Thinking about it, Google captua algorithm needs to be able to detect these patterns also. Otherwise AT users would be complaining that they always get visual or audio captures while AT users will automatically be verified.

I can't go into details but I'd say that when a screen reader is active there are clues related to events and interactions, etc. that can accurately predict this. Similarly when only the keyboard is used or when speech recognition is used there are certain patterns of events and interactions that provide clues. For high contrast and zoom there are similar clues when you insert content and you see the aspects of that content changed by the user's browser settings.
