Silent Sound technology is a technology that helps you to transmit information without using your vocal cords. Silent
Sound technology is developed at the Karlsruhe Institute of Technology, Germany. This technology uses
electromyography. It monitors tiny muscular movements that occur when we speak and converting them into electrical
pulses that can then be turned into speech, without a sound uttered. It is very useful for those people who can’t speak.
By using this technology they can easily interact with the other persons. The benefit of this technology is that the
listener can hear voice clearly. This technology aims to notice lip movements & transform them into a computer
generated sound that can be transmitted over a phone. Hence person on other end of phone receive the information in
audio. The idea of interpreting silent speech electronically or with a computer has beenaround for a long time, and was
popularized in the 1968 Stanley Kubrick science-fiction film ‘‘2001-A Space Odyssey.”

In the 2010 CeBIT's "future park", a concept "Silent Sound" Technology demonstrated which aims to notice every
movement 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 your lips. Thus people can talk on their cell phones at the crowded place
without getting disturbed as show in Figure
