Description

Technical Field

[0001] This disclosure relates to the field of terminal technology, and in particular to a voice device response method, apparatus, electronic device, storage medium, and chip. Background Technology

[0002] With the continuous development of IoT technology, users can more easily issue commands to devices. For example, users can wake up electronic devices by saying a "wake word," thereby enabling interaction between users and electronic devices.

[0003] Currently, with the continuous increase in smart devices, collaborative wake-up functionality has emerged to ensure that users can interact normally with as many devices as possible. However, when collaboratively waking up devices, if there are significant differences in wake-up latency, some devices may have low wake-up latency, but they still need to wait for other devices to wake up before receiving the wake-up data packet, resulting in slower device response and a reduced user experience. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this disclosure provides a device response method, apparatus, electronic device, storage medium, and chip.

[0007] After detecting that the voice wake-up command contains a preset wake-up word, a first energy value is generated according to a preset sound source energy algorithm, wherein the first energy value represents the sound energy of the voice wake-up command when it propagates from the sound source to the first voice device;

[0008] Send a first wake-up data packet to at least one second voice device, the first wake-up data packet including the first energy value;

[0009] After receiving pre-wake-up data packets sent by all second voice devices, it is determined whether the first voice device meets the preset response conditions based on the pre-wake-up data packets and preset response conditions. The pre-wake-up data packets include a second energy value, which represents the sound energy when the voice wake-up command is transmitted from the sound source to the second voice device.

[0010] If the first voice device does not meet the preset response conditions and does not receive a second wake-up data packet from any of the second voice devices within a predetermined time, then the first voice device responds to the voice wake-up command, and the second wake-up data packet includes the second energy value.

[0036] The response module is configured to respond to the voice wake-up command if the first voice device does not meet the preset response conditions and does not receive a second wake-up data packet from any of the second voice devices within a predetermined time.

[0041] According to a sixth aspect of the present disclosure, an electronic device is provided, comprising:

[0047] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: acquiring a voice wake-up command issued by a user through a first voice device; after detecting that the voice wake-up command contains a preset wake-up word, generating a first energy value according to a preset sound source energy algorithm, wherein the first energy value represents the sound energy of the voice wake-up command when it propagates from the sound source to the first voice device; sending a first wake-up data packet to at least one second voice device, the first wake-up data packet including the first energy value; after receiving pre-wake-up data packets sent by all second voice devices, determining whether the first voice device meets the preset response conditions according to the pre-wake-up data packets and preset response conditions, wherein the pre-wake-up data packets include a second energy value, the second energy value representing the sound energy of the voice wake-up command when it propagates from the sound source to the second voice device; if the first voice device does not meet the preset response conditions and does not receive a second wake-up data packet sent by any of the second voice devices within a predetermined time, then the first voice device responds to the voice wake-up command, the second wake-up data packet including the second energy value. Thus, during the collaborative wake-up process of the first voice device and the second voice device, before the second voice device is woken up, the second voice device sends a pre-wake-up data packet in advance, enabling the first voice device to make a response decision in advance based on the pre-wake-up data packet, so as to respond quickly, instead of having the first voice device wait until the second voice device is woken up before making a response decision, thereby improving the response speed and user experience.

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0059] It should be noted that all actions involving the acquisition of signals, information, or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where the application is located, and with the authorization granted by the owner of the relevant device.

[0060] In related technologies, when a user coordinates the wake-up of multiple voice devices in the same network, if one voice device is woken up, it must wait until it receives wake-up data packets from other voice devices in the group or if a timeout occurs before it can make a decision and determine whether to respond. This results in a relatively long wait time after each wake-up when there are remote voice devices, such as when a remote device is not woken up during each wake-up attempt, or when there are devices with high wake-up latency, before deciding whether to respond. This leads to a slow response time for the voice device and a poor user experience.

[0061] To address the aforementioned issues, this embodiment provides a method, apparatus, electronic device, storage medium, and chip for responding to voice device responses, which can effectively improve the response speed of voice devices.

[0062] Figure 1 This is a flowchart illustrating a voice device response method according to an exemplary embodiment, such as... Figure 1 As shown, the voice device response method can be applied to a first voice device. The method may include the following steps:

[0063] In step S11, the user's voice wake-up command is obtained.

