Whether that's due to my slight autism or massive nerdery, I don't want more realistic voice. I already switched to non-advanced voice in gpt, and I cannot imagine wanting the mmmhms, the yesses, the laughs, in my ai interaction. I want to ask a structured question and get a structured meaningful response. Informative and structured are really the KPIs. The umms and ahms of existing gpt advanced voice are annoying enough, the recent increased usage of first person almost a deal breaker (when asking for bike technique on lose surfaces yesterday, it literally gave me "back when I was learning bikes riding" story - eww).
Fascinating to see the architectural advances though, even when they deliver something I personally don't need :)
