Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

To facilitate understanding of any embodiment of the present disclosure, first, an intelligent voice wake-up scenario in an intelligent home is taken as an example for explanation.

Referring to fig. 1, in the smart voice wake-up scenario of the smart home, the electronic device with a voice recognition function is provided, which includes: a television 01, a sound box 02 and a sweeping robot 03. Here, the above-mentioned 3 electronic devices are all disposed in one space, for example, a living room. The user can wake up the electronic equipment with the voice recognition function by sending out the wake-up voice. For example, the user may wake up the electronic device having a voice recognition function by a wake-up voice calling the wake-up word "xxx". Here, waking up the electronic device having the voice recognition function may be activating a voice signal recognition function of the electronic device in response to a voice instruction. Here, the voice signal recognition function in response to the voice instruction may be a function of executing an action indicated by the voice instruction after receiving the voice instruction. For example, the voice signal recognition function of the television set in response to the voice command may be a function of performing "zapping" after receiving the voice command of "zapping".

In one embodiment, when the volume of the wake-up voice received by the electronic device with voice recognition function is greater than the set volume threshold, the electronic device with voice recognition function starts the voice signal recognition function responding to the voice command. And when the volume of the awakening voice received by the electronic equipment with the voice recognition function is smaller than a set volume threshold, the electronic equipment with the voice recognition function does not start the voice signal recognition function responding to the voice instruction.

In one embodiment, the user needs to turn on the tv 01 in the living room, the user calls the "play" wake-up word, and after receiving the "play" wake-up voice, the tv 01, the speaker 02 and the floor sweeping robot 03 in the living room determine whether the volume of the wake-up voice is greater than the set volume threshold. In one embodiment, if the volume of the wake-up voice received by the television 01 is greater than the volume threshold set by the television 01, and the volumes of the wake-up voices received by the sound box 02 and the floor-sweeping robot 03 are less than the respective set volume thresholds, the television 01 will start the voice signal recognition function responding to the voice instruction, and the sound box 02 and the floor-sweeping robot 03 will not start the voice signal recognition function responding to the voice instruction. After the voice signal recognition function in response to the voice command is turned on, if the television set 01 receives a voice command of "zapping", the operation of "zapping" is executed. Thereby realizing voice control of the television set 01. It should be noted that, after the voice signal recognition function of the television 01 responding to the voice instruction is turned on, if the volume of the voice signal received by the television 01 and related to the "voice instruction" is less than the volume threshold set by the television 01, the television 01 will not execute the operation indicated by the voice instruction. For example, when the voice signal of the voice instruction "zap" is smaller than the volume threshold set by the television set 01, even if the television set 01 receives the voice signal instruction of "zap", the operation of "zapping" is not performed. Here, the voice signal of the voice instruction may be a voice signal generated when the user calls out a keyword for issuing a voice instruction, for example, a voice signal generated when the user calls out "zap", "tune", or "rotate" to issue a voice instruction.

Here, since the voice signal recognition function of the sound box 02 and the floor sweeping robot 03 is not turned on in response to the instruction, the operation instructed by the voice instruction is not performed even if the voice instruction is received. For example, the sound box 02 does not perform the tuning operation indicated by the voice instruction of "tuning"; the sweeping robot 03 does not perform the rotation operation indicated by the voice instruction of "rotation".

Here, when the volumes of the wake-up voices received by the television 01, the speaker 02 and the floor-sweeping robot 03 are all greater than the respective set volume thresholds, the voice signal recognition functions of the television 01, the speaker 02 and the floor-sweeping robot 03 responding to the voice command may be simultaneously activated.

As shown in fig. 2, an embodiment of the present disclosure provides a flowchart of a method for waking up a device, which is applied to an electronic device as shown in fig. 1, where the method includes the following steps:

step 21, detecting a wake-up voice;

step 22, responding to the detected awakening voice, and starting a Bluetooth scanning function;

step 23, scanning a broadcast message sent based on the detected awakening voice based on the Bluetooth scanning function; wherein, the broadcast message at least carries a response priority;

and 24, determining whether the electronic equipment starts a voice signal recognition function responding to the voice command or not based on the response priority carried by the broadcast message and the response priority of the electronic equipment.

