From the article:

The researchers gathered training data by pressing 36 keys on a modern MacBook Pro 25 times each and recording the sound produced by each press.

In their experiments, the researchers used the same laptop, whose keyboard has been used in all Apple laptops for the past two years, an iPhone 13 mini placed 17cm away from the target, and Zoom.

Now they should do this under real usage and see if they get anywhere close to 95% accuracy. Phones are usually in pockets, people listen to music, not everyone has a MacBook.

I think it will be difficult for the average person to use this attack effectively, but I think this will become some sort of government spy thing for sure.
