- What it is
- A University of California study of a woman with severe paralysis whose brain signals were decoded into text, synthesized speech and a facial avatar.
- How much weight it carries
- Peer-reviewed in a leading journal. One participant and an implanted device, so the speed is a research result.
Facts taken from this source
- A second brain-computer interface study decoded attempted silent speech into text at a median of 78 words per minute with a median word error rate of 25 percent.
“we demonstrate accurate and rapid large-vocabulary decoding with a median rate of 78 words per minute and median word error rate of 25%” (Abstract)
