[0004] First, when the driver of the vehicle says "open the window" by voice, the power window device opens the window. Along with this, the driver takes the ticket through the window and then speaks “close”, and the power window device closes the window. As described above, after the first speech such as "open the window", the object of the verb tends to be omitted when the speech is input later.

[0005] When the operating device is an audio device, for example, the phrase "turn up the volume" is used to raise the volume, and the phrase "more" or "turn up more" is used to further increase the volume. do. Accordingly, if a unique voice input corresponding to the type of the operating device is performed as described above, the operation by the voice input of the operating device can be performed by an ergonomic voice operation.

[0006] Therefore, an object of the present invention is to provide a voice operation system in which an operating device mounted on a vehicle is operated with a voice input corresponding to the type based on such a viewpoint.

[0007]

According to the first aspect of the present invention, a voice for operating at least one operating device (10, 20) mounted on a vehicle is input. At this time, voice recognition means (40, 50) for recognizing the input voice and converting it to a voice command, and object determination means (40, 50) for determining whether or not the voice command has an object representing the object of operation of the actuator. 110), storage means (130) for storing the object of the voice command and a verb for the object, and operating the operating device in response to the voice command based on the determination that the object exists by the object determination means. Control means (120) for controlling to cause
And a repetition command determining means (140) for determining whether or not the voice command is a repetition command based on the determination that there is no object by the object word determining means. There is provided a voice operation system for a vehicle operating device that repeats based on a determination of a repeat command by a determination unit.

According to this, the operation of the operating device is controlled by the control means in accordance with the flow of the voice command and the repetitive command. Therefore, the operation by voice input to the operating device can be performed with a unique human voice operation to the operating device. Therefore, the voice operation of the operating device can be performed more ergonomically.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an example in which a voice operation system according to the present invention is applied to a power window device 10 and an audio device 20 mounted on an automobile. This voice operation system includes an input switch 30, a microphone 40, and a voice recognition device 50. The input switch 30 is temporarily operated when voice is input by the microphone 40.

The microphone 40 receives a voice from the driver of the vehicle and receives the voice as voice data.
Output to 0. The voice recognition device 50 is a microphone 40
Is encoded and output to the microcomputer 70 as a voice command. The timer 60 outputs the time value as data to the microcomputer 70 based on the time measurement.

The microcomputer 70 executes the computer program according to the flowchart shown in FIG. 2, and during this execution, the power window device 1
0, perform arithmetic processing required for controlling the audio device 20 and the audio reproduction device 80. The computer program is stored in the ROM of the microcomputer 70 in advance.

[0015] In this embodiment configured as described above,
When the microcomputer 70 starts executing the computer program according to the flowchart shown in FIG. 2, in step 100, it is determined whether or not a voice command has been input from the voice recognition device 50. Here, if there is a voice command input, the determination in step 100 becomes YES.

The voice recognition device 50 outputs a voice command in response to a voice input to the microphone 40 under a temporary operation of the input switch 30. Timer 6
0 starts counting simultaneously with the start of execution of the computer program by the microcomputer 70. Next, in step 110, it is determined whether or not the voice command is in the form of a combination of an object and a verb.

If there is an object in the voice command, the determination in step 110 is YES. Accordingly, in step 120, processing corresponding to the voice command is performed. For example, if the voice command is a command of "open a window", a command process for opening a window of the vehicle by the power window device 10 is performed. Thereby, the power window device 10 opens the window based on the instruction processing for opening the window of the microcomputer 70.

If the voice command is a command to "turn up the volume", a command process for raising the volume of the audio device 20 is performed. Accordingly, the volume of the audio device 20 is increased. As a result, the volume of the audio device 20 increases. When the processing in step 120 is completed as described above, step 1
At 30, the object and verb of the voice command are stored, and the current time is stored based on the time output of the timer 60.

Thereafter, based on the voice command from the voice recognition device 50 again, the determination in step 100 is YE.
When S is reached, the determination in step 110 is made in the same manner as described above. Here, if there is no object in the voice command again, the determination in step 110 is NO. Then, in step 140, it is determined whether or not the above-mentioned voice command is a repeat command. Here, the repeated command means that the above-mentioned voice command is
A command that requires repetition without an object.

If the command is a repetition command, that is, if it is a voice command of "close" or "raise further", the determination in step 140 becomes YES. Then, in the next step 150, the object, verb and time stored in FIG. 130 are read. Accordingly, in step 180, it is determined whether or not the elapsed time corresponding to the difference between the time at the current stage and the time in step 130 is within a predetermined allowable time for the object.

For example, the predetermined allowable time is 30 seconds for the power window device 10 and 1 minute for the audio device 20.
0 in advance. Note that each of the above-mentioned predetermined allowable times may be appropriately changed. Therefore, step 15
If the data read at 0 corresponds to the power window device 10, it is determined whether or not the elapsed time is within 30 seconds. If the data read in step 150 corresponds to the audio device 20, it is determined whether the elapsed time is within one minute.

Here, the determination in step 180 is N
If the answer is O, error processing is performed in step 190. Specifically, a process is performed to the effect that the voice input is an error. For this reason, the audio reproducing device 80 notifies the user of the error by audio based on the error processing. Thereby, the driver can know that the voice input was an error.

On the other hand, the determination in step 180 is YE
If the answer is S, a command process is performed in step 120 according to the voice command again. For example, when the second voice command is “close”, the power window device 10 performs a command process to close the window. Accordingly, the power window device 1
0 closes the window.

If the second voice command is "raise further", a command process for further raising the volume of the audio device 20 is performed. Along with this,
The volume of the audio device 20 further increases. As described above, if the flow of the voice command is a flow of “open the window” and then “close” or a flow of “raise the volume” and then “raise the volume”, the power follows the flow. The window is opened and closed by the window device 10, or the volume of the audio device 20 is increased.

As a result, the power window device 10 and the audio device 20 can be operated by voice according to the unique flow of voice input to the power window device 10 and the audio device 20. That is, according to the flow of the voice command and its repetition command, the power window device 1
0 and the operation of the audio device 20 are controlled by the microcomputer 70. Therefore, the operation by the voice input to the power window device 10 or the audio device 20 can be performed by a unique human voice operation to the power window device 10 or the audio device 20. Therefore, voice operation of the power window device 10 and the audio device 20 can be performed more ergonomically.

The processing in step 130 is similarly performed on the above-mentioned voice command again. On the other hand, if the determination in step 140 is NO, in step 160, the object and the time are read from the data stored in step 130. Then, in step 161, the read object is supplemented by the second voice command.

Next, in step 170, it is determined whether or not the verb of the voice command again connects to the object meaningfully. Here, if the connection is not performed in a meaningful manner, the determination in step 170 is N
The result is O, and error processing in step 190 is performed. Along with this, the audio reproducing device 80 notifies the user that the second audio command is an error by voice.

Thus, the driver can know that there is an error in the voice input. Step 1
If the determination at 70 is YES, the process at step 180 is performed as described above. Thereafter, the processing of either step 180 or 190 is performed in the same manner as described above.

In implementing the present invention, the present invention is not limited to the power window device 10 and the audio device 20.
The present invention may be applied to various types of operating devices such as an air conditioner mounted on the vehicle and implemented. In practicing the present invention, the present invention may be applied to an operating device such as a power window device or an audio device generally mounted on a vehicle without being limited to an automobile.

In practicing the present invention, a display device such as a liquid crystal display device or other notification means may be employed in place of the audio reproduction circuit 80.
