can I choose any voice? would love to read software engineering books in voice of Morgan Freeman, or maybe even better, Scarlett Johansson

The demo video doesn't seem to have any audio in it! At least none that either ffmpeg or whatever Firefox uses can recognize.

I've been using Kokoro TTS with the CLI app, audiblez, mentioned in the "Similar Projects" section of the README. The model is fast and delivers impressive quality for its small size. Some issues I have faced, however, are: a) It doesn't distinguish periods at the end of sentences from the dots in abbreviations such as "Mr." or "Mrs." The result is an awkward pause between "Mr." and the name. b) It doesn't handle ellipses well. c) Words are pronounced the same way regardless of context.

Does it turn it into spoken word or an audiobook? Because good audiobooks often have voice actors that read the characters with different emphasis and dialects. I imagine tools like chatgpt could do this for a few sentences but what about an 8-20 hour audiobook?

I think there are still basic hurdles to take before we can go epub to audiobook in a quality that can compete with current state of the art.

Or am I missing something?

I tried Kokoro for voicing blog posts and articles and wasn't impressed to be honest. Right now Gemini 2.5 Flash TTS is a much more capable system with generous free limits (about 10 minutes per generation and about 90 minutes per day). Voices are not very consistent between generations, but for shorter pieces it's not a big deal (but will obviously be for books)
