1. Navigation apparatus for use within a vehicle, the apparatus comprising:
- recognition means mounted within the vehicle for recognizing a voice signal, said recognition means includinga directional microphone constructed and mounted to detect speech preferentially from a user of the apparatus situated at a predetermined location within the vehicle, said predetermined location being selected from the group consisting of a plurality of locations within the vehicle;
a voice recognition data memory for storing character data including place names, operation commands, and information relating to frequently mistaken place names, for allowing said recognition means to match said voice signal with said character data; and
a conversion data memory for storing longitude/latitude data and incidental data including display scale data corresponding to each place name stored in said voice recognition data memory,display means for displaying a map of at least one of said place names in a predetermined display scale, androute search means for setting a predetermined position in said map being displayed as a destination point in response to a predetermined operation by the user or a recognized signal that is matched with one of said place names stored in said voice recognition data memory and converted to lonqitude/latitude data and incidental data stored in said conversion data memory, and for searching for a route on said map to said destination point,wherein said voice signal recognized by said recognition means includes a navigational command or one of said operation commands.

5. A method of navigating a vehicle, the method comprising:
-
a recognition step for preferentially recognizing a voice of a user situated at a predetermined location within the vehicle, said predetermined location being selected from the group consisting of a plurality of locations within the vehicle, a matching step for matching said voice with character data stored in a voice recognition data memory, said character data including place names, operation commands, and information relating to frequently mistaken place names, a converting step for converting said place names into longitude/latitude data and incidental data including display scale data by looking said place names up in a conversion data memory, a display step for displaying a map of at least one of said place names in a predetermined display scale, a setting step for setting a predetermined position in the displayed map as a destination point in response to a predetermined operation by the user or in response to the recognized voice that is matched with one of said place names stored in said voice recognition data memory and converted to longitude/latitude data and incidental data stored in said conversion data memory, and a searching step for searching for a route on said map to said destination point, wherein said voice recognized in said recognition step includes a navigational command or one of said operation commands. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A car with a navigation apparatus comprising:
-
directional microphone means constructed and mounted inside said car to detect preferentially speech of a user of the apparatus situated at a predetermined location within the car, said predetermined location being selected from the group consisting of a plurality of locations within the car, recognition means for recognizing a voice detected by said microphone means, said recognition means including a voice recognition data memory for storing character data including place names, operation commands, and information relating to frequently mistaken place names, for allowing said recognition means to match said voice with said character data; and a conversion data memory for storing longitude/latitude data and incidental data including display scale data corresponding to each place name stored in said voice recognition data memory; display means located inside said car for displaying a map of at least one of said place names in a predetermined display scale, and route search means for setting a predetermined position as a destination point in said map being displayed in response to a predetermined operation by the user or a voice detected by said microphone means that is matched with one of said place names stored in said voice recognition data memory and converted to longitude/latitude data and incidental data stored in said conversion data memory, and for searching for a route to said destination point, wherein said voice recognized by said recognition means includes a navigational command or one of said operation commands. - View Dependent Claims (13, 14, 15)
