Detailed Description

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

Firstly, describing an application scenario of the present disclosure, the present disclosure may be applied to a scenario of voice wake-up, where at present, a vehicle control end in a vehicle may support voice wake-up, and control a target device (such as an air conditioner or an in-vehicle device such as a sound device) in the vehicle through a voice command.

In the related art, a wireless connection between a vehicle control terminal and each terminal device in the vehicle may be established, and the vehicle control terminal may send a wake-up suppression instruction to each terminal device according to the wireless connection, so as to suppress a response of each terminal device to a voice wake-up word. However, this method needs to establish wireless connection with each terminal device in the vehicle in advance, the implementation process is complex, and in the case of many terminal devices in the vehicle, it cannot be ensured that the wireless connection is established between the vehicle control terminal and all the terminal devices, so the problem that a plurality of devices respond to voice wake-up words still exists.

In order to solve the problems, the disclosure provides a device control method, a device, an electronic device, a storage medium and a vehicle, wherein the method is capable of receiving a wake-up suppression instruction through an ultrasonic signal, does not need to establish wireless connection between a first device and a second device, has a simpler implementation process, and can ensure that a plurality of first devices in the vehicle all receive the wake-up suppression instruction, so that the problem that a plurality of devices respond to a voice wake-up word is avoided.

The present disclosure is described below in connection with specific embodiments.

Fig. 1 is a flowchart of a method for controlling a device according to an exemplary embodiment of the present disclosure, and as shown in fig. 1, the method may be applied to a first device, and the method includes:

Step 101, receiving an ultrasonic signal sent by the second device through the ultrasonic transmitting device, wherein the ultrasonic signal comprises a wake-up inhibition instruction.

The first device may be a terminal device of a user in the vehicle, which may be a cellular phone, a cordless phone, a session initiation protocol (session initiationprotocol, SIP) phone, a handheld device with a voice wake-up function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, and a next generation communication system, for example, a terminal device in a fifth generation communication (fifth-generation, 5G) network or a terminal device in a future evolved public land mobile network (public land mobile network, PLMN) network, a terminal device in a new air interface (NR) communication system, etc. The second device may be a vehicle control end, the ultrasonic transmitting device may be a horn in a vehicle, for example, the second device may encode the wake-up suppression instruction to obtain an encoded instruction, load the encoded instruction onto an ultrasonic signal with a preset signal frequency, send the ultrasonic signal to the first device through the ultrasonic transmitting device, and after receiving the ultrasonic signal, the first device analyzes the ultrasonic signal to obtain the encoded instruction, and decodes the encoded instruction to obtain the wake-up suppression instruction.

Because the signal frequency of the ultrasonic signal is large, the ultrasonic signal can not be perceived by human ears, so that the awakening inhibition instruction transmitted by the ultrasonic signal can not influence the hearing of a user, and the information can be quickly restored by transmitting the ultrasonic signal, the ultrasonic wave has relatively short wavelength and high safety, and meanwhile, the network connection between devices is not required to be established, so that electromagnetic interference is avoided.

And 102, stopping responding to the received voice wake-up word according to the wake-up suppression instruction.

The voice wake-up word can be 'small X', or 'small X classmates', and the like.

By adopting the method, the wake-up inhibition instruction can be transmitted through the ultrasonic signal, the wireless connection between the first equipment and the second equipment is not required to be established, and the implementation process is simpler.

In some embodiments, the step 101 may include two implementations:

in a first implementation, a voice wake instruction may be received, the voice wake instruction including the voice wake word; accordingly, step 101 may include: and under the condition that the voice wake-up word is successfully matched with a first preset wake-up word corresponding to the first equipment, receiving an ultrasonic signal sent by the second equipment through the ultrasonic transmitting device in a preset time period. In this way, when the first device receives the ultrasonic signal sent by the second device through the ultrasonic transmitting device in the preset time period, according to the wake-up inhibition instruction, the first device stops responding to the received voice wake-up word, and does not need to monitor the ultrasonic signal in real time, so that the power consumption of the device is saved.

The user can speak the voice wake-up instruction, and the voice wake-up instruction can be input through a voice input device, and the voice input device can be a microphone.

