Demonstration
A Brain Implant Restores Text, Voice and Facial Expression
A system decoded attempted speech at nearly 80 words per minute and animated a digital avatar with synthesized voice and facial movements.
The demonstration expanded the goal from transmitting words to restoring the social signals carried by voice and facial expression. Accuracy was not perfect, the participant remained connected to research hardware, and clinical usefulness would require reliable operation across time and settings.
