Paralysis Patients Can Communicate at Conversational Speeds with Brain-Computer Interface
๐งต The TL;DR
A new pre-print has released demonstrating a BCI that can turn speech-related neural activity into text, allowing those with paralysis to communicate at 62 words per minute. This was made possible by microelectrode arrays that recorded single neuron resolution with a 9.1% word error rate on a 50 word vocabulary and a 23.8% word error rate on a 125,000 word vocabulary. Higher channel count devices and further algorithmic improvements could open up a feasible path for restoring communication to those with paralysis.
