Description

Technical Field

[0001] This application relates to the field of voice control technology, specifically to a voice control method and device. Background Technology

[0002] In a distributed multi-device voice control system, if multiple devices use the same wake-up mechanism, a voice control strategy of waking up or responding to the nearest device is generally adopted to avoid confusion caused by multiple devices responding at the same time.

[0003] However, when multiple devices are placed very close together, such as stacked or side-by-side, the existing proximity wake-up mechanism can still cause unstable responses. For example, when two devices are stacked one on top of the other, the two devices often respond randomly when the user performs voice control, causing voice control confusion and affecting the user experience.

[0004] Therefore, existing technologies suffer from the technical problem that the proximity-based wake-up mechanism for voice control fails when multiple devices are located too close together. Summary of the Invention

[0005] This application provides a voice control method and apparatus, which solves the technical problem that the proximity wake-up mechanism of voice control fails when multiple devices are located too close together in the prior art.

[0026] Based on the result of the second request, the group master control device that has obtained the permission is determined, so that the group master control device responds to the voice command and sends the master control request information to the network.

[0027] In one possible design, the preset distance requirement includes: the distance between each device is less than or equal to a preset distance threshold.

[0028] Secondly, this application provides a voice control method applied to a network central control device, comprising:

[0052] or,

[0053] Send users a purchase link for the target device, which is a device capable of performing the target task.

[0054] In one possible design, when the first device group includes multiple voice control devices, the sending module is also used to respond to the received voice command by sending an intra-group master control request to the network or the first device group. The intra-group master control request is used to request permission to respond to voice commands within the first device group.

[0055] The receiving module is also used to receive the second request result from the network feedback;

[0085] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort, including but not limited to combinations of multiple embodiments, are within the scope of protection of this application.

[0086] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0087] Currently, distributed multi-device voice control systems use a proximity wake-up mechanism to prevent multiple devices from responding to a single call. However, this also presents a problem: when multiple devices are placed very close together, such as stacked or side by side, the proximity wake-up mechanism often results in the device responding frequently changing, which can cause great inconvenience to users.

[0088] Figures 1a-1b This is a schematic diagram illustrating a scenario where a voice control device is installed at extremely close range, as provided in this application. Figure 1a The scene depicts a washing machine and a dryer placed side by side. Figure 1b This scenario involves a washing machine and a dryer stacked side-by-side. In this case, existing technologies typically address the issue of the response object randomly jumping between the two devices, a problem that arises with proximity-based response mechanisms, by improving the recognition accuracy of the audio acquisition device.

[0089] Unlike the aforementioned conventional techniques, this application addresses the technical problem of the failure of the proximity-based wake-up mechanism for voice control when multiple devices are too concentrated in one location. The inventive concept of this application is:

[0090] To address the inaccuracy issues arising from proximity-based response mechanisms in voice control at extremely close range, devices placed within very short distances (e.g., less than 1 meter apart) were grouped. Grouping was based on functional compatibility or proximity in installation location. Each device group shares at least one voice module. Multiple device groups may exist in the same scenario. Groups are equal until a user issues a voice command. Once a command is issued, groups compete for control. The group with the winning voice module becomes the master control group, and the remaining groups become slave control groups. Only the master control group has the authority to respond to user voice commands. The master control group's voice module retrieves the function list of all devices in each group and analyzes whether the voice command can be completed by devices within the master control group. If not, control is transferred to a capable slave control group, or the master control group directly controls the slave devices to complete the task specified in the voice command.

[0091] Similarly, if a group contains multiple voice modules, the mechanism for determining the master voice module within the group is also based on a competitive application process. This ensures that the voice control function of the entire group is not affected by a particular voice module being in a working, dormant, or damaged state.

[0092] The voice control method provided in this application will be described in detail below with reference to the accompanying drawings.

[0093] The specific steps of the voice control method provided in this application will be described in detail below with reference to several embodiments.

[0094] Figure 2 This is a flowchart illustrating a voice control method provided in an embodiment of this application. Figure 2 As shown, the specific steps of this voice control method include:

[0095] S201, Receive user's voice commands.

[0096] In this embodiment, a number of electronic devices are installed in a certain space, and some devices are installed very close together, such as placed side by side or stacked one on top of the other. Similar spatial scenarios include: kitchens, bathrooms, balconies, vehicles, factory production areas, product sales and display areas, etc.

