A brain-computer interface and AI have restored speech to Ann Johnson, nearly two decades after a brain stem stroke. Researchers at UCSF and UC Berkeley developed an AI-powered avatar that decodes her brain signals into words, enabling natural communication at 78 words per minute. This is a vast improvement over her previous 14-word-per-minute assistive technology. Using a recording of her wedding speech, the AI even recreated Ann’s unique voice. This breakthrough offers hope for millions with speech impairments, showcasing AI’s potential for accessible communication. Learn more about this life-changing research.
