[0048] In order to facilitate the understanding of the embodiments of the present application, the embodiments of the present application will be described more fully below with reference to the accompanying drawings. The preferred embodiments of the present application are shown in the drawings. However, the embodiments of the present application can be realized in many different forms and are not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the embodiments of the present application is more thorough and comprehensive.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments of the present application belong. The terminology used in the specification of the embodiments of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the embodiments of the present application.

[0050] It can be understood that the term "comprising / including" specifies the existence of the stated features, integers, steps, operations, components, parts or combinations thereof, but does not exclude the possibility of existence or addition of one or more other features, integers, steps, operations, components, parts or combinations thereof. The terms "first", "second" and the like can be used herein to describe various parameters, but these parameters are not limited by these terms. These terms are only used to distinguish the first parameter from another parameter. For example, without departing from the scope of the present application, the first state can be referred to as the second state, and the second state can be referred to as the first state.

[0051] As shown in Figure 1 The voice instruction acquisition method provided by the embodiments of the present application can be applied to a smart toilet, and the voice instruction acquisition method comprises steps 110 to 130.

[0052] Step 110, acquiring state information when the toilet is in operation.

[0053] The toilet's status information is used to characterize the current state of the toilet. Based on the status information, the current state of the toilet can be determined. The status includes, for example, the drying function being on or off.

[0054] Step 120: Adjust the sensitivity of acquiring control voice commands based on the status information.

[0055] Voice commands refer to the user's voice instructions to control the toilet to perform corresponding functions. Due to various noises, the voice module struggles to accurately identify these commands from a multitude of sounds. Specifically, when the voice module's sensitivity is too high, it is easily affected by subtle or distant, unrelated sounds, mistaking other voice commands for the user's control commands; conversely, when the sensitivity is too low, the user's control commands are easily masked by noise, making them impossible to identify. Understandably, the volume of sound produced by the toilet varies depending on its operating state, necessitating different sensitivity adjustments. Adjusting the sensitivity specifically based on these different operating conditions helps to more accurately identify the user's control commands.

[0056] Step 130: Acquire the voice signal with the adjusted sensitivity and obtain the control voice commands in the voice signal.

[0057] The voice signal refers to the sum of all sound signals, including user control voice commands, sounds generated by the toilet itself, and sounds from the surrounding environment. User control voice commands are used to control the toilet to operate according to the given instructions. For example, when the control voice command is "drying on," the toilet's drying device can be controlled to perform the drying operation. The sensitivity adjustment range of the voice module can be from level 1 to 10, with level 6 as the initial value. Higher levels indicate lower sensitivity. In this embodiment, the voice signal is acquired with a more appropriate adjusted sensitivity. This avoids situations where excessive sensitivity leads to interference from subtle or distant irrelevant sounds, while also avoiding situations where excessively low sensitivity causes the user's control voice commands to be masked by various noises. Therefore, the voice command acquisition method of this embodiment improves the accuracy of the voice module in acquiring control voice commands, enabling the toilet to acquire user control voice commands even in noisy environments.

[0058] like Figure 2 As shown, in one embodiment, the status information includes a first state and a second state, and the operating volume of the toilet in the first state is greater than the operating volume in the second state; adjusting the sensitivity of acquiring control voice commands according to the status information includes the following steps 210 to 220.

[0059] Step 210, when the toilet is switched from the second state to the first state, the sensitivity of obtaining the control voice instruction is adjusted to be higher.

[0060] In the embodiment, when the toilet is switched from the state with relatively small running volume to the state with relatively large running volume, it indicates that the noise volume generated by the toilet itself is increased. In order to avoid the control voice instruction of the user being covered by the noise as much as possible, the sensitivity of the voice module can be adjusted to be higher to collect the voice signal and obtain the control voice instruction of the user more accurately. For example, when the sensitivity of the voice module is adjustable from level 1 to level 10, and level 6 is the initial value, the larger the level value is, the lower the sensitivity is. When the toilet is switched from the state of flushing closed to the state of flushing open, the sensitivity can be adjusted from the initial value 6 to level 2.

[0061] Step 220, when the toilet is switched from the first state to the second state, the sensitivity of obtaining the control voice instruction is adjusted to be lower.

[0062] In the embodiment, when the toilet is switched from the state with relatively large running volume to the state with relatively small running volume, it indicates that the noise volume generated by the toilet itself is decreased. At this time, the possibility of the control voice instruction of the user being covered by the noise is relatively small, and it is unnecessary to have too high sensitivity. In order to avoid the other voice instructions being mistaken as the control voice instruction of the user due to the influence of the irrelevant sound from a small distance or a far distance, the sensitivity of the voice module can be adjusted to be lower to collect the voice signal and obtain the control voice instruction of the user more accurately. For example, when the toilet is switched from the state of flushing open to the state of flushing closed, the sensitivity can be adjusted from level 2 to the initial value 6.

