You can use a KOReader plugin, https://github.com/stradichenko/audiobook.koplugin, which has work-in-progress support for Media Overlays (the EPUB spec that Storyteller uses for readaloud)!

Wow I didn't even think about just using on device AI.

I'm going to set this one up and try it with kokoro which has the most natural for small size that I've seen. Wonder if the paperwhite 12th Gen can handle it.

And also setup the main repo for when I have the real audio book. Thanks!

I tried running Kokoro on my iPhone XS (several years old), and it was slower than real-time. So, i wouldn’t expect it to be usable on a Kindle. But if you find a solution, please let me know.

		Kokoro can be hacked a bit (see script https://github.com/DavidVentura/translator-rs/blob/master/sc... ) which makes it about 3x faster. My phone went from slightly slower than realtime to very comfortable (also lower latency on first utterance!)
