Avoid Noisy Communications.. Silent Sound Technology as an solution.

You are in a movie theater or noisy restaurant or a bus etc where there is lot of noise around is big issue while talking on a mobile phone. But in the future this problem is eliminated with ”silent sounds”, a new technology unveiled at the CeBIT fair that transforms lip movements into a computer-generated voice for the listener at the other end of the phone.
The device, developed by the Karlsruhe Institute of Technology (KIT), uses electromyography, monitoring tiny muscular movements that occur when we speak and converting them into electrical pulses that can then be turned into speech, without a sound uttered.
‘Silent Sound’ technology aims to notice every movement of the lips and transform them into sounds, which could help people who lose voices to speak, and allow people to make silent calls without bothering others. Rather than making any sounds, your handset would decipher the movements your mouth makes by measuring muscle activity, then convert this into speech that the person on the other end of the call can hear. So, basically, it reads your lips.
“We currently use electrodes which are glued to the skin. In the future, such electrodes might for example by incorporate into cell phones,” said Michael Wand, from the KIT.
The technology opens up a host of applications, from helping people who have lost their voice due to illness or accident to telling a trusted friend your PIN number over the phone without anyone eavesdropping — assuming no lip-readers are around.
The technology can also turn you into an instant polyglot. Because the electrical pulses are universal, they can be immediately transformed into the language of the user’s choice.
“Native speakers can silently utter a sentence in their language, and the receivers hear the translated sentence in their language. It appears as if the native speaker produced speech in a foreign language,” said Wand.
The translation technology works for languages like English, French and German, but for languages like Chinese, where different tones can hold many different meanings, poses a problem, he added.
Noisy people in your office? Not any more. “We are also working on technology to be used in an office environment,” the KIT scientist told AFP.
The engineers have got the device working to 99 percent efficiency, so the mechanical voice at the other end of the phone gets one word in 100 wrong, explained Wand.
“But we’re working to overcome the remaining technical difficulties. In five, maybe ten years, this will be useable, everyday technology,” he said.

Internet protocol

Background of Internet Protocols

In the mid-1970s, the Defense Advanced Research Projects Agency (DARPA) became interested in
establishing a packet-switched network to provide communications between research institutions in
the United States. DARPA and other government organizations understood the potential of
packet-switched technology and were just beginning to face the problem virtually all companies with
networks now have—communication between dissimilar computer systems.
With the goal of heterogeneous connectivity in mind, DARPA funded research by Stanford
University and Bolt, Beranek, and Newman (BBN) to create a series of communication protocols.
The result of this development effort, completed in the late 1970s, was the Internet Protocol suite, of
which the Transmission Control Protocol (TCP) and the Internet Protocol (IP) are the two best
known.
The Internet protocols can be used to communicate across any set of interconnected networks. They
are equally well suited for local-area network (LAN) as well as wide-area network (WAN)
communications. The Internet suite includes not only lower-layer specifications (like TCP and IP),
but also specifications for such common applications as mail, terminal emulation, and file transfer.
