Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

Please refer to FIG. 1 , which is a flow chart of a voice control method for home equipment provided by an embodiment of the present invention. This method is applied to wearable devices and can include:

Step 101: Obtain wake-up broadcast data based on the wake-up word data collected by the microphone; wherein the microphone is set in the wearable device.

Specifically, the wearable device in this embodiment can be a device with Bluetooth (BT) function that the user can wear, such as a wireless headset, a head-mounted display device, a watch device, a bracelet device, etc. The specific device type of the wearable device in this embodiment can be set by the designer according to practical scenarios and user needs. For example, the wearable device can be a Bluetooth headset, such as a TWS (True Wireless Stereo) headset; Wearable devices can also be specifically head-mounted display devices, such as AR (Augmented Reality, augmented reality) glasses and VR (Virtual Reality, virtual reality) glasses; wearable devices can also be other devices such as watch devices and bracelet devices. Wearable devices, as long as the wearable devices can have Bluetooth functions, this embodiment does not place any restrictions on this. The microphone in this embodiment may be a microphone provided in a wearable device for collecting voice data, such as the main Mic (microphone) in Figure 2 .

It can be understood that the wake word data in this step can be the field data corresponding to the wake word collected by the microphone, that is, the voice data of the wake word field. The wake-up broadcast data in this step can be the BLE broadcast data corresponding to the wake-up word data that the wearable device needs to send through BLE (Bluetooth Low Energy) broadcast.

Specifically, in this step, the specific way for the processor in the wearable device to obtain the wake-up broadcast data based on the wake-up word data collected by the microphone can be set by the designer according to practical scenarios and user needs. For example, the processor can obtain the wake-up broadcast data based on the wake-up word data. data and wake-up identifier to generate wake-up broadcast data, so that the home device can determine the wake-up broadcast data based on the wake-up identifier in the received BLE broadcast data, and perform the corresponding response process, such as obtaining the relative position information of the home device and wake-up word ratio Peer-to-peer, that is, the wake-up broadcast data in this embodiment may include wake-up word data and wake-up identification. The wake-up broadcast data in this embodiment may not include wake-up word data. For example, the processor may generate a wake-up identification corresponding to the wake-up word data based on the wake-up word data in the voice data collected by the microphone; generate wake-up broadcast data according to the wake-up identification to Enables home devices to find the wake-up word data corresponding to the wake-up sign (i.e., device wake-up word data) from the voice data collected by its own microphone based on the wake-up sign in the received BLE broadcast data, thereby using its own device wake-up word data. Wake word comparison.

Correspondingly, in this embodiment, this step may also include identifying wake word data in the voice data collected by the microphone. The specific way for the processor to identify the wake word data in the voice data collected by the microphone can be set by the designer according to practical scenarios and user needs. For example, the processor obtains the voice data collected by the microphone; detects whether there is a wake word in the voice data; If yes, the field data corresponding to the wake-up word in the voice data is determined as the wake-up word data; if not, the process can be ended or return to the step of obtaining the voice data collected by the microphone; that is to say, the processor can process the voice data collected by the microphone. The data is subjected to wake word detection, and the voice data (ie, field data) corresponding to the detected wake word field is determined as wake word data. The processor can also directly use all or part of the voice data as wake word data, and use the wake word comparison information in the response data returned by the home device to determine whether there is a wake word in the wake word data; for example, because the user is speaking During control, the wake-up word will be spoken first and then the control instruction. The processor can use the voice data within the preset time in each detected voice data as the wake-up word data.

Furthermore, in this embodiment, before this step, it may also include detecting whether the wearable device is in a wearing state; if so, obtain the wake-up broadcast data based on the wake-up word data collected by the microphone; if not, the process may be ended directly or return to detection. Steps to determine whether the wearable device is in a wearing state; to ensure the accuracy of voice control of home devices through wear detection of the wearable device.

Step 102: Perform BLE broadcast of the wake-up broadcast data, and receive response data returned by the home device connected to the wearable device via Bluetooth; where the response data includes relative position information of the home device or relative position information of the home device and wake-up word comparison information.

It can be understood that the home device in this step can be connected to the wearable device via Bluetooth, that is, the wearable device can be connected to multiple home devices via Bluetooth. The response data in this step can be the data sent to the wearable device after the home device receives the wake-up broadcast data broadcast by BLE, such as the ACK (confirmation character) in Figure 2.