In one embodiment, the method for waking up the device is applied to the electronic device. The electronic device may be various types of mobile devices or stationary devices. For example, the electronic device may be a smart wearable terminal, a smart home terminal, an industrial sensing device, a medical device, and/or the like.

In one embodiment, the wake-up signal may be a voice signal emitted by a user for controlling the electronic device. Here, the wake-up signal may be a voice signal having a preset characteristic. For example, the wake-up signal may be a voice signal containing the keyword "xxx". Here, the preset feature of the wake-up signal may be stored in the electronic device, and when the electronic device receives the voice signal, the voice signal is compared with a voice signal corresponding to the preset feature stored in the electronic device to determine whether the voice signal is the wake-up signal. That is, when the electronic device receives a voice signal, it first determines whether the voice signal is a voice signal conforming to a predetermined characteristic, and only when the voice signal is a voice signal conforming to the predetermined characteristic, a response operation is performed with respect to the voice signal. Here, the response operation includes determining whether or not the volume of the voice signal is larger than a set volume threshold value, and the like.

In one embodiment, the operating states of the electronic device include a sleep state and an active state. When the electronic device is in a sleep state, the function of receiving the voice signal is turned on, and the functions other than the function of receiving the voice signal are turned off. For example, a function of receiving a voice signal is turned on, and a bluetooth scan function, a broadcast function, and the like are turned off. The electronic device is only woken up by the wake-up voice with the preset characteristics, and the functions except the function of receiving the voice signal can be turned on. At this time, the electronic device enters an operating state, and the electronic device entering the operating state may respond to an operation instructed by the execution of the voice instruction. Therefore, the electric energy of the electronic equipment is saved, and the standby time of the electronic equipment is prolonged.

In one embodiment, the wake-up tone may be detected periodically. Referring to fig. 3, the period can be divided into a sleep period and a running period. When the electronic equipment is in the dormant period, the electronic equipment stops detecting the awakening voice; and when the electronic equipment is in the operation period, the electronic equipment detects the awakening voice. Here, the ratio of the duration of the sleep period to the duration of the operation period may be determined according to the frequency of waking up the electronic device. When the frequency of the electronic device being awakened is greater than the frequency threshold, the time length ratio of the time length of the sleep period to the time length of the operation period may be set to be less than the time length ratio threshold. When the frequency of waking up the electronic device is less than the frequency threshold, the time length ratio of the time length of the sleep period to the time length of the operation period may be set to be greater than the time length ratio threshold. Therefore, the electronic equipment can be ensured to work in a low-energy consumption state, and the electric energy is saved.

In one embodiment, the wake-up signal is determined to be detected in response to the electronic device receiving a voice signal and the voice signal having a predetermined characteristic. In one embodiment, the voice signal having the predetermined characteristic may be a voice signal generated by the user calling out a keyword of "xxx" and/or a volume of the voice signal is greater than a set volume threshold. For example, if the voice signal received by the television is a voice signal generated by calling out the keyword "play" by the user and the volume of the voice signal is greater than the volume threshold a value set by the television, the electronic device determines that the wake-up signal is detected.

In one embodiment, the bluetooth scan function is enabled when the electronic device detects a voice signal having a predetermined characteristic. When the electronic device does not detect a voice signal with a predetermined characteristic, the bluetooth scanning function is not turned on. Here, the bluetooth scan function of the electronic device is a function of scanning a signal based on a bluetooth low energy protocol. Here, the bluetooth scanning function may be to scan a voice signal carrying a voice command issued by a user. Here, the voice instruction may be a control instruction instructing the electronic device to perform a related operation. For example, the voice instruction may be a "zapping" instruction instructing the television set to perform an operation of "zapping"; the voice instruction can also be a 'rotation' instruction for instructing the sweeping robot, and the 'rotation' instruction is used for instructing the sweeping robot to execute the 'rotation' operation; the voice instruction may also be an "up volume" instruction that instructs the loudspeaker to perform an "up volume" operation.

