Description

Technical Field

[0001] This invention relates to the technical field of intelligent voice control methods for smart home appliances, and in particular to a voice interaction control method for smart home appliances, a smart home appliance implementing the voice interaction control method, and a computer-readable storage medium. Background Technology

[0002] With the rapid development of smart home technology, voice interaction has gradually become a core selling point of smart home appliances, especially in products such as dehumidifiers, air purifiers, air conditioners, electric fans, televisions, and speakers. Taking dehumidifiers as an example, their voice systems support proactive announcements (such as device status, maintenance reminders, and fault alerts) and wake-up responses (e.g., when a user says "What is the current humidity?", the voice response is "The current humidity is 50%"; or when a user says "Turn the humidity down one level", the voice response is "It has been lowered to level 3 for you"; etc.), thus significantly improving the convenience of smart operation for users.

[0003] In real-world usage scenarios, the voice interaction function of smart home appliances cannot distinguish the user's actual sleep state. This can lead to the system triggering proactive voice broadcasts during daytime naps or nighttime sleep, or outputting high-volume responses after being mistakenly awakened by environmental noise. Such sudden high-volume voice interference seriously disrupts the user's rest quality and affects the user experience.

[0004] To avoid disturbing users' rest with the voice interaction functions of smart home devices, existing smart home systems typically switch to a silent / do-not-disturb mode during preset nighttime periods, such as 11:00 PM to 6:00 AM. However, users may not be resting or sleeping during these preset nighttime periods. Therefore, existing smart home systems cannot detect the user's actual rest or sleep status, especially when the user is sleeping outside of these preset nighttime periods. Sudden high-volume voice interruptions can still disrupt the user's sleep, causing the silent / do-not-disturb mode to fail during the user's actual sleep time or the voice interaction function to be accidentally turned off during non-sleep times. Furthermore, after the voice interaction function of existing smart home systems switches to silent / do-not-disturb mode, the device's operational status is left blank, preventing users from knowing the device's working status during the silent / do-not-disturb mode, especially malfunctions or abnormalities. This hinders timely handling of device abnormalities and ultimately affects the device's performance. Summary of the Invention

[0005] To achieve the first objective of this invention, the present invention provides a voice interaction control method for smart home appliances. This method can dynamically and accurately sense the user's real-time status to dynamically adapt to different strategies of the voice interaction function of the smart home appliance. This precisely prevents the voice interaction function of the smart home appliance from interfering with the user's sleep and rest, and accurately realizes intelligent interaction of the voice interaction function during non-sleep and rest periods. This improves the accuracy and stability of the voice interaction control of the smart home appliance, thereby enhancing the user experience. Furthermore, it can record or provide feedback on the working status of the smart home appliance at all times, so that the user can promptly handle abnormal conditions of the smart home appliance, thereby ensuring the operating performance of the smart home appliance.

[0015] A further approach is to confirm that the target user's real-time state is in a sleep or rest state under the following conditions: the duration of the target user's inactivity exceeds a first time threshold.

[0016] A further solution is to confirm that the target user's real-time state is a sleep or rest state, which also includes the condition that the ambient noise in the environment where the smart home appliance is located is less than or equal to a preset noise level for a second time period.

[0017] A further solution is to confirm that the target user's real-time state is a sleep or rest state, which also includes the condition that the ambient light intensity of the environment where the smart home appliance is located is less than or equal to the preset light intensity for a third consecutive time threshold.

[0018] A further proposed solution is to set the illuminance to 100 lux when the current time is identified as being within a preset daytime period; to set the illuminance to 5 lux when the current time is identified as being within a preset nighttime period; and / or to set the noise level to 20 dB.

[0019] To achieve the second objective of this invention, this invention provides a smart home appliance, including a voice interaction module and a circuit board electrically connected to the voice interaction module.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0035] Example of a voice interaction control method for smart home appliances: See Figure 1The smart home appliance of this embodiment includes a voice interaction module 10 and a circuit board 20 electrically connected to the voice interaction module 10. It also includes a light sensor 30, a noise sensor 40, an infrared sensor 50, an indicator light 60, a communication module 70, and a time sensing module 80, all electrically connected to the circuit board 20. The light sensor 30 is used to detect the ambient light level of the environment in which the smart home appliance is located in real time. The noise sensor 40 is used to detect the ambient noise in the environment in which the smart home appliance is located in real time. The infrared sensor 50 is used to detect the real-time status of the target user in the environment in which the smart home appliance is located. The indicator light 60 is used to flash a red light to indicate a warning. The communication module 70 is used to wirelessly communicate between the smart home appliance and the mobile APP. The time sensing module 80 is used to detect the current time (Beijing time, China) in real time. In this embodiment, the voice interaction module 10 of the smart home appliance includes a microphone, a speaker, and a voice processing and generation module. The microphone receives and processes the user's voice and transmits it to the voice processing and generation module. The voice processing and generation module processes the acquired voice information and generates a preset response voice. The preset response voice is broadcast through the speaker. Taking a dehumidifier as an example, if the user says "What is the current humidity?", the voice response is "The current humidity is 50%"; if the user says "Turn the humidity down one level", the voice response is "It has been lowered to level 3 for you", etc. The voice processing and generation module can also receive the real-time working status of the smart home appliance transmitted by the circuit board 20 and process it to generate a preset broadcast voice. The preset broadcast voice is actively broadcast through the speaker, such as device status, maintenance prompts, fault reminders, etc.

