[0002] Current offline voice control technology requires a wake word plus a command word for complete control interaction, which is very cumbersome for users. Although wake-up-free technology can save users the trouble of saying a wake word, this technology greatly increases the chance of accidental triggering and may lead to unintended control of the device. Summary of the Invention

[0004] The second objective of this invention is to provide a voice control device for household appliances.

[0005] A third objective of this invention is to provide a computer-readable storage medium.

[0006] The fourth objective of this invention is to provide a household appliance.

[0007] To achieve the above objectives, a first aspect of the present invention provides a voice control method for a household appliance, the method comprising: detecting human activity information within a preset range of the household appliance; controlling the household appliance to execute a command monitoring control strategy when human activity is determined to exist based on the human activity information; and controlling the household appliance to work according to the control instruction when the received control instruction belongs to a target control instruction set.

[0015] To achieve the above objectives, a third aspect of the present invention provides a computer-readable storage medium storing a voice control program for a household appliance, which, when executed by a processor, implements the aforementioned voice control method for the household appliance.

[0016] To achieve the above objectives, a fourth aspect of the present invention provides a household appliance, including a memory, a processor, and a voice control program for the household appliance stored in the memory and executable on the processor.

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The following describes in detail, with reference to the accompanying drawings, the home appliances and their voice control methods, devices and storage media according to embodiments of the present invention.

[0026] In some embodiments, refer to Figure 1The voice control device for a household appliance according to this application embodiment includes a microprocessor 11, a human body sensor 12, other sensors 13, an Internet of Things module 14, a voice recognition processing module 15, a playback device 16, and a pickup device 17. The microprocessor 11 is connected to the human body sensor 12, other sensors 13, the Internet of Things module 14, and the voice recognition processing module 15. The voice recognition processing module 15 is connected to the playback device 16 and the pickup device 17.

[0027] Specifically, the human body sensor 12 can be a microwave radar sensor, used to detect human activity information within a preset range of the household appliance, such as activity, slight movement, stillness, and absence of people, and transmit this information to the microprocessor 11. The microwave signal emitted by the microwave radar sensor can penetrate opaque materials, thus not damaging the product's appearance and providing good privacy in special environments (such as bathrooms). Other sensors 13 can be determined according to the type of household appliance. For example, other sensors 13 installed on a bathroom heating device can be temperature sensors, humidity sensors, odor sensors, etc., used to acquire environmental information such as temperature and humidity in the bathroom and transmit it to the microprocessor 11. The Internet of Things (IoT) module 14 is used to connect the household appliance to the Internet. The sound pickup device 17 can be a microphone, used to capture sounds around the household appliance, such as command words and wake-up words in the environment, and convert them into electrical signals that are transmitted to the voice recognition processing module 15. The voice recognition processing module 15 processes the electrical signals acquired by the sound pickup device 17, identifies user control commands, and transmits the user control commands to the microprocessor 11. The microprocessor 11 controls the operation of home appliances according to user control commands. For example, when the user control command is to turn on the heating, it controls the bathroom heating device to turn on the heating function. When the human body sensor 12 detects human activity, the microprocessor 11 can also, based on environmental information and other information (such as time information, machine status information, user information, and control information), make a comprehensive judgment and then actively ask the user whether to activate a certain function or issue a prompt through the voice recognition processing module 15 and the playback device 16. After the user responds or a timeout period, it controls the home appliances to perform the corresponding operation. The playback device 16 is specifically a speaker, used to play sounds, such as prompts and messages issued by the home appliances.

[0028] It should be noted that the human body sensor 12 and other sensors 13 can be used as peripheral devices of the microprocessor 11 or as peripheral devices of the speech recognition processing module 15. In some embodiments of the present invention, the human body sensor 12 and other sensors 13 are used as examples of peripheral devices of the microprocessor 11, but this is not intended to limit the present invention.

[0029] For example, after detecting human activity information within a preset range of the home appliance, the human body sensor 12 transmits it to the microprocessor 11. The microprocessor 11 controls the home appliance to execute a command monitoring control strategy or a wake-up monitoring control strategy based on the human activity information. For instance, if human activity is detected, the home appliance (specifically, the voice recognition processing module 15) is controlled to execute the command monitoring control strategy; if no human activity is detected, the home appliance (specifically, the voice recognition processing module 15) is controlled to execute the wake-up monitoring control strategy. Furthermore, both voice recognition and active interactive control do not require a network connection, protecting privacy and ensuring reliable and stable local operation.

