That's actually quite a good job, I wonder if it could be improved by playing with the reverb a bit. I think I prefer it to the AI generated version because there is that emotion though.
These AI generated ones are using a new model by eleven labs https://beta.elevenlabs.io/ If you can get a clear MP3 of a character talking for as long as possible, keeping it under 10mb you can create a voice model for them, then generate voice lines based on it.
In theory, you could do this for any Kotor Companion; though as I've said it lacks something in terms of emotional inflection so it's going to work better on lines meant to be delivered in a plain way.
