Decoding Keystrokes: High Accuracy Typing Inference from Sound | October 03 2024, 14:22

11 years ago, I wondered if it was possible to tell by the sound of keystrokes whether someone was messaging in a messenger or not. In 2023, a scientific article is published with a prototype that can determine with 95% accuracy what a person is typing just by recording the keystrokes on a smartphone, and 93% accuracy when recorded through Zoom. The code in the article is declared to be available to other researchers. And they admit that they have not yet used language models, but with them, it should be really good. Link in the comments.
