As shown in fig. 1, according to an embodiment of the present invention, the control method of the voice device includes at least step S110, step S120, step S130, and step S140.
Step S110, after the voice device is awakened, receiving a voice instruction sent by the current user.
For example, the voice device is a voice air conditioner, the awakening word is "air conditioner", the voice air conditioner is awakened when receiving a voice awakening instruction "air conditioner", the voice air conditioner is awakened and then responds to the user, for example, the voice air conditioner responds "please indicate", and waits for receiving a voice instruction sent by the user.
And step S120, determining whether the current voice control scene is a linkage control scene or a local control scene according to the received voice command.
In some embodiments, determining whether the current voice control scenario is a linkage control scenario or a local control scenario according to the received voice command includes: judging whether the received voice instruction is a voice instruction for controlling the voice equipment or a voice instruction for controlling other specified equipment; if the voice command corresponding to the voice equipment is judged, determining the current voice control scene as a local control scene; if the voice command corresponding to the other specified equipment is controlled, judging whether the voice command has a linkage control intention; and if the voice command is judged to have the linkage control intention, determining the current voice control scene as the linkage control scene.
Optionally, the other specified devices include: at least one pre-designated device capable of communicating with the voice device. That is, the belonging voice device is communicatively connected to the other specified device, so that the belonging voice device can control the other specified device to which it is communicatively connected. The voice device is the voice device implemented by the control method, that is, when the control method is implemented on any voice device, the voice device is called the voice device of the control method.
In some embodiments, the other specific device includes: at least one piece of equipment which is pre-designated and is positioned under the same wireless local area network with the voice equipment. Specifically, when at least two devices are in the same wireless local area network, any two devices of the at least two devices can communicate with each other, and the voice device may be any one device of the at least two devices. For example, at least two devices are distributed through a mobile phone APP, so that the at least two devices are distributed in the same wireless local area network.
In some other embodiments, the other specific apparatus includes: and at least one piece of equipment which is specified in advance and communicates with the voice equipment through the server. The voice device may communicate with the server via the internet. Specifically, the voice device and the other specified devices are both bound to the same user account. Optionally, any device bound under the same user account may control other devices bound under the user account through the server. The voice device can control any other device bound under the same user account through the server.
In some other embodiments, the other specific apparatus includes: and at least one pre-designated device which is in communication connection with the voice device in a short-distance wireless communication mode. The short-range wireless communication means includes, for example, bluetooth, WiFi, and/or ZigBee. Optionally, the other specified devices include at least one device that is in the same wireless mesh network as the voice device, where the wireless mesh network includes at least two devices, and any two devices of the at least two devices may communicate in a short-range wireless communication manner. Specifically, the at least two devices are connected in pairs through a wireless communication mode (for example, a WiFi communication mode or a bluetooth communication mode) to form a wireless mesh network, and any two devices can communicate through a short-distance wireless communication mode. For example, the at least two devices form a wireless mesh network through a bluetooth communication mode.
Optionally, the determining whether the received voice instruction is a voice instruction for controlling the voice device or a voice instruction for controlling another specified device may specifically include: the received keywords in the voice command are identified, whether the keywords are the keywords corresponding to the affiliated voice equipment or the keywords corresponding to other appointed equipment are judged, if the keywords are the keywords corresponding to the affiliated voice equipment, the voice command is determined to be the voice command for controlling the affiliated voice equipment, and if the keywords are the keywords corresponding to other appointed equipment, the voice command is determined to be the voice command for controlling other appointed equipment.
For example, the voice device is a voice air conditioner, the wakeup word is "air conditioner", when the voice air conditioner receives a voice wakeup command "air conditioner", the voice air conditioner wakes up the voice air conditioner, after the voice air conditioner is woken up, it responds to the user, for example, the voice air conditioner responds "please indicate", and waits for receiving a voice command sent by the user, after receiving the voice command sent by the user, if the voice command of the user is recognized as "help me to open dehumidifier", it is determined that the voice command is a voice command corresponding to the dehumidifier, it is further determined whether the voice command has a linkage control intention, for example, it is found that a control target device of the voice command has a plurality of same devices or can have extensions of other control intentions to the control target device (for example, if the control target device of the voice command has a corresponding linkage control device, it is determined that the voice command has a linkage control intention), determining that the current voice control scene is a linkage control scene; and if the voice instruction of the user is recognized as 'turn on the air conditioner', determining that the voice instruction is the voice instruction corresponding to the air conditioner, and further determining that the current control scene is the voice equipment control scene.
