subvocal speech recognition
Technology never stops to amaze me. Something totally unexpected comes from NASA. Speaking something without opening your mouth. Just talking to yourself and the computer will recognize it?! Its really close to telepathy but not quite brain reading yet. Basically you have a sensor on your chin close to your Adamīs aple and it recognizes your nerves firing off before you even move your tongue or your mouth. This will really help speech recognition in noisy unstable environments but also has great applications of silent communication. Now you can sit in a restaurant and its totally silent and still everyone is talking to each other - really stuff from a sci-fi movie.
