Detailed Description

In order to make the features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.

It should be further noted that information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data for analysis, stored data, displayed data, etc.), and signals referred to in the embodiments of the present application are authorized by the user or sufficiently authorized by various parties, and the collection, use, and processing of the relevant data requires compliance with relevant laws and regulations and standards in relevant countries and regions. For example, the object characteristics, the interactive behavior characteristics, the user information and the like referred to in the present application are obtained under sufficient authorization.

Voice assistants are an important application of artificial intelligence on electronic devices. The electronic equipment can carry out intelligent dialogue and intelligent interaction of instant question and answer with the user through the voice assistant. And a voice command input by the user can be recognized, and the electronic equipment is triggered to automatically execute an event corresponding to the voice command. Typically, the voice assistant is in a sleep state, and the user can wake up the voice assistant by voice before using the voice assistant. Only after the voice assistant is awakened can the voice command input by the user be received and recognized. The voice data for waking up may be referred to as a wake-up word, for example, taking the wake-up word as "small cloth", if the user wants to query the weather of the place a using the voice assistant, a voice command of "small cloth, weather of the place a" may be spoken, and after the voice assistant receives the semantic command, the electronic device may be woken up based on the wake-up word "small cloth", and then the electronic device may recognize the voice command using the voice assistant, and trigger the electronic device to query the weather of the place a, and report the weather of the place a to the user by voice or text.

In the related art, the application of voice control is more and more widespread as the technology is developed. For example, many home devices currently support voice control functions. For example, a voice assistant can be installed in the home equipment to implement a voice control function. Thus, there may be a scenario in which the user is located in an environment (e.g., the user's home) that includes multiple devices that support voice control functionality, i.e., a multiple device scenario. In the multi-device scenario, if there are devices with the same wake-up word in the multiple devices, after the user speaks the wake-up word, the voice assistants of the devices with the same wake-up word are all woken up, and all recognize and respond to the voice command spoken subsequently by the user.

Referring to fig. 1, fig. 1 is a diagram illustrating an apparatus interaction method in the related art according to an embodiment of the present disclosure.

As shown in fig. 1, a living room of a user is taken as a multi-device scene, wherein the living room of the user has four devices, namely a sound box 101, a television 102, a mobile phone 103 and a wearable watch 104, the four devices are all provided with a voice assistant, and wakeup words are all small cloths. Then after the user speaks a voice control command containing the wake-up word "duffel", the speaker 101, the television 102, the cell phone 103, and the voice assistant wearing the watch 104 are all woken up and recognize the voice command, and recognize and respond to the voice command.

In a multi-device scenario, a user may only need one device to respond, for example, when the user is using a mobile phone, if the user needs to perform voice interaction with a voice assistant, the user often wants the voice assistant in the mobile phone to be woken up and respond to a control command of the user to perform voice interaction because the interaction with the mobile phone is more convenient, and if multiple devices respond simultaneously, the experience brought to the user is poor.

In order to solve the technical problem, in the embodiment of the application, when it is monitored that the voice of a user meets a voice awakening condition, whether the current equipment is in a first preset equipment state is judged; then if the current equipment is in a first preset equipment state, sending first equipment state information corresponding to the first preset equipment state to candidate equipment, wherein the candidate equipment and the current equipment are in the same multi-equipment scene; and finally, if second equipment state information sent by the candidate equipment is received, determining whether the current equipment carries out voice interaction or not according to the first preset equipment state and a second preset equipment state corresponding to the second equipment state information. When the situation that the voice of the user meets the voice awakening condition is monitored, the first preset device state of the current device and the second preset device state of the candidate device can be obtained, and the device states can represent the use condition of the user on the device, so that which device the user specifically wants to use for voice interaction can be determined according to the device states of the devices, and the accuracy of voice control is effectively improved.

Referring to fig. 2, fig. 2 is a diagram illustrating an exemplary system architecture of a voice control method according to an embodiment of the present application.

As shown in fig. 2, the system architecture may include an electronic device 201, a network 202, and a server 203. The network 202 is used to provide a medium for communication links between the electronic device 201 and the server 203. Network 202 may include various types of wired or wireless communication links, such as: the wired communication link includes optical fiber, twisted pair wire or coaxial cable, and the Wireless communication link includes bluetooth communication link, wireless-Fidelity (Wi-Fi) communication link or microwave communication link.