[0036] See Figures 2 to 6 The specific steps of the smart home appliance voice interaction control method in this embodiment are as follows.

[0037] Step S11 is executed to control the smart home appliance to start operating in a preset operating mode. Specifically, the user can control the smart home appliance to start operating by sending a start signal to it via remote control, or by touching the touchscreen on the smart home appliance. In this embodiment, the smart home appliance is started by the user through voice interaction, thereby improving the convenience of smart operation.

[0038] Next, step S12 is executed, where the real-time status of the target user in the environment where the smart home appliance is located is identified every preset time interval. Specifically, in this embodiment, the preset time interval is 5 minutes.

[0039] Subsequently, step S13 is executed. If it is determined that the real-time status of the target user is active for a consecutive preset number of times, then step S14 is executed to control the smart home appliance to execute the ordinary voice interaction strategy.

[0040] Specifically, the general voice interaction strategy in this embodiment includes: responding to a preset active broadcast function at a first preset volume; responding to a preset important wake-up response at a first preset volume; and responding to a preset secondary wake-up response at a first preset volume. Further, the first preset volume in this embodiment is 60dB.

[0041] In this embodiment, the preset number of times is at least two, so that the smart home appliance is controlled to execute the normal voice interaction strategy only after it is determined that the real-time status of the target user is active for at least two consecutive times. This is to avoid the risk of misjudgment in the smart home appliance voice interaction control method of this embodiment, so as to enable the user to accurately realize the intelligent interaction of the voice interaction function during non-sleep rest periods. The smart home appliance responds to the preset active broadcast function, preset important wake-up response and preset secondary wake-up response with the first preset volume, so as to improve the accuracy and stability of the smart home appliance voice interaction control.

[0042] After executing step S12, if step S15 is executed and the target user's real-time state is identified as a sleep or rest state, then step S16 is executed to control the smart home appliance to execute a downgraded voice interaction strategy.

[0043] Specifically, the downgraded voice interaction strategy in this embodiment includes: disabling the preset active broadcast function and sending the information of the preset active broadcast function to the mobile APP and / or controlling the indicator light 60 of the smart home appliance to flash; or, responding to the preset active broadcast function at a second preset volume and sending the information of the preset active broadcast function to the mobile APP; furthermore, the downgraded voice interaction strategy in this embodiment also includes: responding to the preset important wake-up response at a third preset volume; and furthermore, the downgraded voice interaction strategy in this embodiment also includes: controlling the indicator light 60 of the smart home appliance to flash in response to the preset secondary wake-up response.

[0044] In this embodiment, a pre-set active broadcast function is used to broadcast important information such as device status, maintenance prompts, and fault reminders in real time. Thus, when the smart home appliance executes the downgraded voice interaction strategy, it will send the information from the pre-set active broadcast function to the mobile APP to record and provide feedback on the working status of the smart home appliance at all times, so that users can deal with abnormal situations of the smart home appliance in a timely manner, thereby ensuring the operating performance of the smart home appliance.

[0045] Furthermore, in this embodiment, the second preset volume is lower than the first preset volume, and the third preset volume is lower than the first preset volume. Preferably, in this embodiment, the second preset volume is less than or equal to 30dB (similar to a whisper), and the third preset volume is less than or equal to 30dB, to ensure that the second and third preset volumes are within the sleep tolerance range, thereby preventing the voice interaction function of smart home appliances from interfering with the user's sleep and rest, and improving the user experience.

