In particular, as the technology of electronic devices is developed, the fields in which the electronic devices are applied are becoming wider, for example, more and more electronic devices are beginning to be applied to the field of video recording. At present, when video recording is performed by using electronic equipment, the video recording is triggered and executed mainly through touch operation of a user, so that the problems of complex operation and poor user experience are caused. In order to solve the above problems, current manufacturers of electronic devices start to support voice commands to control video recording, so as to reduce the tedious steps of touch operations and improve the video recording experience of users, however, the inventors have found through research that the voice commands supported by the current electronic devices only include the voice commands related to video recording start, and in the process that the electronic devices are in a video recording mode, the video recording trigger can be realized only through the touch operations.
In view of the above problems, the inventors have found through long-term research and provide a video recording method, a device, an electronic device, and a storage medium provided in the embodiments of the present application, where the received voice instruction is subjected to intention analysis when the electronic device is in a video recording mode, and a video recording mode corresponding to the intention is obtained to adjust video recording parameters, so as to simplify user operations in a video recording scene and improve video recording experience of a user. The specific video recording method is described in detail in the following embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a video recording method according to an embodiment of the present application. The video recording method is used for analyzing the intention of the received voice command and acquiring the video recording mode corresponding to the intention to adjust the video recording parameters in the process that the electronic equipment is in the video recording mode, so that the user operation is simplified in the video recording scene, and the video recording experience of the user is improved. In an embodiment, the video recording method is applied to the video recording apparatus 200 shown in fig. 6 and the electronic device 100 (fig. 7) equipped with the video recording apparatus 200. The specific process of the present embodiment will be described below by taking an electronic device as an example, and it is understood that the electronic device applied in the present embodiment may be a smart phone, a tablet computer, a wearable electronic device, and the like, which is not limited herein. As will be described in detail with respect to the flow shown in fig. 1, the video recording method may specifically include the following steps:
step S110: and receiving a voice instruction and acquiring a processing intention corresponding to the voice instruction in the process that the electronic equipment is in a video recording mode.
In some embodiments, a user may input a video recording start instruction at the electronic device, and the electronic device may start a video recording function and be in a video recording mode in response to the video recording start instruction. When the electronic equipment receives a video recording starting instruction input by a user in a text form, the electronic equipment can respond to the video recording starting instruction to start a video recording function and is in a video recording mode; when the electronic equipment receives a video recording starting instruction input by a user in a voice form, the electronic equipment can respond to the video recording starting instruction to start a video recording function and is in a video recording mode; when the electronic equipment receives the click operation of the user on the application icon corresponding to the video recording application, the electronic equipment can respond to the click operation on the application icon to start a video recording function and is in a video recording mode; when the electronic equipment receives the click operation of the user on the application link corresponding to the video recording application, the electronic equipment can respond to the click operation on the application link to start a video recording function and is in a video recording mode; when the electronic device receives a click operation of a control, which is used by a user for recording a video, for an available camera in other application programs, the electronic device may respond to the click operation of the control for the available camera to start a video recording function, and may be in a video recording mode, and the like, which is not limited herein.
In some embodiments, the camera activated by the electronic device may be a front camera, a rear camera, a camera hidden in the body of the electronic device and rotatable with respect to the body of the electronic device, and the like, which is not limited herein.
In this embodiment, in the process that the electronic device is in the video recording mode, the voice instruction may be received, and the received voice instruction may be analyzed to obtain the processing intention corresponding to the voice instruction. In some embodiments, during the video recording mode of the electronic device, the voice command may be received in real time, at preset time intervals, at a specified time, or in other preset manners, which is not limited herein. In some embodiments, the electronic device may directly respond to the voice command to obtain the processing intent corresponding to the voice command when receiving the voice command in the shooting mode, or may perform voiceprint recognition on the voice command when receiving the voice command in the video recording mode, and obtain the processing intent corresponding to the voice command when the voiceprint recognition is successful.
