[0038] Figure 1 It is a flowchart of a cross-device wake-up method provided by an embodiment of the present invention;

[0039] Figure 2 It is a structural diagram of a cross-device wake-up apparatus provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figure 1 As shown, an embodiment of the present invention provides a cross-device wake-up method, comprising: when multiple devices in a local area network obtain a wake-up audio signal within a preset time,

[0042] Step S1: determining the multiple devices as devices to be awakened;

[0043] Specifically, the multiple devices in the local area network include at least two types of devices.

[0044] For example: smart refrigerators, smart air conditioners, smart washing machines and smart speakers, etc.

[0045] When a user needs to use a device, the same voice trigger is used, and the device in the local area network obtains a wake-up audio signal containing the requirement through its own microphone. The wake-up audio signal may include information such as: turn on, turn off, or standby.

[0046] For example: the user says the wake-up word "Xiaoyi Xiaoyi", and then the wake-up word is received by the device in the local area network.

[0047] In the embodiments of the present invention, a user can wake up a target device across devices by using a wake-up word, which saves time and effort and makes the operation convenient and efficient.

[0048] Step S2: Based on the wake-up audio signal, each device to be awakened obtains a determination parameter and receives determination parameters of other devices to be awakened;

[0049] Specifically, based on the wake-up audio signal, each device to be awakened obtains a determination parameter and receives determination parameters of other devices to be awakened, including:

[0050] For each device to be awakened, the device to be awakened generates a determination parameter of the device to be awakened based on the wake-up audio signal;

[0051] For each device to be awakened, the device to be awakened sends the determination parameters of the device to be awakened to other devices to be awakened, and receives the determination parameters of other devices to be awakened sent by other devices to be awakened.

[0052] Furthermore, the determination parameters include:

[0053] Comprehensive energy value, trigger time and wake-up angle, as well as identification parameters.

[0054] The comprehensive energy value is calculated by the following formula:

[0055] Comprehensive energy value = original energy value × correlation coefficient. The larger the comprehensive energy value, the closer the device is to the user. Therefore, the device to be awakened with the largest comprehensive energy value in the local area network is the target device.

[0056] In actual application scenarios, in addition to differences in device types and / or models, multiple devices in a local area network may also have differences in the number of microphones (for example, 6 or 4) and arrangement. These differences will affect the values ​​of parameters calculated by the algorithm library. The algorithm library uses the original raw data, adds conditions such as the number of microphones and the arrangement of microphones on the current device, and outputs an energy value associated with the current device and the device used as a benchmark.

[0057] Because the number and arrangement of microphones in different devices may be different, a standard device is selected in advance. The standard device can be a device in the local area network or a pre-set specific device. The original energy value of the device of the standard device is used as the benchmark energy value (for example, the original energy value of the 6-microphone device is used as the benchmark energy value), and the original energy values ​​of other devices are evaluated and calculated based on this benchmark energy value; in the evaluation calculation, the correlation coefficient between other devices and the standard device (for example, the 6-microphone device) is generated to overcome the error caused by the difference in structure between other devices and the standard device.

[0058] For example, taking 6 microphone devices as the standard device, first calculate the original energy value of each device that receives the wake-up audio signal, and then calculate the correlation coefficient of each device based on the specific number and arrangement of microphones of each device (generally, when the specific structure of each device is determined, the correlation coefficient is a fixed value to facilitate the calculation of the comprehensive energy value);

[0059] The original energy value of the device is multiplied by the correlation coefficient of the device to obtain the energy value of the device compared with the reference device, that is, the "comprehensive energy value" of the device.

[0060] Therefore, based on the original energy value and the correlation coefficient, the comprehensive energy value of each device in the LAN can be obtained.

[0061] For example, the comprehensive energy value of the device to be awakened is 10. Based on the local area network, the device to be awakened obtains the comprehensive energy values ​​of all devices included in other devices. The algorithm library of the device to be awakened compares its own comprehensive energy value with all other comprehensive energy values ​​obtained. For example, the comprehensive energy value of the device to be awakened ranges from 2 to 8. After comparison, the algorithm library of the device to be awakened finds that the comprehensive energy value of the device to be awakened is the largest. Therefore, the device to be awakened determines itself as the target device.

[0062] If the comprehensive energy values ​​of the devices included in the device to be awakened range from 2 to 12, the algorithm library of the device to be awakened can be compared to find that the comprehensive energy value of the device to be awakened is the largest. Therefore, the device to be awakened determines other devices as target devices.

[0063] In an embodiment of the present invention, the distance between a device and a user in a local area network is judged based on a comprehensive energy value. The larger the comprehensive energy value, the closer the distance between the corresponding device and the user is. The comprehensive energy value combines the original energy value of the device and the correlation coefficient, wherein the correlation coefficient overcomes the problem that different types of devices have different numbers and arrangements of microphones. Therefore, the method of determining the target device through the comprehensive energy value can realize accurate wake-up of the target device across devices, thereby improving the user experience.

[0064] Step S3: Each device to be awakened performs data analysis according to all the determination parameters to determine the target device;

[0065] Each device to be awakened performs data analysis according to all the determination parameters to determine the target device, including: for each device to be awakened, the device compares all the comprehensive energy values ​​to obtain a comprehensive energy value comparison result;

[0066] If the number of devices corresponding to the comprehensive energy value comparison result does not exceed the preset number, the device to be awakened determines the device to be awakened corresponding to the comprehensive energy value comparison result as the target device.

