While it works imperfectly, but in most cases the result is understandable.
Researchers at the University of California created an implant that connects to the brain and translates thought into speech. The device can simplify the life of paralyzed and dumb people.
The implant does not read the thoughts themselves, but the intentions of the person to speak: the device processes only signals from the brain associated with the movement of the lips, tongue and mouth. After that, the computer calculates how these impulses would form to speech, if a person could speak and give a synthesized voice.
As the scientists themselves, while technology is far from ideal. The results are most often obtained crumpled and can be disassembled only in 70% of cases, but before that the researchers could not generate whole phrases in this way.
