Detailed ways

Currently, electronic devices deployed with voice assistants can support user voice interaction operations, such as intelligent dialogue or instant question-and-answer voice interaction operations.

In practical applications, there are scenarios where voice interaction operations need to be performed across multiple devices. In related technologies, the execution delay of voice commands across devices is relatively high.

In addition, according to the network characteristics and network deployment conditions supported by different electronic devices, there are cases where voice commands are executed in heterogeneous networks. For example, mobile phones have Wi-Fi communication capabilities and Bluetooth communication capabilities, watches have Bluetooth communication capabilities, and TVs have Wi-Fi communication capability. In the case of transmission of voice commands across heterogeneous networks, cloud communication solutions are usually used to realize device interconnection. Voice commands between electronic devices need to be transferred through the cloud to achieve cross-device execution, resulting in high delays in the execution of voice commands across devices. Latency is prominent. In the case of transmission of voice commands across heterogeneous networks, each electronic device needs to be able to access the cloud, which requires high performance of electronic devices.

Based on this, in various embodiments of the present application, the first electronic device determines the network topology map in response to the first voice instruction, and determines the first transmission path based on the network topology map; generates the second transmission path based on the first voice instruction and the first transmission path. A message; and sending a first message to a third electronic device located at the next hop of the first electronic device in the first transmission path; the first voice command is used to instruct the second electronic device to perform a first operation; the first transmission path represents A message transmission path from the first electronic device to the second electronic device via at least one third electronic device; each third electronic device in the at least one third electronic device receives the first message, and transmits the message to the corresponding location in the first transmission path The electronic device next hop of the third electronic device sends the first message; the first message is sent to the corresponding third electronic device by the electronic device located at the previous hop of the corresponding third electronic device in the first transmission path; The second electronic device receives the first message, and executes the first operation in response to the first message; the first message is sent to the second electronic device by a third electronic device that is a hop above the second electronic device in the first transmission path. In this way, in the cross-device execution scenario, the transmission of voice command-related operation requests and operation responses between the wake-up device and the target device can be realized, which greatly reduces the delay of voice command cross-device execution and improves cross-device Execution efficiency.

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

First, a description of the cross-device execution scenario:

Combining with the schematic diagram of network topology composed of multiple devices shown in Figure 1, multiple devices support interconnection and intercommunication based on short-distance wireless communication methods such as Bluetooth and Wi-Fi or other wireless communication methods, and each device has A voice assistant is installed to support the user to input voice commands, and to support the transmission of corresponding operation instructions based on voice commands across devices. In the cross-device execution scenario, the wake-up device is the device that receives the voice command, and the target device is the device that executes the voice command. For example, in Figure 1, watch A receives the voice command "turn up the air conditioner by 1 degree", then the wake-up device corresponding to the voice command is watch A, and the corresponding target device is air conditioner D.

Usually, after the voice command is issued, a corresponding message transmission process that occurs is a transmission process of a request message about the voice command, and the corresponding message transmission direction is from the wake-up device to the target device. After the target device receives the corresponding request message and performs the operation indicated by the voice command, another message transmission process may also occur, that is, the transmission process of the response message about the voice command. The corresponding message transmission direction is from the target device to the A wake-up device is used to feed back the execution result of the target device to the operation to the wake-up device. In actual application, the above-mentioned first message transmission process will inevitably occur, and the above-mentioned second message transmission process may or may not occur. For example, in combination with the above example of the voice command "turn up the air conditioner by 1 degree", the request message about "turn up the air conditioner by 1 degree" is transmitted from watch A to air conditioner D, after the operation of raising the temperature by 1 degree is performed , the air conditioner D can also choose to generate a response message indicating that the relevant operation has been performed, and transmit the response message from the air conditioner D to the watch A, so that the corresponding "air conditioner has been turned up by 1 degree" will be given on the watch A Voice prompt or text prompt.

Next, combined with the cross-device execution scenario provided above, the information transmission method in the cross-device execution process is described in detail:

FIG. 2 is a schematic diagram of an implementation process of the information transmission method provided by the embodiment of the present application, wherein the execution subject of the process includes but is not limited to electronic devices such as mobile phones, tablets, smart watches, and smart home appliances. The information transmission method shown in Figure 2 is applied to electronic device A, including:

Step 201: Determine electronic device B based on the first transmission path corresponding to the first voice instruction.

