"Visual microphone" can decode words from the vibrations in an object.
A MIT student has shown how the tiny vibrations caused by sound waves can be picked up by a high speed video camera, and decoded with software to figure out what sounds were being made.
The technique allows the researchers find out the subject of a conversation, for example, by watching the vibrations in a glass of water or a bag of chips.
