Description

  The present invention relates to a car navigation device and a program for a car navigation device, and more particularly to a car navigation device and a program for a car navigation device that can be operated by voice using voice recognition technology.

  In recent years, systems capable of interactive operation using voice recognition technology have been widely used in car navigation systems and the like. However, when the voice input is not recognized, only a re-utterance request is made, and the operation requested by the user is not executed.

  Therefore, a vehicular voice recognition device that enables manual operation when voice input is not recognized is known (for example, see Patent Document 1).

  In this vehicular voice recognition apparatus, an instruction to switch to manual operation is issued when voice input is not recognized. The user presses a separately provided switch and inputs a command determined according to the number of times the switch is pressed, thereby executing the corresponding command.

  However, the conventional vehicular voice recognition device needs to set the number of times the switch is pressed for all commands executed by voice recognition. When various commands can be executed by voice recognition, setting the number of times corresponding to each command and inputting the command by operating the switch is the same as performing a normal navigation operation, There is a problem that commands cannot be input efficiently.

  The present invention has been made to solve the above-described problem, and a car navigation device and a car navigation device that can efficiently input a command even when the command corresponding to the voice recognition result cannot be executed. The purpose is to provide a program.

  In order to achieve the above object, the car navigation device of the present invention is capable of displaying a command input button, and a display means provided with a touch panel for inputting a command corresponding to the operation of the displayed button, When the command corresponding to the voice recognition result of the voice recognition means and the processing means for executing the command input from the touch panel and the command corresponding to the voice recognition result cannot be executed, the execution frequency And a control means for controlling the display means so that a button for inputting a high command is displayed.

  The car navigation device program of the present invention can display a command corresponding to the voice recognition result of the voice recognition means and a command input button on the computer, and a command corresponding to the operation of the displayed button. High frequency of execution when the processing means for executing the command input from the touch panel of the display means provided with the touch panel for input and the command corresponding to the voice recognition result cannot be executed It functions as a control means for controlling the display means so that a button for inputting a command is displayed.

  According to the car navigation apparatus of the present invention and the program for a car navigation apparatus of the present invention, the processing means performs a process of executing a command corresponding to the voice recognition result and a command input from the touch panel. When the processing unit cannot execute a command corresponding to the voice recognition result, the control unit controls the display unit to display a button for inputting a command having a high execution frequency. Thereby, it becomes possible to input a command from the touch panel by operating the button displayed on the display means, and even when a command corresponding to the voice recognition result cannot be executed, Can be executed.

  The processing means of the present invention can perform processing for updating the execution frequency of the executed command when processing for executing the command is performed.

  Further, the control means of the present invention displays a button for inputting the frequently executed command when the voice recognition result is unrecognized and when there is no command corresponding to the voice recognition result. Thus, the display means can be controlled.

  In addition, the control unit can control the user to make another utterance request when controlling the display unit so that a button for inputting a frequently executed command is displayed. . Thereby, a command can be input also by speaking again.

  As described above, according to the present invention, when a command corresponding to the voice recognition result cannot be executed, a button for inputting a frequently executed command is displayed on the display means. By operating the button displayed via the command, an effect that a command can be input is obtained.

  Hereinafter, a car navigation device 10 according to an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the present embodiment recognizes a voice input from the voice input device 20 using a voice input device 20 composed of a microphone or the like for inputting voice and a voice recognition database 22. A voice recognition device 24 is provided.

  The voice recognition device 24 is connected to a control device 26 composed of a microcomputer. The control device 26 includes a CPU, a ROM, and a RAM, and a processing routine program described below is stored in the ROM as a storage medium.

  The control device 26 includes a command execution frequency memory 28 provided with a plurality of commands and an execution frequency storage area provided corresponding to each of the commands, a map information database 29 storing map information, and a command input The touch panel display 30 provided with a touch panel for inputting a command corresponding to the operation of the displayed button and a plurality of other sensors such as a GPS receiver and a vehicle speed sensor. 32 is connected.

