The exceptional speech to text on the chatgpt iOS app is the main reason I use it. It’s so good. (I mean when you hit the microphone button in the bottom right, not the headphones / back and forth voice chat. Ie STT but no TTS.)

I’m assuming it uses whisper v3 plus gpt for post processing the whisper transcript.

I hope that with iOS 18 siri’s transcription is as good.

ChatGPT’s transcription is good enough that I can trust that even for a long 2 minute input, it’ll be 99-100% right. Whereas Siri I can’t trust that even for a single sentence.

I'm frustrated with Gemini Advanced because of this. It's very good at interacting with calendar and stuff like a digital assistant IF you use text to talk to it. The speech to text is awful (and borderline dangerous).