Wherein, the first message generated based on the first voice command includes operation request information or operation response information about the first voice command, and the first transmission path represents the wake-up device (that is, the source device) from the first voice command , a message transmission path from at least one intermediate device to the target device (that is, the execution device). For the convenience of understanding, the source device of the first voice command is described as the wake-up device, and the execution device of the first voice command is described as the target device. Electronic device A can be understood as any electronic device on the first transmission path, including but not limited to: the wake-up device, the target device, and the electronic device between the wake-up device and the target device on the first transmission path. The electronic device B represents the electronic device located at the next hop of the electronic device A in the transmission direction of the first message in the first transmission path, wherein, for the operation request information about the first voice instruction, the corresponding The message transmission direction is the transmission path direction from the wake-up device to the target device, and for the operation response information about the first voice command, the corresponding message transmission direction is the transmission path direction from the target device to the wake-up device. The first voice instruction is used to instruct the target device, that is, the target device to perform a first operation. For example, in the network topology shown in Figure 1, watch A receives the voice command "turn up the air conditioner by 1 degree", then the wake-up device corresponding to the voice command is watch A, and the corresponding target device is air conditioner D.

In practical applications, the first transmission path is carried in the first message and may be represented by a field in the first message. In practical applications, based on the network topology example diagram composed of multiple devices shown in Figure 1, taking the first transmission path as "watch A-mobile phone B-air conditioner D" as an example, the field value of the corresponding field can be "[A, B, D]", here, "A", "B" and "D" used to identify the corresponding electronic device can also be characterized as the corresponding electronic device ID (ID, Identity document).

Step 202: Send a first message to electronic device B.

In this embodiment, the next-hop electronic device is determined based on the first transmission path carried in the first message, and the first message is sent to the determined electronic device. In this way, in the cross-device execution scenario, voice The transmission of instruction-related operation requests and operation responses between the wake-up device and the target device greatly reduces the delay in cross-device execution of voice commands and improves the execution efficiency of cross-device execution.

Wherein, in an embodiment, the first transmission path represents a transmission path formed by at least three electronic devices. The communication modes supported by the wake-up device and the target device may be the same or different.

In practical applications, in the case of a heterogeneous network, the first transmission path represents a message transmission path formed by at least three electronic devices; wherein, the communication modes supported by the wake-up device and the target device may be the same or different. same. In one embodiment, with reference to the network topology example diagram composed of multiple devices shown in Figure 1, the first transmission path "watch A-mobile phone B-air conditioner D" is represented as a transmission path composed of three electronic devices, wherein the watch A only has Bluetooth communication capabilities, mobile phone B has Wi-Fi communication capabilities and Bluetooth communication capabilities, and air conditioner D has Wi-Fi communication capabilities. The communication methods supported by the corresponding wake-up device and the target device are different. In the above, the information transmission between the watch A and the mobile phone B is based on the Bluetooth communication capability, and the information transmission between the mobile phone B and the air conditioner D is based on the Wi-Fi communication capability, so as to realize cross-device execution in a heterogeneous network. Based on the first transmission path carried by the first message, the information transmission in the heterogeneous network is realized. When the wake-up device and the target device do not support mutual communication, cross-device execution can still be realized without going through the cloud. In this way, It is no longer required that every electronic device in the heterogeneous network has the ability to go to the cloud, which reduces the software and hardware requirements for electronic devices.

As mentioned above, the request message and the response message corresponding to the first voice command correspond to different message transmission directions in the first transmission path. Therefore, in an embodiment, before the electronic device B is determined, the The method also includes:

Based on the type of the first message, determine the transmission direction of the first message; wherein,

The type of the first message includes a request message about the first operation or a response message about the first operation.

Here, the type of the first message may be a request message about the first operation, and the transmission direction of the first message is from the source device to the target device. The type of the first message may be a response message about the first operation, and the transmission direction of the first message is from the target device to the source device. For the request message, electronic device A is looking forward to the first transmission path, so as to determine electronic device B. For the response message, electronic device A reversely searches the first transmission path, so as to determine electronic device B.

