Nowadays whenever we are talking on a cell phone in a crowd, then actually we are not talking, we are
yelling because of lots of disturbance and noise around us. However,there is no need to scream to convey our message
and wasting our energy anymore.For this purpose a new technology known as the “Silent Sound Technology” has been
introduced that will put an end to the noise pollution. The Silent sound technology is a perfect solution for those people
who have lost their voice but wish to speak on mobile phones. It is developed at the Karlsruhe Institute of Technology
and you can expect to see it in the near future. When this technology is used, it detects every lip movement and
internally converts the electrical pulses into sounds signals and sends them neglecting all other surrounding noise. It is
going to be really beneficial for the people who hate talking loudly on cell phones. “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. Rather than making any sounds, your handset would
decipher the movements your mouth makes by measuring muscle activity, then convert this into speech that the person
on the other end of the call can hear. So, basically, it reads our lips. Another important benefit of this technology is that
it allows you to communicate to any person in the world as the electrical pulse isuniversal, it can be converted into any
language depending upon the users choice. This technology can be usedfor languages like English, French & German
but not for languages like Chinese because different tones hold different meaning in Chinese language. This new
technology will be very helpful whenever a person loses his voice while speaking or allow people to make silent calls
without disturbing others, thus now we can speak anything with our friends or family in private without anyone
eavesdropping. At the other end, the listener can hear a clear voice. This device works with 99% efficiency, and can
been seen in the market in another 5-10 years and once launched it will have a drastic effect and with no doubt it will
be widely used.