In one embodiment, the bluetooth scanning function is periodically performed after being turned on. Referring again to fig. 3, the cycle may be divided into a sleep period and a run period. When the electronic equipment is in the dormant period, the electronic equipment stops scanning operation; when the electronic equipment is in the operation period, the electronic equipment executes scanning operation. Here, the ratio of the duration of the sleep period to the duration of the operation period may be determined according to the frequency of receiving voice commands of the electronic device. When the frequency of the electronic device receiving the voice command is greater than the frequency threshold, the time length ratio of the duration of the sleep period to the duration of the operation period may be set to be less than the time length ratio threshold. When the frequency of the electronic device receiving the voice command is less than the frequency threshold, the time length ratio of the duration of the sleep period to the duration of the operation period may be set to be greater than the time length ratio threshold. Therefore, the electronic equipment can be ensured to work in a low-energy consumption state, and the electric energy is saved.

In one embodiment, the broadcast message may be transmitted by other devices in the same space than the electronic device. For example, taking fig. 1 as an example, the electronic device is a television 01, and the broadcast message may be sent by a sound box 02 in a living room and a sweeping robot 03.

In one embodiment, the broadcast message may carry the following information: the device type of the electronic device that sent the broadcast message, the response priority of the electronic device, and the volume at which the electronic device received the wake-up voice. Here, the electronic device type is used to identify the kind of electronic device that transmits the broadcast message. Here, the response priority of the electronic device may be a priority of turning on a voice signal recognition function in response to a voice instruction. For example, the response priority of the first electronic device is higher than the response priority of the second electronic device, and when the first electronic device and the second electronic device simultaneously detect a wake-up voice, the first electronic device preferentially turns on a voice signal recognition function in response to a voice command.

In one embodiment, the broadcast message only carries the device type of the electronic device and the volume at which the wake-up voice is received. Here, the response priority of the electronic device may be implicitly indicated according to the device type of the electronic device. That is, after receiving the broadcast message, the electronic device may determine the response priority of the electronic device that transmits the broadcast message according to the device type of the electronic device carried by the electronic device. For example, if the device type of the electronic device is the first type, the response priority of the electronic device is the first priority.

In one embodiment, the response priority may be determined based on the number of times the electronic device is awakened. The greater the number of times the electronic device is awakened, the higher the response priority of the electronic device. The fewer times the electronic device is awakened, the lower the response priority of the electronic device. For example, the number of times that each electronic device is awakened in a history period may be counted, in which the electronic device that is awakened more often has a high response priority and the electronic device that is awakened less often has a low response priority in the history period. Therefore, the response priority can flexibly change along with the awakening times of the electronic equipment to adapt to the awakening requirement, so that the electronic equipment has higher accuracy and lower false awakening rate when being awakened.

In one embodiment, the response priority may be determined according to a number of times the electronic device was awakened within a set period of time prior to the current time. The more times the electronic device is awakened during the period, the higher the response priority of the electronic device. The fewer times the electronic device is awakened, the lower the response priority of the electronic device.

In one embodiment, the electronic device wakes up at different frequencies during different periods of time, and different response priorities may be set for the electronic device during the different periods of time. For example, a desk lamp with voice wake-up function may set different response priorities in a first time period corresponding to the day and a second time period corresponding to the evening. And a second response priority level during the first period of time, wherein the first response priority level is higher than the second response priority level. Therefore, the response priority can flexibly change along with the working time interval of the electronic equipment to adapt to the awakened requirement, so that the electronic equipment has higher accuracy and lower false awakening rate when being awakened.

In an embodiment, the electronic device wakes up at different frequencies in different scenes, and different corresponding priorities can be set for the electronic device in different scenes. For example, in a first scenario corresponding to a bedroom and a second scenario corresponding to a home theater, a speaker with voice wake-up functionality may set different response priorities. And setting to have a second response priority in the first scene and a first response priority in the second scene, wherein the first response priority is higher than the second response priority. Therefore, the response priority can flexibly change along with the working scene of the electronic equipment to adapt to the awakened requirement, so that the electronic equipment has higher accuracy and lower false awakening rate when being awakened.

