Spoke on the Phone without Making a Sound

German scientists in the discovery that one can make a person talking on the phone without making a sound. This next generation technology will be very helpful, especially for mobile users who travel a lot when in noisy places and have to find somewhere quiet to get on the phone. They did not need to shout from the crowd so that their voices could be heard the other person.  By measuring small electrical signals from the muscles involved in the conversation activity, the scientists developed a device that can record what someone says, though his voice was not heard.

The system then produces a clear sound in words that have been synthesized version. This next generation technology on display for the first time at CeBIT event which is a routine technology exhibition held every year German. Professor Tanja Shultz of the Karlsruhe Institute of Technology who developed this technology says, he was inspired by the people who need it on the phone while in the train.

"The person who was next to me had to shout to talking on the phone. I think, something like this should be changed," said Tanja. The device developed by Tanja using electromyography, which is used to diagnose nerve damage. This tool requires nine electrodes to be attached to the user's face.  Tanja had not intended to market the technology in bulk findings. But she did not think the possibility if one day he will work with handset vendors to apply the findings of the next generation technology of this phone.
