I tried to select kokoro in the python module but it says in the logs that only coqui is available. I do have to say the coqui models sound really good, it's just the type of voice that puts me off.
The default prompt is also way too "girlfriendy" but that was easily fixed. But for the voice, I simply don't know what the other options are for this engine.
PS: Forgive my criticism of the default voice but I'm really impressed with the responsiveness of this. It really responds so fast. Thanks for making this!
