Scientists have created a brain-computer interface device that can translate thoughts about speech into spoken words in real time. This experimental device aims to give voice to individuals who are unable to speak, such as those with quadriplegia. In a recent study, the device was tested on a 47-year-old woman who had been unable to speak for 18 years due to a stroke. The device was implanted in her brain during surgery as part of a clinical trial. What sets this device apart from other brain-computer interfaces for speech is its ability to translate intent to speak into fluent sentences without the delays typically seen in other systems. The device works by recording the woman’s brain activity using electrodes while she silently speaks sentences in her brain. An AI model then translates this neural activity into units of sound, creating a synthesized speech sound that the woman would have spoken before her injury.
This innovative approach allows for a streaming method of speech decoding, processing each chunk of speech in real time, allowing it to keep up with the natural pace of conversation. While more research is needed before the technology is ready for wide use, the potential for this device to assist individuals with speech disabilities is promising. With sustained investments, the researchers believe that this technology could be available to patients within the next decade.
