Based on the hardware structure, the embodiment of the voice triggering method is provided.
The invention provides a voice triggering method, in an embodiment of the voice triggering method, referring to fig. 2, the voice triggering method includes:
step S10, if a voice trigger event is detected, acquiring the input method state of a preset voice input method;
step S20, if the input method state is a pop-up state, starting a first recording function of the voice input method;
step S30, if the input method state is a non-pop-up state, generating a voice static broadcast according to the voice trigger event, and triggering a preset voice assistant based on the voice static broadcast to start a second recording function of the voice assistant.
The voice triggering method is mainly applied to the smart television and comprises the following specific contents:
step S10, if a voice trigger event is detected, acquiring the input method state of a preset voice input method;
the voice trigger event refers to an Android standard voice key event triggered by a user on a remote controller, for example, when the user presses a voice key on the remote controller, the voice trigger event is triggered. In order to call the voice interaction function, the smart television needs to start a recording function. Generally, a voice assistant and a voice input method in the smart television have a recording function. It will be appreciated that in a practical application scenario, the phonetic input method will have priority over the voice assistant, and thus normally it is a voice-triggered event that triggers the phonetic input method preferentially. In the embodiment, the voice input method is executed on the Android system bottom layer of the smart television and can receive all key events in the system, so that the voice input method can achieve global voice triggering in the system. I.e. once a voice trigger event is detected, the voice input method can be triggered. In this embodiment, the input method status is used as a criterion for determining whether the voice input method is triggered.
Step S20, if the input method state is a pop-up state, starting a first recording function of the voice input method;
supposing that the input method state of the voice input method in the intelligent television is a popup state, the current voice input method calls an input method interface, a voice trigger event triggers the voice input method, and the voice interaction process is realized through the functions of the voice input method. The called input method interface can be displayed on a display screen of the smart television, such as a voiceprint interface, and when the input method state is a popup state, the displayed input method interface can be intuitively perceived by a user. The voice input method is directly called, and the control is not performed through the traditional controller scheme, so that the trigger response speed of the voice interaction method is higher, after the voice interaction process is determined to be processed by the voice input method, the first recording function of the voice input method can be started, and the voice interaction instruction of the user is analyzed and processed through the first recording function. The process does not need a controller for control analysis any more, reduces the interference processing of the controller, and effectively determines the attribution control right of the voice interaction function according to the input method state of the voice input method.
Step S30, if the input method state is a non-pop-up state, generating a voice static broadcast according to the voice trigger event, and triggering a preset voice assistant based on the voice static broadcast to start a second recording function of the voice assistant.
If the input method state is a non-popup state, the fact that the current voice input method does not call an input method interface is proved, the voice input method does not process a voice trigger event, the current voice trigger event is not occupied and consumed, and at the moment, the event returns to a frame layer in the smart television system. After receiving the returned voice trigger event, the frame layer generates a broadcast event representing the voice trigger according to the voice trigger event, wherein the broadcast event is a voice static broadcast and is used for triggering a voice assistant in the frame layer. It is understood that the voice assistant is a preset voice service process in the smart television, the process is in a closed state, and the voice static broadcast as a trigger factor can directly trigger the voice assistant to start the voice assistant to activate the second recording function of the voice assistant.
The embodiment is not controlled by a traditional controller scheme any more, so that the trigger response speed of the method is higher, after the voice interaction process is determined to be processed by the voice input method, the first recording function of the voice input method can be started, and the voice interaction instruction of the user is analyzed and processed by the first recording function. The process does not need a controller for control analysis any more, reduces the interference processing of the controller, and effectively determines the attribution control right of the voice interaction function according to the input method state of the voice input method.
Further, if the input method state is a non-pop-up state, the step of generating a voice static broadcast according to the voice trigger event includes:
step A1, if the input method state is a non-pop-up state, generating a voice assistant specific character based on the voice trigger event, and generating a voice static broadcast according to the voice assistant specific character and the voice trigger event.
In this embodiment, there may be other special processes in the frame layer, where the special processes may be malicious monitoring processes or unknown processes with priorities greater than that of the voice assistant, and these special processes may intercept and intercept the voice trigger event, so that the smart television cannot be normally applied to the voice trigger event, and the voice interaction function fails. In order to ensure that the voice trigger event can normally trigger the voice assistant and is not consumed by any other process interception, the embodiment generates a voice assistant specific character based on the voice trigger event, and the voice assistant specific character marks a trigger object and a consumption object of the voice trigger event, that is, the trigger object and the consumption object specifying the voice trigger event are only the voice assistant and cannot be consumed by other object interception. Therefore, the present embodiment generates the voice assistant specific character based on the voice trigger event, and generates the voice static broadcast according to the voice assistant specific character and the voice trigger event. Through the exclusive character of the voice assistant, the voice trigger event is determined to be only consumed by the voice assistant, so that the scheme integrity of the embodiment of the invention is ensured.
