An anonymous reader writes: Scientists at Georgia Tech are developing silent speech systems that can enable fast and hands-free communication with wearable devices, controlled by the user's tongue and ears. As seen with open source project Eyedrivomatic, the researchers want to apply the technology to provide a device control solution for people who are disabled. They suggest it could also be used by those working in a loud environment in need of a quiet way to communicate with their wearable devices. The prototype involves a combination of tongue control with earphone-like pieces each installed with proximity sensors to map the changing shape of the ear canal. Every word manipulates the canal in a different way, allowing for accurate recognition.
