Hearing aid technology that scans facial movements can lip read through masks

A hearing aid technology has been developed that scans your facial movements and uses an artificial intelligence (AI) to work out what is being said. Developed by engineers at the University of Glasgow, the system is even able to read the lips of people who are wearing a mask. The team trained algorithms with data collected by scanning people's faces with radar and Wi-Fi signals while they were speaking. This allowed the system to correctly interpret speech up to 95 per cent of the time for unmasked lips, and up to 83 per cent of the time with a mask. If integrated into hearing aids, it could help deaf and hard-of-hearing people to focus on sounds more easily in noisy environments.
