Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
At present, vehicle-mounted terminals are mostly installed in vehicles, voice control applications can be installed in the vehicle-mounted terminals, and the voice control applications can collect voices spoken by users to generate corresponding control instructions so as to control components in the vehicles to execute corresponding operations. Therefore, the hands of the user can be released in the driving process of the vehicle, and the driving safety of the vehicle is further ensured. There may also be other applications or devices that need to collect speech, usually while the user is driving the vehicle; if the mobile phone can be connected with the vehicle-mounted terminal through the Bluetooth, when a user answers a call, the mobile phone collects voice through the vehicle-mounted terminal so as to carry out a call. At this time, the voice control application needs to be prohibited from collecting voice, and the voice control application is enabled to resume voice collection when the phone is hung up. At present, a vehicle-mounted terminal determines whether a mobile phone hangs up or not by acquiring Bluetooth state information of the mobile phone, and then enables a voice control application to recover voice acquisition when the mobile phone hangs up. However, for a mobile phone installed with a specific operating system, when a user clicks a hang-up button on the mobile phone to hang up the phone, the bluetooth state information of the mobile phone is not changed, and the bluetooth state information still indicates that the mobile phone is in a call state; therefore, the vehicle-mounted terminal cannot determine that the mobile phone is hung up according to the Bluetooth state information, and the voice control application cannot recover voice collection. If the user issues the control instruction for the components in the vehicle through voice at this time, the voice control application cannot control the components in the vehicle according to the instruction, so the effect of the voice control application on controlling the components in the vehicle is poor.
The following embodiments of the application provide a voice collection method, which can accurately determine that a mobile phone does not need to perform voice collection, so that the voice collection of a voice control application is recovered, and the control effect of the voice control application on components in a vehicle is ensured.
The embodiment of the application provides a vehicle-mounted terminal, wherein a system program (such as an android operating system) and an application program (hereinafter referred to as an application) can be installed in the vehicle-mounted terminal.

Those skilled in the art will appreciate that the configuration shown in FIG. 2 is not intended to be limiting of the in-vehicle terminal 10, and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components may be employed.
Fig. 2 is a flowchart of a speech acquisition method according to an embodiment of the present application. The method may be used for the in-vehicle terminal 10 in fig. 1, and as shown in fig. 2, the method may include:
It should be noted that, when the vehicle-mounted terminal is in communication connection with the target terminal and the target terminal is in the voice acquisition state, the corresponding application in the vehicle-mounted terminal may be in the running state. Illustratively, the target terminal is connected with the vehicle-mounted terminal through bluetooth, the target terminal collects voice through the vehicle-mounted terminal to carry out conversation, and a bluetooth telephone application of the vehicle-mounted terminal can be in a running state. Furthermore, the in-vehicle terminal may determine that at least one application running therein includes the bluetooth phone application, and the bluetooth phone application has a voice capture function. When the target terminal hangs up the phone, the target is switched on and off to exit the call state, so that the Bluetooth phone application of the vehicle-mounted terminal can stop running, and at least one application detected by the vehicle-mounted terminal can not comprise the Bluetooth phone application. At this time, if there is no other running application with the voice acquisition function in the vehicle-mounted terminal, the vehicle-mounted terminal may run the voice control application to control the component in the vehicle in which the vehicle-mounted terminal is located. Optionally, in this embodiment of the present application, the target terminal acquires the voice through the vehicle-mounted terminal, and may refer to that the target terminal acquires the voice through a microphone in the vehicle-mounted terminal.
It should be noted that, in the embodiment of the present application, when the target terminal performs a call, the vehicle-mounted terminal runs the bluetooth phone application, and then the target terminal collects voice through the vehicle-mounted terminal as an example; optionally, when the target terminal performs other work, the voice may be collected by the vehicle-mounted terminal by running a corresponding application in the vehicle-mounted terminal. If the target terminal is recording, the vehicle-mounted terminal can run the Bluetooth recording application, and then the target terminal collects voice through the vehicle-mounted terminal.
To sum up, in the voice collecting method provided in the embodiment of the present application, the vehicle-mounted terminal may directly determine whether each application in the at least one running application has the voice collecting function, and then run the voice control application when it is determined that the at least one application does not have the voice collecting function. According to the embodiment of the application, the target terminal is not determined to be not in the voice acquisition state through the Bluetooth state information of the target terminal, so that the situation that the voice control application cannot run and the vehicle-mounted terminal cannot realize voice control because the Bluetooth state information is not changed when the target terminal exits the voice acquisition state is avoided, and the voice control effect of the vehicle-mounted terminal is ensured.