The electronic device 201 may interact with the server 203 via the network 202 to receive messages from the server 203 or to send messages to the server 203, or the electronic device 201 may interact with the server 203 via the network 202 to receive messages or data sent by other users to the server 203. The electronic device 201 may be hardware or software. When the electronic device 201 is hardware, it may be a variety of electronic devices including, but not limited to, smart watches, smart phones, tablets, smart televisions, laptop portable computers, desktop computers, and the like. When the electronic device 201 is software, it may be installed in the electronic device listed above, and it may be implemented as multiple software or software modules (for example, for providing distributed services), or may be implemented as a single software or software module, and is not limited in this respect.

The server 203 may be a business server providing various services. The server 203 may be hardware or software. When the server 203 is hardware, it may be implemented as a distributed server cluster composed of a plurality of servers, or may be implemented as a single server. When the server 203 is software, it may be implemented as a plurality of software or software modules (for example, to provide distributed services), or may be implemented as a single software or software module, which is not limited herein.

In this embodiment of the application, the number of the electronic devices 201 may be multiple, multiple electronic devices 201 may be in the same multiple device scenario, and the multiple electronic devices 201 in the same multiple device scenario may also be directly connected through the network 202, that is, the multiple electronic devices 201 may also directly perform data transmission based on the network 202. Therefore, the system architecture may not include the server 203, in other words, the server 203 may be an optional device in this embodiment, that is, the method provided by this embodiment may be applied to a system structure that only includes the electronic device 201, and this is not limited in this embodiment of the application.

In this embodiment of the application, if a certain electronic device 201 in the system architecture is used as a current device, if the current device monitors that a user voice meets a voice wake-up condition, it is determined whether the current device is in a first preset device state, and if the current device is in the first preset device state, first device state information corresponding to the first preset device state is sent to a candidate device, where the candidate device and the current device are in a same multi-device scene; and if second equipment state information sent by the candidate equipment is received, determining whether the current equipment carries out voice interaction or not according to the first preset equipment state and a second preset equipment state corresponding to the second equipment state information.

It should be understood that the number of electronic devices, networks, and servers in fig. 2 is merely illustrative, and that any number of electronic devices, networks, and servers may be used, as desired for an implementation.

Referring to fig. 3, fig. 3 is a schematic flowchart of a voice control method according to an embodiment of the present disclosure. The execution subject of the embodiment of the present application may be an electronic device that executes the voice control, a processor in the electronic device that executes the voice control method, or a voice control service in the electronic device that executes the voice control method. For convenience of description, a specific implementation process of the voice control method is described below by taking an example in which the implementation subject is a processor in an electronic device.

As shown in fig. 3, the voice control method may include at least:

s302, when the condition that the voice of the user meets the voice awakening condition is monitored, whether the current equipment is in a first preset equipment state is judged.

It can be understood that, in the embodiment of the present application, the voice control method is mainly applied to a multi-device scenario, where at least two electronic devices exist in the multi-device scenario, each electronic device in the same multi-device scenario belongs to the same device group, the electronic devices in the same device group have the same device class (that is, the electronic devices in the same device group do not distinguish a subordinate relationship or a primary-secondary relationship), and data transmission may be performed directly between the electronic devices or performed based on data forwarding of a server. Furthermore, each electronic device can be in the same multi-device scene by connecting the same wireless access point (such as a WiFi access point), logging in the same user account, and the like.

Furthermore, each electronic device in the same multi-device scenario is provided with a program similar to a voice assistant, and the program can monitor user voice sent by users around the electronic device in real time based on voice data collected by a microphone, and judge whether the users need to perform voice interaction.

A mode for judging whether a user needs to perform voice interaction is to set voice awakening conditions in each electronic device in advance, and if the situation that the voice of the user meets the voice awakening conditions is monitored, the user can be confirmed to perform voice interaction. In this embodiment of the application, the voice wake-up condition may be that the voice of the user includes a preset wake-up word and/or a voiceprint corresponding to the voice of the user is a preset voiceprint, so that after the voice of the user is collected by the voice assistant through the microphone, the voice wake-up word detection and/or the voiceprint detection may be performed based on the voice of the user, and when the voice of the user includes the preset wake-up word and/or the voiceprint corresponding to the voice of the user is the preset voiceprint, it may be considered that the voice of the user is detected to satisfy the voice wake-up condition. The voice wake-up condition may also be that the electronic device is in a preset state, for example, if the electronic device is a smart watch, and in order to reduce power consumption, the smart watch is in a screen-off state most of the time, and then if the smart watch is in a screen-on state, it may be determined that the smart watch satisfies the voice wake-up condition.

