3rd Place Winner - BCI Award 2022 - Spelling using a BCI in a person with severe anarthria

Speech is the most natural and efficient way to communicate and is a fundamental aspect of daily life. In the individuals that are unable to articulate speech, for example those that have survived a brainstem stroke but have developed severe anarthria, assistive BCI technologies can help them to communicate by attempting to speak, type, or handwrite intended messages 🧠 Sean L. Metzger and his colleagues at UCSF designed a sentence-spelling system to enable real-time BCI spelling using silent speech attempts. They recorded electrocorticography (ECoG) signals from a 128-channel high-density array implanted over the sensorimotor cortex of a brainstem stroke survivor with severe anarthria and quadriparesis while he silently attempted to spell out words and sentences using the NATO phonetic alphabet. 💯 This project was submitted for the BCI Award 2022 and won the 3rd place. 🏆 Sean L.
