PROBLEM TO BE SOLVED: To properly and quickly recognize hierarchical data at the speech recognition of the data, even when non-upper level hierarchical data is entered. SOLUTION: When a user vocally enters the intermediate hierarchical data and the low-level hierarchical data of hierarchical structure data (Yes at S13), the entered intermediate hierarchical data and the low-level hierarchical data are held, and a guide is vocally made for entering upper-level hierarchical data at S15. As a result, the user comes to vocally enter the upper-level hierarchical data. Thus, hierarchical data is determined on the basis of the vocally entered upper-level hierarchical data, the stored intermediate hierarchical data and the low-level hierarchical data, and a corresponding map can be shown on the screen of a display at S7. |