In this manner, after the first device receives the voice wake-up word, it may determine whether the voice wake-up word is successfully matched with a first preset wake-up word corresponding to the first device, where the first preset wake-up word is a preset wake-up word capable of switching the first device from a sleep state to a wake-up state, and one possible implementation manner is that it may be determined whether the voice wake-up word is identical to the first preset wake-up word, and if the voice wake-up word is identical to the first preset wake-up word, it is determined that the voice wake-up word is successfully matched with the first preset wake-up word, that is, the voice wake-up word is capable of switching the first device from the sleep state to the wake-up state, and if the voice wake-up word is different from the first preset wake-up word, it is determined that the voice word is failed to be matched with the first preset wake-up word.

For example, if the preset wake word "little X classmate" corresponding to the first device is also "little X classmate", it is determined that the voice wake word is successfully matched with the preset wake word corresponding to the first device, and if the preset wake word "little X" corresponding to the first device is not "little X classmate", it is determined that the voice wake word is failed to be matched with the preset wake word corresponding to the first device.

For example, when the voice wake-up word is successfully matched with the first preset wake-up word, the first device may switch to a listening state, where the listening state characterizes that the first device does not respond to the voice wake-up word in a preset time period, and listens for an ultrasonic signal sent by the second device through the ultrasonic transmitting device in the preset time period; under the condition that the voice wake-up word is successfully matched with a second preset voice wake-up word corresponding to the second equipment, the second equipment can perform two processes, wherein one process is to generate a wake-up suppression instruction, an ultrasonic signal comprising the wake-up suppression instruction is sent through an ultrasonic wave transmitting device, the other process is to respond to the voice wake-up word, and under the condition that the first equipment receives the ultrasonic signal sent by the second equipment through the ultrasonic wave transmitting device in the preset time period, the response of the received voice wake-up word is stopped according to the wake-up suppression instruction.

If the preset time period is reached, the first device does not receive the ultrasonic signal, which indicates that the response inhibition to the voice wake-up word is not needed (i.e. the response to the voice wake-up word is not needed), so that the voice wake-up word can be responded.

For example, a response speech word may be output in response to the voice wake word, which may be a speech word such as "tweed" or "I am".

And under the condition that the voice wake-up word fails to match with the first preset wake-up word, the first equipment does not respond to the voice wake-up word.

It should be noted that, when the voice wake-up word fails to match with the first preset wake-up word, the first device will not monitor the ultrasonic signal sent by the second device through the ultrasonic transmitting device, that is, when the voice wake-up word fails to match with the first preset wake-up word, the first device will not receive the ultrasonic signal sent by the second device through the ultrasonic transmitting device.

In some embodiments, when the second device determines that the voice wake is successfully matched with the second preset voice wake, the first device may periodically receive the ultrasonic signal sent by the second device through the ultrasonic transmitting device, so as to ensure that the first device successfully receives the ultrasonic signal in a preset time period.

In this embodiment, since the second device periodically transmits the ultrasonic signal through the ultrasonic transmitting device may cause higher power consumption of the second device, in order to solve the problem, in another implementation manner, the second device may receive the ultrasonic signal periodically transmitted through the ultrasonic transmitting device during the preset period, so that the first device may periodically receive the ultrasonic signal transmitted through the ultrasonic transmitting device during the period when the second device monitors the ultrasonic signal, thereby not only ensuring that the first device successfully receives the ultrasonic signal, but also avoiding the problem of higher power consumption caused by long-term periodic transmission of the ultrasonic signal by the second device.

It should be noted that, when the preset time period is reached, the second device may stop sending the ultrasonic signal through the ultrasonic transmitting device, and re-determine whether the voice wake-up word is successfully matched with the second preset wake-up word when the voice wake-up word uttered by the user is received again, and periodically send the ultrasonic signal through the ultrasonic transmitting device in the preset time period when the voice wake-up word is successfully matched with the second preset wake-up word.

In a second implementation, an ultrasonic signal periodically transmitted by the second device through the ultrasonic transmitting device may be received. In this way, by periodically receiving the ultrasonic signal, it can be ensured that the ultrasonic signal can be received by each of the plurality of first devices.

