That’s obviously way better than any TTS before it, but I still wouldn’t want to listen to it for more than a few minutes. In these two sentences I can already hear some of the “AI quirks” and the longer you listen, the more you start to notice them.
I listen to a lot of AI celeb impersonations and they all sound like the same machine with different voice synthesizers. There’s something about the prosody that gives it away, every sentence has the same generic pattern.
Humans are generally more creative, or more monotonous, but AI is in a weird inbetween space where it’s never interested and never bored, always soulless.
