Neurologists at the University of California,located in San Francisco, they developed an implant that decodes brain signals and transforms them into synthesized speech. Development can be the basis for the construction of neural speech prostheses.
Over time, this will give a chance for normal communication.those suffering from the effects of stroke or traumatic brain injury. As well as patients with neurodegenerative diseases: amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, etc. The development was commented by Edward Chang, an employee of the Weil Institute of Neurobiology, a professor of neurological surgery. According to him, for the first time you can receive whole oral phrases, based on the activity of the human brain. So, there is a very real chance of creating a device that is clinically working for people who have lost their speech.
The new implant is placed in the human brain, where it scans the signals. The data thus obtained is decoded and then transmitted to another device. It is this that translates synthetic speech.
According to Edward Chang, the accuracy of the comparisonAnatomy and sound allows engineers to make for each patient a completely realistic virtual voice. 2 machine learning algorithms helped them in this. One is used by the decoder, which transforms the signals of brain activity, which are produced during speech, into the movement of the voice virtual path. The second algorithm is used by a synthesizer that converts these movements into the synthetic voice of the patient.
When the development can be applied in medicine on a massive scale, is not reported.