By way of example, the transmission period of the ultrasonic signal transmitted by the second device through the ultrasonic transmission means may be 1 to 30 seconds, such as 1 second, 10 seconds, 20 seconds, 30 seconds, or the like, for example, by taking the transmission period of 30 seconds as an example, the second device starts timing after transmitting the ultrasonic signal through the ultrasonic transmission means, and when 30 seconds are reached, transmits the ultrasonic signal again, and so on,

In this manner, the ultrasonic signal may further include a designated wake-up word, and accordingly, the step S102 may include: and stopping responding to the received voice wake word under the condition that the voice wake word is matched with the appointed wake word. Thus, aiming at the appointed wake-up word, the response of the first equipment to the voice wake-up word can be flexibly controlled through the matching of the voice wake-up word and the appointed wake-up word.

The specified wake-up word may include a second preset voice wake-up word corresponding to the second device, so that response suppression can be performed on the first device identical to the voice wake-up word of the second device, and the first device and the second device are prevented from simultaneously responding to the voice wake-up word to affect user experience.

Taking a first device to support a plurality of preset wake words as an example, the preset wake words supported by the first device may include "small X" and "small X classmates", the specific wake word included in the ultrasonic signal is "small X classmates", if the voice wake word is also "small X classmates", the voice wake word and the specific wake word are successfully matched, and the first device stops responding to the voice wake word "small X classmates"; if the voice wake-up word is 'small X', the voice wake-up word fails to match with the appointed wake-up word, and the first device responds to the wake-up word 'small X'. Thus, only the response of the "small X" in the "small X classmates" and the "small X" in the preset wake-up words of the first device can control the response of the first device to the partial voice wake-up words supported by the first device.

For another example, taking an example that there are a plurality of first devices and each first device supports a preset wake-up word, assume that there are 3 first devices in the vehicle, which are respectively denoted as device 1, device 2 and device 3, where the preset wake-up word supported by device 1 is: "hey, small X", the preset wake-up words supported by device 2 are: "hello, small X", the preset wake-up words supported by device 3 are: "hello, small X", the ultrasonic signal includes the appointed wake-up word "hey, small X", if the voice wake-up word is "hey, small X", the voice wake-up word and the appointed wake-up word are successfully matched, the equipment 1 stops responding to the voice wake-up word "hey, small X"; if the voice wake-up word is hello, the small X ", the device 2 still responds to the voice wake-up word, and similarly, if the voice wake-up word is hello, the small X", the device 3 also responds to the voice wake-up word, so that through the designated wake-up word in the ultrasonic signal, the response of the device corresponding to the designated wake-up word can be suppressed, the response of other devices to the corresponding voice wake-up word is not suppressed, and thus a part of a plurality of devices supporting different preset wake-up words can be controlled to respond to the voice wake-up word.

It should be noted that, in the first implementation manner, the second device defaults to not send an ultrasonic signal, and only when a voice wake-up instruction of a user is received and the voice wake-up word in the voice wake-up instruction is successfully matched with a second preset wake-up word corresponding to the second device, the ultrasonic signal is transmitted through the ultrasonic transmitting device, and the first device enters a monitoring state and monitors the ultrasonic signal transmitted by the second device through the ultrasonic transmitting device when the voice wake-up word in the voice wake-up instruction is successfully matched with the first preset wake-up word corresponding to the first device; the second implementation mode is that the second equipment actively and periodically transmits the ultrasonic signal without receiving a voice wake-up instruction of the user.

In another embodiment, when the first device receives the ultrasonic signal including the wake-up suppression time, the first device may stop responding to the voice wake-up word within a preset suppression time period, where the preset suppression time period may be greater than or equal to a transmission period of the ultrasonic signal sent by the second device through the ultrasonic transmission device, so as to ensure that the first device is continuously in a state of stopping responding to the voice wake-up word.

In some embodiments, the ultrasonic signal may further include a wake-up suppression time, and the step S102 may include: and stopping responding to the received voice wake-up word in the wake-up inhibition time according to the wake-up inhibition instruction. In this way, the time when the first device enters the state of stopping the response to the voice wake may be indicated by the ultrasonic signal, so that the response of the first device to the voice wake may be controlled more flexibly.

Taking the first device as a terminal device and the second device as a vehicle control end as an example, when the user carries the terminal device and is located in the vehicle, the terminal device receives an ultrasonic signal comprising a wake-up suppression time, and stops responding to the received voice wake-up word in the wake-up suppression time.

