Gyrophone: Recognizing Speech from Gyroscope Signals (2014) [video]

Where can we hear what it sounds like?

They don't explain anything in that link.

There's a second video on that page as well that explains the technique used.

Mods, consider adding (2014) to the title as this was presented at USENIX '14.

Thanks! We've updated the title.

Oh my, this is huge!
