INTRODUCTION
When we are in movie theatre, bus, there is lot of noise
around us. We can’t speak properly on a mobile phone .In
future this problem is eliminated by Silent Sound
Technology .It is a technology that helps you to transmit
the information without using vocal cords. This
technology notices every lip movement and transforms
them into computer generated sound that can be
transmitted over phone. Hence person on another end of
phone receives information in audio. Silent sound
technology is the perfect solution for the people who lost
their voices but wish to speak on mobile devices.

3. NEED FOR SILENT SOUND TECHNOLOGY:
• For better way of communication in noisy public place.
• Gives a better and new way of communication for those
peoples who lost their voices.
• Helps peoples for giving any confidential information’s
over a phone without worrying about others.

METHODS
Silent Sound Technology is processed through some ways or
methods
They are:
Electromyography(EMG)
•
Image Processing
•

5. :
ELECTROMYOGRAPHY
•The Silent Sound Technology uses electromyography, monitoring tiny
muscular movements that occur when we speak. Monitored signals
are converted into electrical pulses that can then be turned into speech,
without a sound uttered.
•It is a technique which monitors tiny muscular movements and pulses
generated by it. The transducers involved converts the pulses into
electric signals.
•Electromyography sensors attached to the face records the electric
signals produced by the facial muscles, compare them with pre-
recorded signal pattern of spoken words.

IMAGE PROCESSESING
•Image processing is processing of images using mathematical operations.
•By using any form of signal processing for which the input is an image,
such as a photograph or video frame.
•The output of image processing may be either an image or a set of
characteristics or parameters related to the image.
•In the silent sound technology the output of this image processing is an
audio record.

ADVANTAGES
• Helping people who have lost their voice
• We can make silent calls even if we are standing in crowded
place.
• Very useful for sharing confidential information like secret PIN
number on phone at public place

10. :
DISADVANTAGES
• It will be like always talking to robot.
• This technology will be very costly for a common man.

11. •
• Silent Sound Technology, one of the recent trends in the field
of Information technology implements Talking Without Talking’.
•
• Engineers claim that the device is working with 99 percent
efficiency.
•
• It will be one of the innovative and useful technology and in
mere future this technology will be of use in day to day life.