Fig. 3 is a flowchart of another speech acquisition method according to an embodiment of the present application. The method may be used for the in-vehicle terminal 10 in fig. 1, and as shown in fig. 3, the method may include:
Alternatively, the in-vehicle terminal may determine the application running therein (i.e., the application in the running state) in real time. It should be noted that the application herein may refer to a complete application installed in the vehicle-mounted terminal, or may be a functional module used for implementing a certain function in an application, and the functional module may include a part of codes in the application. For example, at least one application running in the in-vehicle terminal may include a camera application, at which time a camera of the in-vehicle terminal may capture an image, and a display screen of the in-vehicle terminal may display the captured image. For another example, at least one application running in the vehicle-mounted terminal may include a functional module corresponding to an image capturing function of the camera application, and at this time, the camera of the vehicle-mounted terminal may capture an image, but the display screen of the vehicle-mounted terminal may not display the captured image.
It should be noted that, the determining, by the vehicle-mounted terminal, the running application in real time in the embodiment of the present application may refer to determining, by the vehicle-mounted terminal, the running application every target time length, where the target time length is shorter. For example, the target duration is less than the duration threshold, e.g., the duration threshold may be 1 second, 0.5 second, or even less.
The vehicle-mounted terminal can determine whether each application in the at least one application has a voice acquisition function, and further determine whether a target application with the voice acquisition function exists in the at least one application.
Optionally, a section of monitoring code may be stored in the vehicle-mounted terminal, and for example, the section of monitoring code may be called a listener (english: listener). The vehicle-mounted terminal can continuously run the section of monitoring code to monitor the use condition of each application in the vehicle-mounted terminal on the microphone, and further determine a target application with a voice acquisition function in at least one running application, namely the target application using the voice acquisition function.
It should be noted that, in the embodiment of the present application, for example, the vehicle-mounted terminal determines at least one running application first, and then determines whether the at least one application has the voice collecting function, so as to determine whether a target application currently using the voice collecting function exists, that is, whether a target application currently performing voice collecting exists. Optionally, the in-vehicle terminal may also directly traverse all the applications installed therein (for example, the number of the applications is at least one), and then determine whether the target application having the voice acquisition function and having the voice acquisition function in an on state is included in all the applications, so as to determine whether the target application currently using the voice acquisition function exists. It should be noted that, in the embodiment of the present application, at least one running application is directly determined, and then it is determined whether a target application exists in the at least one running application, so that the range of performing the search is small, and the search speed is high.
After the vehicle-mounted terminal determines that the target application exists, the vehicle-mounted terminal can further judge the target application to determine the relation between the target application and the voice control application, and further determine whether to run the voice control application.
For example, the in-vehicle terminal may determine a User Identifier (UID) of the target application. It should be noted that the UID of an application may be used to identify the application, the terminal may assign a different UID to each application to distinguish the applications, and the corresponding UIDs of the same application installed on different terminals may be different.
It should be noted that, in step 302, the in-vehicle terminal may determine a plurality of target applications, and in this case, in step 303, the in-vehicle terminal needs to determine the user identifier of each target application.
It should be noted that the package name of an application is used to uniquely identify an application, and the package name of the same application does not change regardless of which terminal the same application is installed on. When the in-vehicle terminal determines the user identifiers of the plurality of target applications in step 303, the in-vehicle terminal may determine the package name of each target application according to the user identifier of each target application in step 304.
For example, the in-vehicle terminal may determine the packet name of the voice control application in advance, and may directly compare the packet name of the target application with the packet name of the voice control application after determining the packet name of the target application.
It should be noted that, when the in-vehicle terminal determines the package names of the multiple target applications in step 304, the in-vehicle terminal needs to determine whether the package names of each of the multiple target applications applied to the voice control application are the same in step 305.
When the packet name of the target application is the same as that of the voice control application, the vehicle-mounted terminal can determine that the target application is the voice control application, and further can determine that the voice control application is running currently and the voice acquisition function of the voice control application is in an open state.
It should be noted that, because the package name of each application can uniquely identify the application, in the embodiment of the present application, the package name of the target application is determined by the UID of the target application, and then it is determined whether the package name is the same as the package name of the voice control application, so as to determine whether the target application is the target application of the voice control application. Therefore, the accuracy of judging the target application can be ensured, and the situation that judgment is wrong due to the fact that other information of the application is adopted for judging is avoided.
When the packet name of the target application is different from that of the voice control application, the vehicle-mounted terminal can determine that the target application is not the voice control application, and further can determine that the voice control application is not operated currently and the voice acquisition function of the voice control application is not in an open state.
