ACKNOWLEDGEMENT
Dreams 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 Mr. Shivram Meena Lecturer in Comuter Science Department 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 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 Mr. Krishnan MathUr, Mr. Shailendra and all other teachers of Computer Science Engineering Department for their invaluable teaching, help and support without which the successful completion of this seminar would not have
been possible.

ABSTRACT
Everybody 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.

INTRODUCTION
Silence 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.
General
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.
