According to the United States media, recently, the United States scientists invented a real-time translation brain signal technology, built into the brain's internal devices to wireless means to transfer the brain signals, external language synthesizer can receive signals from the brain in real time and translation language adult classes.
At present, based on the technology of the "brain machine interface" is already a bit atresia syndrome patients in the experiment was successful.
The "brain machine interface" model and language synthesis processes
According to the scientists, the use of this technology, "ideological change language" process only needs to 50 milliseconds, the amount of time that and nervous normal people use language to express their thoughts at the same response time.
The research results for the first time succeeded in proving that the human brain into wireless device, through the brain consciousness on external voice device with real-time control. For those who lost their nerve damage because of the control, the result will be a blessing to them.The study by the United States Boston University scientist Frank-ancient entre el leading implementation, Boston University, perception and neural systems, health and Rehabilitation Sciences, Harvard-MIT health sciences and Technology Department of scientists to participate in this study.
The study results will be published in the United States the public library of science? integrated magazine.Ancient entre el said, "our research suggests that ' the brain machine interface ' users can directly control language output, use the relatively slow typing process.
”Scientists will this technology is applied to a 26-year-old atresia syndrome patients who carry out experiments.
The patients in the 16-year-old had had a brain stem stroke, brain stem stroke caused this time patients with motor neuron damage. Motor neurons are primarily used to perform the acts and actions of the human body. Motor neuron damage means that patients may receive limb paralysis, muscle atrophy, and even paralysis and other serious problems. In addition to the eyes from top to bottom and movement, the patient has symptoms of systemic paralysis appeared. However, his consciousness is cool, this is the so-called "atresia syndrome", i.e. consciousness conscious, but cannot speak, not activities.Five years ago, scientists will one electrode placement in patients with brain internally, approximately in language-specific movement before the cortex and the motor cortex.
Since then, the growth of nerve starts gushing to the electrode. Three or four months later, neural process has had on the electrode signal. Three years later, researchers began to test the "brain machine interface", ready to synthesized speech products. Because the system is based on remote sensing technology, so you don't need wires or sensor connected to the patient's skin, it also eliminates the risk of infection.Electrode will expand and neural signal into a radio signal.
The patient's head with a two piece slice sliced slices, which played the role of signal receiving antenna. When the brain's radio signals sent out, the scalp of receiving antenna enables the timely receipt and will these signals are delivered to the electrophysiology recording system. Record system will signal to digital conversion and classification. Classification data is input to a neural signal decoder decodes in. Then, the decoded results are then entered into the language synthesizer. Finally, the language synthesizer to generate human language. At present, scientists just experiment with vowels. The average time of only 50 milliseconds.Despite the current research results is only a small part of the synthesis of the vowel, but researchers believe that along with the gradual improvement of the system, in the near future may achieve consistent voice products.
Ancient entre el said, "our current plan is to develop a new language synthesizer, synthesis of more coherent voice. ”
