"Researchers at the University of Cambridge have developed Revoice, a wearable smart necklace that helps patients who suffered from stroke speak naturally again. The device was created to help the patients communicate in a more natural way without surgery or brain implants in hopes of bringing their old voices back. It is a soft, flexible wearable device that looks like a fabric choker worn around the neck."
"The wearable smart necklace Revoice aims to turn silent or unclear speech movements into clear, full sentences that other people can understand, working in real time, so users can take part in conversations. Revoice uses ultra-sensitive sensors to collect signals from the body. First, they pick up tiny vibrations from the throat muscles when a person mouths words, even if no sound comes out. Second, they measure the person's heart rate, which can give clues about their emotional state, such as stress or frustration."
Revoice is a soft, flexible wearable fabric choker designed for stroke patients to restore natural speech without surgery or brain implants. Lightweight, comfortable, and washable, the necklace minimizes medical stigma through modest design. Ultra-sensitive sensors detect tiny throat vibrations when a user mouths words and record heart rate to infer emotional states like stress. Two AI agents process the signals: one reconstructs words from silent throat movements, and the other interprets emotion and context using heart rate and situational cues. The system converts short or unclear speech movements into full, emotionally appropriate sentences in real time to enable conversational participation.
