The Illusion of Speech
Your brain is an extremely complex pattern-recognition machine. Neuroscientist Jamshed Bharucha demonstrates to our audience how three indistinct synthesized sounds can be superimposed to create the illusion of human speech. Our brain is able make inferences from the most prominent energy peaks in a simple phrase and recognize the words being spoken even if most of the information is stripped away.
