Biomedical researchers reported in Nature that they’ve made a breakthrough in the quest to restore speech to those who lose it due to injury or illness.
Using implanted electrodes, the system was able to recognize and decode brain waves accurately enough to produce 150 spoken words per minute, about the same pace as natural speech. Previous efforts were plodding by comparison, producing only a few words per second.
If you’re wondering how Stephen Hawking did it: He was actually typing, using a cheek muscle, The New York Times reported. So the new system is an entirely different approach.
