For the roughly half of stroke survivors who lose not their thoughts but their ability to voice them, silence has long been the cruelest aftermath of survival. Researchers at Cambridge have answered that silence with Revoice — a wearable collar that listens to the body's faintest attempts at speech and, through artificial intelligence, restores them to full sentences in real time. It is not a cure, but a bridge: a way to remain a speaking, dignified person while the slower work of healing unfolds.

Cambridge's Revoice collar restores speech to stroke patients using AI and sensors
Approximately half of stroke patients develop dysarthria, causing severe communication difficulties and psychological frustration for patients, caregivers, and families during recovery periods lasting months to years.
