Whenever we think to ourselves, rather curiously, the vocal chords get activated very slightly - faintly mirroring what would happen if we were to say the words out loud. This is known as subvocal speech and can be picked up by EMG sensors on the neck that pick up the tiny electrical signals generated by the weakly activated muscles. While the technology doesn't exist to turn these signals back into speech, it is possible to train the system to distinguish between a number of different general patterns which can trigger specific computer commands.