[0097] Once these electronic devices are connected to the same network, such as a local area network or the Internet of Things, the central control server or central control equipment can automatically group them according to their functions or installation locations to identify at least one device group.

[0098] In one possible design, users can access the network via a voice control management application on their mobile devices and then customize the groups of individual devices to identify at least one device group.

[0099] In this step, each device group has at least one audio acquisition array, such as a microphone array group, in its voice control device. Each audio acquisition array includes at least two independent acquisition modules, such as two independent microphones.

[0100] When a user speaks a voice command from any location, the corresponding sound wave signal is transmitted to the user's environment and received by the audio acquisition array installed on at least one voice control device in each device group.

[0101] S202. Send master control request information to the network where the device group is located.

[0102] In this step, the network includes multiple device groups, and the master control request information is used to request the first device group to obtain the permission to respond to voice commands.

[0103] Specifically, at least one voice control device in each device group sends a master control request to the central server or central control device in the network to obtain the permission to respond to user voice commands.

[0104] It should be noted that the implementation methods of the central server or central control equipment include at least one of the following: cloud server, local server, independent central control unit, and a pre-set device to be controlled.

[0105] S203, Receive master control request information sent by each device group.

[0106] In this step, the central control device or central server receives the master control request information sent by each device group through the gateway interface.

[0107] S204. Based on the master control request information and the preset response allocation principle, determine the first device group to be assigned the response permission.

[0108] In this step, the preset response allocation principles include: the principle of permission contention, which means that the response permission is allocated to the device group that made the request first, i.e., the first device group.

[0109] Correspondingly, in one possible implementation, the master control request information includes the request sending time, which facilitates the central control device to identify the earliest request based on the request sending time.

[0110] In another possible design, the central control device allocates resources based on the first master control request received, rather than based on the time the request was sent.

[0111] In one possible design, the preset response allocation principle includes: allocating responses based on the response level of each device group, with the device group having the highest response level receiving the response permission.

[0112] It should be noted that in this design, the response level of the device group needs to be defined in advance when the device group is created.

[0113] It is understandable that if multiple device groups have the same response level, the two allocation methods mentioned above can be combined. That is, the device group that requests the request first among those with the same response level will obtain the response permission, or the device group corresponding to the master control request that is first received by the central control device will obtain the response permission.

[0114] S205. Feedback the allocation results of response permissions to the first device group or all device groups.

[0115] S206. Receive the first request result from the network.

[0116] For steps S205 to S206, specifically, in one possible implementation, the central control device only feeds back the first request result of obtaining response permission to the first device group. If other device groups do not receive the first request result within a preset time, it is confirmed that they have not obtained response permission.

[0117] In another possible implementation, the central control device feeds back the first request result to all device groups through the network bus. The first request result includes the first identity information of the first device group that has obtained the response permission. Each device group reads the first request result and matches its own identity information with the first identity information to determine whether it has obtained the response permission.

[0118] S207. If the first device group obtains response permission based on the result of the first request, then the first device group controls at least one target device to execute the target task indicated by the voice command.

[0119] In this step, after the first device group confirms that it has obtained the response permission, the semantic parsing model is used to perform semantic parsing on the user's voice commands in order to determine the target device and control commands.

[0120] For example, the content of voice commands is recognized and converted into corresponding text, and then semantic recognition is performed on the text to extract the target control device.

[0121] For example, if the text recognized from the sound content is "wash jeans in standard mode", then the semantic recognition indicates that the target control device is a washing machine, and the control command is to turn on standard mode.

[0122] It should be noted that, in one possible implementation, voice commands may not include a wake word, which can provide users with a more intelligent user experience.

[0123] It is worth noting that the target device includes: a first device, and / or a second device, wherein the first device is a device in the first device group, and the second device is a device in another device group in the network.

[0124] Specifically, the target device may be at least one device in the first device group, and may also include devices from other device groups. Alternatively, the target device may be at least one device from other device groups. That is, the target device can consist of devices from multiple device groups to perform the target task indicated in the user's voice command.

[0125] In one possible design, after confirming that the first device group has obtained the response permission, it sends response feedback information to the user, including at least one of visual feedback information and audio feedback information. For example, the voice indicator light may light up or flash, a beep may be played, and the voice message "Received" may be announced.

