The Neuralynx System translates thoughts into speech. It connects to the neurons, sending signals wirelessly to a laptop, which translates the brain activity into spoken English. It's not science fiction: They tried it with a paralyzed 26-year-old and it works.

According to the research paper, they inserted the electrodes into the patient's brain, installing signal amplifiers and transmitters under the scalp. The circuitry—powered by an induction electric supply—transmits the signals to a laptop via FM radio. The software then converts the analog signal to digital data that the neural decoder interprets these into speech commands, which are then sent to the synthesizer.

The whole process takes 50 milliseconds, which is the same amount of time it takes to any normal person to do the same process, using their nerves, vocal chords, and mouth. According to Neuralynx project leader Frank Guenther—from the Department of Cognitive and Neural Systems and the Sargent College of Health and Rehabilitation Sciences at Boston University—their system is going to get even better soon.
