This is an exceptional use case!

Mr Beast talked about translating his videos to other languages to get more reach. This can be done for people with limited budget or just in general so people can watch videos without needing subtitles.

I wouldn't be surprised if we saw this incorporated into YT in the near future.

Another really good one would be for RPGs. Instead of clumsy approaches like "Hey Dragonborn" and whatnot, they could actually say your character's name out loud.

Right, and taking it one step further, LLMs in games with voice actors providing the basis for dynamic dialogue that sounds like it's coming from a person.
