  • Researchers at UCLA have developed a wearable, adhesive device using AI technology to help people with paralyzed vocal cords regain their voice function.
  • The device can detect movement in larynx muscles and translate those signals into audible speech with nearly 95% accuracy.

In a groundbreaking development, bioengineers at the University of California, Los Angeles have created a wearable, adhesive device that uses artificial intelligence to help people with paralyzed vocal cords speak again. Vocal cord paralysis can result from various causes such as diseases, nerve damage, and injuries, making it difficult for individuals to communicate and even breathe properly. The new invention consists of a soft, thin, stretchy device that can be attached to the skin outside the throat, measuring just over 6.5 square centimeters.

The device, developed by Prof. Jun Chen and his team, is capable of detecting movement in the larynx muscles and translating those signals into audible speech with the help of machine learning technology. The two-component device includes a self-powered sensing component and an actuation component, both containing layers of biocompatible silicone compound and magnetic induction coils. The device weighs about seven grams and is just 1.5 millimeters thick, making it non-invasive and comfortable for users.

During experiments, the researchers tested the technology on healthy adults and achieved an impressive overall prediction accuracy of 94.68%. Participants were able to pronounce sentences using the device, showcasing its potential to assist individuals with voice disorders. Moving forward, the research team aims to expand the vocabulary of the device through machine learning and test it in individuals with speech disorders. This innovation offers a promising solution for those who have lost their voice chronically or permanently, providing a non-invasive option for communication and voice recovery.
