Alternatively, all or part of the above-described functional elements included in the 1 st processor 50 may be configured by hardware including one or more electronic circuit components.
The recording unit 65a acquires the voice acquired by the microphone 9 via the IVI6 and records the voice. Specifically, the recording unit 65a stores the acquired voice data in the 1 st memory 51. Here, the recording unit 65a corresponds to one of a plurality of voice processing units in the present disclosure that receive and process voices.
The image recording unit 53 acquires an image of the surrounding environment of the host vehicle acquired by the camera 52 as a moving image. The recording unit 53 associates the acquired moving image data with the voice data acquired by the recording unit 65a and stores the same in the 1 st memory 51. Thereby, the image recording unit 53 records the image of the surrounding environment.
In the present embodiment, the IVI6 functions as an information processing device that controls the distribution of the voice acquired from the microphone 9, in addition to providing information and entertainment to the occupant of the vehicle.
IVI6 has a 2 nd processor 60 and a 2 nd memory 61. The 2 nd memory 61 is constituted by, for example, a volatile and/or nonvolatile semiconductor memory. The 2 nd processor 60 is, for example, a computer having a CPU. The 2 nd processor 60 includes an information providing section 62, a voice acquiring section 63, and a voice allocating section 64 as functional elements or functional units. The 2 nd processor 60 includes the 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, the 3 rd proxy function unit 65b3, and the call processing unit 65c as functional elements or functional units. The 2 nd processor 60 further includes a detection unit 66 and a control unit 67 as functional elements or functional units.
These functional elements can be realized by the processor 2 60 as a computer executing a program stored in the memory 2 61, for example. The computer program may be stored in advance in any storage medium readable by a computer. Alternatively, all or part of the above-described functional elements included in the 2 nd processor 60 may be configured by hardware including one or more electronic circuit components.
Here, the 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, the 3 rd proxy function unit 65b3, and the call processing unit 65c correspond to a plurality of voice processing units for receiving and processing voices in the present disclosure together with the recording unit 65a described above. Hereinafter, the 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, and the 3 rd proxy function unit 65b3 are also collectively referred to as a proxy function unit 65b. The recording unit 65a, the proxy function unit 65b, and the call processing unit 65c are collectively referred to as a speech processing unit 65.
The information providing unit 62 included in the 2 nd processor 60 communicates with various web servers (not shown) via a communication network 70 such as the internet through the TCU12 according to the related art, and provides various information and entertainment to the occupant of the vehicle via the speaker 8, the touch panel 15, and the like. The information providing unit 62 communicates with, for example, a GNSS sensor, not shown, to acquire position information of the vehicle, and performs route guidance via the touch panel 15 or the like.
The voice acquisition unit 63 acquires the sound in the vehicle interior including the voice of the vehicle user from the microphone 9.
The voice distribution unit 64 distributes and inputs the voice acquired by the voice acquisition unit 63 to the plurality of voice processing units 65. In the present embodiment, in particular, the voice distribution unit 64 switches on/off of the input of the voice to each of the voice processing units 65 under the control of the control unit 67 described later. As described above, in the present embodiment, the plurality of speech processing units 65 are the recording unit 65a, the 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, the 3 rd proxy function unit 65b3, and the call processing unit 65c of the automobile data recorder 38.
The 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, and the 3 rd proxy function unit 65b3 cooperate with proxy servers 71a, 71b, and 71c communicably connected via the TCU12 and the communication network 70 such as the internet, respectively, to provide voice proxy services to vehicle users. Hereinafter, the proxy servers 71a, 71b, and 71c are also collectively referred to as proxy servers 71. Here, the proxy servers 71a, 71b, and 71c correspond to external servers in the present disclosure.
The voice proxy service is also called a voice assistant service, and refers to a function or service that combines processing such as voice recognition processing and natural language processing, and appropriately answers a query or a request based on a speaking language from a user to execute a requested action. The proxy function unit 65b functions as a user interface for a voice proxy service, for example. In each proxy server 71, processing such as speech recognition, article understanding, response selection, and/or instruction execution is performed on the speech input from the corresponding proxy function unit 65b, and the result of the processing is returned to the proxy function unit 65b.
The 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, and the 3 rd proxy function unit 65b3 perform mutually different voice proxy services in cooperation with the proxy servers 71a, 71b, and 71c, respectively, according to the related art. For example, the 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, and the 3 rd proxy function unit 65b3 provide services of Google assistant (registered trademark), alexa (registered trademark), and CarPlay (registered trademark), respectively, as voice proxy services.
The 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, and the 3 rd proxy function unit 65b3 provide voice proxy services in which different wake-up words are set. The proxy function unit 65b corresponding to the voice proxy service starts processing of the voice proxy function by the vehicle user issuing a wake-up word of the voice proxy service to be used.