  The control device 26 is connected to a speaker 34 for emitting sound toward a driver who is a user.

  Hereinafter, the processing routine of the present embodiment will be described with reference to FIG. In step 100, it is determined whether or not a voice recognition result is input from the voice recognition device 24. If a voice recognition result is input, the command execution frequency memory is based on the voice recognition result input in step 102. The command stored in 28 is searched.

  In the next step 104, it is determined whether or not the command has been searched. If the command has been searched, the command for the executed command is executed in step 114 after executing the searched command in step 112. The execution frequency stored in the execution frequency memory 28 is updated so as to increase. For example, if the voice recognition result is “traffic information”, the “traffic information” command is searched from the commands stored in the command execution frequency memory 28, and processing for displaying the traffic information is executed. Thereafter, the “traffic information” command stored in the command execution frequency memory 28 is updated so that the execution frequency is increased.

  On the other hand, if the command cannot be searched because the voice recognition result is unrecognized, or if the voice recognition is normally recognized but the corresponding command is not searched, it is determined in step 104 that the command cannot be searched. In step 106, a sound for requesting voice utterance again is emitted from the speaker 34 toward the driver, and a plurality of commands are read from the command execution frequency memory 28 in descending order of execution frequency, and a button for inputting the read commands 40 is displayed on the display 30.

  If the normal screen as shown in FIG. 3 is displayed before the voice utterance, the screen shown in FIG.

  FIG. 4 shows a button 40 for inputting a command for displaying traffic information on the display as a button 40 for inputting a command having a high execution frequency by the processing of step 106, and a peripheral facility. A button labeled “Nearby facility” for entering a command to display an icon or the like to be displayed on the display, “News” to enter a command for displaying news on the display or emitting sound from the speaker Button for entering the command to display what day is today on the display, and the button to display the destination setting screen on the display. This shows a state where a button labeled “Destination setting” is displayed on the display. In FIG. 4, for example, the speech utterance was “traffic information”, but the speech recognition result is unrecognized due to unclear pronunciation or noise, or the speech recognition result is “near convenience store”. And shows a display when the corresponding command is not found.

  In the next step 108, it is determined whether or not a speech recognition result that is uttered in response to the re-utterance request in step 106 and is recognized by the speech recognition device 24 is input. Returning to 102, the processing described above is executed.

  On the other hand, if no voice recognition result is input, it is determined in step 110 whether or not any of the buttons 40 for inputting a command with a high execution frequency displayed on the display 30 has been operated. When the button is operated, the command corresponding to the button operated in step 112 is executed, and the execution frequency of the command executed in step 114 is updated. For example, when “traffic information” is spoken and the voice is not recognized and displayed as shown in FIG. 4, the command is input by operating the “traffic information” button from the displayed command input button. do it. In addition, when the voice recognition result is “Nearby convenience store” and the corresponding command is not found, the command “Nearby facility” is a command suitable for searching for a nearby convenience store from the displayed command input buttons. The command can be input by operating the "" button.

  If it is determined in step 110 that the button has not been operated, it is determined in step 108 whether or not a voice recognition result has been input, and determination of input of the voice recognition result and determination of whether or not the button has been operated. And repeat. If there is no voice input or button operation for a predetermined time, this routine is terminated.

  As described above, in the present embodiment, when a command cannot be searched, a request for reoccurrence and a button for inputting a command having a high execution frequency are displayed, so that the command cannot be searched. Command can be input efficiently.

  In the above embodiment, when a command search is not possible, an example in which a request for recurrence is displayed and a button for inputting a command with high execution frequency has been described. However, a command with high execution frequency is input. It is also possible to display only a button for doing so.

  Also, when a button for inputting a command with high execution frequency is displayed, it is only necessary to display a button for inputting a command with high execution frequency. There is no need to update the frequency of command execution. For example, when a button for inputting a command having a high execution frequency is displayed, the command with a high execution frequency set in a usage status survey or the like may be displayed every time.