[0067] The preset number is the maximum number of devices that can be woken up simultaneously, preferably 1.

[0068] An optional embodiment of the present invention further includes:

[0069] If the number of devices corresponding to the comprehensive energy value comparison result exceeds the preset number, the device to be awakened compares all the trigger times to obtain a trigger time comparison result;

[0070] Further, if the number of devices corresponding to the trigger time comparison result does not exceed the preset number, the device to be awakened determines the device to be awakened corresponding to the trigger time comparison result as the target device.

[0071] Further, if the number of devices corresponding to the trigger time comparison result exceeds the preset number, the device to be awakened compares the wake-up angles to obtain a wake-up angle comparison result;

[0072] Further, if the number of devices corresponding to the wake-up angle comparison result does not exceed the preset number, the device to be awakened determines the device to be awakened corresponding to the wake-up angle comparison result as the target device.

[0073] Specifically, when multiple devices obtain the wake-up audio signal, they will record and store the trigger time;

[0074] When multiple devices obtain the wake-up audio signal, they will also record and store the wake-up angle;

[0075] In addition, according to actual needs, other information can be preset as judgment parameters to more accurately and quickly determine the target device. For example, it can also include identification parameters for determining the identity of the target device, so as to determine the target device based on the comparison results.

[0076] In an actual application scenario, if the number of devices corresponding to the wake-up angle comparison result exceeds the preset number, the devices in the local area network go into sleep mode, do not respond to the wake-up audio signal, and wait for a new wake-up audio signal.

[0077] After obtaining their own comprehensive energy values, multiple devices use the comprehensive energy values, trigger time and wake-up angle as judgment parameters and send them to the local area network in the form of LAN broadcast; multiple devices receive the judgment parameters in the local area network and filter their own judgment parameters based on the identification parameters.

[0078] When the target device cannot be determined according to the comprehensive energy value, the target device is determined according to the trigger time. When the target device cannot be determined according to the trigger time, the target device is determined according to the wake-up angle.

[0079] Generally, the earlier the trigger time corresponding to a device is, the closer the user is to the device.

[0080] For example, when the comprehensive energy values ​​of multiple devices are the same, or the difference between the comprehensive energy values ​​of multiple devices is less than a threshold, it indicates that the target device cannot be determined based on the comprehensive energy value. Therefore, multiple devices compare all the acquired trigger times and take the device with the earliest trigger time as the target device.

[0081] When the triggering time of multiple devices is the same, or the difference between the triggering times of multiple devices is less than a threshold, it indicates that the target device cannot be determined based on the triggering time. Therefore, multiple devices compare all the acquired wake-up angles and determine the target device based on the comparison results of the wake-up angles according to a preset judgment method. For example, the device with the wake-up angle closest to 90 degrees is the target device.

[0082] Step S4: the target device performs self-wake-up in response to the wake-up audio signal.

[0083] The target device performs self-wake-up in response to the wake-up audio signal, including:

[0084] For each device to be awakened, the device to be awakened compares the identification parameter corresponding to the target device with the identification parameter corresponding to the device to be awakened;

[0085] If the identification parameter corresponding to the target device is consistent with the identification parameter corresponding to the device to be awakened, the device to be awakened performs self-awakening in response to the wake-up audio signal.

[0086] After the target device is determined, the identification parameters of the target device are compared with the parameters of the device that determines the target device. If they are consistent, the device that determines the target device is the target device. At this time, the target device is awakened based on the wake-up audio signal, responds to the user's needs and performs a series of subsequent interactions with the user.

[0087] After the real target device is determined, the target device will receive a feedback signal, and then the target device will respond according to the wake-up audio signal. At this time, the target device is truly awakened and interacts with the user in real time based on the user's subsequent output audio signal.

[0088] In actual application scenarios, the devices in the preset local area network may include smart refrigerators, smart air conditioners, smart washing machines, and smart speakers;

[0089] When a user wants to use the smart speaker, the user says a wake-up word, such as "turn on".

[0090] Smart refrigerators, smart air conditioners, smart washing machines and smart speakers all obtain wake-up audio signals. The algorithm libraries of smart refrigerators, smart air conditioners, smart washing machines and smart speakers first calculate their respective original energy values ​​based on the wake-up audio signals, then obtain the correlation coefficient, and finally obtain the product of the original energy value and the correlation coefficient to determine the comprehensive energy value.

[0091] The smart refrigerator, smart air conditioner, smart washing machine and smart speaker respectively send their comprehensive energy values ​​to the local area network in the form of local area network broadcast.

[0092] Smart refrigerators, smart air conditioners, smart washing machines and smart speakers will respectively compare their own comprehensive energy values ​​with the comprehensive energy values ​​of other devices and obtain the comparison results.

[0093] Based on the comparison results, the smart refrigerator, smart air conditioner, smart washing machine and smart speaker all determined the maximum value of the comprehensive energy value. By identifying the identification parameters they carried, the target device was determined to be a smart speaker.

[0094] Among the smart refrigerators, smart air conditioners, smart washing machines and smart speakers, the ones that are consistent with the target devices are smart speakers. Therefore, the smart speakers respond to the wake-up audio signal. At this time, the smart speakers are truly awakened and perform subsequent interactions with the user based on the user's needs.
