Therefore, when a user activates a wake-up word, multiple devices may respond, leaving the user unsure of the next interaction and significantly impacting the user experience. Currently, no effective solution has been proposed to address the problem of multiple voice inputs responding simultaneously. Summary of the Invention

[0024] Example 1

[0025] Figure 1 For an overall flowchart of a distributed voice response method provided in this application embodiment, please refer to [link / reference]. Figure 1The method is applied to a distributed system, which includes multiple devices connected in communication with each other. The distributed voice response method provided in this embodiment can achieve its functionality by having the processor of an electronic device call program code, wherein the program code can be stored in a computer storage medium. This embodiment provides a distributed voice response method, including:

[0026] Step S101: Obtain user input information.

[0027] In this embodiment, the device refers to a device with voice interaction capabilities, such as smart home appliances like air conditioners, televisions, stereos, washing machines, water dispensers, and refrigerators. When multiple devices receive user input, the distributed control system selects a target device to respond to the user's input. The user's input includes voice messages and activation signals generated when the user clicks on a device. The voice messages contain the user's activation word, also known as a wake-up word. The activation signal generated when the user clicks on a device can be a signal generated by clicking on a device with a screen or a button input by the user.

[0028] Step S102: Determine the target device from multiple devices based on the input information and preset rules.

[0029] In this embodiment, the preset rules include: activation device priority principle, default sorting principle, and sound intensity priority principle. When multiple devices receive user input information, the control system selects a single device from among the multiple devices to respond based on the input information and the aforementioned preset rules; this selected device is the target device.

[0030] Step S103: Control the target device to respond to the input information.

[0031] In this embodiment, after the control system selects the target device, it controls the target device to respond to the user, which can avoid the problem of multiple devices responding at the same time.

[0032] In some embodiments, the preset rule includes: prioritizing activated devices; determining a target device from multiple devices based on the input information and the preset rule, so that the target device responds to the input information, includes: when the input information contains a device activation signal, selecting the device corresponding to the activation signal as the target device to respond based on the activation signal and the principle of prioritizing activated devices.

[0033] For example, the device activation priority principle is as follows: if multiple devices receive the same wake word from the user, and the user also clicks to activate one of the multiple devices, then the activated device will be the target device to respond to the user.

[0034] In some embodiments, the preset rules include: a default sorting; determining a target device from multiple devices based on the input information and the preset rules, so that the target device responds to the input information, includes: determining the target device from multiple devices based on the default sorting when the input information does not contain a device activation signal.

[0035] For example, the default sorting principle is as follows: In multi-device scenarios, the default order is: central control device > TV > audio equipment > mobile phone; for instance, if all of the above devices exist in a home, the central control device will activate the voice assistant to respond to the user during voice wake-up. The above sorting rules are not limited; in practical applications, users can set the sorting according to their personal preferences.

[0036] In some embodiments, the input information includes: voice information; the preset rule includes: sound intensity priority; the multiple devices include: multiple devices of the same type; the step of determining a target device from the multiple devices based on the input information and the preset rule, so that the target device responds to the input information, includes: performing an election based on the sound intensity of the voice information obtained by the multiple devices of the same type, selecting the device with the highest sound intensity as the target device, so that the target device responds to the voice information.

[0037] For example, the sound intensity priority principle is as follows: when multiple similar devices simultaneously receive a wake word, the election protocol and rule adaptation are applied according to the sound intensity priority principle. The sound intensity of the wake word received by each device is different. After comparison, the device with the strongest sound intensity of the received wake word responds to the user via broadcast communication, while other devices remain silent.

[0038] In some embodiments, multiple devices of the same type are voice playback devices. If multiple speaker-like devices exist in a user's home, the voice assistant is activated based on the device with the strongest sound pickup.

[0039] In some embodiments, the devices interact with each other via a local area network (LAN) or Bluetooth. The communication method in this embodiment is not limited to LAN, Bluetooth, or other similar technologies.

[0040] In some embodiments, the priority of the activated device is greater than the priority of the default sorting, and the priority of the activated device is greater than the priority of the sound intensity priority.

