Cell Phones that Can Read Lips

Researchers in Germany are trying to develop a cell phone that can read lips by measuring the electrical activity used in the muscles of the mouth while speaking, which is then converted into a computer-simulated voice:

The user can speak into the phone soundlessly, but is still understood by the conversation partner on the other end of the line. As a result, it is possible to communicate in silent environments, at the cinema or theater, without disturbing others. Another field of use is the transmission of confidential information.

For the transmission of passwords and PINs, for example, users can change seamlessly to soundless language and, hence, transmit confidential information in a tap-proof manner.
