3. INTRUDUCTION
❑Amazing solution for those who had lost their voice but wish speak over phone.
❑ it is a technology that helps you to transmit information without using your vocal
cords.
❑Detects every lip movement and internally converts the electrical pulses into
sounds signals and sends them neglecting all other surrounding noise.
❑ Hence person on other end of phone receivers the information in audio.
❑ Development at the Karlsruhe Institute of Technology, Germany
❑ Expected in the next 5-10 years. Once launched, will have a drastic effect and
with no doubt, will be widely used.
4. NEED FOR SILENT SOUND
❑An end to embarrassed situations such as:
➢Whenever we are talking on a cell phone in a crowd, then actually
we are “not talking, because of disturbance and noise around us.
➢In the case of an urgent call in a meeting, apologetically rushing out
of the room in order to answer or call the person back.
5. METHODS
❑ Two Methods for using Silent Sound Technology
1.Electromyography
2.Image processing
6. ELECTROMYOGRPHY (EMG)
❑Technique for evaluating and recording the electrical activity produced by
skeletal muscles.
❑Performed using an instrument called an “Electromyograph”, to produce a
record called an “Electromyogram”.
❑Electromyograph detects the electrical potential
generated by muscle cells are electrically or neurologically activated.
❑monitored signals are converted into electrical signals that can then be
turned into speech.
7. EMG - PROCEDURE
❑There are two types of EMG
1. Surface EMG
➢Four senser are used they are vibration ,
pressure, motion and electromagnetic
sensor
2.Intramusclular EMG
➢ A Needle electrode or a needle containing
two fine - wire electrodes is inserted
through the skin into the muscle tissue.
➢ The insertional activity provides valuable
information about the states of the muscle
and its innervating nerve.
9. IMAGE PROCESSING (ULTRASOUND SSI)
➢Another way to obtain information on the vocal tract configuration is
via imaging techniques.
➢Ultrasound imagery is non- invasive and clinically safe procedure
which makes possible the real-time visualization
➢An ultrasound transducer, placed beneath the chin, can provide a
partial view of the tongue surface.
11. ADVANTAGES
➢Helping people who have lost their voice due to illness or accident.
➢We can make silent cells even if we are standing in crowded place.
➢Very useful for sharing confidential information like secret PIN
number on phone at public place.
12. DISADVANTAGES
➢It will be like always talking to robot.
➢This technology will be very costly for a common man.
13. APPLICATIONS
➢Silent Sound Techniques is applied in military for communicating
secret/confidential matters to others.
➢ This technology can be best utilized by astronauts & dumb
peoples.
14. FUTURE PROSPECT
➢Without having electrodes & sensors hanging all around the face,
these electrodes & sensors will incorporated in to cell phone.
➢Features like lip reading based on image processing & recognition
these are incorporated in to cell phones rather then using computers
(ultrasound SSI).
15. CONCLUSION
➢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 will be use in
our day to day life.
