Yes - but you don't even need their output. I did this a dozen or so years ago at a coworking space, where I trained it on my officemate's keyboard assuming they were typing Ruby code, and then was able to guess their passphrase pretty quickly using the trained model.

I manually fudged spacebars and enters because they're accoustically obvious, and played around with punctuation keys. Generally the timing for fingers to move from one key to the other was where I was finding the strongest signal.

That must be a fun way to type in someone's password to their computer when they lock it and walk away to get some coffee...

I doubt the audio fidelity over a video call would be high enough to do this same thing, though. Esp. since all of those services have noise reduction stuff in place by default.
