4. Silent Speech Interface
These are the interfaces that are used in S.S.T.
1. Pressure Sensor.
2. Vibration Sensor.
3. Motion Sensor.
4. Electromagnetic Sensor.
Methods…..
“SILENT SOUNDTECHNOLOGY” is processed through some
way or methods….
1. Electromyography (EMG).
2. ImageProcessing.

5. 1. Electromyography (EMG):
• EMG is a technique used in SST for evaluating and
recording the electrical activity produced by
skeletal muscles.
• An EMG detects electrical potential generated by
muscle cells when these cells electrical or
neurologically activated.
• An EMG is performed using an instrument called
an Electromyograph to produce a record called an
Electromyogram.

 Image processing is a form of signal processing for which
the input is an image such as photograph or video frame and
output of imageprocessing may be either an image ora set of
characteristics.
Most image processing technics involves treating the image
as a2-Dsignals.
2. Image Processing:

8. Application…
For astronauts.
Effective callsin crowded place.
Can use without vocal cord.
Useful to Aphasia(speaking disorder ). .
In military works.

9. Restriction…
 By this technology only majority languages can be
transmitted.
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.

10. Future prospect….
•Speech recognitiontechnology.
•Withouthaving electrodeshanging allaroundyourface,these
electrodeswill be incorporatedintocell phones.
•Nanotechnologywill beamentionablestep towardsmaking t
he device handy.

11. Conclusion….
•Engineers claim that the device is working with 99 percent
efficiency.
•Silent Sound Technology one of the recent trends in the field of
informationtechnologyimplements “TalkingwithoutTalking”.
•It will be done of the innovating and useful technology and in
futurethistechnologywillbeuse in daytodaylife.
