when we are in movie, theatre, bus, train there is lot of noise around us we can’t speak properly on a mobile phone. In future this problem is eliminated with the help of Silent sound technology. It is a technology that helps you to transmit information without using your vocal cords. This technology notices every lip movements & transforms them into a computer generated sound that can be transmitted over a phone. Hence person on another end of phone receives the information in audio This device is developed by the Karlsruhe Institute of Technology (KIT).It 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 .When demonstrated, it seems to detect every lip movement and internally converts the electrical pulses into sounds signals and sends them neglecting all other surrounding noise. So, basically, it reads your lips. It is definitely going to be a good solution for those feeling annoyed when other speak loud over phone.
