I like the spoken word conversation, but it sounds too human (and a bit boring). I think that, counterintuitively, it should sound more artificial.
This would make it less "uncanny valley" and also likely reduce AI psychosis, as it would lessen the illusion that it was a real person in there.
And it would make ChatGPT a lot more fun! Imagine talking to Max Headroom or GladOS! (those would be my suggestions). I bet Matt Frewer and Ellen McLain would be up for it.
Think about it, you'd achieve two apparently opposite goals at once: The feature would both give your AI some personality while actually reducing the bad effects of your AI having, er... too much personality.
What do people think?
