The voice on telephone messages left for Manti Te'o matches that of the 22-year-old man who says he posed as a woman in carrying on a relationship - by e-mail and over the phone - with the Notre Dame linebacker, according to the "Dr. Phil" show.
"They all say, with scientific certainty, that Ronaiah Tuiasosopo is the female voice in those recordings," host Phil McGraw said, citing conclusions by forensic voice analysts with three independent contractors.
That conclusion supports Tuiasosopo's assertion that, posing as a woman, he was involved in a relationship with Te'o, who had not known that his love interest was a man.
Te'o rose to prominence while leading Notre Dame's Fighting Irish to an undefeated regular season. This year's Heisman Trophy runner-up, he told interviewers in September and October that his grandmother and girlfriend, whom he described as a 22-year-old Stanford University student, had died within hours of each other.