[0064] For example, such as Figure 2 As shown, the first voice device can be located in a preset network group 100. This preset network group 100 can be formed by multiple voice devices accessing the same local area network (LAN). The multiple voice devices within the group can communicate with each other. The multiple voice devices may include the first voice device 110 and at least one second voice device 120. Optionally, the multiple voice devices include, but are not limited to: mobile terminals (such as smartphones, personal computers, etc.), smart TVs, smart speakers, smart clothes racks, smart refrigerators, smart wearable devices, etc. Optionally, the multiple devices in the preset network group 100 can be located in the same space or in different spaces, for example, one at home and another at the office; this is not limited here.

[0065] In some implementations, one voice device in the preset network can be arbitrarily selected as the first voice device, and other voice devices in the preset network besides the first voice device can be selected as the second voice devices. The first voice device can monitor in real time whether it receives a voice wake-up command from the user. When the first voice device receives a voice wake-up command, it can wake up. It can be understood that waking up the device can be regarded as starting the device; when the device is woken up, it indicates that the device has completed the startup process.

[0066] Specifically, when the voice wake-up command contains a preset wake-up word, and the voice device detects the preset wake-up word, the voice device can be triggered to wake up.

[0067] In step S12, after detecting that the voice wake-up command contains a preset wake-up word, a first energy value is generated according to a preset sound source energy algorithm, wherein the first energy value represents the sound energy when the voice wake-up command propagates from the sound source to the first voice device.

[0068] For example, if the first voice device detects that a user's voice command contains a preset wake-up word "XX classmate", then the voice device can trigger a wake-up action and generate a first energy value according to a preset sound source energy algorithm. In other words, the first voice device can determine whether it is awake by detecting whether the voice wake-up command contains a preset wake-up word.

[0069] Understandably, since the first energy value represents the sound energy when the voice wake-up command travels from the sound source to the first voice device, and the amount of sound energy received by the first voice device is related to the distance between the sound source and the first voice device, this first energy value can be used to determine the distance between the sound source and the first voice device. For example, the larger the first energy value, the closer the sound source is to the first voice device; the smaller the first energy value, the farther the sound source is from the first voice device. Here, the sound source is the user.

[0070] Optionally, a preset sound source energy algorithm can be pre-stored in the first voice device.

[0071] In step S13, a first wake-up data packet is sent to at least one second voice device, the first wake-up data packet including a first energy value.

[0072] In some implementations, the first voice device may generate a first wake-up data packet based on a first energy value and send the first wake-up data packet to the second voice device.

[0073] In some implementations, the first wake-up data packet may include, in addition to the first energy value, device information of the first voice device, the wake-up time detected by the first voice device, and the transmission initiation time for the first wake-up data packet. Optionally, the device information may be encrypted and may include, but is not limited to, device type information, device identifier (deviceId), and product serial number (SN). Optionally, the aforementioned wake-up time may specifically be a recorded wake-up timestamp, and the aforementioned transmission initiation time may also be a transmission initiation timestamp.

[0074] In step S14, after receiving the pre-wake-up data packets sent by all the second voice devices, it is determined whether the first voice device meets the preset response conditions based on the pre-wake-up data packets and the preset response conditions. The pre-wake-up data packets include a second energy value, which represents the sound energy when the voice wake-up command is transmitted from the sound source to the second voice device.

[0075] In some implementations, the first wake-up data packet can be used by the second voice device to send a pre-wake-up data packet back to the first voice device when the second voice device receives the first wake-up data packet. For example, when the second voice device receives the first wake-up data packet, it can detect whether it has been woken up. If it has not been woken up, it indicates that the second voice device may not have received the user's voice wake-up command for various reasons. In this case, the second voice device can send a pre-wake-up data packet back to the first voice device in advance.

[0076] The implementation method for the second voice device to detect whether it has been woken up can refer to the method of the first voice device detecting a preset wake-up word, so it will not be described in detail here.

[0077] After receiving the pre-wake-up data packets sent by all the second voice devices, the first voice device can determine whether the first voice device meets the preset response conditions based on the pre-wake-up data packets and the preset response conditions.

[0078] Optionally, the preset response condition can be to determine whether the second energy value in the pre-wake-up data packet is within a specified range. If it is, the preset response condition is met; if it is not, the preset response condition is not met.

[0079] In other embodiments, the pre-wake data packet may also include wake-up object information. When the first voice device receives the pre-wake data packet sent by the second voice device, it can determine whether the first voice device is the device that the user needs to respond to based on the wake-up object information in the pre-wake data packet. If so, it can determine whether the first voice device meets the preset response conditions. As an example, the first voice device can compare the device ID in the voice wake-up command with its own ID. If the two IDs match, it can determine whether the first voice device meets the preset response conditions.

