Abstract: The present invention relates to a voice recognizing navigation device and a method thereof. The navigation device according to one embodiment of the present invention includes a voice inputting unit in which audio signals are inputted; a voice recognizing-analyzing unit which extracts voice information from the audio signals, separates the voice information into command information and search word information, and recognizes the separated information; a spot search unit which produces search result information corresponding POI information or address information based on the recognized command information and the search word information; and an output unit outputting the search result information. [Reference numerals] (S201) Recognize inputted audio signal;(S220) Extract voice information from the recognized audio signal;(S230) Divide command information and search word information about extracted voice information;(S240) Compare divided command information to stored command information stored in command database;(S250) As a comparison result, judge that command information is in the first command group defining within range of preset distance from current location;(S255) As a judgment result, when the command information is in the first command group defining within range of preset distance from current location, search whether or not being included in interest location information corresponding to search word information within preset distance from current location or stored search word information stored in search word information database;(S260) As a comparison result, judge that command information is in the second command group defining within range of preset distance from command information guided path;(S265) As a judgment result, when the command information is in the second command group defining within range of preset distance from command information guided path, search whether or not being included in interest location information corresponding to search word information within preset distance from guided path or stored search word information stored in search word information database;(S270) As a comparison result, judge that command information is in the third command group defining administrative district including current location;(S275) As a judgment result, when the command information is in the third command group defining administrative district including current location, search whether or not being included in interest location information including current location or search word information within preset distance from guided path or stored search word information stored in search word information database;(S280) As a comparison result, judge that command information is in the fourth command group including the name of administrative district defining address information;(S285) As a judgment result, when the command information is in the fourth command group including the name of administrative district defining address information, search whether or not being included in interest location information included in the name of administrative district or stored search word information stored in search word information database;(S290) As a comparison result, when the command information is not identical to stored command information stored in command database, recognize command information as search word information and search whether or not being included in stored search word information stored in search word information database;(S295) Output search result information
