AI-Powered Wearable Device Offers Hope for Speechless Individuals

Engineers at UCLA have introduced an innovative AI-powered wearable device designed to help those without a voice regain the ability to speak.

This cutting-edge technology has the potential to revolutionize communication methods for individuals affected by conditions such as laryngeal cancer surgeries or vocal cord dysfunctions.

The newly unveiled device, featured in Nature Communications, represents a miniature marvel, measuring just one inch square and positioned on the skin near the throat. Developed by Jun Chen and his team, this device utilizes bioelectric signals from the larynx muscles to generate speech with unparalleled precision, boasting an impressive accuracy rate of nearly 95%.

At the core of this revolutionary device lies a self-powered sensor and an actuator, seamlessly integrated within silicone and activated through magnetic layers. The sensor employs magnetoelastic technology to detect movements of the laryngeal muscles, translating them into electrical signals. These signals are then analyzed by a sophisticated machine-learning algorithm to produce coherent speech outputs, which are subsequently transformed into audible sound by the actuator.

Remarkably lightweight at just 7 grams and with a thickness of a mere 0.06 inches, the device is discreetly affixed to the throat using biocompatible tape, ensuring comfort and ease of wear. Its noninvasive nature and user-friendly design set it apart from more complex and invasive communication aids, making it an ideal solution for individuals undergoing treatment or recovery.

During initial testing on a healthy cohort, the device exhibited exceptional accuracy, effectively interpreting vocal cord movements into predetermined sentences, facilitating silent communication. The research team envisions further developments in machine learning to enhance the device’s vocabulary, paving the way for future trials involving individuals with speech disorders.

This groundbreaking innovation holds the promise of transforming the lives of millions grappling with communication challenges. By offering a seamless and effective means of communication, the AI-powered wearable device represents a beacon of hope for those who have long been silenced, ushering in a new era of inclusivity and empowerment in the realm of assistive technology.
