Recent development in acoustic attacks and method to mitigate...

Per Bleeping Computer : New acoustic attack steals data from keystrokes with 95% accuracy 

"When Zoom was used for training the sound classification algorithm, the prediction accuracy dropped to 93%, which is still dangerously high, and a record for that medium."

For security's sake, think about adding a "Push to Talk" option to the Microphone audio settings?

Other than that, user awareness: adjust background noise suppression to the most aggressive setting, mute self when typing, etc..
