A new device developed by a research team at UC Berkeley is able to produce mechanical speech using only the thought of the word being produced from the subject. The researchers hope that this device will enable patients suffering from conditions that limit or prohibit spoken communication, such as the effects from a stroke or Lou Gehrig’s disease, to be able to communicate normally.

The researchers placed electrodes on the surface of the subjects’ brains in the region associated with language, then recorded the electrical patterns their brains produced when perceiving spoken speech. This information was then applied to a computer model that sorted out which patterns belonged to which sounds, creating maps of the subjects’ perceived speech patterns.