[0041] In some embodiments, the preset rule includes: prioritizing activated devices; determining a target device from multiple devices based on the input information and the preset rule, so that the target device responds to the input information, includes: when the input information contains a device activation signal, selecting the device corresponding to the activation signal as the target device to respond based on the activation signal and the principle of prioritizing activated devices.

[0042] In some embodiments, the preset rules include: a default sorting; determining a target device from multiple devices based on the input information and the preset rules, so that the target device responds to the input information, includes: determining the target device from multiple devices based on the default sorting when the input information does not contain a device activation signal.

[0043] In some embodiments, the input information includes: voice information; the preset rule includes: sound intensity priority; the multiple devices include: multiple devices of the same type; the step of determining a target device from the multiple devices based on the input information and the preset rule, so that the target device responds to the input information, includes: performing an election based on the sound intensity of the voice information obtained by the multiple devices of the same type, selecting the device with the highest sound intensity as the target device, so that the target device responds to the voice information.

[0044] In some embodiments, multiple devices of the same type are voice playback devices.

[0045] In some embodiments, the devices interact with each other via a local area network or Bluetooth.

[0046] In some embodiments, the priority of the activated device is greater than the priority of the default sorting, and the priority of the activated device is greater than the priority of the sound intensity priority.

[0047] This embodiment provides a distributed voice response method. When a user inputs interactive information, a target device is determined from multiple devices based on the interactive information and preset rules. After the target device is determined, the target device actively responds to the user's interactive voice. This ensures that when the same user has multiple smart devices for voice interaction, only the target device responds to the user, thereby avoiding multiple devices responding at the same time and improving the user experience.

[0048] Example 2

[0049] Based on Embodiment 1, this embodiment illustrates the method described in Embodiment 1 through a specific implementation example. When multiple devices receive user input information, the distributed control system selects a target device to respond to the user's input information. The user's input information includes voice messages from the user and activation signals generated when the user clicks on a device. The voice messages contain the user's activation word, also known as a wake-up word. The activation signal generated when the user clicks on a device can be a signal generated by the user clicking on a device with a screen, or it can be a button signal input by the user.

[0050] Figure 2 Please refer to the schematic diagram of a distributed voice response method provided in the embodiments of this application. Figure 2In a space, there are multiple devices with voice interaction capabilities. These devices are all connected to the same local area network (LAN). The devices communicate with each other using technologies such as LAN and Bluetooth. The devices can exchange data and perform rule-based elections to select a responding device, which then responds to the user.

[0051] For example, such as Figure 2 As shown, the same space contains smart home devices such as a central control unit, air conditioner, television, and speakers. When a user issues an activation word to wake up the device, all smart home devices simultaneously receive the activation word. To prevent these devices from responding to the user at the same time, this embodiment establishes three rules, as follows:

[0052] Rule 1: Device Activation Priority. The principle of device activation priority is as follows: if smart home devices such as central control units, air conditioners, televisions, and audio systems receive the same wake-up word from the user, and the user also presses the voice button on the remote control, then the device corresponding to that remote control will act as the activation device to respond to the user. For example... Figure 2 As shown, when a user utters the activation word and presses the remote control, the smart device bound to the remote control will respond to the user.

[0053] Rule 2: Default Sorting. In multi-device scenarios, the default sorting is: Central Control Device > TV > Audio Devices > Mobile Phone. For example, if a home has a central control device, TV, audio devices, and a mobile phone, the central control device will activate the voice assistant to respond to the user during voice wake-up. If there is no central control device or it is damaged and unresponsive, the TV will activate the voice assistant. If there is neither a central control device nor a TV, or both are damaged and unresponsive, the audio devices will activate the voice assistant. This sorting rule is not fixed; in practice, users can set the default sorting rule according to their personal preferences.

[0054] Rule 3: Sound Intensity Priority. When multiple similar devices receive a wake word simultaneously, the election protocol and rules apply to the sound intensity priority principle. For example, if a user's home has multiple audio devices, when the user issues an activation word to wake them up, the sound intensity of the wake word received by each audio device will vary. After comparison, the audio device with the loudest wake word will actively respond to the interactive voice and interact with the user, while the other audio devices will remain silent.

