Want to speak Spanish or German but can’t be bothered to spend the time learning the language ? Look no further. Researchers at the Carnegie Mellon University
in the United States have developed a device that detects movements in the neck and face when words are mouthed. The device detects the sounds that would be made if the words were actually spoken instead of mouthed, translates them into the target language and uses a voice synthesizer to say the translated words. The effect is that it can look like you are speaking another language (although in reality it looks like a dubbed movie).