In one embodiment, a wake-up voice is determined to be detected when a voice signal is received and the voice signal has a predetermined characteristic. The device sends a broadcast message after detecting the wake-up voice. For example, the television 01, the sound box 02 and the sweeping robot 03 in the living room detect the wake-up voice at the same time, and the sweeping robot 03 and the sound box 02 send a broadcast message to the television 01 after receiving the wake-up voice.

In one embodiment, an electronic device may receive broadcast messages sent by other multiple electronic devices. For example, the television 01 in the living room may receive the broadcast message sent by the sound box 02 and the broadcast message sent by the sweeping robot 03.

In one embodiment, the electronic device obtains the response priority from the broadcast message after receiving the broadcast message. Here, the response priority is a response priority of the transmitting device that transmits the broadcast message.

In one embodiment, in response to the response priority carried by the broadcast message being higher than the response priority of the electronic device, it is determined that the electronic device does not turn on a voice signal recognition function in response to a voice instruction.

In one embodiment, in response to that the response priority carried by each broadcast message is lower than the response priority of the electronic device, it is determined that the electronic device starts a voice signal recognition function responding to a voice command.

In one embodiment, in response to that the response priority carried by each broadcast message is equal to the response priority of the electronic device, it is determined whether the electronic device starts a voice signal recognition function responding to a voice command according to the volume of the detected wake-up voice carried by each broadcast message and the volume of the wake-up voice detected by the electronic device. In one embodiment, when the volume of the detected wake-up voice carried by each broadcast message is greater than the volume of the wake-up voice detected by the electronic device, a voice signal recognition function responding to a voice instruction is not started; and when the volume of the detected awakening voice carried by each broadcast message is smaller than the volume of the awakening voice detected by the electronic equipment, starting a voice signal recognition function responding to a voice instruction.

In one embodiment, after receiving a broadcast message, an electronic device may calculate the number of broadcast messages with response priorities higher than the response priority of the electronic device, which are carried in the broadcast message. When the number is larger than or equal to a number threshold value, determining that the electronic equipment does not start a voice signal recognition function responding to a voice instruction; and when the number is smaller than the number threshold value, determining that the electronic equipment starts a voice signal recognition function responding to the voice instruction. For example, the electronic device is a television, and a fan with a voice recognition function, an air conditioner, a television, a sound box and a floor sweeping robot are arranged in the living room. The priority is in the order of a fan, an air conditioner, a television, a sound box and a sweeping robot from high to low.

If the number threshold is 2, after the fan, the air conditioner, the television, the sound box and the sweeping robot receive the awakening voice, the fan and the air conditioner start a voice signal recognition function responding to the voice instruction because the response priority of the fan and the air conditioner is greater than the response priority of the television, and the television does not start the voice signal recognition function responding to the voice instruction.

If the number threshold is 3, after the fan, the air conditioner, the television, the sound box and the sweeping robot receive the awakening voice, the fan, the air conditioner and the television can start a voice signal recognition function responding to the voice instruction as only the response priority of the fan and the air conditioner is greater than the response priority of the television.

In one embodiment, the voice signal recognition function responsive to the voice instruction may be that the electronic device performs an operation indicated by the voice instruction after receiving the voice instruction. For example, after receiving the voice of the "power off" keyword called out by the user, the electronic device performs the power off operation. In one embodiment, after the voice signal recognition function responding to the voice command is turned on, the electronic device executes the operation indicated by the voice command after receiving the voice command. When the voice signal recognition function responding to the voice command is not started, the electronic equipment cannot execute the operation indicated by the voice command after receiving the voice command.

