Recently I wanted an audiobook version of a book I was going to read, but it didn't exist. I put this together using Coqui-TTS and the voice sounds really good. It's not as good as Eleven Labs, but it's far better than anything else I had previously heard.

If anyone knows of better TTS synthesizers that I could use please let me know!
Thanks for sharing! This is something I'm interested in as well. There's also Piper TTS: https://github.com/rhasspy/piper
Quality seems fairly similar to Coqui-TTS, though maybe the intonation is a bit off.
I've generated a bunch of samples for comparison here: https://gitlab.com/danhawkes/piper-tts-test