For example, the first transmission path is characterized as [A, B, D]. When the type of the first message is a request message, electronic device A (namely electronic device B) is searching for the first transmission path [A, B, D], and determines that electronic device B is D. In the case that the type of the first message is a response message, electronic device A (ie, electronic device B) reversely searches the first transmission path [A, B, D], and determines that electronic device B is A.

In this way, based on the message type of the first message carrying the first transmission path, bidirectional search for a transmission path between the wake-up device and the target device can be realized.

In practical applications, the message type may be identified in a relevant field of the first message, so as to facilitate the electronic device to determine the message transmission direction. Based on this, in an embodiment, before the determining the transmission direction of the first message, the method further includes:

Determine the transmission direction of the first message based on the first field carried in the first message; wherein,

The first field characterizes the type of the first message.

Here, the first message carries at least one first field representing the type of the first message, and the electronic device determines that the type of the first message is a request message about the first operation or a message about the first operation based on reading the first field. Respond to the message, so as to determine the transmission direction of the first message.

Here, the form of the first field includes but is not limited to the following forms:

Characterize the field of the first message type; for example, 0 is a request message, 1 is a response message;

Characterize the identification field of the source device of the first message and/or the identification field of the destination device of the first message; for example, the ID of the source device A, based on the ID of the source device A as the identification field and the first transmission path [A, B, D], it can be determined that the first message is a request message.

In practical applications, the electronic device may also determine the type of the first message by analyzing the first voice instruction carried in the message content carried in the first message. Specifically, the first message carries the message content related to the first voice instruction, and the message content of different types of first messages is different. For example, the format of the request message is uncertain, while the response message is "executed", " The text content of settings such as "opened" or the determined format such as "the washing machine has performed the washing task" and "the TV has performed the downloading task". At this point, the message content can be considered as a first field.

Next, this scheme is further described for the case where electronic device A is the wake-up device, the target device, or an intermediate electronic device located between the wake-up device and the target device on the first transmission path:

First, for the case where electronic device A is the wake-up device, that is, the case where electronic device A is the source device of the first voice command, in a corresponding embodiment, before determining electronic device B, the method further includes:

receiving the first voice instruction;

determining the first transmission path based on the target device corresponding to the first voice command and the set network topology;

Constructing the first message based at least on the first voice instruction and the first transmission path; wherein,

The first message is used to request the target device to perform the first operation.

Here, for the wake-up device, the voice of the user is collected by a voice collection module such as a microphone, so as to receive the first voice instruction, and the first transmission is determined based on the first voice instruction indicating the target device performing the first operation and the set network topology map. path, and constructing the first message based at least on the first voice instruction and the first transmission path.

Here, the set network topology graph represents the network topology graph of the network where electronic device A is located, and may also be called a network topology snapshot. In a heterogeneous network, the network topology map can reflect whether communication is supported between nodes.

Here, the first message at least carries the first voice instruction and the first transmission path. Table 1 shows an example format of the first message.

Table 1

Source Device ID

Transaction ID

first transmission path

Message content

in,

The target device ID characterizes the electronic device ID of the node to which the first message is to be sent;

The source device ID characterizes the electronic device ID of the node that generated the first message;

The transaction ID is used to uniquely identify the request message and the corresponding response message. For example, if the transaction ID of the request message is 1, the transaction ID of the corresponding response message is also 1;

The first transmission path represents a transmission path formed by at least two electronic devices;

The message content is used to carry request content or response content related to the first voice instruction.

Here, electronic device A determines the first transmission path corresponding to the first voice instruction, and constructs a request message for the first voice instruction based at least on the basis of the first transmission path, so that electronic device A determines according to the corresponding first transmission path The next-hop electronic device B correspondingly sends the first message to the electronic device B, thereby realizing message transmission.

In some application scenarios, one voice command may correspond to more than two target devices. Based on this, in one embodiment, the wake-up device determines based on at least two target devices corresponding to the first voice command and the set network topology map. At least two first transmission paths; constructing a first message based at least on the first voice instruction and the at least two first transmission paths.

That is to say, this solution is also applicable when one voice command corresponds to more than two target devices.

