- Stephen Hawking communicated using a sensor in his glasses that detected cheek muscle movements to select characters, synthesized into speech by a DECtalk TC01.
- Recent brain-computer-interface (BCI) devices translate neural activity into text and speech but had latency and limited vocabulary issues.
- A UC Davis team developed a neural prosthesis translating brain signals into phonemes and words, aiming for a fully digital vocal tract.
- The goal is a flexible speech neuroprosthesis allowing paralyzed patients to speak fluently, control cadence, and modulate intonation.
- Previous neural prostheses converted brain signals to text with a 25% error rate, insufficient for daily communication.
