I have an idea for the practice that could help us better explore practical uses. Basically, a company may train an AI off an actor’s voice, but that actor retains full non-transferable ownership/control of any voices generated from that AI.
So, if a game is premiering a new game mode that needs 15 new lines from a character, but their actor is busy drinking Captain Morgan in their pool, the company can generate those 15 lines from AI, but MUST have a communication with the actor where they approve the lines, and agree on a price for them.
It would allow for dynamic voice moments in a small capacity, and keep actors in business. It would still need some degree of regulation to ensure no one pushes gross incentives.
