Neuralink has demonstrated its brain-computer interface technology, with a brain implant that converts thoughts into audible words for a patient with ALS, Kenneth Shock, who has the disease that gradually removes the ability to move and speak. The demonstration featured a video showing the implant capturing neural activity associated with speech and converting it into text, which was then voiced through a computer program. The system uses machine learning to map brain signals to phonemes, the smallest units of sound. The test is part of Neuralink's ongoing Voice clinical trial and remains experimental. There are still delays in processing and accuracy challenges, but the company aims to improve speed and precision.
