And tonight, we are learning more about the hoax that fooled manti te'o. And the man who was allegedly behind it all. We are hearing the phone calls, the ones that te'o thought were the girl of his dreams but in fact, they were an imposter. Abc's matt gutman has the tape. Reporter: Tonight for the first time, the voice that charmed and tormented manti te'o, the notre dame football star releasing voicemails he thought were from his girlfriend. We now know she never existed. Hi, I am just letting you know I got here. I miss you. I love you, bye. Doesn't it sound like a girl? It does. It sounds like a girl, doesn't it? Yeah. Reporter: But could the sweet voice on the "katie" show actually be the voice of this man? Hey, what's up, everyone, this is ronaiah. I'm truly blessed and excited to share music with you. Reporter: "The daily news" reports ronaiah tuiasosopo's attorney says his client was the one speaking to te'o all along. Tuiasosopo, seen in these chase chan music videos, was a former star high school quarterback, who te'o claims created the beautiful, jealous and totally fictitious lennay kekua. I don't know who answered your phone. And I don't care. Reporter: So convincing, te'o would spend up to eight hours bearing his soul to her. Over 1,000 calls. What's more, abc news has learned, tuiasosopo may have been duping people for years. This polynesian beauty queen says this lennay kekua contacted her online back in 2008. I think what made her seem real was just the persistence in the messages, just being consistent at the same time. Reporter: She says when they were supposed to meet, someone else showed up. Ronaiah tuiasosopo. But what might drive someone to attempt such an elaborate hoax? It's both a very weak ego and a definite character distorter with a tremendous need to manipulate. Reporter: The daily news" reports tuiasosopo's attorney insists his client was just a person trying to reach out and communicate and have a relationship. Matt gutman, abc news, los angeles.
