DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a navigation device of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of the navigation device of the present invention. In FIG. 1, the navigation device includes a navigation device body 11 that calculates and displays its own absolute position, an infrared remote controller 12 that remotely controls the navigation device body 11, and a voice control device 13 that remotely controls the navigation device body 11. It is roughly composed of.

The navigation device main body 11 receives positioning radio waves from three or more GPS satellites in the sky and outputs demodulated data subjected to spectrum despreading processing G
The absolute position (two-dimensional position of latitude and longitude or three-dimensional position of latitude, longitude and altitude), which is the reception position, is calculated based on the PS receiver 11a and the demodulated data, and manual operation and remote operation (infrared remote A control unit 11b is provided that controls the display as well as the operation on the controller 12) and the voice operation (the operation of the voice control device 13). Further, the navigation device main body 11 is provided with a relative position detection sensor 11c, a map information storage unit 11d, and a manual operation unit 11e for performing an operation operation, for example, an operation start instruction and a display map change instruction. . Further, a display unit 1 such as a CRT or LCD for displaying a map and a self-position on the screen.
1f and the light-receiving part 11g which receives the command (infrared) of the infrared remote controller 12 are provided.

The infrared remote controller 12 has a light emitting section 12 for sending a command (infrared ray) to the light receiving section 11g.
a, an operation unit 12b including a keyboard for performing various input operations, and a control unit 12 that generates a command corresponding to an input from the operation unit 12b and sends the command to the light emitting unit 12a.
c is provided.

The voice control device 13 recognizes, for example, a microphone 13a to which voices for various operations from an operator are input, a voice signal from the microphone 13a, and a synthesized voice signal and a recognition result. A voice synthesis recognition unit 13b that outputs a signal is provided. Further, based on the recognition result signal from the voice synthesis recognition unit 13b, the remote control unit 13c that sends the same operation signal as the operation of the operation unit 12b of the infrared remote controller 12 and the operation signal from the remote control unit 13c are transmitted as infrared rays. A remote controller signal synthesizer 13d for outputting to the controller 12c of the remote controller 12 is provided.

Next, the operation of this embodiment will be described. FIG. 2 is a diagram for explaining the operation operation and its operating state, and FIG. 3 is a diagram for explaining the hierarchical contents of the voice recognition dictionary. 1 to 3, the operator speaks a "menu" to start the operation. The voice signal of this utterance is transmitted from the microphone 13a to the voice synthesis recognition unit 13
Input to b (step (denoted as S in the figure)
1). The voice synthesis recognition unit 13b outputs the voice of "menu" from the speaker 13e, and notifies the operator (operator) of the voice recognition result (steps 2 and 3). Furthermore, the voice recognition result signal (menu) from the voice synthesis recognition unit 13b is input to the remote control unit 13c. The remote control unit 13c sends the same operation signal as the operation of the operation unit 12b of the infrared remote controller 12 to the remote controller signal synthesis unit 13d based on the recognition result signal from the voice synthesis recognition unit 13b. The operation signal from the remote controller signal synthesis unit 13d is output to the control unit 12c of the infrared remote controller 12 (step 4,
5). The command converted into the voice recognition result signal (menu) by the control of the control unit 12c is transmitted to the light receiving unit 11g of the navigation device body 11 (step 6). The reception signal from the light receiving unit 11g is captured by the control unit 11b of the navigation device body 11.
By analyzing this received signal, the instruction uttered by the operator
The menu screen is displayed on the display unit 11f by identifying that it is a “menu” display instruction (step 7). This screen information is output to the remote control unit 13c in the voice control device 13 (step 8), and further, voice is output from the speaker 13e through the remote control unit 13c and the voice synthesis recognition unit 13b. This voice output is, for example, "You can ... on this screen" (steps 9 and 1).
0). At the same time, the control unit 11b performs processing to make the recognition dictionary storing the vocabulary for operating the menu screen with the map information storage unit 11d the dictionary used for the next recognition process.
Further, under the control of the control unit 11b of the navigation device body 11, the screen type information and the cursor position information on the screen are sent to the remote control unit 13c in the voice control device 13. Next, when the operator utters "route guidance" which is one of the functions that can be selected from the menu screen, the voice signal of this utterance is input from the microphone 13a to the voice synthesis recognition unit 13b (step 11). The voice synthesis recognition unit 13b outputs the utterance of "route guidance" from the speaker 13e to notify the operator (operator) of the voice recognition result (steps 12 and 13). Furthermore, the speech synthesis recognition unit 13
The voice recognition result signal (route guidance) from b is input to the remote controller 13c (step 14). At the same time, the control unit 11b performs processing with the map information storage unit 11d to make the recognition dictionary storing the vocabulary for operating the route guidance screen the dictionary used for the next recognition process. Remote control unit 1
When instructing the route guidance, 3c determines the number of times the cursor is moved and sends the same operation signal as the operation of the operation unit 12b of the infrared remote controller 12 to the remote controller signal synthesis unit 13d (step 15). An operation signal (route guidance) from the remote controller signal synthesis unit 13d is output to the control unit 12c of the infrared remote controller 12. A command corresponding to the voice recognition result signal (route guidance) is transmitted from the light emitting unit 12a to the light receiving unit 11g of the navigation device body 11 under the control of the control unit 12c (step 16). The received signal from the light receiving unit 11g is the control unit 1 of the navigation device body 11.
It is taken in by 1b. This received signal is analyzed to identify that the instruction uttered by the operator is a “route guidance” selection instruction, and the route guidance menu is displayed on the display unit 11.
The screen is displayed by f (step 17). This screen information is output to the remote control unit 13c in the voice control device 13 (step 18). From this point onward, the operator is notified of this selection process by voice, as in the case of the previous "menu" process.

As described above, the contents of the dictionary hierarchy for voice recognition are changed as shown in FIG. 3 according to the operation instruction by the operator's voice. In the case of using, for example, the initial dictionary 31 in FIG. 3, the dictionary 3 in which the menu screen described above can be operated.
Although 2 is used, even if the dictionary 33 is loaded by mistake in the recognition processing, if the dictionary 33 has a menu as a vocabulary, the recognition processing can be performed if the operator utters "menu" again. In addition, since it is found that the word is one level before, it is possible to reload the instruction 33 without proceeding to the third level and to enable the operation on the menu screen. With this processing, the dictionary becomes larger as it goes to the lower hierarchy, but with the exception that it is not returned to the second hierarchy, the n-layer dictionary has n-1 hierarchical vocabulary. Including, but n
-It is not necessary to include the vocabulary before the second hierarchy. Exceptions in this case are words that display a map of the current location and some words that are highly urgent, such as words that return to the initial screen.

As described above, in this embodiment, the voice recognition result is obtained by the input operation by the operator and the utterance of the place name and the like.
The following operation contents can be confirmed by synthesized voice. Further, in the case of erroneous recognition, it can be corrected by re-speaking the voice, so that the operation can be performed while driving, which contributes to safe driving.

In this embodiment, the screen is displayed on the display unit 11f, and the voice control device 13 makes the selection by the voice of the operator. However, the screen display is not performed on the display unit 11f. The operation may be performed by the voice of the operator.

[0022]

As is clear from the above description, according to the navigation device of the first to third aspects, the self-position display means is placed in the operating state based on the voice recognition result uttered by the operator for the operating operation. Since it is configured to be controlled by remote control of the remote control device, it is possible to easily perform operation instructions by voice and correction thereof, for example, there is an effect that the operation operation can be easily performed even in a narrow vehicle or while driving. .