And step S130, if the current voice control scene is determined to be the linkage control scene, entering a multi-turn dialogue recognition interaction mode.
In some embodiments, the multiple rounds of voice dialog interaction mode includes: identifying a linkage control intention of the voice instruction sent by the current user; performing multi-round voice conversation interaction with the current user according to the identified linkage control intention and a preset multi-round voice conversation rule; and controlling corresponding voice equipment according to the response voice instruction of the current user in the multi-round voice conversation interaction.
Optionally, the multi-round conversation interaction mode can be executed by a cloud server, that is, after receiving a voice instruction of a user each time, the voice device sends the received voice instruction to the cloud server, and the cloud server identifies a linkage control intention of the voice instruction sent by the current user; returning conversation contents or conversation voices according to the recognized linkage control intention and a preset multi-round voice conversation rule, and performing multi-round voice conversation interaction with the current user according to the conversation contents or the conversation voices returned by the cloud server (the voice device); and controlling corresponding voice equipment according to the response voice instruction of the current user in the multi-round voice conversation interaction.
For example, after the voice air conditioner receives a voice instruction of a user, for example, "help me open a dehumidifier", at this time, a plurality of other smart home products have been bound under a user account of the user. After the air conditioner identifies the control intention of the user, the fact that the user has a plurality of same devices or can also have other control intention extensions for the devices is found, at the moment, linkage control of the air conditioner is achieved, and the cloud end automatically triggers a multi-turn conversation identification interaction mode. Or, when the air conditioner detects that the cloud end has other linkage functions (that is, the control target device has corresponding linkage control device) to the dehumidifier device, the air conditioner queries the user that the dehumidifier is better used together with the aromatherapy machine and whether the aromatherapy machine is turned on? At the moment, the user does not need to awaken the voice air conditioner again, the voice command, such as 'help me open the dehumidifier of the living room', and other language command words can be directly supplemented, and the voice air conditioner exits the multi-turn conversation recognition interaction mode after the voice command is successfully executed and/or the multi-turn conversation is finished.
Step S140, if it is determined that the current speech control scene is the local control scene, entering a speech continuous recognition interaction mode.
In some embodiments, the voice continuous recognition interaction mode includes: after receiving a voice instruction, executing the received voice instruction, and receiving the next voice instruction within a preset time; if the next voice instruction is received within the preset time, executing the received voice instruction and continuing to receive the next voice instruction within the preset time, and so on; and if the next voice instruction is not received within the preset time or a preset ending instruction is received within the preset time, exiting the voice continuous recognition interactive mode. The recognition duration (i.e., the preset time) corresponding to the voice continuous recognition interactive mode is longer than the recognition duration of the single-round voice recognition interactive mode, for example, the recognition duration of the single-round voice recognition interactive mode is 10 seconds to 20 seconds, and the recognition duration (i.e., the preset time) of the voice continuous recognition interactive mode may be set to 30 seconds to 40 seconds.
For example, after receiving a voice instruction of a user, for example, "turn on the air conditioner," recognize, determine to enter a local control scenario of the air conditioner, enter a voice continuous recognition interaction mode, at this time, the air conditioner adjusts an original recognition duration, for example, the original duration is 10 seconds to 20 seconds, increases the recognition duration to satisfy other possible control instructions of the user, for example, increases the recognition duration to 30 seconds to 40 seconds, and restarts the recognition state countdown after each recognition response, at this time, the user does not need to wake up the voice air conditioner again, and can directly speak other air conditioner control voice instructions, for example, "cooling mode", "18 degrees", and the like. And if the next voice command is not received after the countdown time is up, exiting the recognition state. When other intention command words are identified, the air conditioner performs a bottom-of-pocket answer (a preset ending instruction) and then moves back to the identification state, and the air conditioner needs to be awakened again for the next identification.