Since the device state of the electronic device changes when the user uses the electronic device or performs related operations on the electronic device, for example, the device state may refer to a static or dynamic state such as a device placement state, a screen lighting state, a standby state, a video playing state, and the like, the device state of the electronic device is associated with the operations of the user, and therefore, when the user needs to perform voice interaction in a multi-device scene, the user often prefers the electronic device that is operating to respond.

Based on the above thought, in this application embodiment, each electronic device that can be in the same multi-device scene can all judge whether self equipment is in the preset device state at first when detecting that user's voice satisfies the voice wake-up condition.

Specifically, for each electronic device in the same multi-device scenario, if the types of the electronic devices are different, the corresponding preset states of the electronic devices are also different, so that the preset device states corresponding to the different electronic devices can be set according to the device type of each electronic device in advance, and then if the electronic device is in the preset device state, it represents that the electronic device may be operated or used by a user, and further, the possibility that the user needs to interact with the electronic device is higher, in order to distinguish the preset device states of the different devices, in this embodiment of the present application, the preset device state corresponding to the current device is determined as the first preset device state.

For the current device, if the current device monitors that the user voice satisfies the voice wake-up condition, it may be determined whether the current device is in a first preset device state, where a manner of determining whether the current device is in the first preset device state may not be limited, for example, it may be determined whether the current device is in the first preset device state by obtaining data collected by a preset sensor in the current device.

S304, if the current equipment is in a first preset equipment state, sending first equipment state information corresponding to the first preset equipment state to candidate equipment, wherein the candidate equipment and the current equipment are in the same multi-equipment scene.

If it is determined that the current device is in the first preset device state, it may be determined that the current device is possibly a device that is being used or operated by a user, but since a plurality of electronic devices exist in a multi-device scene, other electronic devices that are also in the preset device state may also exist in the multi-device scene, so that it is convenient to determine an electronic device that the user wants to perform voice interaction from the plurality of electronic devices that are in the preset device state, after determining that the electronic device is in the preset device state, the electronic devices that are in the same multi-device scene may synchronize state information corresponding to the preset device state that the electronic device is in to the other electronic devices.

Further, since the preset device state is not entity data and cannot be directly transmitted, the current device may obtain first device state information representing the first preset device state, and send the first device state to at least one candidate device in the same multi-device scenario as the current device, where the candidate device may be all electronic devices in the same multi-device scenario as the current device or an electronic device designated by a user in the same multi-device scenario as the current device.

S306, if second equipment state information sent by the candidate equipment is received, whether the current equipment carries out voice interaction or not is determined according to the first preset equipment state and a second preset equipment state corresponding to the second equipment state information.

Since multiple electronic devices exist in the multi-device scene, there may also exist other electronic devices in the preset device state in the multi-device scene, that is, when the current device sends the first device state information corresponding to the first device state to the candidate device, it is possible that the candidate device also sends the device state information of the preset device state corresponding to the candidate device, here, in order to distinguish the current device from the first preset device state in which the current device is located, in the embodiment of the present application, the preset device state in which the candidate device is located is marked as the second preset device state, then after the first device state information corresponding to the first preset device state of the current device is sent to the candidate device, the current device may wait for the first preset time, and if the second device state information sent by at least one candidate device is received within the first preset time, it represents that there may also exist other electronic devices in the preset device state in the multi-device scene.

Further, after receiving second device state information sent by at least one candidate device, second preset device states corresponding to the candidate devices may be respectively determined according to the second device state information, and then, whether the current device performs voice interaction is determined according to comparison between the first preset device state and the second preset device states. The manner of comparing the first preset device state with each second preset device state may not be limited, and the comparison may be performed according to a rule set by a user or the electronic device when the electronic device leaves a factory, so as to determine a comparison result. If the current equipment is determined to carry out voice interaction, the voice control command corresponding to the voice of the user can be analyzed, and the voice control command is responded.