In the embodiment of the disclosure, the electronic device wakes up the voice by detecting; in response to detecting the wake-up voice, starting a Bluetooth scanning function; scanning, based on the Bluetooth scanning function, broadcast messages sent based on the detection of the wake-up voice; wherein, the broadcast message at least carries a response priority; in this way, the electronic device may scan for a broadcast message transmitted based on the detection of the wake-up voice, and may determine a response priority of a transmitting device that transmits the broadcast message based on a response priority carried in the broadcast message. And the electronic equipment determines whether to start a voice signal recognition function responding to the voice instruction or not based on the response priority carried by the broadcast message and the response priority of the electronic equipment. Therefore, compared with the mode that the electronic equipment starts the voice signal recognition function responding to the voice instruction as long as the awakening voice is detected, the electronic equipment with high response priority can be preferentially made to start the voice signal recognition function responding to the voice instruction, the situation that the electronic equipment with low priority and the electronic equipment with the awakening voice also start the voice signal recognition function responding to the voice instruction is reduced, and therefore when only one electronic equipment with high response priority needs to be awakened, a plurality of electronic equipment which are around and detect the awakening voice cannot be awakened simultaneously, and the experience of using the electronic equipment by a user is improved. In the embodiment of the present disclosure, wireless communication is performed based on the bluetooth scanning function to wake up the electronic device, and compared with wireless communication performed based on a wireless fidelity (wifi) function between the electronic devices in the same local area network, only a wireless communication mode for waking up the electronic devices accessed to the same local area network can be realized, all the electronic devices in a set spatial range can be scanned based on the bluetooth scanning function, and nearby wake-up of the electronic devices in the set spatial range can be realized. As shown in fig. 4, an embodiment of the present disclosure provides a flowchart of a method for waking up a device, as shown in fig. 4, where the method includes the following steps:

and 41, responding to the detection of the awakening voice, and sending the broadcast message based on a Bluetooth protocol.

In one embodiment, the wake-up voice may be a voice signal emitted by a user for controlling the electronic device. Here, the wake-up voice may be a voice signal having a preset characteristic. For example, the wake-up signal may be a wake-up voice containing the keyword "xxx". Here, the preset feature of the wake-up signal may be stored in the electronic device, and when the electronic device receives the voice signal, the voice signal is compared with a voice signal corresponding to the preset feature stored in the electronic device to determine whether the voice signal is the wake-up signal. That is, when the electronic device receives a voice signal, it first determines whether the voice signal is a voice signal conforming to a predetermined characteristic, and only if the voice signal is a voice signal conforming to the predetermined characteristic, a further response operation is performed on the voice signal. For example, it is determined whether the volume of the voice signal is greater than a set volume threshold value, or the like.

In one embodiment, the operating states of the electronic device include a sleep state and an active state. When the electronic device is in a sleep mode, the function of receiving the voice signal is turned on, and the functions other than the function of receiving the voice signal are turned off. For example, a function of receiving a voice signal is turned on, and a bluetooth scan function, a broadcast function, and the like are turned off. The electronic device is only woken up by the wake-up voice with the preset characteristics, and the functions except the function of receiving the voice signal can be turned on. At this time, the electronic device enters an operating state, and the electronic device entering the operating state may respond to an operation instructed by the execution of the voice instruction. Therefore, the electric energy of the electronic equipment is saved, and the standby time of the electronic equipment is prolonged.

In one embodiment, the wake-up tone may be detected periodically. Referring again to fig. 3, the cycle may be divided into a sleep period and a run period. When the electronic equipment is in the dormant period, the electronic equipment stops detecting the awakening voice; and when the electronic equipment is in the operation period, the electronic equipment detects the awakening voice. Here, the ratio of the duration of the sleep period to the duration of the operation period may be determined according to the frequency with which the electronic device is awakened. When the frequency of the electronic device being awakened is greater than the frequency threshold, the time length ratio of the time length of the sleep period to the time length of the operation period may be set to be less than the time length ratio threshold. When the frequency of waking up the electronic device is less than the frequency threshold, the time length ratio of the time length of the sleep period to the time length of the operation period may be set to be greater than the time length ratio threshold. Therefore, the electronic equipment can be ensured to work in a low-energy consumption state, and the electric energy is saved.

In one embodiment, the broadcast message may carry the following information: a device type of the electronic device, a response priority of the electronic device, and a volume at which the wake-up voice is received. Here, the device type is used to identify the kind of the electronic device. Here, the response priority of the electronic device may be a priority of turning on a voice signal recognition function in response to a voice instruction. For example, the response priority of the first electronic device is higher than the response priority of the second electronic device, and when the first electronic device and the second electronic device simultaneously detect a wake-up voice, the first electronic device preferentially turns on a voice signal recognition function in response to a voice command.