[0030] It should be noted that the microprocessor can also directly control the voice recognition processing module through other sensor information and user operation information, and control home appliances to execute command listening control strategies. For example, when the temperature sensor detects that the indoor temperature exceeds the preset value, it can directly control the air conditioner to execute command listening control strategies.

[0031] Figure 2 This is a flowchart of a voice control method for a household appliance according to some embodiments of the present invention. (Refer to...) Figure 2 The voice control method for household appliances in this application embodiment may include the following steps:

[0032] S110 detects human activity information within a preset range of household appliances.

[0033] Specifically, the household appliance is equipped with at least one human body sensing sensor, which may be a microwave radar sensor, to detect human activity information within a preset range of the household appliance and transmit it to a microprocessor. The human activity information may include states such as activity, slight movement, stillness, and absence of human presence.

[0034] It should be noted that the preset range can be determined according to the actual situation, such as within 2 meters of the household appliance, and there is no specific limitation. For example, when the household appliance is a bathroom heating device, the preset range can be determined according to the size of the bathroom.

[0035] S120, when human activity is determined to exist based on human activity information, controls home appliances to execute command monitoring control strategies.

[0036] Specifically, if the human body sensing sensor inside the home appliance detects human activity information as human movement or slight movement, it is determined that there is human activity within the preset range of the home appliance, indicating that the user may intend to control the home appliance by voice. Therefore, the control of the home appliance enters the command listening control process. At this time, the user can directly control the home appliance by saying the command word, saving the user the action of saying the wake-up word, which is simple to operate.

[0037] S130, when the received control command belongs to the target control command set, the control household appliance works according to the control command.

[0038] Specifically, after controlling the home appliance to execute the command monitoring control strategy, the system acquires sound within a preset range from the home appliance and transmits it to the speech recognition processing module. The module then identifies whether the sound within the preset range belongs to the target control command set. If it is determined that the sound within the preset range belongs to the target control command set, the corresponding control command is output to the microprocessor, which then controls the home appliance to operate according to the command. Otherwise, the command monitoring control process ends, and the home appliance enters the wake-up monitoring control process.

[0039] For example, let's take a bathroom heating device as an example. Assume the target control command set for the bathroom heating device includes commands such as "turn on the heating," "turn off the heating," "turn on the ventilation," and "turn off the ventilation." When human activity is detected in the bathroom, the bathroom heating device enters a command monitoring control process. If the user says "turn on the heating," the system picks up the sound and determines that the sound belongs to the target control command set for the bathroom heating device, then controls the device to turn on the heating. The user can then say "turn on the ventilation," and if the sound is determined to belong to the target control command set, the system controls the device to turn on the ventilation.

[0040] In this way, when human activity is detected within the preset range of a home appliance, continuous and complete control interaction can be performed based solely on the command word. This eliminates the need for the user to say the wake-up word, simplifies the process of voice control of home appliances, reduces the chance of erroneous operation, and ensures reliability.

[0041] In some embodiments, the above-described voice control method may further include: when it is determined, based on human activity information, that there is no human activity, controlling the home appliance to execute a wake-up monitoring control strategy.

[0042] Specifically, if the human body sensing sensor inside the home appliance detects no human activity, it is determined that there is no human activity within the preset range of the home appliance. However, the user may still be able to control the home appliance by voice. Therefore, the home appliance is controlled to enter the wake-up monitoring control process. If the user wants to control the home appliance, he / she needs to say the wake-up word first. When the wake-up word is the wake-up word preset by the user, the home appliance is controlled to enter the command monitoring control process.

[0043] In some embodiments, when a home appliance executes a wake-up monitoring control strategy, the above-described voice control method may further include: upon receiving a wake-up command and the wake-up command being a target wake-up word, controlling the home appliance to execute a command monitoring control strategy.

[0044] Specifically, after controlling the home appliance to execute the wake-up monitoring control strategy, the system acquires sound within a preset range from the home appliance and identifies whether the sound within that range is the target wake-up word. If the sound within the preset range is the target wake-up word, the system controls the home appliance to enter the command monitoring control process. Otherwise, the system does not control the home appliance to execute the command monitoring control strategy, but continues to control the home appliance to execute the wake-up monitoring control strategy.

[0045] For example, assuming the target wake-up word for a bathroom heater is "Xiao Mei Xiao Mei," when it's determined that there is no human activity in the bathroom, the heater enters a wake-up monitoring control process. After the user says "Xiao Mei Xiao Mei," the heater enters a command monitoring control program. When the user says "Turn on the heater," and it's determined that this sound belongs to the target control command set for the heater, the heater is turned on. If the user says "Clown Clown," and it's determined that this sound is not the target wake-up word for the heater, the appliance remains in the wake-up monitoring control process.

