An Accurate and Rapidly Calibrating Speech Neuroprosthesis
N. S. Card, M. Wairagkar, et al.
An intracortical speech neuroprosthesis enabled a man with ALS and severe dysarthria to produce rapid, accurate conversational text and personalized synthesized speech after brief training—reaching 99.6% accuracy on day 1 and sustaining ~97.5% accuracy over 8.4 months at about 32 words per minute.
