> OpenAI is speech-to-speech, there is no TTS in voice mode

Which results in the interesting situation where the transcript isn't what was said:

Q: Why do the voice transcripts sometimes not match the conversation I had?

A: Voice conversations are inherently multimodal, allowing for direct audio exchange between you and the model. As a result, when this audio is transcribed, the transcription might not always align perfectly with the original conversation.
