The new system being developed demonstrates that it is possible to create a synthesised version of a person's voice that can be controlled by the activity of their brain's speech centers.
The researchers explained how the human brain's speech centers choreograph the movements of the lips, jaw, tongue, and other vocal tract components to produce fluent speech.
We reasoned that if these speech centers in the brain are encoding movements rather than sounds, we should try to do the same in decoding those signals," said speech scientist Anumanchipalli said.
Scientists at the University of California, San Francisco, implanted electrodes into the brains of volunteers and decoded signals in cerebral speech centers
to guide a computer-simulated version of their vocal tract -- lips, jaw, tongue and larynx -- to generate speech through a synthesizer.
THE TOPIC: Marsh is a pioneer of brain surgery under local anesthesia, which allows patients to talk with the surgeon in order to avoid speech centers
. Here he condenses decades of specialist neurosurgery experience into gripping stories of what goes wrong in the brain.
"I think the only down side is we'll have to sit in the front row and look like we're paying attention," quipped Huntsberger, whose speech centers
on the impact of the 9/11 terrorist attacks, which occurred just days into the class of 2005's freshman year.
Such a task is made difficult by the fact that the speech centers
of the brain are separate from the areas of the brain that process images and sound.
Professional help is provided through hearing and speech centers, public and private schools, universities, hospitals, home health services, rehabilitation centers, private practices, nursing homes and preschool programs or classes.
Eugene Mayor Jim Torrey recently declared May as Better Hearing and Speech Month at the Eugene Hearing & Speech Center.
Mayor Torrey is the honorary chair of this year's Eugene Hearing and Speech Center's preschool campaign to help the children in our area receive services they need.