The call processing section 65c provides the telephone function based on the handsfree call to the vehicle user in cooperation with the speaker 8, the microphone 9, and the TCU12 according to the related art. In the present embodiment, in particular, the call processing unit 65c performs the handsfree call processing by acquiring the call voice of the vehicle user acquired by the microphone 9 via the voice acquisition unit 63 and the voice distribution unit 64.
The detection unit 66 detects the operation state of at least one speech processing unit 65 among the recording unit 65a, the 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, the 3 rd proxy function unit 65b3, and the call processing unit 65c of the automobile data recorder 38. Here, the operation state may include each state of recording execution and recording stop for the recording portion 65a of the automobile data recorder 38. The operation states of the proxy function unit 65b may include a standby state in which a wake-up word is received and a service execution state of a voice proxy service after the wake-up word is received. The operation states of the call processing unit 65c may include an in-call state and a call standby state.
The control unit 67 controls the operation of the voice distribution unit 64 based on the operation state of the voice processing unit 65 detected by the detection unit 66. In the present embodiment, in particular, when the detection unit 66 detects a predetermined operation state of one of the speech processing units 65 set in advance, the control unit 67 stops the input of speech to at least a part of the other speech processing units 65. Here, at least a part of the other voice processing sections 65 may include at least a part of the proxy function section 65b that provides voice proxy services.
Specifically, when the detection unit 66 detects the start of a call in the call processing unit 65c, that is, the start of a call in-progress state, the control unit 67 instructs the voice distribution unit 64 to stop inputting voice to the 1 st proxy function unit 65b1, the 2 nd proxy function unit 65b2, and the 3 rd proxy function unit 65b 3. Therefore, in the information processing system 40, even when the user's speech in the handsfree call provided by the call processing unit 65c includes any wake-up word as described above, the corresponding proxy function unit 65b can be prevented from starting the process and transmitting the user's speech to the outside of the vehicle. Thus, in the information processing system 40, the privacy protection performance can be improved.
In the present embodiment, even when the detecting unit 66 detects the start and continuation of the in-call state in the call processing unit 65c, the control unit 67 instructs the voice distributing unit 64 to continue inputting voice to the recording unit 65a of the automobile data recorder 38. Thus, in the information processing system 40, the event data recorder 38 that needs to record voice at all times can always record voice even in hands-free calling.
For example, the control unit 67 can determine another speech processing unit 65 to stop the speech input at the start of the operation of any speech processing unit 65 based on the priority table 68 stored in the 2 nd memory 61 in advance. Fig. 3 is a diagram showing an example of the priority table 68. In fig. 3, the 1 st line excluding the top header line indicates the priority of the recording unit 65a of the drive recorder 38, and the 2 nd line indicates the priority of the call processing unit 65c. The 3 rd to 5 th lines indicate priorities of the 3 1 st proxy function units 65b1, the 2 nd proxy function units 65b2, and the 3 rd proxy function units 65b3, respectively.
In the example shown in fig. 3, the recording unit 65a of the drive recorder 38 is given the highest priority "1", and the call processing unit 65c is given the next highest priority "2". The 3 proxy function units 65b are assigned the same priority "3".
When the detection unit 66 detects the start of an operation in any of the speech processing units 65, the control unit 67 refers to the priority table 68 to determine the priority given to the speech processing unit 65 that has started the operation, and instructs the speech assigning unit 64 to stop inputting speech to the speech processing unit 65 to which the same or lower priority than the priority is given. Thus, in addition to the above-described operation, for example, when the detection unit 66 detects the start of the operation of the 1 st proxy function unit 65b1, the control unit 67 instructs the voice distribution unit 64 to stop inputting voice to the other 2 nd proxy function units 65b2 and 3 rd proxy function units 65b 3.
When the call processing unit 65c performs call processing, the control unit 67 displays information of the voice processing unit 65 to which the voice is input from the voice distribution unit on the touch panel 15 as a display device. Fig. 4 is a diagram showing an example of a voice input information screen displayed on the display 16 of the touch panel 15 by the control unit 67.
In the voice input information screen 72 shown in fig. 4, labels 73a, 73b, 73c, 73d, and 73e written with "car recorder", "handsfree call", "1 st agent", "2 nd agent", and "3 rd agent" are displayed in correspondence with the recording unit 65a, call processing unit 65c, 1 st agent function unit 65b1, 2 nd agent function unit 65b2, and 3 rd agent function unit 65b3 of the car recorder 38. Labels 73c, 73d, and 73e corresponding to the 1 st agent function unit 65b1, the 2 nd agent function unit 65b2, and the 3 rd agent function unit 65b3, which are not currently inputted with speech from the speech assigning unit 64, are displayed in gray (shown in a ruled line in the drawing), for example.