[0046] In this way, when the human body sensor determines that there is no human activity within the preset range of the appliance, the appliance will still execute the wake-up monitoring control strategy, which can reduce the probability of false triggering to a certain extent and enable the appliance to reliably standby or run.

[0047] In some embodiments, when the home appliance executes a command monitoring control strategy, the above-mentioned voice control method further includes: if no control command is received within a preset time, or if the control command does not belong to the target control command set, then controlling the home appliance to execute a wake-up monitoring control strategy.

[0048] Specifically, after controlling the home appliance to execute the command monitoring control strategy, if the pickup device does not receive any sound within a preset time, or if it is determined that the sound does not belong to the target control command set, the command monitoring control process ends and the home appliance enters the wake-up monitoring control process.

[0049] For example, suppose the target control command set for a bathroom heating device includes commands such as "turn on the heating," "turn off the heating," "turn on the ventilation," and "turn off the ventilation." When human activity is detected in the bathroom, the bathroom heating device is controlled to execute a command monitoring control strategy. If the user shouts "open the door" within a preset time, it is determined that this sound does not belong to the target control command set of the bathroom heating device, and the device is not controlled to operate; instead, a wake-up monitoring control strategy is executed. If the user does not make a sound within the preset time, the device is controlled to execute a wake-up monitoring control strategy.

[0050] In some embodiments, when the home appliance executes a command monitoring control strategy, the above-described voice control method further includes: acquiring environmental information of the home appliance, status information of the home appliance, and control commands; when one of the environmental information, status information of the home appliance, and control commands meets a corresponding preset condition, controlling the home appliance to issue an inquiry command; and controlling the home appliance according to the received response command.

[0051] Specifically, when a home appliance is executing a command monitoring control strategy, indicating the presence of human activity within a preset range, if environmental information obtained from other sensors (e.g., humidity information from a humidity sensor) and other information (e.g., the status information and control command information of the home appliance) meet the corresponding preset conditions, the home appliance can be controlled to actively issue an inquiry command. Based on the received response command, the home appliance can be controlled to actively interact with the user. Furthermore, the home appliance can also be controlled to proactively prompt the user about its current status or upcoming operation; in this case, the user does not need to interact, and the machine executes automatically.

[0052] As an example, other sensors on bathroom heating devices include humidity sensors and odor sensors. The device has multiple preset active interaction conditions. For instance, when the humidity sensor detects that the humidity has reached a preset value, the device proactively asks the user, "The humidity is high, would you like to turn on the ventilation?" The device determines whether to turn on ventilation based on the user's response. If the response is "Turn on ventilation," the device will turn on ventilation; otherwise, it will not. Similarly, when the odor sensor detects an odor, the device proactively asks the user, "An odor has been detected, would you like to turn on the air purification mode?" The device determines whether to turn on the air purification mode based on the user's response. If the response is "Turn on air purification mode," the device will turn on air purification mode; otherwise, it will not.

[0053] As another example, when a user controls the bathroom heating device to standby mode, the device proactively prompts, "The bathroom heating device will turn off immediately and will now perform a 30-second cooling operation." Once the user sets the heating temperature, and the device detects that the ambient temperature in the bathroom has reached that temperature, it proactively prompts, "The heating temperature has been reached; we are now activating the low-temperature heating mode for continuous heating."

[0054] Thus, when home appliances execute command monitoring control strategies, they can issue inquiry commands based on environmental information, their status information, or control instructions. This makes user scene control more accurate and intelligent, enhancing the user experience. Furthermore, the proactive voice prompts from home appliances help users better understand the machine's current status and actions, reducing learning costs. In addition, these inquiry commands and prompts do not require network transmission for recognition or behavior judgment; they only change the interaction method based on existing technology, without increasing costs.

[0055] It should be noted that wake-up-free continuous voice control, proactive interaction, and proactive prompts can also be enabled based on the operating status of home appliances. For example, when home appliances are operating, the human body sensor is not used to determine whether there is human activity within the preset range of the home appliance. An effective time period or time cycle can also be set. Within the effective time period or time cycle, the home appliance can be controlled to execute command monitoring control strategies, proactive interaction, and proactive prompts.

[0056] In some embodiments, controlling a home appliance according to a received response instruction includes: prohibiting the home appliance from issuing an inquiry instruction when the response instruction is to close the inquiry.

