Interesting, I read epubs on Android using aiTTS as TTS engine using Google cloud voices.

What I would really like is an option to download the whole book as mp3 for offline playback, and different voices for each character.

Moon+ Reader has offline playback although the voices aren't as good, but on the bright side, if someone makes a local AI text-to-speech engine, then that can plug into the app and it'll work fully offline.

Nice, well you can download each audio file you convert to your device at any time.

I found a single file didn't make sense as you lose your place in it easily.

Instead splitting each chapter into a file seemed to do well.

But, you really do want a listening app. Otherwise it get harder to share and listen to on your phone.

So far I created a listening app as a PWA for the time being.

I use an audiobook app (Voice audiobook player on Android) which holds my place in line for even large single-file books.
