i wonder why this works.
Because all keys on a keyboard sound slightly different, computers can detect those differences, and compare it with a baseline from either the same keyboard or a model just like it.
Try this: on any keyboard (a membrane keyboard especially if you have one) try quickly tapping one key 3 times and then another key 3 times. Move around the keyboard or alternate between two letters.
Can you hear that they make different sounds, but typing the same letter has roughly the same sound? The" plok" has a higher or lower pitch (frequency is the scientific word for it), and a trained AI can match that pitch to a letter if it has or can get an idea of what corresponds to what.
