Howard was referring to a conversation he taped when Michelle Ghent was on the phone threatening to telling various people he had an STD.
He also testified he felt pressure to sign the settlement agreement, giving her an unusually large sum of money and also because she threatened to release a sex tape featuring him and another woman.
According to TMZ reports, Howard blew his nose as he fought back tears on the stand, taking deep breaths as he testified.
He also testified that his wife was always jealous about his scenes with other women on TV especially the make out scene with Jennifer Hudson in the movie-Winnie Mandela. He said she flew into a rage and threw food at him while they were in South Africa.
He also testified that they were no longer sexually compatible once he tried becoming a Jehovah's witness and applied bible principles to his sex life.
He's trying to undo the settlement, giving her $5,800 a month in spousal support and a chunk of his "Empire" earnings, on grounds he signed the doc under extreme duress.