[0057] Specifically, a home appliance can have multiple ways to proactively interact with a user. The user can independently choose to turn each interaction on or off. For example, when the humidity in the bathroom is high, the bathroom heating device will proactively remind the user whether they need to turn on the fan function. If the user turns off the reminder, then when the humidity in the bathroom is detected to be high, the bathroom heating device will not issue a proactive reminder. In other words, the bathroom heating device will not proactively ask the user whether to turn on the fan function.

[0058] In this way, various proactive interaction methods and proactive voice prompts can be turned on or off according to the user's preset selection, which can avoid disturbing the user to a certain extent.

[0059] In some embodiments, the household appliance includes one of the following: lighting equipment, bathroom heating equipment, clothes rack, and fan light.

[0060] As a concrete example, refer to Figure 3 The voice control method for household appliances in this application embodiment may further include the following steps:

[0061] S201, acquire human body sensor information.

[0062] S202, determine whether there is human activity within the preset range of the household appliance. If yes, proceed to S205; otherwise, proceed to S203.

[0063] S203 controls home appliances to execute a wake-up monitoring control strategy, and the pickup device collects voice signals.

[0064] S204, determine whether the voice signal is the target wake-up word. If yes, proceed to S205; otherwise, continue with S204.

[0065] S205, control the home appliances to execute command monitoring control strategy, and the pickup device continues to collect voice signals.

[0066] S206, determine whether the voice signal belongs to the target control command set. If yes, execute S208; otherwise, execute S207.

[0067] S207, determine if the preset time has been exceeded. If yes, execute S203; otherwise, execute S206.

[0068] S208 controls household appliances to operate according to control instructions.

[0069] As another concrete example, refer to Figure 4 The voice control method for household appliances in this application embodiment may further include the following steps:

[0070] S301, Begin.

[0071] S302, acquire information from other sensors.

[0072] S303: Determine whether one of the following—environmental information, household appliance status information, or control command information—meets the corresponding preset conditions. If yes, execute S304; otherwise, execute S302.

[0073] S304, acquires human body sensor information.

[0074] S305, determine whether there is human activity within the preset range of the household appliance. If yes, proceed to S306; otherwise, proceed to S302.

[0075] S306: Control the home appliance to actively inquire whether to turn on a certain function or perform a certain action. If yes, execute S307; otherwise, execute S308.

[0076] S307, a household appliance turns on a certain function or performs a certain action.

[0077] S308, End.

[0078] In summary, when human activity is detected within a preset range of a home appliance, complete control interaction can be achieved solely based on command words, eliminating the need for users to speak wake words, simplifying voice control of home appliances, and reducing the chance of accidental operation. When the home appliance is executing a command monitoring control strategy, it can issue inquiry commands based on environmental information, its status information, or control instructions, making scene control more accurate and intelligent, enhancing the user experience. The proactive voice prompts from the home appliance help users better understand the machine's current status and actions, reducing learning costs. These inquiry commands and prompts do not require network transmission for recognition or behavior judgment; they only modify the interaction method based on existing technology, without increasing costs. Furthermore, multiple proactive interaction methods and proactive voice prompts can be enabled or disabled based on user presets, minimizing user disturbance to some extent.

[0079] Corresponding to the above embodiments, this application also proposes a voice control device for household appliances.

[0082] In some embodiments, the control module 520 is further configured to control the home appliance to execute a wake-up monitoring control strategy when it is determined, based on human activity information, that there is no human activity.

[0083] In some embodiments, the control module 520 is further configured to, when the home appliance executes a wake-up monitoring control strategy, control the home appliance to execute a command monitoring control strategy if a wake-up command is received and the wake-up command is a target wake-up word.

[0084] In some embodiments, the control module 520 is further configured to, when the home appliance executes a command monitoring control strategy, if no control command is received within a preset time, or if the control command does not belong to the target control command set, control the home appliance to execute a wake-up monitoring control strategy.

[0085] In some embodiments, the control module 520 is further configured to: acquire environmental information of the home appliance, status information of the home appliance, and control instructions when the home appliance executes a command monitoring control strategy; control the home appliance to issue an inquiry instruction when one of the environmental information, status information of the home appliance, and control instructions meets a corresponding preset condition; and control the home appliance according to the received response instruction.

[0086] In some embodiments, the control module 520 is further configured to control the household appliances according to the received response instructions, and to prohibit the household appliances from issuing inquiry instructions when the response instructions are to close the inquiry.
