Silent sound technology

  2. 2. Contents: •Introduction • Need of silent sound technology • Origination • Methods • Applications • Restrictions • Future prospects • Conclusion 11/24/2013 2
  3. 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. 11/24/2013 3
  4. 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. 11/24/2013 4
  5. 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. 11/24/2013 5
  6. 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. 11/24/2013 6
  7. 7. -:METHODS:• “SILENT SOUND TECHNOLOGY” is processed through some way or methods…. • ELECTROMYOGRAPHY(EMG) • IMAGE PROCESSING 11/24/2013 7
  8. 8. ELECTROMYOGRAPHY: • It is a technique which monitors tiny muscular movements and pulses generated by it. The transducers involved converts pulses into electric signals. silent/ laryngectomized speaker camera speech Silent Vocoder Ultrasound probe 11/24/2013 8
  9. 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. 11/24/2013 9
  10. 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. 11/24/2013 10
  11. 11. Continued…. Analysis of remotely sensed data is done using various image processing techniques and methods that includes: • Analog image processing • Digital image processing 11/24/2013 11
  12. 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. 11/24/2013 12
  13. 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. 11/24/2013 13
  14. 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. 11/24/2013 14
  15. 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. 11/24/2013 15
  16. 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. 11/24/2013 16
  17. 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. 11/24/2013 17
