My wife will be undergoing significant oral surgery in a few weeks and there is a SMALL chance she may lose the ability to speak. I’d like to prepare, just in case, to have technology to reproduce her voice from keyboard or other input.
My ideal would be an open source “deepfake toolkit” that allows me to provide pre-recorded samples of her speech and then TTS in her voice. Unfortunately most articles and tools I’m finding are anti-deepfake. Any recommendations?

Fallback would be recording her speaking “phonetic pangrams” and then using her pre-recorded phonemes to recreate speech that sounds like her. I feel like the deepfake toolkit is the way to go. Appreciate any recommendations… There must be open source tools for this??