Illustratively, the wake-up suppression time may be set to 1 to 30 seconds, such as 1 second, 10 seconds, 15 seconds, 20 seconds, or 30 seconds, as the present disclosure is not limited thereto.

In addition, regarding the scenario that the first device receives the ultrasonic signal periodically sent by the second device through the ultrasonic wave transmitting device, considering that if the wake-up suppression time is smaller than the transmission period of the ultrasonic signal sent by the second device, the first device may not yet receive the ultrasonic signal sent by the second device after reaching the wake-up suppression time, at this time, the first device may switch from a state of stopping responding to the voice wake-up word to a state of starting responding to the voice wake-up word, thereby affecting the user experience, and therefore, the wake-up suppression time may be greater than or equal to the transmission period of the ultrasonic signal sent by the second device.

It should be noted that, in the case that the wake-up suppression time is greater than the transmission period of the ultrasonic signal transmitted by the second device, the first device may receive the ultrasonic signal multiple times within the wake-up suppression time, and each time the ultrasonic signal is received, the wake-up suppression time recorded currently may be refreshed according to the wake-up suppression time in the received ultrasonic signal, so as to reckon according to the wake-up suppression time in the newly received ultrasonic signal.

For example, the wake-up suppressing time is 30 seconds, the transmission period is 15 seconds, the first device stops the response to the voice wake-up word within 30 seconds after receiving the ultrasonic signal, and when the first device counts to 15 seconds, the first device remains in a state of stopping the response to the voice wake-up word for 15 seconds, and at this time, when the second device receives the ultrasonic signal including the wake-up suppressing time again, the remaining 15 seconds are refreshed to 30 seconds, and the response to the voice wake-up word is suppressed in accordance with 30 seconds after the refresh. The wake-up suppression times and transmit periods described above are merely illustrative and are not limiting of the present disclosure.

Fig. 2 is a flowchart of another method of device control provided in accordance with an exemplary embodiment, as shown in fig. 2, the method being applicable to a second device, the method comprising:

step 201, generating a wake-up suppression instruction.

The wake-up suppression instruction is used for indicating the first device to stop responding to the voice wake-up word.

In some embodiments, the wake-up suppression instruction may be generated if a preset signal trigger condition is met.

The preset signal triggering condition may be, for example: the second device is powered up.

It should be noted that the second device may be a control end of the vehicle, and correspondingly, the preset signal triggering condition may include power-on of the vehicle.

In addition, in consideration of that the user of the vehicle may not enter the vehicle after the vehicle is powered on, at this time, there may not be a need for suppressing the response of the terminal device of the user, and thus, in other embodiments, the preset signal triggering condition may further include the vehicle control end detecting that the vehicle door is closed.

Step 202, sending an ultrasonic signal containing the wake-up suppression instruction through an ultrasonic sending device, where the wake-up suppression instruction is used to instruct the first device to stop responding to the received voice wake-up word.

The second device may encode the wake-up suppression instruction to obtain an encoded instruction, load the encoded instruction onto an ultrasonic signal with a preset signal frequency, and transmit the ultrasonic signal including the wake-up suppression instruction through the ultrasonic transmitting device.

Because the signal frequency of the ultrasonic signal is large, the ultrasonic signal cannot be perceived by human ears, so that the awakening inhibition instruction transmitted by the ultrasonic signal cannot influence the hearing of a user, and the information can be quickly restored by transmitting the ultrasonic signal. Therefore, the ultrasonic wave has relatively short wavelength and high safety, and meanwhile, network connection between devices is not required to be established, so that electromagnetic interference is avoided.

In some embodiments, the step 201 may include: and under the condition that a voice wake-up instruction is received, generating a wake-up suppression instruction, wherein the voice wake-up instruction comprises the voice wake-up word. In this way, under the condition that the voice wake-up instruction is received, the wake-up inhibition instruction is generated, and the ultrasonic signal containing the wake-up inhibition instruction is sent through the ultrasonic wave transmitting device, so that the second device can effectively control the sending of the ultrasonic signal without periodic sending, and the power consumption of the second device is saved.

