This is great.. one question though, how do you circumvent privacy perspective/law.. although I do understand that, its owners is generally on the user, but do you have some indication for the world that recording is on.. good wishes for your success..
the vibration sensor for phone calls is the clever bit, most external recorders only ever catch your side of the call. is that reading bone conduction off the phone body or picking up the speaker directly
offline-first is the interesting call here, most voice hardware punts to "always connected" and eats the latency. curious how you're handling the accuracy tradeoff on-device before the sync-and-transcribe step kicks in, especially with 4 mics picking up crosstalk in a real meeting room
Very interesting. Does it automatically capture, or do you have to record every time? I think it's great for capturing ideas. I have carpal tunnel syndrome, and anything I can voice-to-text is helpful.
How much is the hardware?