For example, the mobile phone receives the voice command "Turn off all electrical appliances in the bedroom". At this time, the target devices include two electronic devices, the TV and the air conditioner. Then, the two first transmission paths from the mobile phone to the TV and from the mobile phone to the air conditioner are correspondingly determined. Then, a first message is correspondingly generated, and the first message is sent to the next-hop electronic device B of the two first transmission paths, thereby completing cross-device multi-device execution.

Secondly, for the case where electronic device A is the target device, that is, the case where electronic device A is the target device of the first voice instruction, in an embodiment, before the electronic device B is determined, the method further includes:

Constructing the first message based at least on the execution result of the first operation and the first transmission path; wherein,

The first message represents an execution response to the first operation.

Here, for the target device, after receiving the request message corresponding to the first voice command, execute the first operation indicated by the first voice command, obtain the execution result of the first operation, and at least based on the execution result of the first operation and the first Transmission path, constructing the first message. Here, the first transmission path may be the transmission path information extracted from the request message, or the transmission path information after reverse processing. , each electronic device is searching for the first transmission path forward.

Here, electronic device A constructs the first message representing the execution response of the first operation at least based on the first transmission path, so that electronic device A determines the next-hop electronic device B according to the corresponding first transmission path, and sends electronic device B Correspondingly sending the first message, so as to realize the transmission of the message.

Again, for the case that electronic device A is an intermediate device, that is, the electronic device A is an intermediate electronic device located between the wake-up device and the target device on the first transmission path, in an embodiment, in the determination of the electronic device Before B, the method also includes:

receiving the first message; wherein,

The first message is sent by an electronic device located one hop above the electronic device A in the transmission direction of the first message in the first transmission path.

Here, the electronic device A is an intermediate device serving as an intermediate node of information transmission, and receives the first message sent from the electronic device at the last hop in the message transmission direction in the first transmission path. For example, based on the network topology example diagram composed of multiple devices shown in FIG. 1 , taking the first transmission path as "watch A-mobile phone B-air conditioner D" as an example, mobile phone B receives the first message from watch A.

In an embodiment of the present application, the determination of electronic device B includes:

determining whether the target device of the first message is the electronic device A;

If the target device of the first message is not the electronic device A, determine the electronic device B.

Here, electronic device A judges whether the target device of the first message is electronic device A on the first transmission path, and if the judgment result indicates that the target device of the first message is not electronic device A, electronic device A needs to forward the message , determining a next-hop electronic device B based on the first transmission path.

Here, in the case where the judgment result indicates that the target device of the first message is electronic device A, if the first message represents a request message about the first voice command, then electronic device A, as the target device corresponding to the first voice command, executes The first operation indicated by the request message; if the first message represents a response message about the first voice command, then after receiving the response message, electronic device A gives a corresponding voice prompt or text prompt based on the response message, and ends the first operation. The execution process related to the voice command.

As mentioned above, the first transmission path is generated based on the target device corresponding to the first voice command and the set network topology map. In the embodiment of the present application, a method for generating a network topology map is also provided. The following describes the network topology The method of generating the graph is explained:

In an embodiment, before the determination of the electronic device B, the method further includes:

Broadcasting a first request; the first request is used to request each electronic device C in at least one electronic device C to report a neighbor electronic device list; the electronic device C represents the neighbor electronic device of the electronic device A;

Receive the neighbor electronic device list reported by each electronic device C in the at least one electronic device C; the neighbor electronic device list reported by the electronic device C includes information for describing the neighbor electronic device of the corresponding electronic device C and the corresponding electronic device C. The list of neighboring electronic devices received by device C.

Here, electronic device A and at least one electronic device C support at least one same communication mode.

In practical application, it can be understood that each electronic device in the network topology broadcasts the first request, and the electronic device that receives the first request reports its corresponding neighbor electronic device list to the electronic device that broadcasts the first request. Here, the reported neighbor electronic device list includes information describing the neighbor electronic device of the electronic device and the neighbor electronic device list received by the electronic device itself, wherein the neighbor electronic device can be understood as an electronic device that supports the same communication capability as the electronic device . In this way, the first request is issued layer by layer from one electronic device, and finally each electronic device in the network topology receives the first request, and based on the first request collects its corresponding neighbor electronic device list, and then each The neighbor electronic device list collected by the electronic device is reported layer by layer, and finally passed back to the electronic device that initiated the first request, and the electronic device that initiated the first request synthesizes all the neighbor electronic device lists, and establishes on this basis Start the network topology diagram.

