Next, referring to the flow charts of FIGS. 3 and 4 and the explanatory view of FIG. 5, the operation of registering an arbitrary point not displayed on the map as a memory point in the navigation apparatus of this embodiment will be described. To do. Figure 3
The memory point registration routine shown in FIG.
Press the menu switch of the switches 11b provided around the display 11a as shown in (a),
Next, the process starts when the spot registration key 52 is pressed on the menu screen 51 as shown in FIG. 5B or the spot registration mode is selected by voice input (step 101).

The user selects from among a plurality of methods of calling a detailed map such as a telephone number, an address, the vicinity of the current position, the vicinity of the destination, a golf course, and other facilities displayed on the selection screen in the spot registration mode. , A desired method is selected by touching with a finger or by voice input. Then, after selecting items on some list screens depending on the selected method, a detailed map is displayed on the display 11a according to the selected method. The user touches and selects a point to be registered as a memory point on this map. Then, the memory location registration screen 53 as shown in FIG. 5C is displayed on the display 11a and "Please touch the location number you want to register."
Is output from the voice output unit 17.

When the user touches the spot number to be registered, the general manager 37 registers the latitude and longitude coordinates of the memory spot in the memory spot register 18 (step 10).
2) At the same time, the display name of the memory point is registered (step 103). The display name of the memory point is, for example, "... prefecture ... city ... near town". At this time,
As shown in FIG. 5D, on the memory spot registration screen 53, the display name 54 of the memory spot is displayed at the position corresponding to the touched spot number. In addition, the display name of the memory point is registered (step 103) and the memory point registration screen 5 is displayed.
The display name 54 of the memory point in 3 may not be displayed.

Next, the arithmetic unit 10 executes a subroutine for voice registration of the memory location name (step 104), and then determines whether or not the user confirms the registration (step 105) and confirms. If there is (Y), the process returns to the main routine, and if there is no confirmation (N), the process returns to step 102, and waits for the user to touch a point to be registered again as a memory point.

FIG. 4 is a flow chart showing the operation in the subroutine (step 104) for voice registration of the memory location name in FIG. In this operation, first, as shown in FIG. 5 (e), the calculation unit 10 displays a message "Please say the word you want to register." Press the steering switch and say the words you want to register. "Is output from the voice output unit 17 (step 111). At this time, the voice registration stop key 55 is displayed on the memory location registration screen 53.
Is displayed.

Next, the arithmetic unit 10 uses the voice registration stop key 5
5 is pressed (step 112), and if not (N), it is determined whether the steering switch 40 has been pressed (step 113). If the steering switch 40 is pressed (Y), it is determined whether or not there is a voice input of an arbitrary point calling voice (step 114), and if there is a voice input (Y), the voice recognition unit 1
The characteristic parameters of the point calling voice extracted by the characteristic extraction unit 42 of No. 6 are temporarily stored in the personal data storage processing unit 44 (step 116). In addition, when the steering switch 40 is not pressed (step 113; N), the process returns to step 112, and when the point call voice is not input within a predetermined time after the steering switch 40 is pressed (step 114; N) outputs the voice message “Please again.” (Step 115) and returns to step 112.

After temporarily storing the characteristic parameters in step 116, the arithmetic unit 10 outputs a voice message saying "Register for the second time. Press the steering switch and say the words you want to register." ( Step 117). Next, the calculation unit 10 determines whether or not the voice registration stop key 55 is pressed (step 11).
8) If it is not pushed (N), it is judged whether or not the steering switch 40 is pushed (step 119).
If the steering switch 40 is pressed (Y), it is determined whether or not there is a voice input of an arbitrary point calling voice (step 120), and if there is a voice input (Y), the feature extraction of the voice recognition unit 16 is performed. It is determined whether or not the characteristic parameter of the point-calling voice extracted by the unit 42 matches the characteristic parameter temporarily stored in the personal data storage processing unit 44 at the time of the first voice input (step 121). In addition, when the steering switch 40 is not pressed (step 119; N) and when there is no voice input of the point calling voice within a predetermined time after the steering switch 40 is pressed (step 120; N), the step is performed. Return to 118.