Taking as an example that when a voice command is received, the voice print recognition is performed on the voice command, and when the voice print recognition is successful, the processing intention corresponding to the voice command is obtained. The electronic device may pre-acquire and store voiceprint information of a valid user as specified voiceprint information, where the specified voiceprint information is used as a judgment basis for the voiceprint information corresponding to the acquired voice command, that is, when it is determined that the voiceprint information corresponding to the voice command matches the specified voiceprint information, it may be determined that the user corresponding to the voice command is a valid user of the electronic device, and when it is determined that the voiceprint information corresponding to the voice command does not match the specified voiceprint information, it may be determined that the user corresponding to the voice command is not a valid user of the electronic device, therefore, in this embodiment, when the electronic device is in the video recording mode, when the voice command is received, it may perform voiceprint extraction on the voice command, acquire the voiceprint information corresponding to the voice command, and match the voiceprint information corresponding to the voice command with the specified voiceprint information, when the voiceprint information corresponding to the voice instruction is matched with the specified voiceprint information, the user corresponding to the voice instruction can be determined to be a legal user of the electronic device, and then the processing intention corresponding to the voice instruction can be obtained.
In some embodiments, after receiving the voice instruction, the electronic device may recognize the voice instruction and perform intent analysis to obtain a processing intent corresponding to the voice instruction. The processing intent corresponding to the voice instruction is used for reflecting the processing that the user desires to perform by the electronic device, for example, the processing intent may include "start video recording", "stop video recording", "time video recording", and the like, which is not limited herein. For example, when the voice instruction is "help me record a video", it may be determined that the processing intent corresponding to the voice instruction is "start video recording", and when the voice instruction is "help me record a video of XX duration", it may be determined that the processing intent corresponding to the voice instruction is "time video recording", and the like, which is not limited herein.
In some embodiments, the voice command may be input to an intention classification model for intention classification, a processing intention corresponding to the voice command may be obtained, an entity in the voice command may be extracted and input to the intention classification model for intention classification, a processing intention corresponding to the voice command may be obtained, an entity in the voice command may be extracted, an entity content of the entity may be obtained based on a knowledge graph, an entity content may be input to the intention classification model for intention classification, a processing intention corresponding to the voice command may be obtained, and the like. The intention classification model can be obtained by training classification models such as an SVM (Support Vector Machine) model, a neural network model or a random forest model, and the user intention classification is realized through Machine learning, so that the accuracy of the user intention classification is effectively improved, and the accuracy of voice recognition is improved.
Step S120: and acquiring a video recording mode corresponding to the processing intention from the voice instruction.
In this embodiment, the processing intent corresponding to the voice instruction is video recording, and includes, for example: start video recording, time video recording, etc. After the processing intention (video recording) corresponding to the voice instruction is acquired, the video recording mode corresponding to the processing intention can be acquired from the voice instruction based on the processing intention.
In some embodiments, assuming that the voice instruction is "help me record one video", it may be determined that the processing intent corresponding to the voice instruction is "start video recording", and a video recording mode corresponding to "video recording" may be acquired from "help me record one video" as "start video recording"; assuming that the voice instruction is "help me record a XX-duration video", it may be determined that the processing intention corresponding to the voice instruction is "timed video recording", and a video recording mode corresponding to "video recording" may be obtained from "help me record a XX-duration video", and is "timed video recording", and the like, which is not limited herein.
Step S130: and setting video recording parameters of the electronic equipment based on the video recording mode.
In this embodiment, after the video recording mode corresponding to the processing intention is acquired from the voice instruction, the video recording parameters of the electronic device may be set based on the video recording mode. In some embodiments, the "video recording start time" of the electronic device may be set based on the video recording mode, "the" video recording timing time "of the electronic device may be set based on the video recording mode," the "video recording visual field range" of the electronic device may be set based on the video recording mode, "the" video recording color parameter "of the electronic device may be set based on the video recording mode, and the like, which are not limited herein.
In some embodiments, the video recording parameter of the electronic device set based on the video recording mode may be a preset fixed value, or may be a different value set according to a different voice instruction, which is not limited herein. When the video recording parameter of the electronic device adjusted based on the video recording mode is a preset fixed value, the video recording parameter of the electronic device set each time may be fixed, for example, if the video recording mode is "timed video recording", the "video recording timing time" of the electronic device may be set according to the preset fixed parameter, and if the preset fixed parameter is T1, the "video recording timing time" of the electronic device is set to T1, which is not limited herein. When the video recording parameters of the electronic device set based on the video recording mode are different values set according to different voice commands, the video recording parameters of the electronic device set each time may be variable, for example, if the video recording mode is "timed video recording" and the voice command is "help me record a video with a time duration of T2", the value T2 may be set according to the voice command, and the "video recording timing time" of the electronic device is set to T2.