Optionally, after entering the voice continuous recognition interaction mode, if a voice instruction with a linkage control intention is received, entering a multi-round voice conversation interaction mode. For example, when the air conditioner is in the voice continuous recognition interaction mode, the voice continuous recognition state is maintained only in the control scene of the air conditioner local machine, if a voice instruction for controlling other devices is received, it is determined that the voice instruction has an interlocking control intention, and a multi-round voice conversation interaction mode is entered, and a specific implementation manner of the multi-round voice conversation interaction mode may refer to the related specific implementation manner in the foregoing step S130, which is not described herein again.
Fig. 2 is a method diagram of another embodiment of the control method of the voice device provided by the present invention.
As shown in fig. 2, according to another embodiment of the present invention, the control method of the voice device further includes step S150, step S160, and step S170.
And step S150, if the current voice control field is determined to belong to the specific function control field of the equipment according to the received voice command, entering a single-round voice recognition interaction mode.
For example, when the air conditioner recognizes and judges the voice command of the user and then falls into other fields of non-air-conditioning functions, such as a music playing field, the original single-turn voice recognition interaction mode is maintained at the beginning of interaction, and the single-turn voice recognition interaction mode is awakened once and recognized once. When the user needs to adjust the volume of the music after the music is played, the user needs to wake up the air conditioner again.
And step S160, after entering the single-round voice recognition interaction mode, acquiring the voice interaction mode corresponding to the current user in the current voice control field according to the use habit data of the current user.
For example, big data analysis is performed on the use habit data of the current user through the cloud, and a voice interaction mode suitable for the current user is obtained comprehensively. For example, a neural network model for predicting continuous control behaviors of the user in the current speech control field is obtained according to the use habit data of the user, and the next control behavior of the current control behavior of the user can be predicted according to the neural network model. For example, when the cloud finds that the user is in the music playing field, the cloud wakes up the device again with a high probability to perform secondary voice control, and at the moment, the cloud automatically adjusts the recognition mode of the user in the music playing field, so as to customize the optimal recognition interaction mode related to the field.
Step S170, entering the acquired voice interaction mode corresponding to the current user in the current voice control scene.
For example, the air conditioner can carry the unique device code of the device, the MAC of the voice module, and the voice firmware version information when performing each cloud request, so that the cloud can know which device initiates the request when processing each piece of voice request data. The cloud semantic platform exports the use data of the equipment user, and the use data is analyzed in the cloud (for example, the use data is analyzed by running a neural network model), so that a recognition interaction mode suitable for the user is obtained. For example: when the music is played, the user always wakes up the voice air conditioner again to control the air conditioner again, and the cloud end can feel that the voice continuous recognition interactive mode is more suitable for the user than the single-round voice recognition interactive mode.
In order to clearly illustrate the technical solution of the present invention, the following describes the execution flow of the control method of the voice device provided by the present invention in different scenarios with some specific embodiments.
Fig. 3 is a schematic method diagram of a specific embodiment of a control method of a voice device in different voice interaction scenarios. As shown in fig. 3, taking a voice air conditioner as an example, the voice air conditioner determines whether the current voice control scene is a local control scene, a linkage control scene or another scene (a specific function control field), if the current voice control scene is the local control scene, the voice continuous recognition interaction mode is entered, if the current voice control scene is the linkage control scene, the multi-turn dialogue voice interaction mode is entered, and if the current voice control scene is the other scene (the specific function control field), the single-turn voice recognition interaction mode is adopted or the customized voice interaction mode is obtained.
Fig. 4 is a schematic method diagram of an embodiment of the control method of the speech device in the continuous speech recognition interaction mode according to the present invention. As shown in fig. 4, taking a voice air conditioner as an example, after a user wakes up the voice air conditioner, the voice air conditioner enters a continuous voice recognition interaction mode, the voice air conditioner continuously recognizes a voice instruction of the user, executes a corresponding control instruction after recognizing a voice instruction, and receives a next voice instruction within a preset time, if the next voice instruction is received within the preset time, executes a corresponding control command, and continues to receive the next voice instruction within the preset time, and if the next voice instruction is not received within the preset time, exits the continuous recognition interaction mode.

For example, the at least two devices form a wireless mesh network through a bluetooth communication mode.