[0046] Furthermore, the conditions for identifying the target user's real-time state as a sleep / rest state in step S15 of this embodiment include: the duration of the target user's inactivity exceeding a first time threshold; simultaneously, the conditions for identifying the target user's real-time state as a sleep / rest state in step S15 of this embodiment also include: the ambient noise in the environment where the smart home appliance is located continuously for a second time threshold less than or equal to a preset noise level; simultaneously, the conditions for identifying the target user's real-time state as a sleep / rest state in step S15 of this embodiment also include: the ambient light intensity in the environment where the smart home appliance is located continuously for a third time threshold less than or equal to a preset light intensity.

[0047] Specifically, in this embodiment, the first time threshold is 30 minutes, the second time threshold is 30 minutes, the third time threshold is 30 minutes, the preset noise level is 20 dB, and when the current time is identified as being within a preset daytime period, the preset illuminance is 100 lux (a typical daytime sleeping environment with curtains drawn); when the current time is identified as being within a preset nighttime period, the preset illuminance is 5 lux (a typical nighttime dark environment).

[0048] In this embodiment, step S15, identifying the target user's real-time state as a sleep / rest state, requires the following three conditions to be met simultaneously: (i) If the duration of no activity by the target user exceeds the first time threshold, that is, if the infrared sensor 50 detects that the duration of no activity by the target user in the environment where the smart home appliance is located exceeds 30 minutes, then it is determined that the target user has no activity for more than 30 minutes. (ii) The ambient noise in the environment where the smart home appliance is located is less than or equal to the preset noise for a second time. That is, the noise sensor 40 detects that the ambient noise in the environment where the smart home appliance is located is less than or equal to 20dB for 30 minutes, indicating that the environment where the smart home appliance is located has been in a "low noise environment" state for 30 minutes. (iii) The ambient light intensity of the environment where the smart home appliance is located is less than or equal to the preset light intensity for a third time. That is, the light sensor 30 detects that the ambient light intensity of the environment where the smart home appliance is located is less than or equal to 5 lux (at which time the current time is within the preset night period) / 100 lux (at which time the current time is within the preset day period) for 30 minutes. This indicates that the environment where the smart home appliance is located has been in a "dark environment" state for 30 minutes.

[0049] Therefore, in this embodiment, step S15, identifying the target user's real-time state as a sleep state, requires simultaneously meeting three conditions: "no user activity," "low noise environment," and "dark environment." This ensures accurate and clear determination of the target user's real-time state as a sleep state, avoids misjudgment, and precisely prevents the voice interaction function of smart home appliances from interfering with the user's sleep.

[0050] When the current time of operation of the smart home appliance is within a preset daytime period, i.e., step S17 identifies that the current time is within the preset daytime period, then step S161 is executed. The downgraded voice interaction strategy includes a first important interaction operation and a first required interaction operation. The first important interaction operation includes: responding to the preset active broadcast function at a second preset volume and sending the information of the preset active broadcast function to the mobile APP. The first required interaction operation includes: turning off the preset active broadcast function and sending the information of the preset active broadcast function to the mobile APP.

[0051] Therefore, when smart home appliances are operating during preset daytime hours, the downgraded voice interaction strategy responds to the preset active broadcast function at 30dB when performing the first important interactive operation. This involves quietly broadcasting important preset active broadcast functions (such as equipment malfunctions, abnormalities, etc.). Since users are usually in a light sleep or resting state with their eyes closed during the day, they may be awake at this time and can deal with equipment malfunctions and abnormalities immediately, thus ensuring the operating performance of smart home appliances. Moreover, all relevant information is recorded or fed back to the mobile APP at all times so that users can deal with abnormalities of smart home appliances in a timely manner after waking up, thereby ensuring the operating performance of smart home appliances.

[0052] When the current time of operation of the smart home appliance falls within a preset nighttime period, i.e., step S18 identifies that the current time is within the preset nighttime period, then step S162 is executed. The downgraded voice interaction strategy includes a second important interaction operation and a second required interaction operation. The second important interaction operation includes: turning off the preset active broadcast function, sending the information of the preset active broadcast function to the mobile APP, and controlling the indicator light 60 of the smart home appliance to flash. The second required interaction operation includes: turning off the preset active broadcast function, and sending the information of the preset active broadcast function to the mobile APP.

[0053] Therefore, when smart home appliances are operating during the preset nighttime hours, the second important interaction operation of the downgraded voice interaction strategy is performed. By turning off the preset active broadcast function and sending the information of the preset active broadcast function to the mobile APP, and controlling the indicator light of the smart home appliance to flash 60 degrees, users can know that the device has a fault or abnormal status when they get up to use the toilet or get a drink in the middle of the night. This allows for immediate handling of device faults and abnormal situations, ensuring the operating performance of the smart home appliance. All relevant information is recorded or fed back to the mobile APP at all times, so that users can deal with the abnormal situation of the smart home appliance in a timely manner after waking up, thereby ensuring the operating performance of the smart home appliance.

