Scientists have developed a brain implant that can decode inner speech into text or sound with up to 74% accuracy, offering promising advancements for individuals with speech or motor impairments, though further improvements and safeguards are needed.
Researchers at the University of California have successfully implanted electrode implants into the brain of a stroke victim, enabling her to regain her ability to speak after 18 years. Using artificial intelligence, the team trained an algorithm to detect her brain signals and translate them into sentences, creating an avatar with a voice personalized to her pre-stroke sound. Despite some errors in word selection, the breakthrough offers hope for rehabilitation and highlights the potential of AI in healthcare.
A paralyzed woman who hadn't spoken for years after a stroke has regained the ability to communicate through AI implants. The procedure involved implanting electrodes in her brain, which intercepted her brain signals and generated a digital avatar that "speaks" her thoughts using a recorded copy of her voice. The avatar also uses facial expressions, making it more lifelike. This is the first time speech and facial expressions have been synthesized from brain signals. The AI system recognizes phonemes and decodes the brain signals into complete words at a rate of about 80 words per minute. The team is working on a wireless version, aiming to create a system that enables speech from brain signals in the future.