[0080] In step S15, if the first voice device does not meet the preset response conditions and does not receive a second wake-up data packet from any of the second voice devices within a predetermined time, the first voice device responds to the voice wake-up command, and the second wake-up data packet includes a second energy value.

[0081] Optionally, the second wake-up data packet is sent by the second voice device after detecting that the voice wake-up command contains a preset wake-up word.

[0082] The second wake-up data packet and the pre-wake-up data packet can contain the same data. The difference between the two is that the data packets are different types. The second wake-up data packet is sent after the second voice device is woken up, while the pre-wake-up data packet is sent after receiving the first wake-up data packet, without waiting for the second voice device to be woken up.

[0083] As an example, if the first voice device does not receive the second wake-up data packet sent by the second voice device within a preset time period, it indicates that the first voice device is unsure whether any device in the preset network responds to the user's voice wake-up command. To avoid any device in the preset network failing to respond to the user's voice wake-up command, the first voice device can respond to the voice wake-up command to inform the user of the device's response status. For example, if the user issues the voice wake-up command "XX, turn on the second voice device," the first voice device, after receiving the voice wake-up command first, sends the first wake-up data packet to the second voice device. However, if it does not receive the second wake-up data packet within the preset time period, it can directly respond to the user "No second voice device detected."

[0084] In some implementations, the method may further include: if the first voice device meets preset response conditions, then the first voice device responds to the voice wake-up command.

[0085] In some implementations, the method may further include:

[0086] If a second wake-up data packet sent by the second voice device is received within a preset time period, then the detection of whether the second wake-up data packet sent by the second voice device has been received is stopped.

[0087] For example, if the first voice device receives the second wake-up data packet sent by the second voice device within a preset time period, it indicates that the first voice device already knows whether the second voice device has responded and does not need to make a response decision itself. Therefore, it can stop detecting whether the second wake-up data packet has been received, thereby reducing power consumption.

[0088] As can be seen, in this embodiment, the user's voice wake-up command is obtained through a first voice device; after detecting that the voice wake-up command contains a preset wake-up word, a first energy value is generated according to a preset sound source energy algorithm, wherein the first energy value represents the sound energy of the voice wake-up command when it propagates from the sound source to the first voice device; a first wake-up data packet is sent to at least one second voice device, the first wake-up data packet including the first energy value; after receiving pre-wakeup data packets sent by all second voice devices, it is determined whether the first voice device meets the preset response conditions according to the pre-wakeup data packets and preset response conditions, wherein the pre-wakeup data packets include a second energy value, the second energy value representing the sound energy of the voice wake-up command when it propagates from the sound source to the second voice device; if the first voice device does not meet the preset response conditions and does not receive a second wake-up data packet sent by any second voice device within a predetermined time, then the first voice device responds to the voice wake-up command, the second wake-up data packet including the second energy value. Thus, during the collaborative wake-up process of the first voice device and the second voice device, before the second voice device is woken up, the second voice device sends a pre-wake-up data packet in advance, enabling the first voice device to make a response decision in advance based on the pre-wake-up data packet, so as to respond quickly, instead of having the first voice device wait until the second voice device is woken up before making a response decision, thereby improving the response speed and user experience.

[0089] Figure 3 This is a flowchart illustrating a voice device response method according to another exemplary embodiment, such as... Figure 3 As shown, the voice device response method is used for a second voice device. At least one second voice device and the first voice device are connected to a local area network and are in the same preset network group. The method may include the following steps:

[0090] In step S21, upon receiving the first wake-up data packet sent by the first voice device, a second energy value is generated according to a preset sound source energy algorithm. The second energy value represents the sound energy of the voice wake-up command issued by the user when it propagates from the sound source to the second voice device. The first wake-up data packet includes the first energy value, which represents the sound energy of the voice wake-up command when it propagates from the sound source to the first voice device.

[0091] In step S22, a pre-wake-up data packet is sent to the first voice device. The pre-wake-up data packet includes a second energy value. The pre-wake-up data packet is used by the first voice device to determine whether the first voice device meets the preset response conditions based on the pre-wake-up data packet and the preset response conditions, and to respond to the voice wake-up command if the first voice device meets the preset response conditions.

[0092] In step S23, after detecting that the voice wake-up command contains a preset wake-up word, a second wake-up data packet is sent to the first voice device. The second wake-up data packet includes a second energy value. The second wake-up data packet is used by the first voice device to respond to the voice wake-up command if the preset response conditions are not met and no second wake-up data packet is received from any second voice device within a predetermined time.

