Abstract

In a route guidance system, when depression of a PTT switch is detected in the middle of voice guidance of respective guidance landmarks located in a guidance route, recognition of a voice command inputted through a microphone is initiated, When the recognized voice command is identified as one of a next setting command and a return setting command, the voice guidance of the guidance landmarks is sequentially provided starting from a corresponding one of a previous guidance landmark and a next guidance landmark in consistency with the one of the next setting command and the return setting command. When the recognized voice command is other than the next setting command and the return setting command, setting and/or resetting of the guidance route are performed based on the type of the corresponding guidance landmark and the recognized command.
