The device could improve the quality of life for people with severe paralysis who cannot speak by enabling more efficient and natural communication.Chang lab, UCSF, NEJM
A team of researchers, led by Dr. Edward F. Chang at the University of California, San Francisco, developed a “speech neuroprosthesis.” This device directly decodes brain activity into words and sentences in real time. NIH’s National Institute on Deafness and Other Communication Disorders is supporting the ongoing work. Results from the first participant appeared in theA 36-year-old man, identified as “Bravo-1,” had been severely paralyzed for 16 years due to a brain stem stroke.
The researchers used machine learning to recognize patterns in the brain activity and associate these with what word the user was trying to say. The researchers also applied a model that predicted the next word in a sequence based on English word-use patterns. This provided an “autocorrect” function like that used in texting and speech recognition software.
