You can switch back to the "Advanced" or "Standard" models by clicking on your user icon then settings, voice. There is now a drop-down list with: Live, Advanced, and Standard.
Each one is worse than the previous.
Basic:
* Good, monotone
Standard:
* Too much inflexion, uncanny.
* Knows how to pronounce foreign words in the correct accent. So you can use this to practice another language. It can fluently switch back and forth even within a sentence.
Live:
* Overly strong accents, like a young actor hamming it up.
* Doesn't get language accents right, so it is useless for language learning.
* Adds "Hmmm..." and "uh huh" and "Interesting..." as you speak. Sometimes it sounds like a Minecraft villager or Yoda thinking.
* Starts every response with boisterous exclamations and thinking sounds. "Ohhhh... Hmmm uhhhh, oh yeah that's (complex | interesting | fascinating)!"
(The text version does this too, but not nearly so hard and overdone)
I love how the technology advances, but I think OpenAI is overdoing it and the voices get cheesier and more annoying with each version. If a human being talked to me like this I would assume they are being an ass and making fun of me. Or maybe they were high?
