PROBLEM TO BE SOLVED: To increase the use of vocal command input. SOLUTION: When commands which can be inputted in voice are manually inputted through a switch device, etc., those commands can be recognized by using a voice recognizing function, so a user is informed (taught) that vocal command input is possible. For example, an adaptive screen and commands are displayed on the display screen of a display device 5. When a menu screen is displayed by, for example, manual input operation, 'Vocal input is available. Speak to a menu screen on a map screen.' is displayed. For a vocal guide, on the other hand, the same contents are spoken through a speaker 11. With this guide, the user is greatly expected to employ an easy command input method by the vocal input instead of an input method such as manual input which is considered to require relatively troublesome operation. |
