Researchers Are Translating Brain Activity Into Speech

It could lead to a computer-generated speaking tool for the speech impaired

SScientists are getting closer to developing a computer-generated tool to allow people with severe speech impairments — like the late cosmologist Stephen Hawking — to communicate verbally.
