Scientists have developed a brain-computer interface (BCI) device that can translate thoughts about speech into spoken words in real time. The device was tested on a woman with quadriplegia who couldn’t speak for 18 years after a stroke, allowing her to convert her intent to speak into fluent sentences. Unlike other BCIs for speech, this device has minimal delay, making it more natural and seamless for communication.
The device works by recording the woman’s brain activity while she silently speaks sentences in her brain, using a synthesizer to create a speech sound based on her pre-injury voice. The signals are then translated into units of sound using an AI model, creating a streaming approach that processes speech on the fly. This quick decoding has the potential to keep up with the fast pace of natural speech and improve the naturalness of spoken language.
While more research is needed before the technology is widely available, the researchers believe with sustained investments, it could be ready for patients within a decade. The study represents a significant advance in the field, with potential implications for giving a voice to those unable to speak due to various conditions. The researchers hope that this groundbreaking technology can help improve communication and quality of life for individuals with speech impairments.
