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.

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.

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.

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.

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

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

• 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.
HOW IT WORKS…..????
• Thus by this way speech can be communicated without sound.

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.

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

-: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.

-: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.

-: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.
04/08/2023 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.
04/08/2023 17
•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.