Because each electronic device in the multi-device scene executes the voice control method, one electronic device for voice interaction can be determined from the plurality of electronic devices in the multi-device scene, and the experience of the user in voice interaction is improved.

Referring to fig. 4, fig. 4 is a diagram illustrating an apparatus interaction method according to an embodiment of the present disclosure.

As shown in fig. 4, the living room of the user is taken as a multi-device scene, wherein the living room of the user has four devices, namely, a sound box 101, a television 102, a mobile phone 103 and a wearable watch 104, the four devices are all installed with a voice assistant, and the wakeup words are all "small cloth". After the user speaks the user voice containing the awakening word "small cloth", the sound box 101, the television 102, the mobile phone 103, and the voice assistant wearing the watch 104 may all monitor that the user voice meets the voice awakening condition, then the sound box 101, the television 102, the mobile phone 103, and the watch wearing 104 may respectively determine whether the respective devices are in the preset device states, if the mobile phone 103 determines that the respective devices are in the first preset device state, first device state information corresponding to the first preset device state is sent to the sound box 101, the television 102, and the watch wearing 104, if the mobile phone 103 receives the sound box 101, the television 102, and the watch wearing 104, the mobile phone 103 may compare the first preset device state of the mobile phone 103 with a second device state information corresponding to the second device state information of the other devices, and further determine whether the mobile phone 103 performs voice interaction, then the sound box 101, the television 102, and the watch wearing the watch 104 may also determine whether the respective devices perform voice interaction, and finally determine that the television interaction is performed from the sound box 101, the television 102, the mobile phone 103, and the watch wearing 104.

In fig. 4, the mobile phone 103 determines to perform voice interaction, and then the mobile phone 103 may parse the voice control command corresponding to the user voice and affect the voice control command.

Because the interaction with the mobile phone is more convenient, the user often expects that the voice assistant in the mobile phone can be woken up and respond to the control command of the user to perform voice interaction, and if multiple devices respond simultaneously, the experience brought to the user is poor.

In the embodiment of the application, when the voice of a user is monitored to meet a voice awakening condition, whether the current equipment is in a first preset equipment state is judged; then if the current equipment is in a first preset equipment state, sending first equipment state information corresponding to the first preset equipment state to candidate equipment, wherein the candidate equipment and the current equipment are in the same multi-equipment scene; and finally, if second equipment state information sent by the candidate equipment is received, determining whether the current equipment carries out voice interaction or not according to the first preset equipment state and a second preset equipment state corresponding to the second equipment state information. When the situation that the voice of the user meets the voice awakening condition is monitored, the first preset device state of the current device and the second preset device state of the candidate device can be obtained, and the device states can represent the use condition of the user on the device, so that which device the user specifically wants to use for voice interaction can be determined according to the device states of the devices, and the accuracy of voice control is effectively improved.

Referring to fig. 5, fig. 5 is a schematic flow chart of a voice control method according to another embodiment of the present application. As shown in fig. 5, the voice control method may include at least:

s502, when the situation that the voice of the user meets the voice awakening condition is monitored, whether the current equipment is in a first preset equipment state or not is judged.

When a user uses electronic equipment or performs related operations on the electronic equipment, the use or operation modes of different types of electronic equipment are different, so that the preset equipment states of the different types of electronic equipment are different, and therefore, in the process of judging whether the current equipment is in the first preset equipment state, a feasible implementation manner is that the equipment type of the current equipment can be obtained firstly, the equipment type is used for distinguishing the types of the different equipment, for example, the equipment type can be divided into handheld equipment, wearable equipment, sound box equipment, television equipment and the like, and the equipment type can be divided according to the needs of the user or can be directly divided when the user leaves a factory; then, the preset device states corresponding to the electronic devices of different device types are also different, for example, when the device type of the electronic device is a handheld device, the corresponding preset device state may be a handheld state; when the device type of the electronic device is the wearable device, the corresponding preset device state can be a limb lifting state; when the device type of the electronic device is a sound box device, the corresponding preset device state can be a music playing state; when the device type of the electronic device is a television device, the corresponding preset device state may be a video playing state or the like.

