Enhanced speech recognition accuracy is provided by using geographic data, illustratively related to the geographic location of a mobile device, to automatically select a subset of words for use with a speech recognition procedure. The subset of words is selected from an element database including words that describe elements at each of a plurality of locations. Geographic data includes at least one of global positioning system (GPS) position data, cell identity (Cell-ID) data, caller identification (Caller ID) data, place name data, or zip code data. Elements include at least one of street names, businesses, merchants, points of interest, transportation facilities, individual households, activities, and landmarks. By selecting a subset of words, the total number of words used in the speech recognition procedure is substantially reduced, thereby improving speech recognition accuracy.
