Holy shit, accuracy drops to 93% only when done by Zoom call. That's very impressive. Privacy truly is dead.

Looks like I won't be getting a mechanical keyboard after all.

Holy shit this is so damn impressive, stealing keyboard clicks with audio, a audio based keylogger. Scary.

Looks like the next trend for keyboards is silent keyboards.

Given that there's variance among even the same key switches, as well as differences in sound based on the construction of the keyboard the switches are placed in, possibly even based on the surface the keyboard is placed on, the model would probably have to be trained specifically for a given target.

Since I'm working from home, I have much bigger things to worry about if attackers get access to my physical machine to train their model lol
