Researchers at Stanford University developed a groundbreaking brain-computer interface (BCI) that translates inner speech into words, bypassing the need for physical speech attempts. Unlike previous BCIs that relied on muscle movements, this new system decodes silent thoughts. To protect patient privacy, a unique 'mental privacy' safeguard was incorporated. The study involved four severely paralyzed participants with implanted microelectrode arrays. The BCI uses AI algorithms to convert neural signals from inner speech into spoken words, offering a new hope for communication for those with severe paralysis.