Specifically, the specific content of the response data returned by each home device to the wearable device in this step can be set by the designer according to practical scenarios and user needs. For example, the response data can include relative position information of the home device, that is, the relative position of the home device. Information related to the position of the wearable device; for example, the relative position information of the home device may include the reception time information (such as a timestamp) of the wake-up broadcast data, which is used to represent the distance of the home device relative to the wearable device; the relative position information of the home device may also be Including the Received Signal Strength Indication (RSSI) value, which is used to characterize the distance and angle of home devices relative to wearable devices. The response data may also include wake word comparison information, such as the result information obtained by comparing the wake word data of the home device or the device wake word data and the preset wake word. For example, the wake word comparison information may be the device wake word data stored by the home device. The result information obtained after the preset wake-up word.

It should be noted that in this embodiment, after the wearable device broadcasts the wake-up broadcast data via BLE, each home device can generate response data based on the scanned wake-up broadcast data broadcast by BLE and send it to the wearable device.

Specifically, the specific way in which each home device can generate response data based on the scanned wake-up broadcast data of BLE broadcast can be set by the designer. For example, when the wake-up broadcast data includes a wake-up logo, the home device can scan the BLE broadcast. After receiving the wake-up broadcast data containing the wake-up logo, record the timestamp of scanning the wake-up broadcast data (ie, receiving time information); compare the wake-up word data in the wake-up broadcast data or the device wake-up word data corresponding to the wake-up logo with the preset wake-up word. Compare and obtain the wake word comparison information, such as binary comparison between the device wake word data and the preset wake word (that is, the standard forward wake word) to obtain the difference value; obtain the RSSI value of the current Bluetooth connection with the wearable device; according to the timestamp, The wake word compares the information with the RSSI value to generate response data. As shown in Figure 2, once the smart home device (i.e. home device) scans the wake-up broadcast data of this BLE broadcast, it can first record the timestamp at this time (i.e., receive time information); then the smart home will recognize the Mic FIFO (First-in, first-out queue) The memory section where the device wake-up word data corresponding to the wake-up identification in the cache is located. The data is then extracted for binary sampling conversion. At the same time, in the initial state of the smart home, the user-defined wake-up word will be stored in the memory. The standard binary data (i.e., the preset wake word), the smart home will perform a binary comparison between the two data, and obtain a positive indicator (i.e., the difference value) of the wake word in the Mic-enrolled environment and the standard wake word as a judgment Whether the user speaks one of the values of the voice command toward the device; at the same time, the smart home will also obtain the RSSI value in the current BT connection based on the RSSI protocol of the BT physical layer; finally, the smart home device will form these three indicators into ACK data The frame is sent to the TWS headset worn by the user in real time through the SPP (Serial Port Profile, Bluetooth protocol stack serial port protocol) channel in BT.

Correspondingly, in this embodiment, the specific way in which the wearable device receives the response data returned by the home device connected to the wearable device via Bluetooth, that is, the specific way in which the home device sends response data to the wearable device, can be set by the designer. For example, each home device can send response data to the wearable device through BLE broadcast, that is, the wearable device can scan through BLE and receive the response data returned by the home device; in order to improve the efficiency of receiving response data, each home device can also use the wearable device to The Bluetooth multi-point connection communication channel sends response data to the wearable device, that is, the wearable device can receive the response data sent by each home device through the Bluetooth multi-point connection communication channel (SPP channel in Figure 2).

Furthermore, in this embodiment, each home device can perform clock calibration; as shown in Figure 2, each home device can perform clock calibration through the network; the wearable device can also control the home device before performing BLE broadcast of the wake-up broadcast data. Perform clock calibration.

Step 103: Identify the target home device among the home devices based on the response data.

It can be understood that the target home device in this step can be a home device that needs to respond to wake word data and perform corresponding voice control operations; for example, the target home device can be any home device that is connected to the wearable device via Bluetooth. . In this step, the wearable device can identify the target home device among the home devices based on the response data returned by each home device, so as to use the target home device to complete the corresponding voice control operation.

