The smile of disbelief soon becomes a cry of emotion as 45-year-old Californian Casey Harrel hears his voice for the first time in four years when amyotrophic lateral sclerosis (ALS) began to affect the nerves that control the muscles in his throat. His wife, who is by his side with their daughter, is also overcome with emotion. The test has to stop for a few minutes, because some members of the team at the University of California, Davis, are also moved. The group has developed a brain-computer interface (BCI) that not only interprets what Harrel wants to say in real time but also picks up on his intonation and speaking style.
