  1. 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. 2. SILENCE IS THE BESTANSWER FOR ALLTHE SITUATIONSEVEN YOUR MOBILEUNDERSTANDS……..
  3. 3. CONTENTS INTRODUCTION NEED OF SILENT SOUND ORIGINATION METHODS RESEARCH APPLICATION FUTURE PROSPECT CONCLUSION
  4. 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. 5. WHYNEEDED????...
  6. 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. 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. 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. 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. 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. 11. METHODSSilent Sound Technology is processedthrough some ways or methods….. 1) Electromyography(EMG) 2) Image Processing
  12. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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.
