In July 2021, they announced the results: Pancho became the first person with vocal paralysis to successfully generate words by controlling a speech neuroprosthesis with his brain.
What makes this technology so powerful is that it combines new knowledge about the neuroscience of speech with a form of artificial intelligence called machine learning. Machine-learning algorithms enable researchers to teach computers to recognize complex and sometimes subtle patterns in data that humans are unable to see. These algorithms have proven hugely successful at tasks such as image classification, language translation, and speech recognition (think Siri on your iPhone). Now scientists like those on Chang's team are using machine learning to augment impaired brains, blurring the boundary between the natural and artificial.
