Bioengineers at UCLA have created a thin, flexible device that attaches to the neck, translating larynx muscle movements into audible speech via machine learning. This breakthrough technology helps those with voice disorders caused by vocal cord issues, laryngeal cancer surgeries, or other conditions. Developed by Jun Chen and his team, the device uses a bioelectric system and magnetoelastic sensors to convert muscle movements into electrical signals, which are then translated into speech with around 95% accuracy. This innovative technology aims to provide a non-invasive, wearable solution for communication challenges faced by individuals with voice disorders, representing a significant advancement in enhancing quality of life.
