ACKNOWLEDGEMENTDreams never turn into reality unless a lot of efforts and hard work is put into it. And no effort ever bears fruit in the absence of the support and guidance. It takes a lot of efforts to make your way to the goal and having someone to guide you and help you is always a blessing. I would like to take this opportunity to thank a few who were closely involved in the completion of this endeavor. I am happy to take this opportunity to thank to people who helped me in the making of my seminar. I acknowledge the influence and inspiration of Miss Amal Lecturer in Electronics & Communication Engineering who made the entire seminar an exciting and enjoyable experience. At the outset, I thank God almighty for making my endeavor a success. I also express my gratitude to our beloved principal Dr. JOSEPHKUTTY JACOB, and Dr MANOJ V.J. Head of the Department, for providing me with adequate facilities, ways and means by which I was able to complete this seminar. I am also grateful to Miss Visanthi V P, Miss Sandhya Rajan, Annu Varghese, Sreenath S M, Jisbi Karthik and all other teachers of Electronics & Communication Engineering Department for their invaluable teaching, help and support without which the successful completion of this seminar would not have been possible.

SILENT SOUND TECHNOLOGY 2011

ABSTRACTEverybody has the experience of talking aloud in the cell phone in the midst of the disturbance while travelling in trains or buses. There is no need of shouting anymore for this purpose. Silent sound technology is the answer for this problem. The Silent sound technology is an amazing solution for those who had lost their voice but wish to speak over phone. It is developed at the Karlsruhe Institute of Technology and you can expect to see it in the near future. When demonstrated, it seems to detect every lip movement and internally converts the electrical pulses into sounds signals and sends them neglecting all other surrounding noise. It is definitely going to be a good solution for those feeling annoyed when other speak loud over phone. Silent Sound technology aims to notice every movements 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. This new technology will be very helpful whenever a person looses his voice while speaking or allow people to make silent calls without listurbing others, even we can tell our PIN number to a trusted friend or relative without eavesdropping . At the other end, the listener can hear a clear voice. the awesome feature added to this technology is that "it is an instant polyglot" I.E, movements can be immediately transformed into the language of the user's choice. This translation works for languages like English, French & German. But, for the languages like Chinese, different tones can hold many different meanings. This poses Problem said Wand. he also said that in five or may be in ten years this will Be used in everyday's technology.

INTRODUCTIONSilence is the best answer for all the situations even your mobile understands !

The word Cell Phone has become greatest buzz word in Cellular Communication industry.

There are lots and lots of technology that tries to reduce the Noise pollution and make the environment a better place to live in.

I will tell about a new technology known as Silent Sound Technology that will put an end to Noise pollution.

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 on Tuesday that transforms lip movements into a computer-generated voice for the listener at the other end of the phone. It is a technology that helps you to transmit information without using your vocal cords . This technology aims to notice lip movements & transform them into a computer generated sound that can be transmitted over a phone . Hence person on other end of phone receives the information in audio.

SILENT SOUND TECHNOLOGY 2011 In the 2010 CeBIT's "future park", a concept "Silent Sound" Technology demonstrated which 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. 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 movements 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 incorporated into cellphones, said Michael Wand, from the KIT.

SILENT SOUND TECHNOLOGY 2011 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 users 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 Gernan, 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 were working to overcome the remaining technical difficulties. In five, maybe ten years, this will be useable, everyday technology, he said.
