I would really love to see you get funding for developing an open platform for TTS that can offer commercial options that fuel growth. I really want to see your work scale. Easy TTS from custom data needs to be a thing.
Good job with the stuff you've built, and good luck!
I remember giving Mozilla TTS a try but the docker image would crash on punctuations and symbols. Seemed to require clean up of the text and submitting it in small chunks.
Hope I am not repeating any comments here. My suggestion is that you start recording as soon as possible and as much as possible without worrying about technicalities. You can also use if you have any old voice records or videos with a relatively good voice quality. For now maybe she can read a book aloud in a silent room. After you have the data I can also help if you like to create a TTS model.
It is a single html file, no server and does everything I need.
Maybe it’d be useful for you as well… Kudos…