Further, if the input method state is a non-pop-up state, the step of generating a voice static broadcast according to the voice trigger event includes:
step A2, if the input method state is a non-popup state, popup state anomaly detection is carried out on the voice input method, and a detection result is obtained;
specifically, in order to avoid the abnormal phenomenon that the voice assistant is finally triggered by errors due to the fact that the voice input method does not pop up the input method interface normally, a detection mechanism is added in the process of determining that the input method state is the non-pop-up state so as to detect whether the voice input method is in the pop-up state abnormal state or not. The pop-up state abnormity detection is carried out on the voice input method, and a detection result is obtained.
Step A3, if the detection result is that the pop-up state is abnormal, outputting abnormal early warning information;
and step A4, if the detection result is that the pop-up state is normal, generating a voice static broadcast according to the voice trigger event.
If the detection result is that the pop-up state is abnormal, the fact that abnormal operation possibly exists in the process of calling the interface by the input method of the current voice input method is proved. For example, the voice input method actually detects a voice trigger event, but due to calling out in time or calling parameters being wrong, the input method interface pop-up process is abnormal, at this time, in order to ensure normal operation of the embodiment of the present invention, the smart television outputs abnormal early warning information, so as to provide the user to perform abnormal elimination processing on the voice input method, such as shutdown and restart, data initialization, and other operations.
If the detection result is that the pop-up state is normal, it is proved that the current voice trigger event does not trigger the voice input method, and at the moment, the smart television generates voice static broadcast according to the voice trigger event.
The embodiment provides a pop-up state anomaly detection mechanism, effectively avoids the phenomenon that the error change of the object is triggered due to the pop-up anomaly of the input method interface, and improves the fault-tolerant mechanism of the smart television.
Further, if the input method state is a non-pop-up state, generating a voice static broadcast according to the voice trigger event, and triggering a preset voice assistant based on the voice static broadcast to start a second recording function of the voice assistant further includes:
step a, if the second recording function does not acquire any voice interaction event within a preset time length, releasing the memory resource occupied by the voice assistant.
Assuming that the voice-triggering event of the present invention triggers the voice assistant, the recording will be performed by the second recording function of the voice assistant. In reality, there may be a situation where the voice trigger event is a false touch, and this phenomenon may cause the voice assistant to not receive any voice interaction instruction for a long time, i.e. not have any voice input. It can be understood that the invention uses two interactive modes of voice input method and voice assistant, and the voice input method is used as the global application of the system and usually resides in the memory. And the voice assistant is not applied globally by the system and is applied less frequently than the voice input method. Therefore, in order to avoid the influence on the operation performance of the smart television caused by the fact that the memory resource is always occupied, the preset duration is set for the second recording function. And if the second recording function does not acquire any voice interaction event within the preset time length, automatically releasing the memory resources occupied by the current voice assistant. The voice interaction event refers to a voice instruction sent by a user, and if the voice interaction event is not received within a preset time length, the fact that the current scene is not a voice interaction scene is proved, and the voice trigger event may be a false touch. At this moment, the voice assistant is closed, and the memory resource occupied by the voice assistant is released, so that the memory resource of the smart television can be prevented from being occupied by the voice assistant, the waste of terminal operation resources is avoided, the operation memory is optimized, and the operation performance of the smart television is improved.
In the invention, if a voice trigger event is detected, whether a preset voice input method calls an input method interface is judged; if yes, starting a first recording function of the voice input method; and if not, generating a voice static broadcast according to the voice trigger event, and triggering a preset voice assistant based on the voice static broadcast to start a second recording function of the voice assistant. According to the invention, by reducing the intermediate broadcasting process of the controller, the dependence of the intelligent television on the controller is reduced, the stability of the intelligent television is improved, the voice interaction process is simplified, the response speed of voice trigger is greatly improved, and meanwhile, through the awakening mechanism, the voice assistant does not need to reside in a memory, so that the memory consumption of the intelligent television is greatly reduced, the operation burden is reduced, and the operation performance of the intelligent television is improved.
