Text-to-speech

Definition: Text-to-speech is a term describing the capability of converting digitized word text into machine-synthesized audible speech. This is a useful feature in GPS devices, because it provides precise audible directions. For example, a GPS unit without text-to-speech would announce an upcoming turn with the phrase "Turn right, 100 yards." A text-to-speech equipped GPS unit would announce the same direction as "Turn right, 100 yards onto West Elm Street."
