University of Columbia Researchers Translate Brain Signals Directly Into Speech Published on February 01, 2019 at 12:30PM dryriver writes: There is good news for people who have limited or no ability to speak, due to having suffered a stroke for example. Researchers at Columbia University have managed to turn brain signals in the auditory cortex of test subjects into somewhat intelligible speech using a vocoder-like system with audio output cleaned up by neural networks. The findings have been published in the journal Nature. Here's an excerpt from the Zuckerman Institute's press release, which contains example audio of a number sequence being turned into robotic speech: "In a scientific first, Columbia neuroengineers have created a system that translates thought into intelligible, recognizable speech. By monitoring someone's brain activity, the technology can reconstruct the words a person hears with unprecedented clarity. This breakthrough, which harnesses the powe