Further, based on the first embodiment, a second embodiment of the voice trigger method of the present invention is provided, in which if a voice trigger event is detected, the step of acquiring an input method state of a preset voice input method includes:
step B1, if a voice trigger event is detected, judging whether a voice awakening word exists in the voice trigger event;
specifically, the voice trigger event may be a key trigger performed by a remote controller of the smart television, or a voice trigger performed by a voice receiver. Assuming that the voice is triggered, the user may wake up the corresponding trigger object by a voice wake-up word, such as "trigger voice input method" or "trigger voice assistant" by adding the voice wake-up word to the voice. Therefore, there is a need for voice wake word detection for voice triggered events.
Step B2, if yes, determining the awakening attribute of the voice awakening word;
step B3, if the voice awakening attribute is a voice input method attribute, starting a first recording function of the voice input method;
step B4, if the voice awakening attribute is a voice assistant attribute, starting a second recording function of the voice assistant;
if the voice awakening word exists, the user already determines the trigger object, and the corresponding recording function is started according to the voice awakening word. The key point is that the awakening attribute of the voice awakening word is determined, if the voice awakening attribute is the attribute of the voice input method, a first recording function corresponding to the voice input method is started, and if the voice awakening attribute is the attribute of the voice assistant, a second recording function corresponding to the voice assistant is started.
And step B5, if not, acquiring the input method state of the preset voice input method.
And if the voice awakening word does not exist, directly acquiring the input method state of the voice input method, and determining the voice trigger object according to the input method state.
Further, based on the first embodiment, a third embodiment of the voice trigger method of the present invention is provided, in which the step of acquiring the input method state of the preset voice input method includes:
step C1, acquiring the device serial number and the triggering time stamp in the voice triggering event;
step C2, if the equipment serial number is consistent with the preset serial number and the triggering timestamp is consistent with the current timestamp, determining that the voice triggering event is a legal triggering event;
and step C3, if the voice trigger event is a legal trigger event, acquiring the input method state of the preset voice input method.
The voice trigger event may be a forged illegal event, and in order to ensure data security of the smart television, in this embodiment, validity verification is performed by acquiring a device serial number and a trigger event stamp in the voice trigger event. The equipment serial number is an equipment authentication number of an equipment source of a voice trigger event, and usually a set of intelligent television systems are generated by the same manufacturer, so the equipment serial number is an important factor of legality authentication; and secondly, the triggering time stamp proves the generation time of the current voice triggering event, and the encryption algorithm is used for keeping secret, so that the interference and confusion of other malicious time stamps are avoided. Correspondingly, the smart television stores a preset serial number and a current timestamp, if the equipment serial number and the trigger timestamp are legal, the preset serial number and the preset timestamp in the smart television respectively correspond to the equipment serial number and the trigger timestamp, the verification is passed, the voice trigger event is a legal trigger event, and the smart television acquires the input method state of the preset voice input method; otherwise, the smart television cannot match the equipment serial number and the trigger timestamp, the verification fails, and the voice trigger event is an illegal trigger event and is not processed.
Further, based on the first embodiment, a fourth embodiment of the voice triggering method of the present invention is provided, in which the voice triggering method further includes:
b, uploading a voice interaction instruction obtained according to the first recording function or the second recording function to a preset cloud platform;
step c, acquiring a voice control instruction fed back by the preset cloud platform based on the voice interaction instruction, and determining a target application of the voice control instruction;
and d, sending the voice control instruction to the target application.
In this embodiment, the voice interaction instruction obtained by the voice input method or the voice assistant is uploaded to the cloud platform, and a voice control instruction of the cloud platform is obtained, where the voice control instruction corresponds to a target application to be controlled. In the conventional voice triggering scheme, a voice control instruction needs to be analyzed and filtered by a controller, and the obtained final voice instruction can be sent to a corresponding target application for processing by a target application process. However, the embodiment does not have a link of the controller, so that the voice control instruction can be directly sent to the target application, and the target application can acquire the voice control instruction more quickly, so that voice feedback and response are performed more quickly.
In addition, an embodiment of the present invention further provides a voice trigger device, where the voice trigger device includes:
the state module is used for acquiring the input method state of a preset voice input method if a voice trigger event is detected;
the pop-up module is used for starting a first recording function of the voice input method if the input method state is the pop-up state;
and the non-pop-up module is used for generating a voice static broadcast according to the voice trigger event if the input method state is a non-pop-up state, and triggering a preset voice assistant based on the voice static broadcast so as to start a second recording function of the voice assistant.
Optionally, the non-ejection module comprises:
and the non-pop-up unit is used for generating a voice assistant exclusive symbol based on the voice trigger event if the input method state is a non-pop-up state, and generating a voice static broadcast according to the voice assistant exclusive symbol and the voice trigger event.

and the release module is used for releasing the memory resource occupied by the voice assistant if the second recording function does not acquire any voice interaction event within the preset time length.
