1. SILENT SOUND TECHNOLOGY SUBMITTED BY:- NEHA TYAGI
SUBMITTED TO:- MCA III SEM GRP B MS. PRATISHTA GUPTA ROLL NO.
45 BANASTHALI UNIVERSITY JAIPUR CAMPUS
2. SILENCE IS THE BESTANSWER FOR ALLTHE SITUATIONSEVEN YOUR
MOBILEUNDERSTANDS……..
3. CONTENTS� INTRODUCTION� NEED OF SILENT SOUND� ORIGINATION�
METHODS� RESEARCH� APPLICATION� FUTURE PROSPECT�
CONCLUSION
4. INTRODUCTION� Silent Sound Technology is a techonogy for mobile
phones that helps you communicate in noisy places too .� It is a technolgy that
will help reduce noise polution to a great extent.�The uses of this technology
are immense for people who are vocally challanged or have been rendered
mute due to accident.
5. WHYNEEDED????...
6. NEED• An end to embarrassed situations such as: – 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.
7. ORIGINATION� The idea of interpreting silent speech electronically or with a
computer was popularized in the 1968 Stanley Kubrick science-fiction film
��2001 – A Space Odyssey�.� A major focal point was DARPA Advanced
Speech Encoding Program (ASE) of the early 2000‘s which funded research on
low bit rate speech synthesis and aural speaker recognizability and
acoustically harsh environment. Contd….
8. Continued…..� In 2010 at CEBIT one of the largest trade fair a new concept
called “SILENT SOUND TECHNOLOGY” was demonstrated.� This technology
is being developed by scientists of Karlsruhe Institute Of Technology (KIT),
Germany .
9. HOW WE SPEAK…….� When we generally speak aloud , air passes
through Larynx and tounge. Words are produced using articulator muscle in
mouth and jaw region.
10. Continued….� Recently it is proved that when we are about to speak due to
reflex action of muscles the articulate muscle becomes active irrespective of
wheter air is passed through them or not .� Even by saying words without

producing sound weak electric currents are sent from brain to speech muscles.
This phenomenon is called ELECTROMYOGRAPHS
11. METHODSSilent Sound Technology is processedthrough some ways or
methods….. 1) Electromyography(EMG) 2) Image Processing
12. ELECTROMYOGRAPHY• It is a technique that monitors tinymuscular
movements and pulsesgenerated by it. The transducersinvolved convert the
pusles intoelectrical signals.• The Silent Sound Technology uses
Electromyography monitoring tinymuscular movements that occurwhen we
speak.
13. WORKING OF ELECTROMYOGRAPHY• A Needle electrode or a needle
containing two fine - wire electrodes is inserted through the skin into the
muscle tissue.• Normal muscles at rest make certain normal electrical
sounds,when the needle is inserted into them. Then the electrical activity when
muscle is at rest is observed .• Each electrode track gives only a very normal
picture of the activity of the activity of the whole muscle . Contd….
14. Continued…• Since skeletal muscle differs in internal structure so
electrode has be be places at various locations to obtain accurate signal.•
Thus by this way the speech cab be comunicated without sound.
15. 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 the data.• In the present context, overhead
prospective are employed to analyze the picture.
16. IMAGE PROCESSING TECHNIQUES Analysis of remotely sensed data is
done using various image processing techniques and methods that includes: *
Analog image processing * Digital image processing
17. ANALOG IMAGE PROCESSING• Analog processing technique is applied
to hard copy data such as photographs or printouts.• It adopts certain
elements of interpretation, such as primary element, spatial arrangement etc.,•
With the combination of multi-concept of examining remotely sensed data it
allows us to make a verdict not only as to what an object is but also its
importance.• Apart from these it also includes optical photogrammetric
techniques allowing for precise measurement of the height, width, location, etc.
of an object.
18. DIGITAL IMAGE PROCESSING• Digital Image Processing involves a
collection of techniques for the manipulation of digital images by computers.• It
contain some flaws. To overcome the flaws and deficiencies in order to get the
originality of the data, it needs to undergo several steps of processing.• Digital
Image Processing undergoes three general steps: 1) Pre-processing Display 2)
Enhancement 3) Information extraction
19. PREPROCESSING• Pre-processing consists of those operations that
prepare data for subsequent analysis that attempts to correct or compensate
for systematic errors.• Then analyst may use feature extraction to reduce the
dimensionality of the data.• Thus feature extraction is the process of isolating
the most useful components of the data for further study while discarding the
less useful aspects.• It reduces the number of variables that must be
examined, thereby saving time and resources.
20. ENHANCEMENT• Improves the interpretability of the image by increasing
apparent contrast among various features in the scene.• The enhancement
techniques depend upon two factors mainly :- 1)The digital data (i.e. with
spectral bands and resolution) 2)The objectives of interpretation• Common
enhancements include image reduction, image rectification, image
magnification, contrast adjustments, principal component analysis texture
transformation and so on.
21. INFORMATION EXTRACTION• In Information Extraction the remotely
sensed data is subjected to quantitative analysis to assign individual pixels to
specific classes.• It is then classified.• It is necessary to evaluate its
accuracy by comparing the categories on the classified images with the areas
of known identity on the ground.• The final result of the analysis consists of
maps (or images), data and a report. Then these are converted to
corresponding signals.
22. RESEARCHWith millions of phones in circulation, there isgreat potential for
increasing earnings by savinglost calls - telephone calls that go
unansweredbecause the user is in a situation in which he or shecannot speak
not just in business meetings, buteveryday situations. According to research,
theselost calls are worth $20 billion per yearworldwide. For the cellular
operator, these arepotential earnings. When these lost calls
becomeanswerable, and can be conducted without makinga sound, there is a
tremendous potential forincreased profits. Now the research is going
ontechnology that can be used in Office Environment
23. APPLICATIONSTechnology opens up a host of application such as
mentioned below :� Helping people who have lost their voice due to illness or
accident.� Telling a trusted friend your PIN number over the phone without
anyone eavesdropping — assuming no lip-readers are around.� Silent Sound
Techniques is applied in Military for communicating secret/confidential matters
to others.
24. FUTURE PROSPECTS• Silent sound technology gives way to a bright
future to speech recognition technology from simple voice commands to
memorandum dictated over the phone all this is fairly possible in noisy public
places.• Without having electrodes hanging all around your face, these
electrodes will be incorporated into cellphones .• Nano technology will be a
mentionable step towards making the device handy.
25. CONCLUSION• 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 one of
the innovation and useful technology and in mere future this technology will be
use in our day to day life.