[0093] For example, a user can issue a voice wake-up command to a device in a preset network. The first voice device can respond to the received voice wake-up command, wake up, and then send a first wake-up data packet to the second voice device. When the second voice device receives the first wake-up data packet, it can detect whether it has been woken up. If it has not been woken up, it indicates that the second voice device may not have received the user's voice wake-up command, or that the time of receiving the voice wake-up command is later than that of the first voice device due to network latency.

[0094] Following the example above, under normal circumstances, the first voice device needs to receive the wake-up data packet fed back by the second voice device after it is woken up in order to make a response decision. Here, in order not to hinder the first voice device, which is woken up first, from making a wake-up decision, a pre-wake-up data packet can be sent to the first voice device in advance before the second voice device is woken up, so that the first voice device can make a response decision in advance.

[0095] More specific implementations of steps S21 to S23 can be found in steps S11 to S15 of the above embodiments, and will not be repeated here.

[0096] Figure 4 This is a timing diagram illustrating a voice device response method according to an exemplary embodiment, such as... Figure 4 As shown, the voice device response method can be applied to a preset network, which may include a first voice device and at least one second voice device. The method may include:

[0097] In step S31, the first voice device acquires the voice wake-up command issued by the user.

[0098] In step S32, after detecting that the voice wake-up command contains a preset wake-up word, the first voice device generates a first energy value according to a preset sound source energy algorithm, wherein the first energy value represents the sound energy when the voice wake-up command propagates from the sound source to the first voice device.

[0099] In step S33, the first voice device sends a first wake-up data packet to at least one second voice device, the first wake-up data packet including a first energy value.

[0100] In step S34, after receiving the first wake-up data packet, the second voice device generates a second energy value according to a preset sound source energy algorithm, wherein the second energy value represents the sound energy when the voice wake-up command is transmitted from the sound source to the second voice device.

[0101] In step S35, the second voice device sends a pre-wake-up data packet to the first voice device, the pre-wake-up data packet including a second energy value.

[0102] In step S36, after detecting that the voice wake-up command contains a preset wake-up word, the second voice device sends a second wake-up data packet to the first voice device, wherein the second wake-up data packet includes a second energy value.

[0103] In step S37, after receiving all the pre-wake-up data packets sent by the second voice devices, the first voice device determines whether the first voice device meets the preset response conditions based on the pre-wake-up data packets and the preset response conditions.

[0104] In step S38, if the first voice device meets the preset response conditions, the first voice device responds to the voice wake-up command.

[0105] In step S39, if the first voice device does not meet the preset response conditions and does not receive a second wake-up data packet sent by any of the second voice devices within a predetermined time, then the first voice device responds to the voice wake-up command.

[0106] The specific implementation of steps S31 to S39 in this embodiment can be referred to steps S11 to S15 and steps S21 to S23 in the above embodiment, so they will not be repeated here.

[0107] For example, such as Figure 6 As shown, in practical applications, the specific implementation process of the device response method in this embodiment can be as follows:

[0108] At time T0, the user issues a voice wake-up command.

[0109] At time T1, the first voice device is woken up and sends a first wake-up data packet to the second voice device, wherein the first wake-up data packet contains a first energy value.

[0110] At time Ta, the second voice device receives the first wake-up data packet, then obtains the second energy value obtained at time Ta, and replies with a pre-wake-up data packet to the first voice device based on the second energy value.

[0111] At time T2, the second voice device is woken up and sends a second wake-up data packet to the first voice device. The second wake-up data packet also includes a second energy value.

[0112] At time Tb, the first voice device receives the pre-wake-up data packet and makes a decision based on the pre-wake-up data packet.

[0113] If the decision is for the first voice device to respond, then the first voice device will respond immediately.

[0114] If the decision is for the second voice device to respond, then continue waiting for the second wake-up data packet from the second voice device. If the second wake-up data packet is received at time Tc, then the first voice device does not respond. If the second wake-up data packet is not received after time Tc, then the first voice device responds.

[0115] As can be seen, by using pre-wake packets, when the first voice device wakes up with a fast wake-up engine, the first voice device can make decisions in advance based on the pre-wake data packets fed back by the second voice device. Therefore, when the device front-end response latency is large, the response latency of collaborative wake-up can be reduced. Specifically, the advance time ΔT = diff_t2 - diff_t1 is approximately increased. This effectively improves the device's response speed and provides users with a better user experience.
