Resolves YES if, from now until through July 14th, some portion of non-insider users are able to use the fancier voice mode (as opposed to the current text to speech system) that can, for example, talk faster or slower at will, or change the emotion and tone of the voice. That is, it roughly matches the GPT-4o demo. However, it will still resolve YES if there are additional restrictions on the voice mode, but it's still clearly the same system that was in the demo.

Resolves NO otherwise. Solely ugrades to the text to speech which are not the system that was in the demo will resolve as no. It must be called something with "4o" on the name, and must be available on the ChatGPT website or app, otherwise it resolves no.

Question idea from @Flowers, who had a similar question that ends today, June 24th.

I will let myself bet in this market because it's fairly unambiguous resolution criteria. If there is any unexpected ambiguity, the question will resolve to yes if 90% is hit and sustained above 89% for 3 days any time after July 25th, or to no if 10% is hit and sustained below 11% for 3 days any time after July 25th.