Further, some state parameters of the device in different device states are different, so that the specified state parameter corresponding to the current device can be obtained according to the device type of the current device, wherein the specified state parameter can be obtained through a specified sensor and other devices, and finally, whether the current device is in the first preset device state or not is judged according to the specified state parameter.

For example, if the device type of the current device is a handheld device, for example, the current device is a smart phone, then for the handheld device, if the user is using or operating the handheld device, the handheld device is generally not blocked by objects such as a pocket, the handheld device is not completely horizontal, and the handheld device is not very stable, so that if the device type of the current device is the handheld device, at least one of a blocking state parameter, a placing angle state parameter, and a shaking state parameter corresponding to the current device may be obtained, so as to determine whether the current device is in a handheld state according to at least one of the blocking parameter, the placing angle state parameter, and the shaking parameter.

Specifically, if it is determined whether the current device is in the handheld state according to the shielding parameter, the placement angle parameter, and the shaking parameter, it may be determined whether the current device is shielded based on the shielding state parameter, where the shielding state parameter may include an illumination value acquired by the illumination sensor and an approach distance value acquired by the approach sensor, and if the illumination value is smaller than a preset illumination value and the approach distance value is smaller than a preset approach distance value, it may be determined that the current device is shielded, that is, it is determined that the current device is not in the handheld state (the first preset device state); if the angle calculated based on the geomagnetic value and the acceleration value is smaller than the preset flat angle, the current equipment can be determined to be in the flat state, that is, the current equipment is determined not to be in the handheld state (the first preset equipment state); otherwise, it may be determined that the current device is not in a flat state, and whether the current device is in a shaking state may be determined based on shaking state parameters, where the shaking state parameters may include an angular velocity value acquired by an angular velocity sensor, an average angular velocity value within a time sliding window may be calculated according to the angular velocity value, if the current real-time angular velocity value is greater than a preset maximum angular velocity value, or the current real-time angular velocity value is greater than a preset minimum angular velocity value, less than a preset maximum angular velocity value, and the average angular velocity value is greater than a preset average angular velocity value, it may be determined that the current device is in a shaking state, and it may be determined that the current device is in a handheld state (a first preset device state), and if not, it may be determined that the current device is not in a shaking state, it may be determined that the current device is not in a handheld state (a first preset device state).

S504, if the current device is in a first preset device state, first device state information corresponding to the first preset device state is sent to the candidate device, and the candidate device and the current device are in the same multi-device scene.

Step S504 can refer to the description of step S304, and is not described herein.

S506, if second equipment state information sent by the candidate equipment is received, comparing the priority of the first preset equipment state with the priority of the second preset equipment state corresponding to the second equipment state information, and determining whether the current equipment carries out voice interaction or not according to the priority comparison result.

In this embodiment of the present application, after receiving second device status information sent by a candidate device, a first preset device status may be compared with a second preset device status corresponding to the second device status information, and in the comparison process, a feasible implementation manner may be that the first preset device status and priorities of the second preset device statuses are respectively determined, and then whether the current device performs voice interaction is determined according to a priority comparison result.

Specifically, a priority order of preset device states corresponding to electronic devices in the same multi-device scenario may be preset according to an instruction of a user or when the devices leave a factory, then a first state priority corresponding to a first preset device state is determined according to the preset device state priority order, a second state priority corresponding to a second preset device state corresponding to second device state information is determined, and if the first state priority is greater than the second state priority, which represents that the current device has a voice interaction control right with a higher priority, the current device is determined to perform voice interaction; and if the priority of the first state is smaller than that of the second state, representing that other candidate equipment has the voice interaction control right with higher priority, determining that the current equipment does not carry out voice interaction.

S508, if the second equipment state information sent by the candidate equipment is not received, the current equipment is determined to carry out voice interaction.

If the current device does not receive the second device state information sent by the candidate device within the first preset time, which represents that the candidate device in the preset device state does not exist in the multi-device scene, the voice interaction priority of the current device can be directly determined at the moment, and the current device is controlled to perform voice interaction.

And S510, if the current equipment is not in the first preset equipment state and receives second equipment state information sent by the candidate equipment, determining that the current equipment does not carry out voice interaction.

If the current device is not in the first preset device state, but receives the second device state information sent by the candidate device, which represents that the candidate device in the preset device state exists in the multi-device scene, the voice interaction priority of the candidate device is high, and the current device can be controlled not to perform voice interaction.