Optionally, the determining whether the received voice instruction is a voice instruction for controlling the voice device or a voice instruction for controlling another specified device may specifically include: the received keywords in the voice command are identified, whether the keywords are the keywords corresponding to the affiliated voice equipment or the keywords corresponding to other appointed equipment are judged, if the keywords are the keywords corresponding to the affiliated voice equipment, the voice command is determined to be the voice command for controlling the affiliated voice equipment, and if the keywords are the keywords corresponding to other appointed equipment, the voice command is determined to be the voice command for controlling other appointed equipment.
For example, the voice device is a voice air conditioner, the wakeup word is "air conditioner", when the voice air conditioner receives a voice wakeup command "air conditioner", the voice air conditioner wakes up the voice air conditioner, after the voice air conditioner is woken up, it responds to the user, for example, the voice air conditioner responds "please indicate", and waits for receiving a voice command sent by the user, after receiving the voice command sent by the user, if the voice command of the user is recognized as "help me to open dehumidifier", it is determined that the voice command is a voice command corresponding to the dehumidifier, it is further determined whether the voice command has a linkage control intention, for example, it is found that a control target device of the voice command has a plurality of same devices or can have extensions of other control intentions to the control target device (for example, if the control target device of the voice command has a corresponding linkage control device, it is determined that the voice command has a linkage control intention), determining that the current voice control scene is a linkage control scene; and if the voice instruction of the user is recognized as 'turn on the air conditioner', determining that the voice instruction is the voice instruction corresponding to the air conditioner, and further determining that the current control scene is the voice equipment control scene.
The control unit 130 is configured to enter a multi-round voice conversation interaction mode if the current voice control scene of the determination unit 120 is a linkage control scene; if the determining unit 120 determines that the current speech control scene is the local control scene, it enters a speech continuous recognition interaction mode.
In some embodiments, the multiple rounds of voice dialog interaction mode includes: identifying a linkage control intention of the voice instruction sent by the current user; performing multi-round voice conversation interaction with the current user according to the identified linkage control intention and a preset multi-round voice conversation rule; and controlling corresponding voice equipment according to the response voice instruction of the current user in the multi-round voice conversation interaction.
Optionally, the multi-round conversation interaction mode can be executed by a cloud server, that is, after receiving a voice instruction of a user each time, the voice device sends the received voice instruction to the cloud server, and the cloud server identifies a linkage control intention of the voice instruction sent by the current user; returning conversation contents or conversation voices according to the recognized linkage control intention and a preset multi-round voice conversation rule, and performing multi-round voice conversation interaction with the current user according to the conversation contents or the conversation voices returned by the cloud server (the voice device); and controlling corresponding voice equipment according to the response voice instruction of the current user in the multi-round voice conversation interaction.
For example, after the voice air conditioner receives a voice instruction of a user, for example, "help me open a dehumidifier", at this time, a plurality of other smart home products have been bound under a user account of the user. After the air conditioner identifies the control intention of the user, the fact that the user has a plurality of same devices or can also have other control intention extensions for the devices is found, at the moment, linkage control of the air conditioner is achieved, and the cloud end automatically triggers a multi-turn conversation identification interaction mode. Or, when the air conditioner detects that the cloud end has other linkage functions (that is, the control target device has corresponding linkage control device) to the dehumidifier device, the air conditioner queries the user that the dehumidifier is better used together with the aromatherapy machine and whether the aromatherapy machine is turned on? At the moment, the user does not need to awaken the voice air conditioner again, the voice command, such as 'help me open the dehumidifier of the living room', and other language command words can be directly supplemented, and the voice air conditioner exits the multi-turn conversation recognition interaction mode after the voice command is successfully executed and/or the multi-turn conversation is finished.
The control unit 130 is configured to enter a multi-round voice conversation interaction mode if the current voice control scene of the determination unit is a linkage control scene; and if the current voice control scene is determined to be the local control scene, entering a voice continuous recognition interaction mode.
