Stanford researchers have developed a speech brain-computer interface (BCI) they say can translate thoughts into text at a record-breaking speed — putting us closer to a future in which people who can’t talk can still easily communicate.
The challenge: “Anarthria” is a devastating condition in which a person can’t speak, despite being able to understand speech and knowing what they want to say. It’s usually caused by a brain injury, such as a stroke, or a neurological disorder, such as Parkinson’s disease or ALS.
Some people with anarthria write or use eye-tracking tech to communicate, but this “speech” is far slower than the average talking speed. People with anarthria due to total paralysis or locked-in syndrome can’t even move their eyes, though, leaving them with no way to communicate.