If the current device is not in the first preset device state and does not receive the second device state information sent by the candidate device, which represents that the interaction priority of all electronic devices in the multi-device scene is lower, each electronic device may not perform voice interaction, and continue to monitor whether the voice of the user meets the wake-up condition, or continue to screen the electronic devices performing voice interaction from all electronic devices in the multi-device scene through other determination conditions.

In the embodiment of the application, whether each electronic device meets the preset device state or not is determined by comparing the device types of each electronic device in the multi-device scene, and then the priority of the preset device state of each electronic device in the multi-device scene is determined to determine whether the current device performs voice interaction or not, so that the accuracy of judging the voice interaction device can be improved.

Referring to fig. 6, fig. 6 is a flowchart illustrating a voice control method according to another embodiment of the present application. As shown in fig. 6, the voice control method may include at least:

s602, when it is monitored that the voice of the user meets the voice awakening condition, judging whether the current equipment is in a first preset equipment state or not.

And S604, if the current equipment is in a first preset equipment state, sending first equipment state information corresponding to the first preset equipment state to candidate equipment, wherein the candidate equipment and the current equipment are in the same multi-equipment scene.

S606, if second equipment state information sent by the candidate equipment is received, whether the current equipment carries out voice interaction or not is determined according to the first preset equipment state and a second preset equipment state corresponding to the second equipment state information.

With regard to steps S602 to S606, reference may be made to the description in the above embodiments, which are not repeated herein.

S608, if the current device is not in the first preset device state and does not receive the second device state information sent by the candidate device, obtaining a first general voice characteristic value corresponding to the current device according to the user voice, and sending the first general voice characteristic value to the candidate device.

If the current device is not in the first preset device state and does not receive the second device state information sent by the candidate device, the interaction priority of all electronic devices in the multi-device scene is low, and if one electronic device still needs to be selected for voice interaction at the moment, the electronic device for voice interaction can be selected through the general voice characteristic value corresponding to each electronic device.

The general voice characteristic value is used for representing the awakening priority between the sound source and the equipment, and many factors are used for representing the awakening priority between the sound source and the equipment, so that the awakening priority between the sound source and the equipment can be represented by using the general voice characteristic parameter, that is, the general voice characteristic value can be represented by using various general voice characteristic parameters. It will be readily appreciated that since a user, when interacting with a device in speech, tends to speak the user speech close to and towards the device, generic speech feature parameters may include, but are not limited to: a distance parameter between the sound source and the device and an orientation parameter of the device relative to the sound source.

Specifically, the distance parameter between the sound source and the device can be calculated by the audio energy of the awakening word in the voice of the user, wherein the larger the energy is, the closer the distance is, the smaller the distance parameter between the sound source and the device is, and the awakening priority is higher. Specifically, the audio energy of the wake word needs to reduce the influence of the environmental noise as much as possible, and the Voice Activity Detection (VAD) method can be used to segment the wake word and the environmental noise based on the Voice of the user containing the wake word, and further obtain the energy and duration of the wake word and the energy and duration of the environmental noise, so that the energy of the wake word without the influence of the noise can be calculated as follows:

wherein, the energy and the time length of the awakening word are respectively recorded as es and ts, and the energy and the time length of the environmental noise are respectively recorded as en and tn, so

Can be considered as the power of the wake-up word,

can be regarded as the power of the ambient noise, then

And

the difference can be regarded as the power of the awakening word without the influence of noise, and then the energy of the awakening word without the influence of noise can be represented by the power of the awakening word without the influence of noise.

Further, the method for calculating the orientation parameter of the current device relative to the sound source may train a decision model of sound orientation through pre-recorded audio data, and then input the user voice into the decision model to obtain a sound orientation result, that is, the orientation parameter of the current device relative to the sound source, where the pre-recorded audio data may include: 1. the reason for selecting the spectral feature data is that the sound source has an increased orientation parameter for the sound source, and the sound will be reflected more to the current device, so that the high frequency part of the user speech received by the current device will be attenuated more than the low frequency part. 2. The reason why the reverberation characteristic data is selected is that if the sounding source increases the orientation parameter of the sounding source to the sounding source, the larger the reverberation energy is, the current device can calculate the voice direct-mixing ratio and autocorrelation characteristic of the user voice, and if the reverberation is larger, the more the peaks of the autocorrelation result are. 3. The reason for selecting the multi-microphone characteristic data is that if the current equipment has a plurality of microphones to participate in the control of voice, the sound direction characteristics of the plurality of microphones can be calculated to assist in deciding the orientation parameters of the current equipment relative to the sound source.

