You are in a movie theater or noicy restaurent or a bus etc where there is lot of noice around is big issue while talking on a mobile phone. But in the future this problem is eliminated with “silent sounds”, a new technology unveiled at the CeBIT fair on Tuesday that transforms lip movements into a computer-generated voice for the listener at the other end of the phone.

The device, developed by the Karlsruhe Institute of Technology (KIT), uses electromyography, monitoring 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.Crowd Talking On Mobile 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 your lips.

“We currently use electrodes which are glued to the skin. In the future, such electrodes might for example by incorporated into cellphones,” said Michael Wand, from the KIT.

The technology opens up a host of applications, from helping people who have lost their voice due to illness or accident to telling a trusted friend your PIN number over the phone without anyone eavesdropping — assuming no lip-readers are around.

The technology can also turn you into an instant polyglot. Because the electrical pulses are universal, they can be immediately transformed into the language of the user’s choice.

“Native speakers can silently utter a sentence in their language, and the receivers hear the translated sentence in their language. It appears as if the native speaker produced speech in a foreign language,” said Wand.

The translation technology works for languages like English, French and Gernan, but for languages like Chinese, where different tones can hold many different meanings, poses a problem, he added.

Noisy people in your office? Not any more. “We are also working on technology to be used in an office environment,” the KIT scientist told AFP.

The engineers have got the device working to 99 percent efficiency, so the mechanical voice at the other end of the phone gets one word in 100 wrong, explained Wand.

“But we’re working to overcome the remaining technical difficulties. In five, maybe ten years, this will be useable, everyday technology,” he said.

  10. maya says:

    thanks to da inventors ,u made great a contribution……….

  11. This is great technology. Can I ask one thing, does it work for any language used in lips movement or it works only for English conversation. Can we discuss to buy the device and technology to launch for sales.

  12. pavithracb says:

    It’s very nice to hear asilent sound technology.could u pls send the complete details about how it works screenshots,pdf files and related material
    hoping reply early

  13. Deepthi D says:

    Me and my colleague were discussing a solution for the very same problem that you are targeting. I was amazed and excited to c an article on the same. Eager to know how differently have u tackled this problem.l… Reading lip movement will not be that accurate as of what I know. We have a different approach to it…. Contact me on my mail ID so that we can discuss on the same