Step S140: and recording the video based on the video recording parameter.
In this embodiment, after the video recording parameters of the electronic device are set based on the video recording mode, video recording can be performed based on the video recording parameters. If the processing intention is 'start video recording', the video recording can be carried out in response to the voice instruction and based on the video recording parameter, and when the voice instruction of 'stop video recording' is received, the video recording based on the video recording parameter is stopped. If the processing intention is 'timing video recording', the video recording can be carried out in response to the voice instruction and based on the recording duration in the video recording parameters, and the video recording is stopped when the recording is finished.
In some embodiments, in the process of recording a video based on the video recording parameter, if the user considers that the currently recorded video does not satisfy the video recording requirement, the electronic device may further continue to input a voice instruction to the electronic device, so that the electronic device resets the video recording parameter to obtain the recorded video that better meets the user requirement, and if the user considers that the currently recorded video satisfies the video recording requirement, the electronic device may not perform other operations to keep continuously performing the video, so that the video is controlled by voice in the whole video recording process, thereby simplifying the user operation and improving the video recording experience of the user.
In some embodiments, the electronic device may further control the switching on and off of the front camera and the rear camera based on the received voice instruction, which is not described herein again.
According to the video recording method provided by one embodiment of the application, in the process that the electronic equipment is in the video recording mode, the voice instruction is received, the processing intention corresponding to the voice instruction is obtained, the video recording mode corresponding to the processing intention is obtained from the voice instruction, the video recording parameters of the electronic equipment are set based on the video recording mode, and video recording is carried out based on the video recording parameters.

In this embodiment, when it is recognized that the processing intent is not related to video recording, an application corresponding to the processing intent may be acquired. In some embodiments, when it is recognized that the processing intention is not related to video recording, it may be considered that the user desires to implement other tasks that are not related to video recording by voice, and an application corresponding to the other tasks that are not related to video recording may be acquired as the application corresponding to the processing intention. For example, assuming that the processing intent is "view weather", it is not relevant to characterize the processing intent as a video recording, and thus an application corresponding to the processing intent "view weather" may be acquired. For another example, assuming that the processing intent is "view calendar," characterizing the processing intent is not relevant to video recording, and thus, an application corresponding to the processing intent "view calendar" may be acquired.
Step S462: and exiting the video recording mode, and calling the application program corresponding to the processing intention.
In this embodiment, after the application program corresponding to the processing intent is obtained, the video recording mode may be exited, and the application program corresponding to the processing intent is called, so as to automatically switch the application program running in the foreground according to the voice instruction, thereby improving the user experience. In some embodiments, after the application corresponding to the processing intention is acquired, the video recording application may be switched to the background operation of the electronic device, and the application corresponding to the processing intention is operated in the foreground of the electronic device, or after the application corresponding to the processing intention is acquired, the video recording application may be stopped from being operated, and the application corresponding to the processing intention is operated in the foreground of the electronic device.

In some embodiments, after the electronic device invokes the application program corresponding to the processing intention, the electronic device may continue to receive the voice instruction and perform corresponding processing on the application program based on the received voice instruction. In some embodiments, after calling the application program corresponding to the processing intention, the electronic device may receive a touch operation, and perform corresponding processing on the application program based on the received touch operation.
Step S470: not responding to the voice instruction when the processing intent is identified as not being related to video recording.
In this embodiment, the voice instruction may not be responded to when it is recognized that the processing intention is not related to video recording. In some implementations, upon recognizing that the processing intent is not related to video recording, the electronic device may not react and maintain the recording state prior to receiving the voice instruction. In some embodiments, when it is recognized that the processing intention is not related to video recording, a prompt message may be displayed, and the prompt message may be used to prompt a voice command error to instruct the user to re-input a voice command related to video recording, wherein the prompt message may be a voice prompt message, may be a text prompt message, may be a pop-up prompt message, may be a flashing light prompt message, and the like, which are not limited herein.

