Imagine you’re paralyzed and can’t move or speak. How would you communicate with the world? This video describes the principles of early braincomputer 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.
