I'm not blind but I wrote an EPUB to Text-To-Speech reader using Coqui (a really good AI TTS project). There are books I wanted to listen to while doing other things, and I couldn't find audio-book versions of them, so this worked out perfectly. It could be that I did not do enough searching, but I was surprised I didn't see anything out there that already worked this way.