[0063] It should be noted that, although Figure 2 Although the steps 210 and 220 are shown in sequence, in fact, the toilet cannot be switched from the first state to the second state and from the second state to the first state at the same time, so the voice module only needs to adjust the sensitivity according to the state information of the toilet, that is, only one of the steps 210 and 220 needs to be executed.

[0064] In one of the embodiments, the first state includes any one of the state of drying open, the state of cleaning open, the state of air pump open, and the state of flushing open, and the second state information includes any one of the state of drying closed, the state of cleaning closed, the state of air pump closed, and the state of flushing closed.

[0065] In the present embodiment, the first state can also be other states except the drying open state, the cleaning open state, the air pump open state and the flushing open state, and the second state can also be other states except the drying closed state, the cleaning closed state, the air pump closed state and the flushing closed state, which are not exhaustively listed in the present application. It should be understood that the closestool can be switched between the drying open state and the drying closed state, between the cleaning open state and the cleaning closed state, between the air pump open state and the air pump closed state, and between the flushing open state and the flushing closed state, and the voice module should adjust the sensitivity appropriately according to different state information to accurately obtain the control voice instruction of the user.

[0066] As shown in Figure 3 In one embodiment, the voice signal is collected at the adjusted sensitivity, and the control voice instruction in the voice signal is obtained, including the following steps 310 to 330.

[0067] Step 310, when the closestool is switched from the second state to the first state, the first voice signal is collected at the sensitivity which is adjusted to be higher, and the first voice signal includes the closestool noise signal, the environmental noise signal and the control voice instruction input by the user.

[0068] In the present embodiment, when the closestool is switched from the state with relatively small running volume to the state with relatively large running volume, the first voice signal obtained at this time includes the closestool noise signal generated by the operation of the closestool in addition to the environmental noise signal in the environment where the closestool is located and the control voice instruction input by the user.

[0069] Step 320, when the closestool is switched from the first state to the second state, the second voice signal is collected at the sensitivity which is adjusted to be lower, and the second voice signal includes the environmental noise signal and the control voice instruction input by the user.

[0070] In the present embodiment, when the closestool is switched from the state with relatively large running volume to the state with relatively small running volume, the sound generated by the operation of the closestool is small and can be ignored at this time, so the second voice signal obtained only includes the environmental noise signal in the environment where the closestool is located and the control voice instruction input by the user.

[0071] Similarly, although Figure 3 The steps 310 and 320 shown have a sequence, but in fact, the closestool cannot be switched from the first state to the second state and from the second state to the first state at the same time, so the voice module will only collect one of the first voice signal and the second voice signal in one collection, that is, only one of the steps 310 and 320 is executed and the corresponding voice signal is collected.

[0072] Step 330, obtaining the control voice instruction in the first voice signal or the second voice signal according to the target voice instruction.

[0073] In the embodiment, the target voice instruction can be one instruction, and the preset target voice instruction is determined according to the state information of the closestool. For example, when the closestool is in the drying opening state, the preset target voice instruction is determined as closing the drying. When the first voice signal or the second voice signal contains the same instruction as the target voice instruction, it is determined that the instruction is the control voice instruction and is obtained. The target voice instruction can also be multiple instructions, and the target voice instruction includes all control voice instructions that the user can give when the closestool is in operation. When the first voice signal or the second voice signal contains an instruction matching the instruction in the target voice instruction, it is determined that the instruction is the control voice instruction and is obtained. Through the voice instruction obtaining method in the embodiment, the control voice instruction in the voice signal can be more accurately and efficiently obtained.

[0074] As shown in the Figure 4 In one embodiment, the voice instruction obtaining method includes steps 410 to 450. That is, before step 430, obtaining the state information of the closestool in operation, the following steps 410 to 420 are further included. It should be noted that steps 430 to 450 of the embodiment can refer to the foregoing embodiments, and will not be described here.

[0075] Step 410, obtaining a noise reduction instruction.

[0076] Step 420, obtaining a comprehensive noise signal according to the noise reduction instruction, the comprehensive noise signal including an environmental noise signal and a closestool noise signal.

[0077] Specifically, when the closestool is in operation and in the first state, and the user does not give a control voice instruction, the comprehensive noise signal is obtained and stored according to the noise reduction instruction.

[0078] Step 430, obtaining the state information of the closestool in operation.

[0079] Step 440, adjusting the sensitivity of obtaining the control voice instruction according to the state information.

[0080] Step 450, collecting the voice signal with the adjusted sensitivity, and obtaining the control voice instruction in the voice signal according to the comprehensive noise signal.

[0081] In this embodiment, regardless of whether the voice signal is a first voice signal or a second voice signal, all sounds except the user's control voice commands can be filtered out from the voice signal based on the comprehensive noise signal, thus accurately acquiring the control voice commands while achieving noise reduction. It should be understood that the application of the voice command acquisition method in this embodiment requires first acquiring a comprehensive noise signal that can be filtered and denoised based on the noise reduction command.

