It is a technology that helps you to transmit information without using your
vocal cords
This technology aims to notice lip moments and transform them into a
computer generated sound .

The idea was first interpreting in the 2001 Stanley Kubrick.
In 2010 at CEBIT implement new concept called “SILENT SOUND
TECHNOLOGY”
Being developed by scientist Karlsruhe Institute Of Technology(KIT),Germany

A person working his silence , but vibrating cell phone in a meeting, lecture
or any crowded area.
You are in a movie theatre or noisy restaurant or a bus etc.
To reduce noise pollution.

When we generally speak aloud, air passes through larynx & the tongue.
Words are produced using articulator muscles in the mouth & jaw region.
it is proved that when we are about to speak due to reflex action of muscles
the articulate muscle
HOW TO WORK?

IN INTERFACEING WE USE FOUR DIFFERENT KIND OF
TRANSDUCERS
Vibration sensors
Pressure sensor
Electromagnetic sensor
Motion sensor
SILENT SPEECH INTERFACES

METHODS
Two methods for using Silent Sound Technology
1.Electromyography
Monitoring tiny muscular moments that occur when we speak.
Signals are converted into electrical pulses that can the be turned into
speech without a sound uttered.
2. Image Processing
Converting digital data tape into a film image with minimal
corrections and calibrations.
Large mainframe computers employed for sophisticated interactive
manipulation of the data.

ELECTROMYOGRAPHY
It is a technique which monitors tiny muscular moment and pulses
generated by it.
Electronic signal produce by the facial muscles ,compare them with
prerecorded signal pattern of spoken words

Working of electromyography
Electrodes are inserted through the skin into the muscle tissue.
Each electrode track gives only a very local picture of the activity of whole
muscle.
Electrodes has to be placed at various locations to obtain an accurate
signal.

IMAGE PROCESSING
Converting digital data tape into a film image with minimal corrections and
calibrations.
Two types of image processing
Analog Image Processing
Digital Image Processing

ADVANTAGES & DISADVANTAGES
Advantages:
Native speakers can silently convert a sentence in their language, and the
receivers can hear the translated sentence in their language.
Allow people to make silent calls without bothering others.
Disadvantages:
Complicated to gets who you are talking.
Differentiating between people and emotions cannot be done.
Translation into majority of languages

APPLICATION
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 Technology is applied in military for communicating
secret/confidential matters to other.
We can make silent calls even if we are standing in a crowded place.

CONCLUSION
• Thus 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.