In one embodiment, only the device type of the electronic device (e.g., television) and the volume at which the wake-up voice was received are carried in the broadcast message. After receiving the broadcast message, the other electronic device (e.g., a loudspeaker) may determine a priority of sending a response of the electronic device according to the device type of the electronic device carried. Here, it may be the first electronic device that transmits the broadcast message, and the other electronic devices may be the second electronic devices.

In one embodiment, in response to the response priority carried by the broadcast message being higher than the response priority of the second electronic device, the second electronic device may not turn on the voice signal recognition function in response to the voice instruction.

In one embodiment, in response to each broadcast message carrying a response priority lower than the response priority of the second electronic device, the second electronic device may turn on a voice signal recognition function in response to the voice command.

In one embodiment, in response to that the response priority carried by each broadcast message is equal to the response priority of the second electronic device, the second electronic device determines whether the second electronic device starts a voice signal recognition function responding to the voice command according to the volume of the detected wake-up voice carried by each broadcast message and the volume of the wake-up voice detected by the second electronic device. In an embodiment, when the volume of the detected wake-up voice carried by each broadcast message is greater than the volume of the wake-up voice detected by the second electronic device, the second electronic device may not turn on a voice signal recognition function responding to the voice instruction; when the volume of the detected wake-up voice carried by each broadcast message is smaller than the volume of the wake-up voice detected by the second electronic device, the second electronic device may start a voice signal recognition function responding to a voice instruction.

As shown in fig. 5, a flowchart of a method for waking up a device is provided in an embodiment of the present disclosure, and as shown in fig. 5, the determining, based on a response priority carried in the broadcast message and a response priority of the electronic device, whether the electronic device turns on a voice signal recognition function responding to a voice instruction includes:

step 51, in response to that the response priority carried by at least one broadcast message received in a preset time period is higher than the response priority of the electronic equipment, determining that the electronic equipment does not start a voice signal recognition function responding to a voice instruction;

alternatively, the first and second electrodes may be,

In one embodiment, the response priority of the electronic device may be preset. Here, N priority levels may be set, and the user may set a response priority level of the electronic device. Here, N is a positive integer of 1 or more. For example, 3 response priority levels are set, which are a first response priority, a second response priority, and a third response priority, respectively, wherein the first response priority, the second response priority, and the third response priority are ranked from high to low. The user may set the priority of the electronic device to the first response priority when initializing the electronic device. In one embodiment, the response priority of the first electronic device is a first response priority, the response priority of the second electronic device is a second response priority, and the response priority of the first electronic device is higher than the response priority of the second electronic device. Here, the electronic device of high response priority may preferentially turn on the voice signal recognition function in response to the voice instruction.

In one embodiment, after receiving the broadcast messages, the electronic device performs an operation of comparing the response priorities of the electronic device with the response priorities carried in each broadcast message one by one, and determines a size relationship between the response priorities of the electronic device and the response priorities carried in each broadcast message. Here, in response to the magnitude of the response priority carried in at least one broadcast message being larger than the response priority of the electronic device, the operation of comparing the response priorities of the electronic devices one by one with the response priorities carried in the respective broadcast messages may be stopped.

In one embodiment, after receiving the broadcast messages, the electronic device may rank the response priorities carried in each broadcast message, and determine the response priority with the highest response priority. Then, the response priority of the electronic device is compared with the highest response priority to obtain a comparison result.

In one embodiment, in a preset time period, after receiving each broadcast message, the electronic device performs an operation of comparing the response priority of the electronic device with the response priority carried in the broadcast message, and obtains a comparison result.

In one embodiment, after the electronic device receives each broadcast message within a preset time period, that is, after a timer of the preset time period expires, the electronic device performs an operation of comparing the response priority of the electronic device with the response priority carried in the broadcast message, so as to obtain a comparison result.

In one embodiment, the preset period may be determined according to a user's operation. For example, the preset time period is determined according to a received operation instruction of the user. In one embodiment, a setting page of the electronic device may set a plurality of preset time periods for a user to select, and when the electronic device is initialized, one preset time period may be selected according to an operation instruction of the user. Here, when the time delay of the electronic device required to respond to the voice command is smaller than a time delay threshold value, setting a preset time period smaller than the time period threshold value; and when the time delay of the electronic equipment for responding to the voice command is required to be greater than the time delay threshold, setting the preset time interval to be greater than the time interval threshold. Thus, the electronic equipment can respond to the voice command in time. Therefore, the time delay of the electronic equipment responding to the voice instruction can be flexibly adapted to the setting of the preset time period.

