I'm using https://github.com/rhasspy/piper mostly to create some audiobooks and read some posts/news, but the voices available are not always comfortable to listen to.
Do you guys have any recommendation for a voice changer to process these audio files?
Preferably it'll have a CLI so I can include it in my pipeline to process RSS feeds, but I don't mind having to work through an UI.
Bonus points if it can process the audio streams.
I don't want to manage piper voices, I can handle that directly in my file system as I only have a few.
The issue is none of the ones I've found are good for me, so what I need is something to change the voice once it has been generated by piper.
