The invention will be further explained by the description of the embodiments with reference to the drawings.
The embodiment provides a voice assistant control method, which is applied to a smart television comprising a bottom resident service and an upper service distribution module, and as shown in fig. 1 and fig. 2, the method includes:
s100, when the intelligent television receives a voice instruction of the voice assistant, the target characteristic value corresponding to the voice assistant is obtained through the bottom resident service.
In this embodiment, the voice assistant refers to amazon voice, google family and other voice assistants, and at present, a plurality of voice assistants are generally integrated with an intelligent television in the market, and different voice assistants process respective logics respectively without mutual influence. However, for different voice assistant products, different logics such as voice recognition, semantic analysis, cloud interaction, intention encapsulation and the like are basically concentrated; after these links are completed, the intelligent device is finally needed to process specific behaviors, and the part of logic is consistent for different voice assistants. Therefore, in the embodiment of the invention, through a set of unified voice interface layer, all voice assistants automatically recognize according to the keywords, and separately send actual intentions (namely actual operation instructions such as channel switching, information source switching, video playing and the like) to the voice unified interface layer, and the voice unified interface layer processes subsequent behaviors so as to achieve the purposes of saving resources and being easy to expand.
In this embodiment, after the smart television is turned on, the bottom resident service is automatically started, so that the following steps are further included before the voice instruction of the voice assistant is received:
when receiving the starting broadcast, automatically starting the bottom layer resident service; or
And registering the bottom layer resident service as a system core service.
Specifically, a mode that the voice assistant application starts the service after receiving the startup broadcast can be adopted, when the television is started, the voice application receives the startup broadcast, and the bottom-layer service can be started after the startup broadcast is received; or, a mode of registering the service as the system core service is adopted, so that after the service is registered as the system core service, the ServiceManager module automatically starts the bottom layer resident service as the necessary service of the system in the starting process of the system.
Further, in this embodiment, before receiving the voice instruction of the voice assistant, the method further includes:
s10, setting corresponding characteristic values for different voice assistants in advance;
and S20, establishing a mapping relation between the voice assistant and the characteristic value according to the characteristic values corresponding to different voice assistants.
Specifically, in the embodiment of the present invention, different feature values of the voice assistant are defined, for example, amazon is 1, Google is 2, in practical applications, a feature value of a voice assistant may be a string of encrypted long character strings, when a server of amazon receives a voice instruction, the voice instruction carries a feature value corresponding to amazon, and it can be understood that when servers of other software assistants such as Google receive a voice instruction, the voice instruction also carries a feature value corresponding to Google. It should be noted that the predefined feature values of different voice assistants are defined in the underlying service in a certain interval, because the same voice assistant may correspond to multiple feature values, so that when the feature values of the voice assistants are in the interval, it is stated that the voice assistants belong to the same type.
Therefore, when receiving a voice instruction of the voice assistant, acquiring the target feature value corresponding to the voice assistant through the bottom resident service specifically includes: and when a voice instruction of the voice assistant is received, acquiring a target characteristic value corresponding to the voice assistant through the bottom resident service according to the mapping relation. That is, whether the voice assistant is a corresponding voice assistant type can be identified according to whether the feature value of the voice assistant is in a predefined interval, that is, it can be distinguished which voice assistant, such as a voice instruction from amazon, needs to be identified as amazon assistant and cannot be identified as google assistant. Since the subsequent processing flows of different voice assistants may be different, in order to avoid instruction processing errors, the corresponding feature values need to be accurately identified.
S200, the intelligent television sends the voice instruction to the corresponding voice server according to the target characteristic value, so that the voice server analyzes the operation instruction corresponding to the voice instruction.
In the embodiment, different sub threads are respectively started to connect with respective voice servers according to the working modes of different voice assistants, wherein the voice servers are cloud servers and are used for semantic recognition, namely, words spoken by a user are analyzed into actual instructions and long connection is kept; the reason that long connection needs to be kept is that a user may have a voice demand at any time, and when the user speaks, the server is needed to analyze the spoken words of the user into instructions and feed the instructions back to the smart television; in the case of a short connection, it may happen that there is no way to instantly parse the user's language while the user is speaking. It should be noted that, in the embodiment of the present invention, for a voice assistant that needs to be found by a device in a local area network, a sub-thread needs to be started again to continuously detect and find the device in the local area network and perform connection, for example, for HomeKit (which is an intelligent home platform released in apple 2014), an intelligent television needs to be connected with a mobile phone, a user speaks towards the mobile phone, and a final instruction is sent to a television terminal for processing.
S300, the intelligent television receives the operation instruction, and the operation instruction is sent to the shared response module through the upper-layer service distribution module.
In this embodiment, receiving the operation instruction, and sending the operation instruction to the shared response module through the upper service distribution module includes:
s301, receiving an operation instruction, calling a message forwarding interface, and forwarding the operation instruction to an upper-layer service distribution module;
and S302, sending the operation instruction and the target characteristic value to a shared response module through an upper-layer service distribution module.
Specifically, when the underlying resident service receives the message from each voice server, the underlying resident service calls an amazon operation instruction parsing method according to which voice assistant the instruction comes from according to the feature value, and parses a keyword of the operation instruction, if the keyword is a channel switching action and the channel name is CCTV 1; if the resolution fails, the user is prompted for not resetting (no reaction). And finally, calling a message forwarding interface of the bottom layer resident service, forwarding the message to the upper layer service distribution module, and then carrying out actual forwarding or processing on an operation instruction from the bottom layer resident service when the upper layer service distribution module receives the operation instruction, wherein real channel switching can be processed if the channel switching is carried out.
Correspondingly, the sending of the operation instruction and the target characteristic value to the shared response module by the upper-layer service distribution module includes:
determining corresponding sub-modules in the operation instruction and the response module;
and forwarding the operation instruction and the target characteristic value to the sub-module through the upper-layer service distribution module so that the sub-module responds to the operation instruction according to the target characteristic value.
Specifically, as shown in fig. 2, the sub-modules include one of a live application, a source application, a setup application, a media application, and a search application, wherein the definition of each sub-module is as follows:
LiveTV (live broadcast application) refers to specific programs watched on a television, such as CCTV1, Shenzhen satellite television and the like, and is played by the application;
input (source application), sources on television, such as HDMI1, HDMI2, TV, etc., are all provided by the application;
settings, set menus on the tv, such as adjusting the backlight, adjusting the brightness, etc., are provided by the application;
media (Media application), local Media playback on television, such as playing MP4 files on a U-disc, provided by the application;
search (Search application), Search on television, such as searching for a video name, is provided and exposed by the application.
Therefore, for different voice assistant products, the response modules configured by the smart television are consistent, that is, the logic in the response modules is consistent for different voice assistants, so that different voice assistants can share the response modules, and when the response modules process control instructions of different voice assistants, the purpose of saving system resources is achieved, and meanwhile, the further expansion of the television function is facilitated, and the labor cost is reduced. For example, taking an operation instruction as an example of channel switching, when receiving a channel switching instruction, the upper layer service distribution module sends the channel switching instruction to the live broadcast application sub-module, and then the live broadcast application sub-module switches channels. However, since the specific processing flows of different voice assistants may be different, when the sub-module receives a specific operation instruction, it needs to determine a target feature value, that is, it needs to know the specific voice assistant, so that the sub-module can execute the control instruction more accurately.