[0126] For example, on a balcony, a washing machine and a dryer are stacked together to form one device group, and an electronic clothes drying rack forms another. When a user issues a voice command, "Dry at 30 degrees Celsius for half an hour and then sterilize with ultraviolet light," the two device groups compete for the right to respond. Assuming the device group containing the dryer gains the right to respond, but the dryer does not have voice control functionality, the washing machine's voice control module responds to the user's voice command, and the washing machine announces, "Received, dryer drying temperature set to 30 degrees Celsius, drying time 30 minutes, ultraviolet sterilization mode activated."

[0127] This effectively solves the problem of insufficient precision and stability of the local response mechanism when multiple devices are installed too close together, and also reduces the cost of each device by reducing the number of voice control modules.

[0128] It should also be noted that the voice control module can be configured as a separate, independent device, capable of managing all devices within a preset range, meaning these devices share a single voice control module. The voice control module executes the voice control method provided in this embodiment to control the devices within the device group to respond to user voice commands. This design enables voice control of non-voice-controlled devices, with low modification costs and simple operation.

[0129] The voice control method provided in this embodiment receives user voice commands from each device group and sends master control request information to the network where the device group is located. Then, the central control device or central server in the network determines the first device group to be assigned response permissions based on the master control request information and preset response allocation principles. The allocation result of the response permissions is then fed back to the first device group or all device groups. The first device group or all device groups then receive the first request result fed back from the network and confirm that the first device group has obtained response permissions. The first device group then controls at least one target device to execute the target task indicated by the voice command. This solves the technical problem in the prior art where the proximity wake-up mechanism of voice control fails when multiple devices are too concentrated, thus improving the user experience of the distributed multi-device voice control system.

[0130] Figure 3 This is a flowchart illustrating another voice control method provided in an embodiment of this application. Figure 3 As shown, the specific steps of this voice control method include:

[0131] S301: Receive voice commands issued by the user.

[0132] In this embodiment, there are multiple devices in a space. These devices are divided into several device groups according to a preset grouping principle. Each device group has at least one voice control device or at least one voice control module unit.

[0133] The grouping principles include: each device meeting the preset distance requirements, and / or, functional matching requirements.

[0134] The preset distance requirements include: the distance between each device is less than or equal to the preset distance threshold, such as within 1 meter or within 0.5 meters.

[0135] Understandably, the preset distance requirement can also be that the distance between each device is greater than the preset distance threshold, which is used to connect multiple devices that are far apart but whose functions complement each other.

[0136] Functional combination requirements include: each device working together to complete a preset task. For example, a washing machine and dryer work together to wash and dry dirty clothes. A stove and range hood work together to prevent users from forgetting to turn on the range hood while cooking or forgetting to turn it off after cooking.

[0137] It should be noted that in one possible design, all devices are connected to the same network, such as a local area network (LAN) or an Internet of Things (IoT). This network includes at least one central control device or central server for overall management of the entire network system.

[0138] In another possible design, all voice control devices only need to be connected to the same network. Devices within the group can communicate via wired or wireless connections (such as Bluetooth or Wi-Fi), eliminating the need for each device to be connected to the network system individually. This streamlines the network system, simplifies maintenance, and reduces the complexity and cost of network management. Furthermore, it eliminates the need for a network interface for each device, lowering equipment costs and reducing the overall expense for users.

[0139] In this embodiment, if a device group contains multiple voice control devices or multiple independent voice control module units, to prevent the central control device or central server in the network system from receiving multiple master control request messages from the same device group when deciding which device group has the right to respond to user voice commands, it is necessary to determine a master voice control device or voice control module unit within the same device group.

[0140] S302. In response to the received voice command, send an intra-group master control request to the network where the device group is located or within the device group.

[0141] In this step, the group master request is used to request permission to respond to voice commands within the device group.

[0142] Specifically, after receiving a voice command from a user, if a device group includes multiple voice control devices or multiple voice control module units, the first step is to determine which voice control device will act as the representative of the device group to send the master control request information to the network system.

[0143] At this point, there are two implementation methods in this embodiment:

[0144] One approach involves each voice control device within a group sending a master control request to the network system. The central control device or server in the network then determines the master voice control device within the group based on preset rules. In other words, it decides which voice control device has the authority to respond to voice commands.

[0145] It should be noted that this permission is not the ultimate permission to respond to voice commands, but only the permission to make one of the voice control devices act as the representative of its device group.

[0146] Another method involves each voice control device sending group master control request information to each other. Each voice control device determines which device obtains group master control permissions based on the time it sends and receives the group master control request information.

[0147] S303: Receive group master control requests sent by each voice control device.

