The next time you see a movie or TV show that was dubbed from a foreign language, the voices you hear may not belong to actors who rerecorded dialogue in a sound booth. In fact, they may not belong to actors at all.
Highly sophisticated digital voice manufacturing is coming, and entertainment executives say it could bring a revolution in sound as industry-changing as computer graphics were for visuals. New companies are using artificial intelligence to create humanlike voices from samples of a living actor’s voice—models that not only can sound like specific performers, but can speak any language, cry, scream, laugh, even talk with their mouths full. At the same time, companies are refining the visual technology so actors look like they are really speaking.
