Lip-Reading Technology Makes Debut At CeBIT

Researchers have developed a prototype technology which could allow people to have mobile conversations without making any sound.

The technology revolves around electromyography, a technique for recording electrical activity produced by human muscles.

The prototype device, which is on display at the CeBIT electronics fair in Hanover, Germany, will be able to turn small electrical signals sent by the face muscles, even without a single syllyable being uttered, and convert the signals into a synthesized voice with the help of a computer.

Explaining the functionality of the lip-reading technology, Professor Tanja Shultz of the Karlsruhe Institute of Technology, a member of the team that developed the ingenious technology, told the BBC that the device uses 9 electrodes that are attached to a user's face, and added that "These capture the electrical potentials that result from you moving your articulatory muscles. Those are the muscles that you need in order to produce speech."

The professor also explained the possibilities posed by this ground breaking technology, which include the use of the technology as a mobile translation device, which might allow users to speak into their phones in their mother tongues with the text being translated into English.