[0148] In this step, the intra-group master control request is used to request voice master control permissions within the home device group, which is the device group to which the voice control device belongs.

[0149] Corresponding to the two implementation methods in the previous step, the central control device in the network can receive the group master control request, or each voice control device in the group can receive the group master control request sent by other voice control devices.

[0150] It should be noted that, in order to avoid ambiguity in the interpretation of the flowchart, Figure 3 The example shown only illustrates an implementation where a central control device receives requests from the main control unit within the group.

[0151] S304. Based on the master control requests within each group and the preset master control allocation principles, determine the master control devices within the group that are assigned voice master control permissions.

[0152] In this step, the preset master control allocation principles include: determining the ownership of permissions based on the sending time of the master control request within the group, or determining the ownership of permissions based on the time when the central control device receives the master control request within the group, or determining the ownership of permissions based on the current status of the voice control device (such as whether it is processing another voice control task), or determining the ownership of permissions based on the preset priority of each voice control device.

[0153] S305. Feedback the allocation results of voice master control permissions to the master control device or all voice control devices in the group.

[0154] In this step, if the group master control permission is assigned by the central control device or central server, then this step will be executed by that device; if it is assigned by the device group itself, then the group master control device will report the assignment result of obtaining the group master control permission to other voice control devices in the group.

[0155] S306, Receive the second request result from within the network or device group.

[0156] S307. Based on the result of the second request, determine the master control device within the group that has obtained the permission, so that the master control device within the group responds to the voice command and sends the master control request information to the network.

[0157] In this step, after the master control device within the group is determined, it sends a master control request message to the master control device of the network system on behalf of its group. This master control request message is used to request the group to obtain the final response authority to voice commands.

[0158] S308: Receive master control request information sent by each device group.

[0159] S309. Based on the master control request information and the preset response allocation principle, determine the first device group to be assigned the response permission.

[0160] S310: Feedback the allocation results of response permissions to the first device group or all device groups.

[0161] S311, Receive the first request result from the network feedback.

[0162] For details on the implementation methods, terminology explanations, and working principles of steps S308 to S311, please refer to [link / reference]. Figure 2 S203 to S206 are not described in detail here.

[0163] S312. If the first device group obtains response permission based on the result of the first request, then the first device group controls at least one target device to execute the target task indicated by the voice command.

[0164] In this step, the target device includes: a first device, and / or a second device, wherein the first device is a device in a first device group, and the second device is a device in another device group in the network.

[0165] In one possible design, controlling at least one target device to perform a target task indicated by a voice command includes:

[0166] Use a semantic parsing model to parse speech instructions in order to determine the target task;

[0167] Using a pre-defined control model, the target equipment and control commands are determined based on the target task;

[0168] If the target device includes the first device, then a first control instruction is sent to the first device to enable the first device to complete the target task. The control instruction includes the first control instruction.

[0169] In one possible design, controlling at least one target device to perform the target task indicated by the voice command further includes:

[0170] If the target device includes a second device, then a second control command is sent to the second device to enable the first device to complete the target task. The control command includes the second control command.

[0171] In one possible design, controlling at least one target device to perform a target task indicated by a voice command includes:

[0172] If a preset control model is used to determine that there is no device in the network capable of performing the target task, then a preset language model is used to determine the voice feedback information based on the voice command.

[0173] For example, the content of a voice command is recognized and converted into corresponding text. Then, semantic recognition is performed on the text to extract the target control device. For instance, if the text recognized from the voice content is "wash jeans in standard mode," then semantic recognition identifies the target control device as a washing machine, and the control command is to turn on standard mode.

[0174] or,

[0175] Send users a purchase link for the target device, which is capable of performing the target task. This helps users identify their purchasing needs and addresses the issue of users not knowing what to do when a suitable device to complete voice commands is unavailable, thus improving the user experience.

[0176] The voice control method provided in this embodiment receives user voice commands from each device group and sends master control request information to the network where the device group is located. Then, the central control device or central server in the network determines the first device group to be assigned response permissions based on the master control request information and preset response allocation principles. The allocation result of the response permissions is then fed back to the first device group or all device groups. The first device group or all device groups then receive the first request result fed back from the network and confirm that the first device group has obtained response permissions. The first device group then controls at least one target device to execute the target task indicated by the voice command. This solves the technical problem in the prior art where the proximity wake-up mechanism of voice control fails when multiple devices are too concentrated, thus improving the user experience of the distributed multi-device voice control system.
