to make thoughts literally


The researcher has the path of a decoder that converts brain signals into words. Then, it can be used by stroke or paralyzed patients.

If they can not talk about stroke or paralysis because they can not talk, they use a decoder that they can use to make the brain signals become a speech? words ? According to a study published on Wednesday, the researchers are a follow-up.

They invented the playback decoder computer-based synthetic words, from the brain signals that cause the corresponding movements in the mouth. Presented in the journal natureThis technique is still in childhood and its setting is not tomorrow. However, this expects patients to know how to talk in some days and have lost their lives ability.

" Our goal is to create a recovery technique for the recovery of patients unable to talk, such as cancer or cancer, for neurological diseases. One of the test authors, Edward Chang, at the University of California, San Francisco, told AFP.

By means of eye or mind movements, the device can already help these patients to complete the letter letter. While improving the quality of life, these systems are slow, maximum 10-minute production per minute for 150 conversations. The idea of ​​the researchers was to go straight to the words: brain.

Synthetic voice results are amazing

The experiment was treated with five friends epilepsy. Within this treatment, the electrodes that were placed in the brains of brain were asked to read predefined sentences. The goal was to identify with electrodes. It's the brain responsibility articulate words Then they decoded these signals, linking the necessary movements, pronunciation, sounds, tongue, lips or larynx. In the end, according to these movements, these sentences were reproduced on a computer. All sentences in English, these sentences have simple construction, for example: " You can not find the proof book you are looking for ".

The audio files that scientists have published are surprising: of course, synthetic "speechless" words, but others are clearly understood as much as in the natural version of the lessons learned. " Brain Signs Related to brain movements speech partially all people have common, says Edward Changek. One day it will be possible to establish a decoder that does not speak to a patient talking to a speaker, who is able to control himself. ".

It is surprising that when the researchers asked mumble words for the participants, they did not say it, when they play a song. Of course, the results were less than actual phrases, however, scientists believe that they can synthesize computer-word words.
