3. WHAT IS SILENT SOUND TECHNOLOGY ?
• Technology that helps to transmit
information without using vocal cords.
• It transform lip movements into a
computer generated sound.
• Hence person on other end of phone
receives the information in audio.

4. WHY WE NEED SILENT SOUND TECHNOLOGY???
• For a better way of communication in noisy public
place.
• Gives a better and new way of communication for
those peoples who lost their voice.
•Helps peoples
for giving any confidential
information over a phone without worrying about
others.
• As the electronic pulses are universal and can be
immediately converted into any other language of
your choice.

5. ORIGINATION:
• The idea of interpreting silent speech with computer
was popularized in the year 1968.
•“SILENT SOUND TECHNOLOGY” was demonstrated
in CEBIT-2010 .
• This technology is being developed by scientists of
Karlsruhe Institute of Technology (KIT), Germany.

6. HOW WE SPEAK…..???
• When we generally
speak
aloud, air passes through Larynx
and tongue. Words are produced
using articulator muscle in
mouth and jaw region.
• Even by saying words without
producing sounds weak electric
current are sent from brain to
speech muscles.

7. -:METHODS:• “SILENT SOUND TECHNOLOGY” is processed
through some way or methods….
• ELECTROMYOGRAPHY(EMG)
• IMAGE PROCESSING

8. ELECTROMYOGRAPHY:
• It is a technique which monitors tiny
muscular movements and pulses generated by
it. The transducers involved converts pulses
into electric signals.

9. HOW IT WORKS…..????
• A needle electrode or a needle
containing two fine wire
electrodes is inserted through
the skin into the muscle tissue.
• Science
skeletal
muscles
differs in internal structure so
electrode has to be places at
various location to get accurate
signals.
• Thus
by this way speech can be communicated
without sound.

10. IMAGE PROCESSING:-
• 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 data.

11. Continued….
Analysis of remotely sensed data is done
using various image processing techniques
and methods that includes:
• Analog
image processing
• Digital image processing

12. Analog image processing:
• Analog processing techniques is applied to hard copy
data such as photographs or printouts.
•It
adopts certain
elements of interpretation,
such as primary element, spatial arrangement etc.
Digital image processing:
• It is the use of computer algorithm to perform image
processing on digital image.
• In the most basic terms, digital processing refers to
any manipulation of electronic data to produce a
specific data.

13. -:RESEARCH:• “Lost calls”.
• Research found that “lost calls” of $ 20 billion per
year worldwide.
• Now research is going on a technology that can be
used in Office environment.

14. -:APPLICATIONS:• For astronauts.
• Effective calls in crowded place.
• Can use without vocal cord.
• Useful to Aphasia (speaking disorder ).
• It gives confidentiality.
• Since the electrical signals are universal they can be
translated into any language(currently being German, English
& French).
• In military works.

15. -:RESTRICTIONS:-
• Technology is difficult to apply in some language ( Chinese).
• Complicated to identify person and emotions.
• This device presently needs nine leads to be attached to our
face which is quite impractical to make it usable.

16. -:FUTURE PROSPECTS:-
• Speech recognition technology.
• Without having electrodes hanging all around your
face, these electrodes will be incorporated into cell
phones.
• Nano technology will be a mentionable step towards
making the device handy.

17. -:CONCLUSIONS:-
•Engineers claim that the device is working
with 99 percent efficiency.
• Silent Sound Technology one of the recent
trends in the field of information technology
implements “Talking without Talking”.
• It will be done of the innovating and useful
technology and in future this technology will
be use in day to day life.
