Beyonce, we'll tell you why she's smiling in this video. But first, now the guy behind the manti te'o scandal is now recreating the voice. Is it really him? Abc's linsey davis consulted some experts. In an exclusive interview with dr. Phil, ronaiah tuiasosopo not only admits that he was the mastermind behind the manti te'o girlfriend hoax. But he watched as this 22-year-old man goes behind this privacy screen and transforms his voice into the fictitious female character he created. Here's the original and here's ronaiah tuiasosopo's version. According to dr. Phil's voice print experts. The first recordings behind the screen pointed toward a match. But dr. Phil was still skeptical. Again, here's a different voice mail. I don't know who answered your phone. And I don't care. Reporter: Here's ronaiah tuiasosopo's version. I don't know who answered your phone and I don't care. Reporter: While dr. Phil said that all three experts confirmed that his voice matched the voice on the voice mail. We asked our own expert. From the three voice mails that have been released there really are no signs that I think te'o could have heard to give away that he wasn't talking to a woman and he was talking to a man. Reporter: Watch as we compare the two voice samples side by side. I got here. I'm getting ready for my first session. Just wanted to call you and keep you posted.