[0055] Rule 4: Rule 1 >> Rule 2 ≈ Rule 3. When all three of the above scenario rules exist simultaneously, Rule 1 takes precedence, i.e., device activation takes priority.

[0056] The distributed voice response method provided in this embodiment determines the target device from multiple smart devices based on the interaction information and rules one to four when the user inputs interactive information. After the target device is determined, the target device actively responds to the user's interactive voice. This ensures that when the same user has multiple smart devices for voice interaction, only the target device responds to the user, thereby avoiding multiple devices responding at the same time and improving the user experience.

[0057] Example 3

[0058] Figure 3 Please refer to the structural diagram of a distributed voice response device provided in the embodiments of this application. Figure 3 This embodiment provides a distributed voice response device 200, including:

[0059] Module 201 is used to acquire user input information;

[0060] The determination module 202 is used to determine the target device from multiple devices based on the input information and preset rules;

[0061] The control module 203 is used to control the target device to respond to the input information.

[0062] It should be noted that the acquisition module 201 in this embodiment can be used to execute step S101 in this application embodiment, the determination module 202 in this embodiment can be used to execute step S102 in this application embodiment, and the control module 203 in this embodiment can be used to execute step S103 in this application embodiment.

[0063] The examples and application scenarios implemented by the above modules and corresponding steps are the same, but are not limited to the content disclosed in the above embodiments.

[0064] In some embodiments, the preset rules in the determining module 202 include: prioritizing activated devices; determining the target device from multiple devices based on the input information and the preset rules, so that the target device responds to the input information, includes: if the input information contains a device activation signal, selecting the device corresponding to the activation signal as the target device to respond based on the activation signal and the principle of prioritizing activated devices. For example, if multiple devices receive the same wake word from the user, and the user also activates one of the multiple devices, then that activated device will respond to the user as the target device.

[0065] In some embodiments, the preset rules in the determining module 202 include: a default sorting; determining the target device from multiple devices based on the input information and the preset rules, so that the target device responds to the input information, includes: determining the target device from multiple devices based on the default sorting when the input information does not contain a device activation signal. For example, in a multi-device scenario, the default sorting is: central control device > television > audio equipment > mobile phone; for example, if all of these devices exist in a home, the central control device will activate the voice assistant to respond to the user during voice wake-up. The above sorting rules are not limited; in practical applications, users can set the sorting according to their personal preferences.

[0066] In some embodiments, the input information acquired by the acquisition module 201 includes: voice information; the preset rule includes: sound intensity priority; the multiple devices include: multiple devices of the same type; the step of determining a target device from the multiple devices based on the input information and the preset rule, so that the target device responds to the input information, includes: electing the device with the highest sound intensity based on the sound intensity of the voice information acquired by the multiple devices of the same type, so that the target device responds to the voice information. For example, multiple devices of the same type simultaneously receive a wake-up word; the election protocol and rule adaptation are applied according to the sound intensity priority principle. The sound intensity of the wake-up word received by each device is different; after comparison, the device with the highest sound intensity of the received wake-up word responds to the user, while other devices remain silent.

[0067] In some embodiments, multiple devices of the same type are voice playback devices. For example, when multiple speaker-type devices in a user's home simultaneously receive the wake word, the speaker with the strongest pickup volume activates the voice assistant for recognition.

[0068] In some embodiments, the devices interact with each other via a local area network or Bluetooth.

[0069] In some embodiments, the priority of the activated device is greater than the priority of the default sorting, and the priority of the activated device is greater than the priority of the sound intensity priority.

[0070] This embodiment provides a distributed voice response method. When a user inputs interactive information, a target device is determined from multiple devices based on the interactive information and preset rules. After the target device is determined, the target device actively responds to the user's interactive voice. This ensures that when the same user has multiple smart devices for voice interaction, only the target device responds to the user, thereby avoiding multiple devices responding at the same time and improving the user experience.
