The device was developed by researchers from the University of California，San Francisco．Their results were recently published in a study in the journal Nature．Scientists created a "brain machine connection" that was set in the brain．The device was built to read and record brain signals that helped control the muscles to produce speech．These include the lips，tongue and jaw．
The study involved five volunteer patients who were being treated for epilepsy （癲癇）．The individuals had the ability speak and already had electrodes （電極） set in their brains．The volunteers were asked to read several hundred sentences aloud while the researchers recorded their brain activity．
The researchers used audio recordings to reproduce the vocal （發(fā)聲的） muscle movement which is the key to producing human speech．Future studies will test the technology on people who are unable to speak．
The study reports the reproduced sentences were understandable to hundreds of human listeners asked to write out what they heard．The listeners were able to write out 43 percent of sentences with perfect accuracy．
Edward Chang is a professor of the university's Well Institute．He was a lead researcher on the project．Chang admitted that much more research of the system would be needed to reach the goal of perfectly reproducing spoken language．
