

¶37 A majority of the panel having determined that only the foregoing portion of this opinion will be printed in the Washington Appellate Reports and that the remainder shall be filed for public record pursuant to RCW 2.06.040, it is so ordered.

Review granted at 187 Wn.2d 1025 (2017).
