Yeah, whisper is pretty good out of the box in my experience, but the vast majority of the time I’m using it in my car. So the conditions aren’t ideal, or are out of distribution for Whisper. However CarPlay is detectable and common enough from what I’ve heard.

Second, even if the transcription is correct, it cuts me off at inappropriate times. It’s hard to talk naturally without pauses.