Thus, the vehicle user can confirm the input state of the voice to each voice processing unit 65, and thus can perform a call without worrying about leakage of the call to the outside of the vehicle.
Further, on the voice input information screen 72 shown in fig. 4, buttons 74a, 74b, 74c, 74d, 74e for switching the state of voice input from the voice distribution unit 64 to the corresponding voice processing unit 65 are displayed on the right side of the drawing of the labels 73a, 73b, 73c, 73d, and 73e, respectively. By operating these buttons, the vehicle user can input a switch instruction to turn on/off the voice input to the corresponding voice processing unit 65.
Thus, when the call processing unit 65c performs call processing, the control unit 67 can switch on/off of the voice input from the voice distribution unit 64 to each of the voice processing units 65 in accordance with the above-described switch instruction input by the vehicle user. For example, when the vehicle user wants to use an arbitrary voice proxy service during the execution of the handsfree call, the handsfree call can be temporarily set to a mute state and the voice input to the desired proxy function section 65b can be turned on by performing a switch instruction using the above-described button.
Next, the sequence of the operations of the voice distribution from the voice acquisition unit 63 to the voice processing unit 65 in the information processing system 40 will be described. Fig. 5 is a flowchart showing the sequence of the voice allocation process in the information processing system 40. The process of fig. 5 is repeatedly performed.
When the processing is started, first, the voice distribution section 64 starts inputting the voice acquired from the microphone 9 by the voice acquisition section 63 to the voice processing section 65 (S100). Next, the detection unit 66 determines whether or not the start of the handsfree call in the call processing unit 65c is detected (S102), and when the start of the call is detected (S102, yes), the control unit 67 refers to the priority table 68 to stop the input of the voice to the proxy function unit 65b (S104), the proxy function unit 65b having a priority equal to or lower than the priority given to the call processing unit 65c. The control section 67 instructs the voice distribution section 64 to stop the voice input.
Next, the control unit 67 displays voice input information, which is information of the voice processing unit 65 to which the voice is input from the voice distribution unit, on the touch panel 15 (S106). This display is performed by, for example, the control unit 67 displaying a voice input information screen 72 as shown in fig. 4 on the touch panel 15.
Next, the control unit 67 determines whether or not the vehicle user has input a switching instruction for voice input (S108). The switching instruction can be input by, for example, the operation of the buttons 74a, 74b, 74c, 74d, and 74e on the voice input information screen 72 shown in fig. 4. When a switching instruction is input in step S108 (yes in S108), the control unit 67 switches on/off of the voice input of the corresponding voice processing unit 65 according to the input switching instruction (S110).
Next, the detection unit 66 determines whether or not the call is ended (S112). Then, when the call ends (yes at S112), the control unit 67 starts the voice input to all the voice processing units 65 (S114), and ends the processing.
On the other hand, when the switching instruction is not input in step S108 (no in step S108), the process proceeds to step S112. On the other hand, when the call is not ended in step S112 (no in S112), the detection unit 66 returns the process to step S108.
On the other hand, when the start of the handsfree call is not detected in step S102 (no in S102), the detection unit 66 determines whether or not the start of the operation of any of the proxy function units 65b is detected (S116). When the operation of the proxy function unit 65b is not started (no in S116), the detection unit 66 returns to step 102 and repeats the processing.
On the other hand, when the operation of any one of the proxy function units 65b is started (yes in S116), the control unit 67 refers to the priority table 68 and stops the input of speech to the other proxy function unit 65b (S118).
Next, the control unit 67 displays voice input information, which is information of the voice processing unit 65 to which the voice is input from the voice distribution unit 64, on the touch panel 15 (S120). Next, the control unit 67 determines whether or not the vehicle user has input a switching instruction for voice input (S122). When a switching instruction is input (yes in S122), the control unit 67 switches on/off of the voice input of the corresponding voice processing unit 65 according to the input switching instruction (S124).
Next, the detection unit 66 determines whether or not the operation in the proxy function unit 65b started in step S116 has ended (S126). Then, when the above-described operation has ended (yes in S126), the control unit 67 shifts the process to step S114.
On the other hand, when the switching instruction is not input in step S122 (no in step S122), the process proceeds to step S126. On the other hand, in step S126, when the operation in the proxy function unit 65b started in step S116 is not completed (S126, no), the detection unit 66 returns the process to step S122.
The present invention is not limited to the configuration of the above-described embodiment, and may be implemented in various modes within a range not departing from the gist thereof.