[0054] Therefore, the smart home appliance voice interaction control method in this embodiment can dynamically and accurately perceive the user's real-time status to dynamically adapt to different strategies of the smart home appliance's voice interaction function, so as to accurately prevent the smart home appliance's voice interaction function from interfering with the user's sleep and rest, and accurately realize the intelligent interaction of the voice interaction function during non-sleep and rest periods, thereby improving the accuracy and stability of the smart home appliance's voice interaction control, thereby improving the user experience. It can also record or provide feedback on the working status of the smart home appliance at all times, so that the user can deal with the abnormal situation of the smart home appliance in a timely manner, thereby ensuring the operating performance of the smart home appliance.

[0055] Taking a smart dehumidifier as an example, the specific steps of the voice interaction control method are as follows.

[0056] I. Equipment System Initialization and Scene Setting (1) Device status: The smart dehumidifier is equipped with the smart home appliance voice interaction control method of this embodiment, and has been connected to Wi-Fi for push to mobile APP. The relevant voice logic of the voice interaction module 10 runs offline.

[0057] (2) User settings: If the user customizes the “preset nighttime period” as 22:00-07:00 in the device or mobile APP, then the “preset daytime period” will be 07:01-21:59.

[0058] (3) Initial state upon power-on: The default is to execute the normal voice interaction strategy, responding with a volume of 60dB to the preset active broadcast function, preset important wake-up response and preset secondary wake-up response.

[0059] II. Demonstration of Operating Scenarios Scenario 1: Daytime nap mode (not during the preset nighttime period, but the user is in a sleep or resting state) Background: At 2:00 PM, the user closed the bedroom curtains and lay down to rest for a nap.

[0060] 1. Time Awareness: The time awareness module 80 reads the current time as 14:00 and determines that it is within the preset daytime period.

[0061] 2. Status detection (sampled once every 5 minutes) (1) Light: The light sensor 30 detected that the ambient light intensity was less than or equal to 100 lux for 30 minutes, indicating that the environment where the smart dehumidifier is located has been in a "dark environment" state for 30 minutes (the user draws the curtains).

[0062] (2) Noise: The noise sensor 40 detected that the ambient noise was less than or equal to 20dB for 30 minutes, indicating that the environment where the smart dehumidifier is located has been in a "low noise environment" state for 30 minutes.

[0063] (3) Activity: If the light sensor 30 detects that the target user has no activity for 30 minutes, it is determined that the target user has no activity for 30 minutes.

[0064] 3. Real-time status assessment of target users Since the time-aware module 80 reads the current time as 14:00 and the status detection meets the three conditions of "no user activity", "low noise environment" and "dark environment", it determines that the target user's real-time status is a daytime sleep and rest state.

[0065] 4. Implement a downgraded voice interaction strategy (1) Active broadcast function: If the dehumidifier detects a safety event such as the water tank is about to overflow or the filter needs to be cleaned, it will perform the first important interactive operation, broadcasting "humidity over-limit alarm" or "filter blockage" or "dehumidifier malfunction" in a low 30dB voice, and send the relevant information of the preset active broadcast function to the mobile APP. If the user is awake at this time, he / she can deal with the equipment malfunction or abnormal situation as soon as possible, thereby ensuring the dehumidifier's operating performance. If the dehumidifier detects secondary broadcast information such as the preset timed task has been completed, it will perform the second important interactive operation, turn off the preset active broadcast function, and send the information of the preset active broadcast function to the mobile APP.

[0066] (2) Important wake-up response: If the user says "What is the current humidity?" or other system-recognized wake-up words, the system will respond with a 30dB soft voice to the preset important wake-up response, that is, to answer "The current humidity is 50%" or "The current humidity is 50%" in a 30dB soft voice.

[0067] (3) Secondary wake-up response: If the user says "lower the humidity by one level", the system will not reply "lowered to level 3 for you", but will control the indicator light of the smart home appliance to flash 60 to indicate that the operation was successful, without making a sound.

[0068] Scenario 2: Nighttime Deep Sleep Mode (Preset nighttime period, user is in a sleep and resting state) Background: At 11:30 PM, the user has entered a deep sleep.

[0069] 1. Time perception: The time perception module 80 reads the current time as 23:30 and determines that it is within the preset nighttime period.