In an embodiment, the broadcasting the first request includes:

broadcasting said first request upon receipt of a second voice command; and/or,

broadcasting the first request if the first request is received; wherein,

The second voice instruction is used to instruct to acquire the network topology map.

Here, the second voice instruction is used to instruct electronic device A to obtain the network topology map, and the electronic device used to initiate the creation process of the network topology map initiates the corresponding creation process after receiving the first voice instruction. In some cases, the second voice command may also be the first voice command. In other words, when the wake-up device receives the first voice command for instructing the target device to perform an operation, it first broadcasts the first request to Acquire the network topology map, and then determine the first transmission path corresponding to the first voice instruction based on the network topology map.

In the process of sending the first request layer by layer, other electronic devices start the process of collecting the neighbor electronic device list after receiving the first request broadcast by the neighbor electronic device.

In practical applications, as shown in the schematic diagram of information collection in FIG. 3 , device A broadcasts a first request to two neighboring electronic devices B and C in order to wake up the device after receiving the first voice command. The device B of the neighboring electronic device B broadcasts the first request to the neighboring electronic device D upon receiving the first request. The device C of the neighboring electronic device C broadcasts the first request to the neighboring electronic device D upon receiving the first request. The device D of the neighboring electronic device D reports the information D of the neighboring electronic device of the device D to the two neighboring electronic devices B and C based on the received two first requests of the device B and the device C: [B, C], characterized The neighbor electronic devices of device D are device B and device C. Based on the received first request from device A, device B reports to neighbor electronic device A the information B: [A, D] of device B's neighbor electronic devices and the received neighbor electronic device list D: [B, C].

Device A and device B deployed with voice assistants are provided with a coordinated instruction transmission module and a coordinated wake-up module. The coordinated wake-up of device A When the module receives the wake-up command, the wake-up device A receives the voice command through the cooperative command transmission module, and realizes the voice command transmission between the near-field communication devices through the networking among multiple electronic devices, specifically including, carrying the voice command through the message . The coordinated command transmission module is responsible for the coordinated command transmission between near-field devices, which solves the problems of the networking between multiple devices, the transmission of voice commands needs a small delay, and the transmission nodes are as few as possible during the coordinated command transmission.

Taking the cross-device execution of mobile phones, watches, and TVs as a scenario, the present application will be further described in detail in combination with application embodiments. As an application embodiment of the present application, the method of the application embodiment of the present application is implemented by the cooperative instruction transmission module.

As an application embodiment of the present application, taking the implementation flow diagram 1 of the information transmission method shown in FIG. 9 as an example, the following steps are included:

Step 901: Information collection.

In the event that the device detects voice input, the information collection process begins. Information collection realizes networking among multiple electronic devices in a heterogeneous network by discovering neighboring electronic devices.

A voice command is received, a network topology graph characterized as a network topology snapshot is generated based on information collection results, and a directed graph is generated based on the network topology snapshot.

In the embodiment of the present application, combined with the schematic diagram of information collection shown in FIG. 3 , the initiator device A that receives the voice command broadcasts a request message to all neighboring electronic devices B and C through each communication capability it has, and the request message uses To request the electronic device that has received the first request information to collect the neighbor electronic device list and broadcast the first request information, after receiving the request message, device B and device C, taking device B as an example, determine its neighbor electronic device list B : [A, D], and forward the request message to its neighbor electronic device D respectively, device B receives the neighbor electronic device list D: [B, C] sent by device D based on the forwarded request message, and sends its The neighbor electronic device list B: [A, D] and the received neighbor electronic device list D: [B, C] are sent to the initiator device.

Step 902: Command transmission path.

The shortest transmission path from the wake-up device to the target device is calculated by a shortest path algorithm, such as the Floyd algorithm, as the first transmission path. When sending a request message carrying the first transmission path representing the shortest transmission path, perform message addressing based on the first transmission path in the request message, determine the next-hop electronic device, and send a request to the determined electronic device information.

