Voice Overview
Equipped with speech recognition and text-to-speech technology, Street Atlas USA 2005 lets you issue a series of
voice commands to a laptop computer. The voice commands activate basic navigation, map control, and GPS
features, providing you with hands-free program navigation so you can concentrate on your driving. When tracking
with a GPS receiver, you can receive spoken updates about your route directions, next turn, next stop, current
location, etc.