Specifically, in this step, the specific way for the processor to identify the target home device in the home device based on the response data can be set by the designer according to the practical scenario and user needs. For example, the response data includes reception time information and received signal strength indication. When comparing information with value and wake word, the processor can determine the target home device in the home device based on the corresponding reception time information, received signal strength indication value and wake word comparison information of each home device; where, the target home device is Any home device. For example, when the wake word comparison information is wake word data or the difference value (such as a positive indicator) between the device wake word data and the preset wake word, the processor can pass D=

(α·V, β·R, δ·T, Q), calculate the target home device; among them, Q represents the device queue of the home device, T represents the corresponding reception time information of each home device, and δ represents its weight (i.e. Time weight); R represents the corresponding RSSI value of each home device, β represents its weight (i.e., signal weight); V represents the wake word comparison information corresponding to each home device, and α represents its weight (i.e., comparison weight);

Represents a specific weighted calculation method. Its main function is to calculate the weighted calculation value based on each weight, map the results to each device, and then output the final target home device D. For example, the processor can calculate the corresponding weighted calculation value of each home device based on the reception time difference, received signal strength indication value and wake word comparison information of each home device; where each reception time difference is the sending time information of the wake broadcast data and The difference between the reception time information of the corresponding home devices; the weighted calculation value is the reception time difference, received signal strength indication value and wake word comparison information of each home device and the corresponding preset weight (such as time weight, signal weight and comparison weight) ); determine the home equipment corresponding to the target weighted calculation value as the target home equipment; wherein, the target weighted calculation value is the weighted calculation value with the largest value among the calculated weighted calculation values.

Step 104: Control the target home device to perform corresponding voice control operations according to the control voice data corresponding to the wake word data collected by the microphone.

It can be understood that in this embodiment, the processor of the wearable device can control the target home device to perform corresponding voice control operations based on the control voice data corresponding to the wake-up word data collected by the microphone, so as to utilize the wearable device to organize the home devices. Management and information interaction, realizing voice control of home equipment, reducing the control links of intermediate devices (such as mobile phones), and improving the efficiency and naturalness of human-computer interaction in smart homes.

Specifically, the control voice data in this step can be the control voice data after the wake-up word data in the voice data collected by the microphone; if the user wants to control a certain home device, he can directly issue a voice command to the home device. The voice command It mainly consists of two parts. The first part is the wake-up word, and the second part is the specific voice control command, such as: "Hi, turn on the phone." In this example, "Hi" is the wake-up word. The user can also define it by himself in actual application. "Power on" is a specific voice control command; after the wearable device (such as TWS headset) worn by the user recognizes the wake-up word, it can automatically collect all voice commands, that is, wake-up word data and control voice data, thereby determining the target home device , use the target home device to complete the voice control instructions corresponding to the control voice data.

Correspondingly, the specific selection of control voice data in this step can be set by the designer according to the usage scenario and user needs. For example, the control voice data can be the first piece of voice data after the wake-up word data in the voice data collected by the microphone; The control voice data can also be the voice data within a preset time period after the wake-up word data in the voice data collected by the microphone. That is, after the user speaks the wake-up word, he can say multiple voice control instructions within the preset time period, thereby multiple times. Control target home devices.

Specifically, in this step, the specific way for the processor to control the target home device to perform the corresponding voice control operation based on the control voice data corresponding to the wake-up word data collected by the microphone can be set by the designer according to the practical scenario and user needs, such as The processor obtains voice control instructions based on the control voice data in the voice data collected by the microphone; where the control voice data is the voice data within a preset time period after the wake word data; sends the voice control instructions to the target home device to control the target The home device performs the voice control operation corresponding to the voice control command. For example, the processor can send the voice control command to the target home device through a Bluetooth connection link, such as the BT A2DP (Bluetooth Audio Transfer Model Protocol) link in Figure 2. The target home device enables the target home device to perform voice control operations corresponding to the voice control instructions; the processor can also directly send the control voice data corresponding to the wake word data to the target home device to control, parse and execute the voice corresponding to the control voice data. For control operations, for example, the processor can send wake word data and corresponding control voice data to the target home device. This embodiment does not impose any restrictions on this.

Correspondingly, the specific content of the above voice control instructions can be set by the designer according to the usage scenario and user needs. For example, the voice control instructions can include control voice data so that the target home equipment can use wearable devices to collect more accurate information. The voice data is used to control voice recognition and function execution to improve the accuracy of voice control of home devices; the voice control instructions can also include control identifiers corresponding to the control voice data, so that the target home device can use the control identifiers to collect from its own microphone Extract the corresponding control voice data (i.e., device control voice data) from the stored voice data, and use the device control voice data collected and stored by itself to perform control voice recognition and function execution, thereby reducing the communication between the wearable device and the target home device. The amount of data increases the communication speed of voice control instructions. This embodiment does not impose any restrictions on this.
