A Danish designer, Mads Sudkhdev Hindhede, has developed the prototype of a spectacle that allows hearing-impaired people to read the text of a speech or a conversation displayed on its lenses. Called Babelfisk, it also allows the wearer to get that text automatically translated into his or her own language. The device uses microphones embedded in the frame and speech recognition software developed by Dragon Dictate. Hearing aid algorithms filter out speech in a noisy environment, showing where it comes from. Speech is turned into text and translated it into any of a number of foreign languages, if necessary. The glasses can be fitted with a flash memory card for recording purposes.
