Ronaiah Tuiasosopo is very sorry - and, apparently, very skilled at sounding like a woman over the phone.

The young, troubled man behind the Manti Te'o girlfriend hoax appeared yesterday on Dr. Phil and, after insisting he stand behind a curtain for a sense of privacy, performed for viewers the voice he used as Lenny Kekua in this drawn-out scheme to fool the linebacker.

In a taped interview with Katie Couric, which will air tomorrow on that host's talk show, Manti Te'o admits to at least one time when he lied about the existence of his girlfriend, Lennay Kekua.

Asked by Couric whether he was in on the hoax, Te'o says no - but he did mislead reporters on two occasions after receiving a call on December 6 from someone claiming to be Kekua, who Te'o thought to have died two months earlier.
