An advanced brain-computer interface (BCI) that can translate brain signals into speech with up to 97% accuracy, has restored the speech of a man with amyotrophic lateral sclerosis (ALS).

“Previous speech BCI systems had frequent word errors. This made it difficult for the user to be understood consistently and was a barrier to communication. Our paper demonstrates the most accurate speech neuroprosthesis ever reported,” study investigator David Brandman, MD, PhD, co–principal investigator and co-director of the University of California (UC) Davis Neuroprosthetics Lab, said in a news release.

The system has allowed a man with severely impaired speech due to amyotrophic lateral sclerosis (ALS) communicate with friends, family and caregivers.

The technology has been “life-changing” for the patient....