When the characteristic parameters match (step 121; Y), the arithmetic unit 10 outputs a voice message "... (speech call voice) to register." The memory spot name represented by the parameter is registered in the memory spot registration unit 18 in association with the coordinates of the memory spot registered in step 102 of FIG. 3 (step 123). After that, the calculation unit 10 causes the display 11a to display the memory location confirmation screen 56 as shown in FIG. On the memory location confirmation screen 56, a voice registered mark 57 is displayed next to the display name 54 of the registered memory location, and a cancel key 58 is displayed. In addition, the location number registered by the user is touched, and the memory location registration unit 18
At the same time, the latitude and longitude coordinates of the point are registered, and at the same time, the display name of the registered memory point may be rewritten by the voice and displayed on the display 11a.

Next, the arithmetic unit 10 cancels the cancel key 58.
It is determined whether or not is pressed (step 124), and if the cancel key 58 is not pressed (N), the process returns to the memory point registration routine shown in FIG. If the cancel key 58 is pressed (Y), the process returns to step 111 and the voice registration is performed again. If the characteristic parameters do not match (step 121; N), a voice message "Please restart from the beginning" is output (step 122), the process returns to step 111, and voice registration is performed again.

When the voice registration stop key 55 is pressed (step 112; Y, step 118; Y), the arithmetic unit 10 outputs a voice message "Voice registration has been stopped" ( (Step 125) and the procedure returns to the memory point registration routine shown in FIG. In this case, as shown in FIG. 5 (g), the memory point confirmation screen 5
6, the voice registered mark 57 is not displayed.

After the execution of the voice registration subroutine of the memory point name, the memory point confirmation screen 56 as shown in FIG. 5 (f) or (g) is displayed on the display 11a, and the user can select this memory point. Registration is confirmed by touching the selected spot number on the confirmation screen 56.

Next, the operation of calling a memory point in the navigation device of this embodiment will be described with reference to the flowchart of FIG. In this operation, the user selects the destination setting mode by touching with a finger on the menu screen (step 201), and further selects the memory point mode by touching with a finger on the selection screen in the destination setting mode (step 202). )
Then, a state of waiting for voice input of the memory location name is entered (step 203). Here, when the voice input of the registered memory location name is made after the steering switch 40 is pressed (Y), the calculation unit 10 outputs the voice recognized by the voice recognition unit 16 from the voice output unit 17. An answer-back is performed (step 204), and the coordinates of the point corresponding to the voice-inputted memory point name are stored in the memory point registration unit 1
Read from 8 and display the map including the point 1
1a is displayed (step 205).

Next, waiting for confirmation of the point (step 20)
6) If there is a confirmation (Y), return to the main routine. If there is no confirmation (N), return to step 203,
Wait again for voice input of memory location name. Note that the point may be confirmed by, for example, a voice input of "confirmation" or by pressing a confirmation key displayed on the map. Also, step 20
If there is no voice input of the registered memory spot name in 3 (N), it is judged whether or not there is a touch selection on the list screen in the memory spot mode (step 207), and the touch selection is performed. If there is (Y), the process proceeds to step 205, and if there is no selection by touch (N), the process returns to step 201. Note that step 206
When the point is confirmed in step 3, the calculation unit 10 may recognize the point as the coordinates of the destination, search for a route from the current position to the destination, and immediately guide the route.

FIG. 7 is a flow chart showing another example of the operation of calling a memory point in the navigation device of this embodiment. In this example, the memory location mode is set by voice input. In this example,
When the user wants to set the memory point mode when the menu screen or the selection screen in the destination setting mode is displayed, the user inputs a voice for setting the memory point mode. The voice for setting the memory point mode is
For example, "memory point mode".

