Depending on the actual terms of the contract, I don't see how this is terribly different than getting a sound-a-like voice actor to do an impression of that rendition of the character. Would the estate still be making money on that voice's use? Would it augment another human actor's voice in the same way that they had to have an actual human when they filmed the Princess Leia shot for Rogue One?
Seems like the devil (or not) is in the details of how this tech would be used.
It means the sound a like wouldn't get paid or employed. And the company would milk the ai voice for free for as long as it's in business. "reducing overhead" and fucking over the voice actor industry. Which is already pretty raw from lack of lube.
Fair. There will definitely be disruptions and not all of them I'd consider positive, even though I'm pretty pro-AI in general. Things like this are going to push more and more sectors of the economy and human life to the tipping point. I fear that we'll eventually be faced with the fork in the road leading to Star Trek communist-utopia or barren capitalistic hellscape with a few rulers with AI armies to keep the plebs out of their hair, and we'll choose the latter.
