@nolan I'm not sure what you mean by speech to text. You ask it voice commands and it answers you in voice, though I believe it also saves a history of your AI interactions in the app so you can look at them later. I haven't needed to do that though.
The sound quality is okay, I like it better than the Bose Frames I used to have, but it is not a replacement for headphones. It is good enough that you might not care just walking around though.
