Navigation device, navigation method, and navigation program

A navigation method that includes a step that a voice acquirer acquires an inputted voice, a step that a voice recognizer carries out a voice recognition process on voice data acquired by said voice acquirer, a step that a position acquirer acquires a position of a moving object, and a step that provides route guidance on a basis of a result of the recognition by said voice recognizer, the position of the moving object which is acquired by said position acquirer and map data, said method comprising:

• a step that a route guidance expression storage stores route guidance expressions;
• a step that a route guidance expression extractor refers to said route guidance expression storage to extract a route guidance expression from the result of the recognition by said voice recognizer;
• a step that a route guidance expression interpreter interprets the route guidance expression extracted by said route guidance expression extractor to determine a concrete route guidance expression;
• a step that a route guidance expression information to be presented storage stores visual information to be presented corresponding to said concrete route guidance expression while bringing the visual information to be presented into correspondence with said concrete route guidance expression;
• a step that a route guidance expression information to be presented retriever refers to said route guidance expression information to be presented storage to retrieve the corresponding visual information to be presented on a basis of the concrete route guidance expression determined by said route guidance expression interpreter;
• and
• a step that a presentation control outputter outputs the visual information to be presented retrieved by said route guidance expression information to be presented retriever.

A navigation program that provides route guidance on a basis of a result of recognition by a voice recognizer, a position of a moving object which is acquired by a position acquirer and map data by causing a computer to function as:

• a voice acquirer that acquires an inputted voice;
• said voice recognizer that carries out a voice recognition process on voice data acquired by said voice acquirer;
• a route guidance expression storage that stores route guidance expressions;
• a route guidance expression extractor that refers to said route guidance expression storage to extract a route guidance expression from the result of the recognition by said voice recognizer;
• a route guidance expression interpreter that interprets the route guidance expression extracted by said route guidance expression extractor to determine a concrete route guidance expression;
• a route guidance expression information to be presented storage that stores visual information to be presented corresponding to said concrete route guidance expression while bringing the visual information to be presented into correspondence with said concrete route guidance expression;
• a route guidance expression information to be presented retriever that refers to said route guidance expression information to be presented storage to retrieve the corresponding visual information to be presented on a basis of the concrete route guidance expression determined by said route guidance expression interpreter;
• and
• a presentation control outputter that outputs the visual information to be presented retrieved by said route guidance expression information to be presented retriever.