[0070] 2. Status detection (sampled once every 5 minutes) (1) Light: The light sensor 30 detected that the ambient light intensity was less than or equal to 5 lux for 30 minutes, indicating that the environment where the smart dehumidifier is located has been in a "dark environment" state for 30 minutes (lights off at night).

[0071] (2) Noise: The noise sensor 40 detected that the ambient noise was less than or equal to 20dB for 30 minutes, indicating that the environment where the smart dehumidifier is located has been in a "low noise environment" state for 30 minutes.

[0072] (3) Activity: If the light sensor 30 detects that the target user has no activity for 30 minutes, it is determined that the target user has no activity for 30 minutes.

[0073] 3. Real-time status assessment of target users Since the time-aware module 80 reads the current time as 23:30 and the status detection meets the three conditions of "no user activity", "low noise environment" and "dark environment", it determines that the target user's real-time status is a sleep and rest state at night.

[0074] 4. Implement a downgraded voice interaction strategy (1) Active broadcast function: If the dehumidifier detects a safety event such as the water tank is about to overflow or the filter needs to be cleaned, it will perform the second important interactive operation, turn off the preset active broadcast function, send the information of the preset active broadcast function to the mobile APP, and control the indicator light 60 of the smart home appliance to flash, so that when you get up to go to the toilet or get a drink of water in the middle of the night, you can know that the equipment has a fault or abnormal status, so that you can deal with the equipment fault or abnormal status as soon as possible to ensure the dehumidifier's operating performance; If the dehumidifier detects a secondary broadcast information such as the preset timed task has been completed, it will perform the second important interactive operation, turn off the preset active broadcast function, and send the information of the preset active broadcast function to the mobile APP.

[0075] (2) Important wake-up response: If the user says "What is the current humidity?" or other system-recognized wake-up words, the system will respond with a 30dB soft voice to the preset important wake-up response, that is, to answer "The current humidity is 50%" or "The current humidity is 50%" in a 30dB soft voice.

[0076] (3) Secondary wake-up response: If the user says "lower the humidity by one level", the system will not reply "lowered to level 3 for you", but will control the indicator light of the smart home appliance to flash 60 to indicate that the operation was successful, without making a sound.

[0077] Scenario 3: Demonstration of anti-false alarm mechanism (brief nighttime activity / false wake-up) Background: At 2:00 AM, the user got up to go to the bathroom and turned on the light. On the way, they passed by the dehumidifier or heard a slight unusual noise in the environment.

[0078] 1. Exception Trigger When a user gets up at night to turn on the light, the light sensor 30 detects that the ambient light level instantly brightens (greater than 5 lux). Alternatively, when a user passes by the dehumidifier, the footsteps cause the noise sensor 40 to detect that the ambient noise briefly rises to greater than 20 dB.

[0079] 2. Continuously verify and adapt to different voice interaction strategies (sample once every 5 minutes). First sampling (02:05): "Light / Noise" was detected, and the target user was determined to be "Active".

[0080] If, during the second sampling (02:10), the user returns to bed and the environment becomes dark and quiet again, and the target user is determined to be "sleeping," then the dehumidifier's voice interaction control method will continue to execute the downgraded voice interaction strategy.

[0081] If the second sampling (02:10) detects "light / noise", and determines that the target user is "active", then if the target user is identified as "active" twice in a row, then the voice interaction control method of the dehumidifier will be switched to execute the normal voice interaction strategy, and the preset active broadcast function, preset important wake-up response and preset secondary wake-up response will be responded to with a volume of 60dB.

[0082] Scenario 4: Waking up naturally and working during the day (unlocking the downgrade) Background: At 7:10 AM, the user wakes up and opens the curtains.

[0083] 1. Time perception: The time perception module 80 reads the current time as 07:10 and determines that it is within the preset daytime period.

[0084] 2. Status detection and continuous verification (sampling once every 5 minutes) When a user opens the curtains, the light sensor 30 detects that the ambient light level instantly brightens (greater than 100 lux), the user gets out of bed and walks around, and the noise sensor 40 detects that the ambient noise briefly rises to greater than 20 dB, then it is confirmed that the target user is active.

[0085] When the target user is identified as "active" twice in a row, it is accurately determined that the target user is "active" during the day. The voice interaction control method of the dehumidifier is then switched to execute the normal voice interaction strategy, responding with a preset active broadcast function, preset important wake-up response and preset secondary wake-up response at a volume of 60dB. For example, it actively broadcasts at a volume of 60dB, such as "The humidity is suitable today, it is recommended to turn on the fresh air mode", "Humidity exceeds the standard alarm", "Dehumidifier malfunction", "Filter blockage" etc.
