The New York Post last week reported that a female cousin of Ronaiah Tuiasosopo, Tino Tuiasosopo, was the person who was Kekua's voice in the phone calls. Tuiasosopo's lawyer, however, told the New York Daily News last week that his client was the voice of Kekua.
A week later, McGraw played the same tapes, then told Tuiasosopo, "I think it's important for people to see the voice control and see you speak in the female voice."
"I can't even if I tried," Tuiasosopo responded. "There's a whole lot that went into pushing me to do that, to go to that extreme consistently. And for me to just do it like -- can you do the voice? -- Even if I try, it just doesn't come out right."
McGraw then told Tuiasosopo that he contacted private contractors that do voice work for the FBI and the Secret Service.
"I gave them that voice mail," McGraw said. "And I gave them your voice. And I had them do a highly scientific spectra analysis of our voice and score them both. They looked at everything from voice intonation to tonal qualities."
The voices are scored on a scale from 0 to 100, with anything 60 and above constituting a match. Tuiasosopo's voice scored a 16 in the analysis.
"They said the chance that you were the person on that voicemail is like 1 in 10 million," McGraw said, "that it is not you, not even possible. You're telling me that you're telling the truth and I'm telling you that the best scientific analysis in the world is saying that it is not. I say, 'Just do the voice.' "
"I've never done it in front of people," Tuiasosopo said. "Ever single time I've ever spoken that voice, I was never by people. I was in dark room away from people."
Part II, which airs Friday at 3 p.m., locally on WSBT-TV, picks up at that point.
