Wearable Revoice Restores Natural Communication After Stroke

Researchers at the University of Cambridge have developed Revoice, a wearable choker that decodes throat vibrations and heart-rate signals with AI to reconstruct speech, reported in Nature Communications (Tang et al., 2026). In a small trial with five dysarthria patients and ten healthy controls, the system achieved a 4.2% word error rate and 2.9% sentence error rate, and a larger clinical study is planned this year.
