Roger Ebert has not been able to speak for 4 years.

Until now.

In this video, Ebert and his wife, Chaz, hear his voice for the first time ... thanks to Ebert's MacBook and a Scottish company, called CereProc, that built his OWN text-to-speech voice from the many hours of footage from his old movie review TV shows.

Ebert lost his voice after post-surgical complications related to thyroid cancer.
