Hi Jeff, Thanks for updating the TTS endpoint! I was literally about to have to make a workaround with the chat completions endpoint with a hit and hope the transcription matches strategy... as it was the only way to get the updated voice models.

Curious.. is gpt-4o-mini-tts the equivilant of what is/was gpt-4o-mini-audio-preview for chat completions? Because in timing tests it takes around 2 seconds to return a short phrase which seems more equivilant to gpt-4o-audio-preview.. the later was much better for the hit and hope strat as it didn't ad lib!

Also I notice you can add accents to instructions and it does a reasonable job. But are there any plans to bring out localized voice models?

It's a slightly better model for TTS. With extra training focusing on reading the script exactly as written.

e.g. the audio-preview model when given instruction to speak "What is the capital of Italy" would often speak "Rome". This model should be much better in that regard

= No plans to have localized voice models, but we do want to bring expand the menu of voices with voices that are best at different accents

Great to hear thanks. My favorite was "I would like you to repeat the following in an Australian accent: Hi there, welcome to Sydney." which was more often than not swapping "Hi there" for "G'day"!