As shown in fig. 6, a flowchart of a method for waking up a device is provided in an embodiment of the present disclosure, and as shown in fig. 6, the determining, according to a volume of the detected wake-up voice carried in each broadcast message and a volume of the wake-up voice detected by the electronic device, whether the electronic device responds to a voice signal recognition function of a voice instruction includes:

step 61, in response to that the volume of the detected wake-up voice carried by at least one broadcast message is greater than the volume of the wake-up voice detected by the electronic device, determining that the electronic device does not start a voice signal recognition function responding to a voice instruction;

alternatively, the first and second electrodes may be,

In one embodiment, the electronic device compares the volume of the wake-up voice detected by the electronic device with the volume of the wake-up voice detected in each broadcast message, and determines the relationship between the volume of the wake-up voice detected by the electronic device and the volume of the wake-up voice detected in each broadcast message. Here, in response to that the volume of the detected wake-up voice carried in at least one broadcast message is greater than the volume of the detected wake-up voice of the electronic device, the operation of comparing the volume of the wake-up voice detected by the electronic device with the volume of the detected wake-up voice carried in each broadcast message is stopped.

In an embodiment, the electronic device may sequence the detected volumes of the wake-up voices carried in the broadcast messages, and determine the detected volume of the wake-up voice with the largest detected volume of the wake-up voices. Then, comparing the volume of the wake-up voice detected by the electronic equipment with the highest detected volume of the wake-up voice to obtain a comparison result.

As shown in fig. 7, an embodiment of the present disclosure provides a flowchart of a method for waking up a device, and as shown in fig. 7, the method further includes:

step 71, in response to that the broadcast message is not scanned in the preset time period, determining that the electronic device starts a voice signal recognition function responding to a voice instruction.

in this example, the scene is applied to a smart home, and electronic devices in the smart home include a sound box, a television and a desk lamp. The method for waking up the equipment comprises the following steps:

step a1, the user calls out the awakening word of the love classmate to awaken the sound box. After each electronic device is awakened, a Low power consumption Bluetooth (BLE) scanning function and a broadcasting function are simultaneously started. Wherein a Bluetooth Low Energy (BLE) scanning function is used to scan for broadcast messages. The broadcast function is used to send the broadcast message. The broadcast message carries: the device type of the electronic device, the response priority of the electronic device, and the volume at which the electronic device receives the wake-up word.

Step a2, in a preset time period, if the sound box scans the broadcast message and the sound box determines that the response priority of the television is higher than that of the sound box according to the response priority of the television carried by the broadcast message, the sound box determines to close the voice recognition function responding to the voice instruction and does not perform Natural Language Processing (NLP) recognition any more.

Step a3, in a preset time period, if the sound box scans the broadcast message and determines that the corresponding priority of all the electronic devices (television and desk lamp) is less than the response priority of the sound box according to the response priority of the electronic devices carried by the broadcast message, the sound box starts the voice recognition function responding to the voice instruction and performs Natural Language Processing (NLP) recognition outside the preset time period, namely after the timer indicating the preset time period is overtime.

Step a4, if the broadcast message sent by the electronic device is not scanned in the preset time period, the sound box will start the voice recognition function responding to the voice instruction to perform Natural Language Processing (NLP) recognition.

Step a5, if the scanned broadcast message of the electronic device and the loudspeaker box determine that the electronic device sending the broadcast message is the same type of device according to the device type, judging whether to perform Natural Language Processing (NLP) recognition according to the volume of the wake-up word received by the electronic device sending the broadcast message. If the volume of the awakening word received by the electronic equipment sending the broadcast message is larger than that of the awakening word received by the sound box, the sound box defaults to close the voice recognition function responding to the voice instruction and does not perform Natural Language Processing (NLP) recognition; otherwise, the sound box starts a voice recognition function responding to the voice command, and Natural Language Processing (NLP) recognition is carried out.