Optionally, in the embodiment of the present application, each application in the in-vehicle terminal has a priority. It should be noted that the priority of the application described in the embodiment of the present application refers to the priority of the application for collecting voice, and may also refer to the priority of the application for using a microphone in the in-vehicle terminal.
Optionally, the in-vehicle terminal may determine whether the package name set of the application includes the package name of the target application, and further determine whether the application set includes the target application. The vehicle-mounted terminal may store a package name set of an application, and the package name set of the application may include at least one package name of the application. The at least one application may be an application in the application set, that is, the package name set of the application includes a package name of each application in the application set. The priority of the applications in the application set may be lower than that of the voice control application, that is, the application set is a set composed of at least one application with a lower priority than that of the voice control application.
When the vehicle-mounted terminal determines that the package name set comprises the package name of the target application, the vehicle-mounted terminal may determine that the application set comprises the target application, and further determine that the priority of the target application is lower than that of the voice control application. Further, the in-vehicle terminal may determine that the voice control application can perform voice collection more preferentially than the target application, and the voice control application can use the microphone of the in-vehicle terminal more preferentially.
When the vehicle-mounted terminal determines that the packet name set does not include the packet name of the target application, the vehicle-mounted terminal may determine that the application set includes the non-target application, and further determine that the priority of the target application is higher than or equal to the priority of the voice control application. Further, the in-vehicle terminal may determine that the target application can perform voice collection more preferentially than the target application, or that the target application and the voice control application perform voice collection with a comparable degree of priority.
It should be noted that, in the embodiment of the present application, the vehicle-mounted terminal determines whether the priority of the target application is lower than the priority of the voice control application by determining whether the packet name set of the application includes the packet name of the target application. Alternatively, the in-vehicle terminal may determine whether the priority of the target application is lower than that of the voice control application in other manners. For example, the in-vehicle terminal may set a corresponding numerical value for the priority of each application, and for example, a larger numerical value may be used to indicate a larger priority. And further directly determining whether the numerical value corresponding to the priority of the target application is smaller than the numerical value corresponding to the priority of the voice control application so as to determine whether the priority of the target application is lower than the priority of the voice control application.
On one hand, when it is determined in step 302 that the at least one running application does not have the voice acquisition function, that is, it is determined that there is no target application using the voice acquisition function currently, the vehicle-mounted terminal may run the voice control application to control a component in the vehicle where the target vehicle-mounted terminal is located.
On the other hand, when it is determined in step 308 that the priority of the target application is lower than that of the voice control application, the in-vehicle terminal may also run the voice control application to control the components in the vehicle in which the target in-vehicle terminal is located. Optionally, at this time, the vehicle-mounted terminal may stop running the target application, or may continue running the target application, that is, running the target application and the voice control application at the same time, which is not limited in this embodiment of the present application.
And step 310, continuing to run the target application.
On one hand, when the vehicle-mounted terminal determines that the target application is the voice control application in step 306, the vehicle-mounted terminal does not need to change the running state of the current application, and can continue to run the target application, that is, continue to run the voice control application.
On the other hand, after step 308, when the vehicle-mounted terminal determines that the target application is not the voice control application and the priority of the target application is higher than or equal to the priority of the voice control application, the vehicle-mounted terminal may not need to change the running state of the current application, and may continue to run the target application.
In the embodiment of the present application, when it is determined in step 307 that the target application is not the voice control application, the in-vehicle terminal executes step 308 to determine the priority level of the target application and the voice control application as an example. Optionally, when the target application is not the voice control application, the vehicle-mounted terminal may also directly continue to run the target application, and prohibit the voice control application from running. This case also corresponds to the priority of the speech control application being the lowest priority of all applications.
It should be noted that, in the embodiment of the present application, the vehicle-mounted terminal may directly determine a target application in which voice collection is being performed (that is, a microphone is used), and when the target application does not exist, run the voice control application to control a component in a vehicle in which the vehicle-mounted terminal is located. The vehicle-mounted terminal can also determine whether to run the voice control application according to the priority of each application, so that the flexibility of running the voice control application is ensured, and the flexibility of controlling components in the vehicle is further ensured. In addition, even if the vehicle-mounted terminal is in communication connection with the target terminal, whether the microphone is used by the application can be accurately determined directly through detection of the application in the vehicle-mounted terminal, and whether the voice control application is operated can be further determined, and whether the voice control application is operated does not need to be determined based on information of the target terminal. Therefore, the accuracy of the time for operating the voice control application is ensured, and the control effect of the voice control application on the components in the vehicle is ensured.
To sum up, in the voice collecting method provided in the embodiment of the present application, the vehicle-mounted terminal may directly determine whether each application in the at least one running application has the voice collecting function, and then run the voice control application when it is determined that the at least one application does not have the voice collecting function.
