Neuroingenieros in the US can convert brain signals into speech



Neuroscientists at the University of Columbia in New York have created a system that transforms ideas into understandable and recognizable discourse that could mean new ways of communicating computers directly with the brain, according to research known as this. Wednesday

Al to monitor the activity of the brain somebody technology can recreate the words that a person can hear with unprecedented clarity.

This one in advance, which benefits power synthesizers and artificial intelligence, provides the basis for people who can not speak, for example those living with amyotrophic lateral sclerosis (ELA). or recover from stroke, regain the ability to communicate with the outside world.

"Our voice helps us to connect with our friends, family and the world around us, so the loss of voice due to injury or illness is so devastating, "said Nima Mesgarani, chief investigator of the Brainstorm Institute, Dr. Mortimer B. Zuckerman of Columbia University.

The expert thought he had proven, "With the right technology, the ideas of these people can be deciphered and understood by any other listener."

Decades of research have shown that cWhen people speak and even imagine they are talking, light patterns of activity appear in the brain. AND A different signal pattern also appears when we hear someone talking or imagine that we are listening.

The team of investigators resorted to "Vokoder"A computer algorithm that can synthesize words after receiving training in the recordings of people who speak." This is the same technology used by Apple's Amazon Echo and Siri, which provides verbal answers to our questions, "Mesgarani explained.

To to teach "vocoder" to interpret brain activity, Mesgarani has teamed up with Ashesh Dinesh Mehtem, neurosurgeon at the Northwell Health Physicians Partners Neuroscience Institute, which treats patients with epilepsy, some of whom need to undergo regular brain surgery.

"When working with Dr. Mehtem, we have asked epileptic patients who have already undergone a brain surgery to listen to phrases that have been told by different people to measure brain activity samples," said Mesgarani, who noted that these neural patterns trained as "vocoder"

Team later you plan to try out the most complex words and phrases and even try to make your system part of the implant as with some patients with epilepsy that translate the ideas of the user directly into words.

"It would give someone who has lost the ability to talk, whether because of an injury or illness, a new opportunity to connect with the world," he added.