Further, since the number of the first general-purpose speech feature parameters may be multiple, the influence of different first general-purpose speech feature parameters on the wake-up priority between the sound source and the device is different, and therefore, the preset first general-purpose speech feature weight corresponding to each first general-purpose speech feature parameter is set, where the larger the influence of the first general-purpose speech feature parameters on the wake-up priority between the sound source and the device is, the larger the corresponding first general-purpose speech feature weight is. For example, if the first generic speech feature parameters include: the distance parameter between the sound source and the current device and the orientation parameter of the current device relative to the sound source may be set to 0.6 for the first general speech feature weight corresponding to the distance parameter between the sound source and the current device, and 0.4 for the first speech feature weight corresponding to the orientation parameter of the current device relative to the sound source.

Then, after the first general voice feature parameter corresponding to the current device is obtained, a first general voice feature weight corresponding to each first general voice feature parameter may also be obtained, and then, based on each first general voice feature parameter and each first general voice feature weight, a first general voice feature value corresponding to the current device is calculated, that is, each first general voice feature parameter is multiplied by the corresponding first general voice feature weight, and each multiplication result is added as the first general voice feature value corresponding to the current device.

Further, after the first general-purpose speech feature value corresponding to the current device is obtained according to the user speech, the first general-purpose speech feature value needs to be synchronized to other electronic devices in the multi-device scenario, and similarly, other electronic devices in the multi-device scenario also obtain a second general-purpose speech feature value corresponding to the user speech by using the same method as the current device, and synchronize the second general-purpose speech feature value to the current device.

S610, if the second universal voice characteristic value sent by the candidate equipment is received, whether the current equipment carries out voice interaction or not is determined according to the first universal voice characteristic value and the second universal voice characteristic value.

In this embodiment of the application, after the current device sends the first general-purpose speech feature value to all candidate devices in the multi-device field, the current device may wait for a second preset time, and if at least one candidate device receives the second general-purpose speech feature value sent by the candidate device within the second preset time, the current device may determine whether to perform speech interaction according to the first general-purpose speech feature value and the second general-purpose speech feature value, that is, the first general-purpose speech feature value and the second general-purpose speech feature value are compared, and according to a comparison result.

Specifically, the first general voice feature value and the second general voice feature value may be compared, and if the first general voice feature value is greater than the second general voice feature value and represents that the current device has a higher interaction priority with the user, it is determined that the current device performs voice interaction; if the first general voice characteristic value is smaller than the second general voice characteristic value, the current equipment does not have the interaction priority higher than that of the user, namely other candidate equipment has the interaction priority higher than that of the user, and then the current equipment is determined not to carry out voice interaction; if the first universal voice characteristic value is equal to the second universal voice characteristic value, which means that the current device and other candidate devices do not have a higher interaction priority, it may be determined whether the current device is a preset priority interaction device, where the priority interaction device is set by a user in a self-defined manner or set when the electronic device leaves a factory, so that when the universal voice characteristic values of multiple devices are the same, one of the electronic devices is selected for interaction, thereby avoiding a situation that the user fails in voice interaction, and if it is determined that the current device is the preset priority interaction device, it is determined that the current device performs voice interaction.

And S612, if the second communication voice characteristic value sent by the candidate equipment is not received, determining that the current equipment carries out voice interaction.

In this embodiment of the application, after the current device sends the first general speech feature value to all candidate devices in the multi-device field, the current device may wait for a second preset time, and if the second general speech feature value sent by the candidate device is not received within the second preset time, it represents that no other candidate device except the current device in the multi-scene device obtains the general speech feature value, and at this time, the current device may be directly determined to perform speech interaction.

In the embodiment of the application, when it is determined that all electronic devices in a multi-device scene are not in the preset state, the general voice features acquired by all electronic devices for the voice of the user can be acquired respectively, and then the electronic devices for voice interaction are selected according to the general voice features, so that the accuracy of determining the devices for voice interaction is effectively improved.