[0082] like Figure 5 As shown, in one embodiment, obtaining control voice commands from a speech signal based on a composite noise signal includes steps 510 to 520.

[0083] Step 510: Obtain the sound frequency range of the integrated noise signal.

[0084] Step 520: Filter out the combined noise signal in the speech signal according to the sound frequency range to obtain control voice commands.

[0085] In this embodiment, regardless of whether the voice signal is the first voice signal or the second voice signal, the voice frequencies other than the user's control voice commands can be filtered out according to the sound frequency range of the comprehensive noise signal, so as to obtain the control voice commands more accurately.

[0086] like Figure 6 As shown, in one embodiment, the voice command acquisition method includes steps 601 to 610.

[0087] Step 601: Obtain the noise reduction command. Step 602: Obtain the composite noise signal according to the noise reduction command. The composite noise signal includes the ambient noise signal and the toilet noise signal. The above steps are for obtaining the composite noise signal.

[0088] Step 603: Acquire the toilet's operating status information, including a first state and a second state. The operating volume of the toilet in the first state is greater than that in the second state. The first state includes any one of the following: drying on, washing on, air pump on, and flushing on. The second state includes any one of the following: drying off, washing off, air pump off, and flushing off. Step 604: When the toilet switches from the second state to the first state, increase the sensitivity for acquiring control voice commands. Step 605: Acquire a first voice signal with the increased sensitivity. The first voice signal includes toilet noise, ambient noise, and user-input control voice commands. Step 606: When the toilet switches from the first state to the second state, decrease the sensitivity for acquiring control voice commands. Step 607: Acquire a second voice signal with the decreased sensitivity. The second voice signal includes ambient noise and user-input control voice commands. It should be noted that... Figure 6As shown, steps 604 to 605 and steps 606 to 607 correspond to two situations that cannot occur at the same time, and the voice module can select one of them according to the state information of the operation of the toilet. The above steps are steps of collecting voice signals.

[0089] Further, step 608, obtain the sound frequency range of the comprehensive noise signal, step 609, filter the comprehensive noise signal in the first voice signal or the second voice signal according to the sound frequency range to obtain the control voice instruction. Or step 610, obtain the control voice instruction in the first voice signal or the second voice signal according to the target voice instruction. It should be noted that, although Figure 6 Steps 601 to 610 are shown, and the order between steps is shown, but in fact, steps 608 to 609 and step 610 only need to be executed one of them, that is, when steps 601 to 602 are executed, only steps 608 to 609 need to be executed without executing step 610; when steps 601 to 602 are not executed, only 610 needs to be executed without executing steps 608 to 609. The above steps are steps of obtaining the control voice instruction.

[0090] In this embodiment, the voice module obtains the state information of the operation of the toilet, adjusts the sensitivity of obtaining the control voice instruction of the user according to different state information, and then collects the voice signal with the adjusted appropriate sensitivity and more accurately obtains the control voice instruction in the voice signal. Among them, the voice module can obtain the control voice instruction in the voice signal according to the target voice instruction, or obtain the noise reduction instruction before obtaining the state information of the operation of the toilet, and obtain the comprehensive noise signal according to the noise reduction instruction, and then perform noise reduction processing on the voice signal through the comprehensive noise signal to obtain the control voice instruction. No matter which of the above two ways is used, the accuracy of the voice module in obtaining the control voice instruction can be improved, so that the toilet can obtain the control voice instruction of the user even in a noisy environment.

[0091] As Figure 7 As shown, the present application also provides a toilet control method, which comprises steps 710 to 740.

[0092] Step 710, obtain the state information of the operation of the toilet.

[0093] Step 720, adjust the sensitivity of obtaining the control voice instruction according to the state information.

[0094] Step 730, collect the voice signal with the adjusted sensitivity, and obtain the control voice instruction in the voice signal.

[0095] At step 740, the closestool is controlled to work according to the control voice instruction.

[0096] The steps 710 to 730 are described above and will not be repeated here.

[0097] The step 740 can be performed by a control module in the closestool. The control module can control the closestool to work according to the control voice instruction. For example, when the control voice instruction is an oven opening instruction, the control module can control the closestool to perform the drying operation.

[0098] In this embodiment, after the control voice instruction of the user is accurately obtained by the voice instruction method, the closestool is controlled to work according to the control voice instruction, so that the closestool can accurately and effectively execute the control voice instruction of the user to accurately meet the needs of the user.

[0099] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are displayed in sequence according to the arrows, these steps are not necessarily executed in sequence according to the arrows. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least some of the steps in the flowcharts involved in the above-described embodiments can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least some of the other steps or the steps or stages in the other steps.
