2. The Silent sound technology is an amazing solution for those who had lost their
voice but wish to communicate over the phone. This technology basically allows
people to make calls without producing sounds. It is developed at the Karlsruhe
Institute of Technology. This technology basically detect every lip movement and
internally converts the electrical pulses into sounds signals and sends them
neglecting all other surrounding noise. This report outlines the history associated
with this technology presenting the method or techniques used in achieving silent
sounds, which are electromyography and Image processing. This research reviews
the underlined futures of the technology that immediately transforms into the
language of the user's choice but, for the languages like Chinese different tones
can hold many different meanings. This technology basically works with 99%
efficiency, and can be seen in the market in another 5-10 years and will be used in
every day’s technology

4.  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.
 This presentation tells about a new technology known as Silent Sound
Technology that will put an end to Noise pollution

5. A person answering his silent, but vibrating cell phone in a meeting,
lecture or performance, and whispering loudly, “ I can’t talk to you right
now” .
In the case of an urgent call, apologetically rushing out of the room in
order to answer or call the person back.

6. Silent Sound Technology is processed through some ways or methods.
They are:
Electromyograpy(EMG)
Image Processing

7. The Silent Sound Technology uses electromyography, monitoring tiny
muscular movements that occur when we speak.
Monitored signals are converted into electrical pulses that can then be
turned into speech, without a sound uttered.
Electromyography (EMG) is a technique for evaluating and recording the
electrical activity produced by skeletal muscles.
An electromyography detects the electrical potential generated by muscle
cells, when these cells are electrically or neurologically activated

8.  A needle containing two fine-wired electrodes is
inserted through the skin into the muscle tissue
 Then the electrical activity when the muscle is
at rest is observed. Each electrode track gives
only a very local picture of the activity of the
whole muscle
 Because skeletal muscles differ in the inner
structure, the electrode has to be placed at various
locations to obtain an accurate signal

10.  The simplest form of digital image processing converts the digital data
tape into a film image with minimal corrections and calibrations.
 Then large mainframe computers are employed for sophisticated
interactive manipulation of the data. In the present context, overhead
prospective are employed to analyze the picture.
 Most image-processing techniques involve treating the image as a two-
dimensional signal and applying standard

12.  Helping people who have lost their voice
 We can make silent calls even if we are standing in
crowded place.
 Very useful for sharing confidential information like
secret PIN number on phone at public place

13.  It will be like always talking to robot.
 This technology will be very costly for a common
man.

14. The Technology opens up a host of application such as mentioned
below:
As we know in space there is no medium for sound to travel therefore
this technology can be best utilized by astronauts.
Helping people who have lost their voice due to illness or accident.
We can make silent calls even if we are standing in a crowded place.

15.  Silent Sound Technology, one of the recent trends in the field of
Information technology implements ‘Talking Without Talking’.
 Engineers claim that the device is working with 99 percent
efficiency.
 It will be one of the innovative and useful technology and in mere
future this technology will be of use in day to day life.

17.  Silent sound technology gives way to a bright future to
speech recognition technology.
 Without having electrodes hanging all around your
face, these electrodes will be incorporated into cell
phones .
 Also reducing the time taken to process the image in
digital image processing.