When sending a request message or a response message, perform message addressing based on the first transmission path carried in the message, determine a next-hop electronic device, and send the request message or response message to the determined electronic device. Here, message routing includes request message addressing and response message addressing. The addressing of the request message indicates that the device queries the successor node of the node where the device ID is located from front to back through the routing module in the first transmission path, uses the successor node as the next hop node, and sends the request message correspondingly. The response message addressing means that the device queries the successor node of the node where the device ID is located from the back to the front through the routing module in the first transmission path, and uses the successor node as the next hop node to send the request message correspondingly. When each electronic device receives the message, if the target device ID in the message is the same as its own device ID, it means that the message is delivered to the target device ID; if the target device ID in the message is not the same as its own device ID, Routing and forwarding is then performed according to the first transmission path.

In the embodiment of the present application, referring to the schematic diagram of path transmission shown in FIG. 11, the initiator device A determines the target device D based on the received voice command, and determines the first transmission path [A, B based on the target device D and the directed graph. , D]. Based on the target device ID, the initiator device ID (source device ID), the transaction ID, the first transmission path [A, B, D] and the content of the voice command, the request message is generated according to the format example of the above message. Here, the transaction ID can use the snowflake algorithm SnowFlake to generate a unique identifier, the first transmission path can be characterized as a list of device IDs [device ID ₁ , device ID ₂ , ..., device ID _X ], and device ID ₁ is the initiator device ID, device ID _X is the target device ID.

The initiating device A sends a request message, and based on the first transmission path [A, B, D] in the request message, finds that the successor node of the node where the device ID is located is device B, and uses device B as the next hop node. Send a request message to device B. After receiving the request message, device B judges the conclusion that the request message needs to be forwarded based on the target device ID, and then determines the ID of the device by forward searching the first transmission path [A, B, D]. The successor node finds device D as the next hop node. Device D receives the message, finds out through the target device that it is a request message sent to the device, and executes the operation corresponding to the request message, with device A as the target device, device D as the source device, the transaction ID in the request message and the first transmission path , generate a response message following the format example of the message above. Device D sends a response message. Based on the first transmission path [A, B, D] in the response message, it reversely finds that the successor node of the node where the device ID is located is device B, and uses device B as the next hop node. Send a request message to device B. After receiving the request message, device B judges the conclusion that the request message needs to be forwarded based on the target device ID, and then finds the first transmission path [A, B, D] in reverse to determine the ID of the device. The successor node finds device A as the next hop node. Device A receives the message, and discovers through the target device that it is a response message sent to the device. At this point, the interaction between a request message and a response message is completed.

In the application embodiment of this application, in order to solve the real-time and accuracy problems of voice assistant routing among multiple devices in the near field and the execution of cross-device voice commands, a network topology snapshot is constructed by broadcasting during the communication capability collection stage, and Generate a directed graph to obtain a dynamic network topology and realize the shortest transmission path. And by using the way of transmission path addressing, the routing problem of the instruction is solved.

The forwarding electronic device can realize the routing of voice commands between the source device and the target device based on the routing addressing carried in the first message, and at least achieve the following effects: collect node communication capabilities through broadcasting, and determine a snapshot of the network topology , corresponding to the way of generating a directed graph, to solve the networking problem among multiple electronic devices. And, based on the first transmission path in the first message, determine the next-hop electronic device, and send the first message to the determined electronic device, so that the two-way transmission path between the wake-up device and the target device can be realized, Thereby reducing the delay in the execution of voice commands across devices. At the same time, based on the planned shortest transmission path from the source device to the target device, the number of electronic devices involved in information transmission can be reduced, and the reliability of the transmission path can be improved.

In this way, in the actual application of intelligent voice multi-terminal fusion projects, in the face of multi-device scenarios composed of mobile phones, watches, TVs, etc., in a small-scale network (5-6 devices), it is possible to achieve hundreds of milliseconds Voice commands are delivered with end-to-end delay. Meet the real-time and accuracy requirements of voice command execution in the smart voice usage scenario between multiple near-field devices in the home.