In some embodiments, the voice continuous recognition interaction mode includes: after receiving a voice instruction, executing the received voice instruction, and receiving the next voice instruction within a preset time; if the next voice instruction is received within the preset time, executing the received voice instruction and continuing to receive the next voice instruction within the preset time, and so on; and if the next voice instruction is not received within the preset time or a preset ending instruction is received within the preset time, exiting the voice continuous recognition interactive mode. The recognition duration (i.e., the preset time) corresponding to the voice continuous recognition interactive mode is longer than the recognition duration of the single-round voice recognition interactive mode, for example, the recognition duration of the single-round voice recognition interactive mode is 10 seconds to 20 seconds, and the recognition duration (i.e., the preset time) of the voice continuous recognition interactive mode may be set to 30 seconds to 40 seconds.
For example, after receiving a voice instruction of a user, for example, "turn on the air conditioner," recognize, determine to enter a local control scenario of the air conditioner, enter a voice continuous recognition interaction mode, at this time, the air conditioner adjusts an original recognition duration, for example, the original duration is 10 seconds to 20 seconds, increases the recognition duration to satisfy other possible control instructions of the user, for example, increases the recognition duration to 30 seconds to 40 seconds, and restarts the recognition state countdown after each recognition response, at this time, the user does not need to wake up the voice air conditioner again, and can directly speak other air conditioner control voice instructions, for example, "cooling mode", "18 degrees", and the like. And if the next voice command is not received after the countdown time is up, exiting the recognition state. When other intention command words are identified, the air conditioner performs a bottom-of-pocket answer (a preset ending instruction) and then moves back to the identification state, and the air conditioner needs to be awakened again for the next identification.
Optionally, the control unit 130 is further configured to: after entering the voice continuous recognition interaction mode, if a voice command with a linkage control intention is received, entering a multi-round voice conversation interaction mode. For example, when the air conditioner is in the voice continuous recognition interaction mode, the voice continuous recognition state is maintained only in the control scene of the air conditioner local machine, if a voice instruction for controlling other devices is received, it is determined that the voice instruction has an interlocking control intention, and a multi-round voice conversation interaction mode is entered, and a specific implementation manner of the multi-round voice conversation interaction mode may refer to the related specific implementation manner in the foregoing step S120, which is not described herein again.
Fig. 7 is a block diagram of another embodiment of the control device of the speech apparatus according to the present invention. As shown in fig. 7, the control device 100 further includes an acquisition unit 140.
The control unit 130 is further configured to: if the current voice control scene is determined not to be the linkage control scene or the local control scene according to the received voice command, entering a single-wheel voice recognition interaction mode; the obtaining unit 140 is configured to obtain, after entering the single-round voice recognition interaction mode, a voice interaction mode corresponding to the current user in the current voice control scenario according to the usage habit data of the current user; the control unit 130 is further configured to: and entering the acquired voice interaction mode corresponding to the current user in the current voice control scene.
For example, when the air conditioner recognizes and judges the voice command of the user and then falls into other fields of non-air-conditioning functions, such as a music playing field, the original single-turn conversation mode is initially interactively maintained, and the voice command is awakened once and recognized once. When the user needs to adjust the volume of the music after the music is played, the user needs to wake up the air conditioner again.
The obtaining unit 140 performs big data analysis on the use habit data of the current user through a cloud, for example, to comprehensively obtain a voice interaction mode suitable for the current user. For example, a neural network model for predicting continuous control behaviors of the user in the current speech control field is obtained according to the use habit data of the user, and the next control behavior of the current control behavior of the user can be predicted according to the neural network model. For example, when the cloud finds that the user is in the music playing field, the cloud wakes up the device again with a high probability to perform secondary voice control, and at the moment, the cloud automatically adjusts the recognition mode of the user in the music playing field, so as to customize the optimal recognition interaction mode related to the field.
For example, the air conditioner can carry the unique device code of the device, the MAC of the voice module, and the voice firmware version information when performing each cloud request, so that the cloud can know which device initiates the request when processing each piece of voice request data. The cloud semantic platform exports the use data of the equipment user, and the use data is analyzed in the cloud (for example, the use data is analyzed by running a neural network model), so that a recognition interaction mode suitable for the user is obtained. For example: when the music is played, the user always wakes up the voice air conditioner again to control the air conditioner again, and the cloud end can feel that the voice continuous recognition interaction mode is more suitable for the user than the single-round voice interaction mode.
