FIG. 2 is a diagram for explaining an operation operation by voice recognition and its operation state. In FIG. 2, a case where the operation operation of “route guidance” corresponding to the operation button of the remote controller 11 is set by voice recognition will be described here.

Since the operator starts this operation operation,
While turning on the voice input switch 36, a "menu" corresponding to the operation button of the remote controller 11 is uttered. The voice signal of this utterance is input from the microphone 31 to the voice recognition synthesis unit 32. The voice recognition synthesis unit 32 outputs the voice of "menu" from the speaker 35,
The operator (operator) is notified of the voice recognition result. further,
The voice recognition result signal (menu) from the voice recognition synthesis unit 32 is input to the control unit 33. The control unit 33 sends the same operation signal as the operation on the remote controller 11 to the remote signal generation unit 34 based on the recognition result signal from the voice recognition synthesis unit 32. The operation signal from the remote signal generation unit 34 is output to the light reception / light emission signal processing unit 28 in the navigation main body device 10. An operation signal obtained by converting the same command as the operation on the remote controller 11 is output from the light reception / light emission signal processing unit 28 to the calculation / control unit 23. The calculation / control unit 23 analyzes the received operation signal, identifies that the instruction uttered by the operator is a “menu” display instruction, and displays the menu screen on the display unit 2
The screen is displayed at 5. This screen information is the voice operation control unit 12
Voice is output from the speaker 35 through the control unit 33 and the voice recognition / synthesis unit 32. This voice output is, for example, "... can be done on this screen". That is, the selectable function is notified by voice. Further, under the control of the calculation / control unit 23 in the navigation main body device 10, the information of the screen type and the information of the cursor position on the screen displayed on the display unit 25 is used as the control unit 33 in the voice operation control unit 12. Sent to.

Next, when the operator utters "route guidance" corresponding to the operation button of the remote controller 11 while turning on the voice input switch 36, which is one of the functions that the operator can select from the menu screen on the display unit 25. , The voice signal of this utterance is output from the microphone 31 to the voice recognition and synthesis unit 3.
Entered in 2. The voice recognition synthesizer 32 is "route guidance"
Is output from the speaker 35 to notify the operator of the voice recognition result. Further, the voice recognition result signal (route guidance) from the voice recognition synthesis unit 32 is input to the control unit 33. When instructing route guidance, the control unit 33 determines the number of times the cursor is moved, and the remote controller 11
The same operation signal as the operation in step 1 is sent to the remote signal generator 34. The operation signal (route guidance) from the remote signal generation unit 34 is input to the light reception / light emission signal processing unit 28 in the navigation main body device 10. An operation signal obtained by converting the same command as the operation on the remote controller 11 from the light reception / light emission signal processing unit 28 is calculated / control unit 2
3 is output. After that, the operation signal captured by the calculation / control unit 23 is analyzed, and the instruction uttered by the operator is
The instruction for "route guidance" is identified, and the route guidance screen is displayed on the display unit 25. Thereafter, the same processing as in the case of the above-mentioned "menu" utterance is performed.

As described above, the operation of the remote controller 11 is performed by turning on the voice input switch 36 and uttering a voice corresponding to the operation button of the remote controller 11, instead of operating the operation setting of the remote controller 11. The same operation as the setting is performed.

Next, a case where the operation by the voice recognition is simplified will be described. In this case, the operation signal determination unit 301 shown in FIG. 3 for distinguishing the operation signals from the remote controller 11 and the voice operation control unit 12 is added to the forefront. An operation signal from the remote controller 11 including the operation signal determination unit 301 or the voice operation control unit 12 is calculated / calculated through the light reception / light emission signal processing unit 28.
It is taken in by the control unit 23. The calculation / control unit 23 checks the operation signal determination unit 301 at the front of the received operation signal to determine whether the operation signal is from the remote controller 11 or the voice operation control unit 12. And from the remote controller 11, that is,
When the operation signal determination unit 301 is not added to the head of the operation signal, normal operation setting is performed, and when the voice operation control unit 12 is used, that is, the operation signal determination unit 301 is added to the head of the operation signal. If so, the operation control is performed only for the necessary operation settings, and the number of operation controls is reduced.

For example, an operation signal when the operator utters a "menu" while turning on the voice input switch 36 is taken in by the light reception / light emission signal processing unit 28 in the navigation main unit 10 and the operation signal at the head thereof is taken in. Judgment unit 30
When it is determined by 1 that it is from the voice operation control unit 12, the necessary place name search is performed without displaying the menu screen. That is, the place name search screen, which is a sub screen of the menu screen, is displayed. Further, although the map and the cursor are displayed after the map is determined, the movement of the cursor is advanced more than the step of the remote controller 11. For example, when operating the remote controller 11, the cursor is advanced every other step, but in operation setting by voice recognition, the cursor is advanced every five steps.
In the case of the operation setting by voice recognition, the operation setting operation is performed without visually observing the display screen of the display unit 25. Therefore, the movement amount of the cursor is increased and the operability is facilitated.

By distinguishing the operation signal determination unit 301 shown in FIG. 3 provided at the forefront of the operation signals from the remote controller 11 and the voice operation control unit 12, the voice input switch 36 is not turned on. You can also
