For years Microsoft has been investing in many forms of natural input in order to simplify the way people interact with their PC's and devices. The advent of the original Windows graphical user interface forever changed the way people used their PC's.

Speech recognition, something which was once considered science fiction, is enabling many Windows Vista users to see, hear, and use their computers for the very first time.
