What is the Revoice device for stroke survivors?

Revoice is a wearable device developed by University of Cambridge scientists that helps people with post-stroke speech impairment communicate naturally again by translating silent mouthed words into fluent speech using AI.

How does the Revoice wearable work?

The Revoice device uses ultra-sensitive textile strain sensors to detect subtle vibrations in the throat from silently mouthed words and measures pulse signals to estimate emotional state, which are then processed by AI agents to generate fluent speech.

What were the results of the Revoice trials with stroke patients?

In trials with five stroke patients, Revoice led to a 55% increase in satisfaction and improved their ability to communicate fluently.

AI Wearable Restores Speech After Stroke

Scientists at the University of Cambridge have developed a novel wearable device called Revoice, designed to assist individuals who have lost the ability to speak clearly following a stroke. This innovative technology aims to restore natural communication without the need for surgery or brain implants.

The device, resembling a soft choker, is equipped with sensitive textile strain sensors and a wireless circuit board. It detects minute vibrations in the throat as the user silently mouths words. Simultaneously, it monitors pulse signals to gauge emotional state, processing this data through two artificial intelligence agents.

Unlike previous silent speech systems, Revoice avoids significant delays, offering near-instantaneous responses. Its efficient AI-driven throat sensor system and lightweight language model ensure low power consumption, with a battery expected to last a full day. In trials with five stroke patients suffering from dysarthria, participants reported a remarkable 55% increase in communication satisfaction.

Researchers believe Revoice could also benefit individuals with Parkinson's disease and motor neuron disease. The comfort and washability of the device make it suitable for daily wear. Larger clinical trials are planned to expand language support and emotional expression capabilities, with findings published in Nature Communications.