The arithmetic unit 10 first determines whether or not there is a voice input for setting the memory location mode (step 301). If there is a voice input (Y), for example, "Set memory point mode. Please check."
And outputs a voice message, and waits for the confirmation of the memory point mode setting by the user (step 302). The confirmation by the user is performed by voice input such as “confirmation”. If the memory spot mode setting is confirmed (Y), the state of waiting for voice input of the memory spot name is set (step 303).

Here, when the voice input of the registered memory spot name is made after the steering switch 40 is pressed (Y), the arithmetic unit 10 outputs the voice recognized by the voice recognition unit 16 to the voice output unit 17. The answer point is output (step 304) and the coordinates of the point corresponding to the voice-inputted memory point name are stored in the memory point registration unit 18.
We read from and display map including the point 11
It is displayed in a (step 305). Next, the confirmation of the spot is waited (step 306), and if there is confirmation (Y), the process returns to the main routine. If there is no confirmation (N), the process returns to step 303 and waits again for voice input of the memory location name.

If there is no voice input for setting the memory point mode in step 301 (N), it is judged whether or not the memory point mode has been selected by touching on the screen (step 307). If yes (Y), go to step 303, and if there is no selection (N)
Returns to step 301. In step 303, if there is no voice input of the registered memory spot name (N), it is determined whether or not there is a selection by touch on the list screen in the memory spot mode (step 3
08), if there is a touch selection (Y), the process proceeds to step 305, and if there is no touch selection (N), the process returns to step 301. When the point is confirmed in step 306, the arithmetic unit 10 recognizes the point as the coordinates of the destination, searches for a route from the current position to the destination, and immediately guides the route. Is also good.

Although the voice registration of the memory spot name is performed in the spot registration mode in the above embodiment, the spot is also selected in other operations such as inputting the destination and inputting the current position. The name of the selected point may be registered by voice by executing the operation as shown in FIG. 4 later. Also, after voice registration of the name of the point, not only when inputting the destination but also when inputting the current position,
The operation as shown in FIG. 6 or 7 may be executed to input the memory location name by voice so that the current location can be input. In addition, the names of points (home, company, etc.) that are likely to be registered in advance are the voice recognition dictionary 4
By registering in advance in the unspecified speaker dictionary out of 3, it is possible to call the memory point by voice input of the memory point name without voice registration of the memory point name if only the point is registered. Becomes

In the above embodiment, the coordinate of the registered point is registered in association with the point calling voice. However, the coordinate in the map including the registered point (for example, the coordinate of the upper left corner of the map). ) Is registered in association with the voice for point calling, and when the voice input of the memory point name is performed, the map including the registered point is displayed based on the coordinates in the registered map. You can

As described above, according to the above-mentioned embodiment or its modification, it is possible to select a mode or a spot by voice input, so that the operation of selecting a spot in setting the current position or destination can be performed. It can be simplified and the operation time can be shortened. Further, since the point can be selected by voice input, the operation during driving becomes possible. In addition, in the destination setting mode, the point selected by voice input is set as the destination, and the route from the current position to the destination is searched and the route guidance is provided to maintain the eyes-free state. , Can improve safety more. In addition, for example, when registering a home as a memory point, an arbitrary memory point name such as “return” can be registered, so that the operation is easy to remember.

[0039]

As described above, according to the navigation device of the first aspect, the correspondence between the coordinates of the selected point or the coordinates in the map including the selected point and the arbitrary point calling voice is determined. Since the map including the point corresponding to the point-calling voice is displayed on the display by using the stored correspondence when the point-calling voice is stored and stored, the map of the current position and the destination is displayed. It is possible to simplify the operation of selecting a point in setting and the like, and also to perform the operation during driving. Further, according to the navigation device of claim 2, when the point calling voice is input to set the destination, the coordinates of the point corresponding to the point calling voice are stored using the stored correspondence. Is recognized as the coordinates of the destination and the route from the current position to the destination is searched for. Therefore, in addition to the above effects, the operation up to the start of the route search can be further simplified.
