The researchers placed electrodes on the surface of the linguistic area of ​​the awake patient's brain, using these electrodes to monitor the patient's electrical response pattern when listening to the recording. Then they built a computer model that allowed the played voice to match those electrical signals.
Scientists are working on a machine that can "translate" human thinking into speech, which will soon become a reality. This research has been carried out for several years, and recently it has finally made a breakthrough. It can monitor the brain activity of the subject and play back a word that the subject just thought.
Although there is still a long way to go, scientists believe that the machine can help stroke patients or other people who can't speak to communicate with people they love.
Professor Robert Knight of the University of California at Berkeley and his team have been studying how overlapping areas of the brain work when listening to words, words, and words. "The challenge we are currently facing is how to turn brain activity records into statements that can be understood when people think about the words they are going to say in their minds," Knight said.
According to Knight, the goal of the device is to help people with motor neuron diseases such as sputum or amyotrophic lateral sclerosis. "There are many neuronal diseases that limit the ability of patients to speak. Although they know what they are saying, they can't say it." Knight said, "We hope to develop an implantable device that can break the way we want to talk." The brain signal and convert it into an audio file to play."
