I mean, if it is your voice, can’t you just record it directly? Isn’t that better than going through an artificial middle man that has to be primed first with some recording of yours?

It would be a huge time saver. Typically a pro does around 100 lines per hour, an amateur doing multiple takes would be significantly slower. So a character with 1000 lines could easily be 20-30 hours of work, just for a first draft. It would be pretty amazing to be able to just revise the script and auto-generate a new recording, even if the quality is only 90% there.

Just like with image generation models, this will massively raise the bar for what amateurs can do with a limited budget and limited time. It's hard to justify spending thousands of dollars on voice acting and art for a hobby project, but now amateurs can get something that is 90% there and substitute professional work if the project takes off.