step S510: and receiving the voice instruction when the electronic equipment is in the process of video recording.
For detailed description of step S510, please refer to step S110, which is not described herein again.
Step S520: and carrying out entity recognition on the voice command to acquire an entity in the voice command.
The entity identification is also called named entity identification (NE), and refers to a process of identifying a specific type of object name or symbol in a voice command. In some embodiments, the electronic device may perform entity recognition on the voice command through named-entity recognition (NER) to obtain an entity in the voice command, so as to solve the problem of context independence caused only by dictionary matching and improve the accuracy of target entity acquisition.
Step S530: and carrying out entity linkage on the entity and the knowledge graph to obtain entity content corresponding to the entity.
The knowledge graph (knowledge graph/utility) is a series of different graphs displaying the relation between the knowledge development process and the structure, the characteristic information corresponding to the knowledge resources is described through a visualization technology, the characteristic information and the mutual relation among the characteristic information are mined, analyzed, constructed, drawn and displayed, and in the knowledge graph, a mesh structure is formed among all the characteristics so as to clearly express the relation among corresponding entities in all the fields and the relation among corresponding classifications of the entities.
The Entity Linking (EL) is used to map entity references in the voice command to a given Knowledge Base (KB), and in this embodiment, to map the entity references to a knowledge graph. In some embodiments, the knowledge-graphs of the respective domains are different, so before the entity and the knowledge-graph are entity-linked, the domain to which the entity belongs may be identified, the knowledge-graph corresponding to the domain to which the entity belongs may be obtained, and then the entity and the knowledge-graph of the corresponding domain may be entity-linked to obtain the entity content corresponding to the entity. For example, if the domain to which the entity belongs is the video recording domain, the knowledge graph of the video recording domain may be obtained, and then the entity and the knowledge graph of the video recording domain are subjected to entity link to obtain the entity content corresponding to the entity.
In some embodiments, the electronic device may entity-link the entity with the knowledge-graph through an entity-linking (NEL) to obtain entity content corresponding to the entity. It can be understood that, in the embodiment, by physically linking the entity with the knowledge graph, compared with the way of identifying and linking the voice command with the knowledge graph, the problem of resource recall can be reduced. In addition, in the embodiment, the NEL module is abstracted, so that the whole architecture can quickly support resource updating, intervention on resource categories and the like without changing the model.
Step S540: and analyzing the intention of the voice instruction based on the entity content to acquire a processing intention corresponding to the voice instruction.
In some embodiments, the entity content may be input into a trained intention classification model, at least one classification result output by the trained intention classification model is obtained, and the at least one classification result is used as a processing intention corresponding to the voice instruction, so as to achieve obtaining of the processing intention corresponding to the voice instruction. Specifically, the trained intention classification model can be obtained by training classification models such as a Support Vector Machine (SVM) model, a neural network model or a random forest model, and the user intention classification is realized through Machine learning, so that the accuracy of the user intention classification is effectively improved, and the accuracy of intelligent question answering is improved. For example, entity content is used as an input of a model input single-layer neural network model, intent classification corresponding to the entity content is used as an output of the single-layer neural network model, and the single-layer neural network model is trained based on multiple groups of the entity content and corresponding intent classification to obtain the intent classification model.
Step S550: and acquiring a video recording mode corresponding to the processing intention from the voice instruction.
Step S560: and setting video recording parameters of the electronic equipment based on the video recording mode.
Step S570: and recording the video based on the video recording parameter.
For the detailed description of steps S550 to S570, refer to steps S120 to S140, which are not described herein again.
In another embodiment of the present application, in a video recording process of an electronic device, a voice instruction is received, the voice instruction is subjected to entity identification, an entity in the voice instruction is obtained, entity link is performed on the entity and a knowledge graph, entity content corresponding to the entity is obtained, intent analysis is performed on the voice instruction based on the entity content, a processing intent corresponding to the voice instruction is obtained, a video recording mode corresponding to the processing intent is obtained from the voice instruction, video recording parameters of the electronic device are set based on the video recording mode, and video recording is performed based on the video recording parameters.
