<P>PROBLEM TO BE SOLVED: To perform voice guidance even when character voice data includes a lack. <P>SOLUTION: The navigation system includes a standard voice data storage means and a character voice data storage means. Standard unit voice data and character unit voice data include voice data storage means 317 accumulated in association with an identifier, respectively. Guidance route data includes the identifier information of unit voice data for outputting a guidance voice at a guidance point for each guidance point. When guidance voice output by character voice data is selected, a voice data lack discriminating means 214 discriminates the presence and absence of a lack in the character unit voice data at a guidance point on the basis of guidance route data including an identifier. When there is a lack, a character voice data edit means 220 edits the guidance route data on the basis of only the character unit voice data, and a voice guidance output means 221 performs voice output on the basis of the edited guidance route data. <P>COPYRIGHT: (C)2010,JPO&INPIT |
