Ebert will debut the new voice -- a work in progress -- to give his Oscar predictions on Oprah's show.
He's used several computer voices since losing his ability to speak due to a series of health issues. A company in Scotland is recreating Ebert's tones and vocal patterns by using recordings of reviews and various shows.
Ebert says the test results have made him "ridiculously happy." He looks forward to the time when he can use the process to talk with his wife, Chaz, and their grandchildren-- and tell fans what he thinks about movies in webcasts-- in his own voice.
The Oprah Winfrey Show airs at 9 a.m. on ABC7 Chicago.
