Video games and movie generation I think mostly. Llms will probably be running constantly in the background in next gen rpgs so players can have actual conversations with NPCs. Voice cloning isn’t necessary but you can get better mannerisms with it currently I’m pretty sure.

I can also see celebrities and voice actors wanting to sell their voice. It doesn’t require much work and voice actors are talented enough that they can offer personalized characters with different speech patterns and what not.
