Ebert to Debut 'New' Voice

A battle with throat cancer left film critic Roger Ebert without a voice, but technology has come to the rescue: Ebert will show off a text-to-audio computer program that “speaks” in his old voice on The Oprah Winfrey Show on Tuesday. The program, built by a Scottish company called CereProc, built the program using old recordings of Ebert, who hosted the television program At the Movies for years.
