Researchers develop a brain-computer interface that can translate thoughts into audible speech almost instantly, potentially revolutionizing communication for people with severe paralysis.

Researchers from the University of California, Berkeley and the University of California, San Francisco have achieved a significant breakthrough in brain-computer interface (BCI) technology. They have developed a system that can translate neural signals from the brain of a person with paralysis into audible speech in near real-time
1
.The system uses a brain implant with 253 electrodes placed on the surface of the brain cortex, specifically in the area responsible for speech motor control. This implant, known as a high-density electrocorticography (ECoG) array, can record the combined activity of thousands of neurons simultaneously
2
.The breakthrough relies heavily on artificial intelligence algorithms. These algorithms decode the neural signals and transform them into spoken sentences using a synthetic voice. The system is personalized to sound like the patient's own voice before their injury, trained on recordings from old videos
1
.Unlike previous efforts that could only produce sounds after users finished an entire sentence, this approach can detect words and convert them into speech within three seconds. The system samples brain signals every 80 milliseconds, starting 500 milliseconds before the patient begins to silently say the sentences

.The study's participant, identified as Ann, lost her ability to speak after a stroke in 2005. During the trial, Ann silently mouthed 100 sentences from a set of 1,024 words and 50 phrases that appeared on a screen. The BCI device captured her neural signals and produced between 47 and 90 words per minute
