This document discusses silent sound technology, which allows people to transmit voice information through their lip movements without actually speaking. It works by using electromyography to detect tiny muscle movements when speaking and converting them into electrical pulses and sound signals. Alternatively, it can use image processing of lip movements. The technology was developed in Germany and has applications for helping those who have lost their voice communicate over the phone without disturbing others. It also allows for silent phone calls even in public places and could be incorporated into future cell phones through improved sensors.

- 1. CMR TECHNICAL CAMPUS UGC AUTONOMOUS ACCREDITED BY NBA & NAAC WITH A GRADE APPROVED BY AICTE, NEW DELHI AND AFFILIATED TO JNTU, HYDERABAD TECHNICAL SEMINAR on SILENT SOUND TECHNOLOGY Silent sound TSILE
- 2. Introduction • Silent sound Technology is an amazing solution for those who had lost their voice but wish to 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 sound signals and sends them neglecting all other surrounding noise. • Hence person on other end of phone receives the information in audio. It is developed at the Karlsruhe institute of Technology, Germany. • Hence person on other end of phone receives the information developed at the Karlsruhe institute of Technology, Germany.
- 3. Purpose of Silent Sound Technology • This new technology will help people who have lost their voice as a result of accident or cannot speak loudly again as result of old age. • It allows people to make silent calls without disturbing others, even we can tell our pin number to a trusted friend or relative without eaves dropping. • Even though we are in the public places, we can attend the phone calls .In the other end, the receiver receives the information without any disturbances.
- 4. Methods There are two methods for using silent sound technology I. Electromyography II. 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. • Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. • An electromyography detects the electrical potential generated by muscle cells, when these cells are electrically or neurologically activated.
- 6. Image Processing Image processing is 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.
- 7. Future Prospect • Without having electrodes & Sensors hanging all around the face ,these electrodes & sensors will incorporated to cell phones. • Features like lip reading based on image processing & recognition these are incorporated into cell phones rather than using computers.
- 8. Advantages • Helping people who have lost their voice due to illness or accident. • 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.
- 9. Disadvantages • It always be like always talking to Robot. • This technology will be very costly for a common man.
- 10. 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 used in our day to day life. ‘Silent Sound’ technology aims to notice every movements of the lips and transform them into sounds, which could help people who lose voices to speak, and allow people to make silent calls without bothering others.
