Engineers at UCLA have introduced a groundbreaking technology with the potential to revolutionize communication for individuals facing speech challenges, such as those recovering from laryngeal cancer surgeries or dealing with dysfunctional vocal cords. Published in the journal Nature Communications, this innovative device, approximately the size of an inch square, represents a significant advancement in speech generation technology. Spearheaded by Jun Chen and his team, the device is worn externally on the skin near the throat and operates by capturing bioelectric signals from the larynx muscles. These signals are then processed through a sophisticated machine-learning algorithm, achieving speech generation accuracy approaching an impressive 95%. The device consists of two main components: a self-powered sensing component and an actuating component, both constructed from silicone and magnetically induced layers. The sensing component utilizes magnetoelastic technology to detect movements of the laryngeal muscles, converting them into electrical signals. These signals are subsequently processed to generate speech signals. Simultaneously, the actuation component supplies the necessary current to the motor, translating the signals into audible speech output. This breakthrough technology holds immense promise for individuals with speech impairments, offering them newfound independence and the ability to communicate effectively. Furthermore, it represents a significant step forward in the field of assistive technology, demonstrating the potential of interdisciplinary research to address complex challenges and improve quality of life for individuals worldwide.
