Yet another retort addressed directly in the post:

> Raw audio playback: Very helpful if STT doesn’t work perfectly due to wind or loud background noises

Yes I know but I doubt it will capture much at all when there's significant wind noise, even enough to understand by ear without STT.

A friend of mine has her phone on her handlebars in a gps mount and she sends me voice messages through her bluetooth headset and those are hardly intelligible. A hand on the handlebar would be even further from the mouth.

And those are pretty good ones with multiple microphones.