For example: the voice wake-up word can be preconfigured or customized by a user, such as 'little X', 'little X classmate', and the like.

In consideration of that the voice wake-up word in the voice wake-up instruction may not be a voice wake-up word for waking up the second device, the second device may not respond to the voice wake-up word, in this case, it indicates that the user needs are not to wake up the second device, at this time, if the second device sends an ultrasonic signal, the user wants to wake up the device to stop responding to the voice wake-up word, so as to affect the user experience, in order to solve the problem, in a possible implementation manner, the voice wake-up instruction may include the voice wake-up word under the condition that the voice wake-up instruction is received, and if the voice wake-up word is successfully matched with the second preset wake-up word corresponding to the second device, a wake-up suppression instruction is generated. In this way, when the voice wake-up word is successfully matched with the second preset wake-up word corresponding to the second device, a wake-up suppression instruction is generated, and an ultrasonic signal containing the wake-up suppression instruction is sent, so that the response of the first device, which is identical to the second preset voice wake-up word corresponding to the second device, to the voice wake-up word can be accurately suppressed.

In some embodiments, the step 202 may include: an ultrasonic signal including the wake-up suppression instruction is periodically transmitted by an ultrasonic transmitting device.

And the second equipment continuously transmits ultrasonic signals to the terminal equipment through the ultrasonic transmitting device according to the transmitting period. In this way, by periodically transmitting the ultrasonic signal, it can be ensured that the first device successfully receives the ultrasonic signal.

In some embodiments, the ultrasonic signal further comprises a specified wake word for instructing the first device to cease responding to the specified wake word.

The appointed wake-up word can be subjected to user-defined setting, and the response of the first equipment to the voice wake-up word can be flexibly controlled through the matching of the received voice wake-up word and the appointed wake-up word.

In some embodiments, the ultrasonic signal further comprises a wake-up suppression time for instructing the first device to cease responding to the voice wake-up word within the wake-up suppression time.

The response of the first device to the voice wake-up word can be controlled more finely by stopping the response to the voice wake-up word in a certain time through the wake-up inhibition time.

It should be noted that, for the description of the above implementation manner in this embodiment, reference may be made to the related description in the foregoing embodiment, which is not repeated here.

By adopting the method, the wake-up inhibition instruction can be transmitted through the ultrasonic signal, the wireless connection between the first equipment and the second equipment is not required to be established, and the implementation process is simpler.

Fig. 3 is a flowchart of a method for controlling devices according to an exemplary embodiment, as shown in fig. 3, in which a first device may be a terminal device of a user in a vehicle, and a second device may be a vehicle control end, and the method includes:

step 301, the vehicle control terminal receives a voice wake-up instruction input by a user.

The voice wake instruction includes a voice wake word, and the voice wake word may be "small X" or "small X classmates", for example.

For example, the user may speak the voice wake.

Step 302, the vehicle control end determines whether the voice wake-up word is successfully matched with a second preset voice wake-up word corresponding to the vehicle control end under the condition that the voice wake-up word input by the user is received.

The second preset voice wake-up word may be preconfigured by the vehicle control end.

Executing step 303 when the voice wake-up word is successfully matched with a second preset voice wake-up word corresponding to the vehicle control end;

and under the condition that the voice wake-up word is not matched with a second preset voice wake-up word corresponding to the vehicle control end, executing step 310.

Step 303, the vehicle control end generates a wake-up suppression instruction and sends an ultrasonic signal containing the wake-up suppression instruction through the ultrasonic transmitting device.

Step 304, the vehicle control end responds to the voice wake-up word.

Step 305, the terminal device receives the voice wake-up instruction including the voice wake-up word.

Step 306, the terminal device determines whether the voice wake-up word is successfully matched with a first preset voice wake-up word corresponding to the terminal device.

Executing step 307 when the voice wake-up word is successfully matched with the first preset voice wake-up word corresponding to the terminal device;

and executing step 311 under the condition that the voice wake-up word is not matched with a second preset voice wake-up word corresponding to the terminal equipment.

Step 307, the terminal device determines whether an ultrasonic signal sent by the second device through the ultrasonic transmitting device is received within a preset time period.

Executing step 308 when the ultrasonic signal sent by the second device through the ultrasonic transmitting device is received within the preset time period;
