An audio navigation system including an artificial intelligence routing algorithm which does not require any internal or external sensors to locate the vehicle. The interface with the driver is via voice input and voice output and is therefor visually non-distracting and safe to use when the vehicle is in motion. The hardware is built around an optical disk player and therefor can be used for entertainment as well as navigation functions. Digitized maps, compressed voice records and the computer programs are stored on an optical disk.

A method of operating a speech-based data storage and processing system in order to produce navigation directions to assist travel from a starting location to a destination along a route consisting of a sequence of individually identifiable route segments selected from a plurality of route segments

A method of operating a speech-based data storage and processing system in order to produce navigation directions to assist travel from a starting location to a destination along a route consisting of a sequence of individually identifiable route segments selected from a plurality of route segments which occupy a geographic area and which intersect at nodes, comprising: storing map information, including information identifying the plurality of route segments, in an electrically accessible storage medium in the system; conducting a dialog with an individual in which the system issues audible spoken requests for identification of the starting location and of the destination and receives audible spoken responses from the individual; converting audible spoken responses from the individual into respective stored representations of the starting location and the destination as represented by the spoken responses; utilizing the stored representations to retrieve from the storage medium information identifying successive route segments forming a desired route between the starting location and the destination corresponding to the stored representations; and issuing successive audible spoken statements, each in response to an audible command spoken by the individual, each spoken statement describing a respective one of the successive route segments.
