Speech From Brain Signals

Imagine you’re paralyzed and can’t move or speak. How would you communicate with the world? This video describes the principles of early brain-computer interfaces (BCIs) designed to read electrical brain signals, analyze how brain activity patterns contribute to vocal tract movements, and reproduce the sound patterns as speech. The model is a first step toward one day restoring paralyzed individuals’ natural rate of communication and quality of life.
