I'd love to have something similar that's lightweight and not serverside node.js
please revisit it if you can.
Check out https://github.com/aedocw/epub2tts for creating an audiobook from epub. Take a look in the utils directory for notes about fine-tuning a voice clone. I can tell you I've done some voices that are close enough to the original to be pretty shocking.
Feel free to get in touch if you have any questions, it's pretty fun making your own audiobooks with the reader of your choice!
By the way, I would love a service where I could listen to HN. Play the first title and then wait for me to hit the space bar to play the next. Highlight the one I just heard, so when I'm interested int a submission, I have it right in front of me.
It's a really good book, I wish more people were aware of it and read it.
