However, this technique worked only for coiled cables, exposed at the surface, at distances of up to 5 meters from the speaker. Burying the cable under just 20 centimeters of dirt was enough to muddy the speech. And straight cables—even exposed ones right next to the speaker—did not record speech well.

Kind of important to mention that.

Sounds like the whole mobile phones can tell what you are typing because of the vibrations from the keyboard being picked up by the gyroscope. Then you read the research and it was only about 70% right on a known piece of text and like 40% on unknown text.
