PURPOSE:To prevent the processing speed and precision of speech recognition from deteriorating when a vocalized place name is recognized and a map corresponding to the place name is displayed. CONSTITUTION:Place names are made hierarchical corresponding to the scales of maps and, for example, when a map of an area corresponding to a place name 'KANTO' belonging to a layer of a 1:1000,000 scale is displayed, the meaning of the word as an object of speech recognition is limited to the place names belonging to layers of a 1:10,000,000 scale, a 1:1,000,000 scale, a 1:100,000 scale, and a l:25,000 scale in specific relation with the layer that the place name 'KANTO' belongs to. |
