Those are deepfakes that use A.I. to alter the face while following the original motion, changing the mouth movements to match new lines would be a totally different thing. And the Tarkin & Leia deepfakes are not seamless, they’re just a marked improvement over the dated CGI used originally, deepfaking Adam Driver would immediatly stand out as phony compared to the original footage.
I’m also weary of overusing the A.I. voice since it can’t 100% match Adam’s natural performance, though I guess it’s better to get as many samples as we can even if only a small fraction is actually used.
