Everyone has the experience of speaking loudly on the phone during a violent incident while traveling by train or bus. I no longer need to shout for this purpose. It would certainly be a good solution for those who feel frustrated when others speak loudly over the phone. "Silent Sound Technology" aims to recognize all the movements of the lips and convert them into sounds, which can help speechless people to speak, and allow people to make silent calls without disturbing others. Instead of making any noise, your handset will determine the movement of your mouth by measuring muscle activity, and this translates into speech that no one can hear. So, basically, it reads your lips. This new technology will be very useful whenever someone loses voice when speaking or allows people to make silent calls without interrupting others, even we can tell our PIN number to a trusted friend or relative without listening. On the other hand, the listener may hear a clear voice. An amazing feature added to this technology is the "fast polyglot" which can be quickly translated into the language of the user's choice. This translation works for languages such as English, French, and German”. Silent sound technology is an excellent solution for those who have lost their voice but wish to communicate by telephone. This technology allows people to make calls without producing sounds. Developed at Karlsruhe Institute of Technology. This technology basically detects every movement of the lips and internally converts electrical pulses into sound signals and transmits separation to all other surrounding sounds. techniques used to detect trivial sounds, namely electromyography and image processing. This study reviews the future of technological advances that are rapidly changing in the preferred language but, in languages such as different Chinese tones can capture many different meanings. This technology is 99% effective, can be seen on the market for another 5-10 years, and will be used in everyday technology.
