Star Trek computer voice model is something I have yet to encounter, and I've looked repeatedly :) It's not about a specific voice, it's the fact they managed to capture "I am a utility" perfectly in the voice. Our modern friends do not want to be thought of as a utility, but to engender trust and agency all of their own and that's a huge problem for me.
For many years, I've wanted ED-209 (robocop) voice from something like espeak or similar. Still can't find anything good.
Not for chat, just as a way to make notification messages that sound like ED-209.
I just tell them to talk like Jarvis. I tried the "cold logic" prompt but it turned them into a bunch of assholes.
I thought to try voice cloning with dots.tts ( https://huggingface.co/spaces/rednote-hilab/dots.tts ), the result is pretty good, but likely wouldn't be fast enough to use on a quasi-realtime basis:
