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 implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flowchart of an information processing method shown in an embodiment of the present disclosure, which is applied to a first device, and as shown in fig. 1, the information processing method includes the following steps:

s11, receiving a voice instruction;

s12, determining whether the ultrasonic signal transmitted by the second equipment is received when the voice instruction is received; wherein the second device is a mobile device;

and S13, if the ultrasonic signal is received, responding to the voice command.

In the embodiment of the disclosure, the first device is a voice device, and the voice device supports the functions of voice acquisition and audio output, so that the voice interaction between the human and the machine can be realized on the basis. The voice device includes: and the intelligent sound box or other Internet of things equipment supporting the voice interaction function. Furthermore, the first device may also receive ultrasonic signals, for example using a built-in microphone.

The second device is a mobile device, and the mobile device includes a device that is movable based on the mobile carrying of the user, such as a terminal device that is convenient for the user to carry, for example, a smartphone or a wearable device. Furthermore, the second device may also emit ultrasonic signals, for example using a built-in speaker.

In steps S11 to S13, the first device receives the voice command, determines whether the ultrasonic signal transmitted by the second device is received when the voice command is received, and responds to the voice command if the ultrasonic signal is received by the first device.

Take the example that the first device is a smart speaker and the second device is a smart phone. The smart phone periodically transmits the ultrasonic signal, and the smart phone can move along with the movement of the user in the process of transmitting the ultrasonic signal because the smart phone is carried by the user. When the intelligent sound box receives a voice command of turning on the lamp and receives an ultrasonic signal transmitted by the smart phone based on the approach of the smart phone, the intelligent sound box responds to the command of turning on the lamp and sends a control command to the intelligent lamp related to the command of turning on the lamp in advance so as to turn on the intelligent lamp.

It should be noted that, because the receiving range of the ultrasonic signal is limited and the ultrasonic signal has no penetrability, for example, the distance between the transmitting device and the receiving device of the ultrasonic signal needs to be within 3 to 4 meters, and there is no wall barrier between the transmitting device and the receiving device, in the embodiment of the present disclosure, it can be effectively determined whether two devices are nearby and there is no barrier between the two devices (for example, the same room) by using the characteristics of the ultrasonic wave.

For another example, when there are a plurality of smart speakers, the plurality of smart speakers may all receive the voice command, and since the reception range of the ultrasonic signal is limited and the ultrasonic signal does not have penetrability, the smart speaker that can receive the ultrasonic signal may respond to the voice command in close proximity.

In some embodiments, there are bluetooth-based, Wireless-Fidelity (Wi-Fi), Near Field Communication (NFC), and Ultra Wide Band (UWB) based schemes to determine whether two devices are nearby. However, in the bluetooth and Wi-Fi schemes, the signal penetration is too strong and easy to penetrate through the wall, so that it is impossible to accurately judge whether two objects are nearby and have no blocking in the middle, and thus there may be a problem of erroneous control. For example, the first device receives an instruction from the user to shout "light" in the same room, and may turn on the light outside the room, rather than the light in the room where the user is located, since the user may be closer to the light outside the wall. In addition, in the above NFC and UWB schemes, the effective distance is short and hardware support is required, so that there may be problems of inefficient control and high cost.

As can be seen from the comparison, the first electronic device of the present disclosure further determines whether the ultrasonic signal transmitted by the second device is received when receiving the voice instruction, and responds to the voice instruction when determining that the ultrasonic signal is received. The receiving range based on ultrasonic wave signal has the restriction and ultrasonic wave signal does not have the penetrability, therefore can effectively judge whether two equipment are near and do not block between two equipment to promote the precision of closely controlling, promote the user and use experience.

In addition, when the first electronic device is internally provided with the microphone, the microphone can be used for receiving ultrasonic signals, and the close-range control with higher precision can be realized without additional hardware support, so that the cost can be saved.

In one embodiment, the ultrasonic signal carries identification information of the second device; the identification information of the second device is used for determining whether the second device is an authorized device having the authority of triggering the voice instruction response.

In this embodiment, the ultrasonic signal further carries identification information of the second device, where the identification information includes at least one of:

a device serial number;

universal Unique Identifier (UUID);

a physical Address (MAC).

The identification information may uniquely identify the second device for determining whether the second device is an authorized device having the authority to trigger a response to the voice command.

It should be noted that, in the embodiment of the present disclosure, whether the second device is an authorized device may be determined by the first device, for example, after the first device receives the ultrasonic signal of the second device and acquires the identification information, whether the second device is an authorized device that can control the first device is determined based on the identification information of the legitimate device that is authorized to respond to the voice command and stored in the cloud. Additionally, whether the second device is an authorized device may also be determined by a cloud associating the first device and the second device. For example, after receiving an ultrasonic signal of the second device and acquiring identification information, the first device uploads the identification information of the second device to the server, and receives a notification message sent by the server after determining that the first device and the second device are devices associated with the same user account, and the first device can determine that the second device is an authorized device with a trigger voice instruction response permission based on the received notification message.

In another embodiment, the identification information may also be: during the authorization process in response to a voice command, when detecting an ultrasonic signal sent by the second device, the first device assigns any unique identifier of the second device, which may not have any relation with the hardware identifier (e.g., MAC address) of the second device, and the unique identifier may be an authorization Serial Number (SN) in the authorization process. After authorization, the second device stores the authorization serial number locally or in the cloud.

In one embodiment, step S13 includes:

In this embodiment, based on the identification information of the second device carried in the ultrasonic signal, when it is determined that the second device is an authorized device, the voice instruction is responded based on the ultrasonic signal of the authorized device.

It can be understood that the safety of the close range control can be improved by responding to the voice command after the ultrasonic signal transmitted by the authorized second device is determined to be received.

As previously mentioned, the second device may be a mobile device. In one embodiment, the second device may also be a stationary device. For example, the first device is a smart speaker and the second device is a smart light. The intelligent lamp periodically transmits ultrasonic signals, when the intelligent sound box receives a voice command of turning on the lamp, and the intelligent sound box receives the ultrasonic signals transmitted by the intelligent lamp, the voice command of turning on the lamp is responded, and a control command is sent to the second equipment based on the identification information of the second equipment, so that the intelligent lamp is turned on. In this embodiment, no association relationship is established in advance between the first device and the second device, and thus the proximity control can be realized by the ultrasonic signal and the identification information carried in the ultrasonic signal.

In another embodiment, the first device may also be: smart windows and doors or smart curtains, etc., and the second device may be a mobile device, etc.

In one embodiment, step S13 includes:

In this embodiment, if the first device receives the ultrasonic signal, the first device further responds to the voice command when the signal strength of the ultrasonic signal satisfies the strength condition. Since the closer the distance between the first device and the second device is, the greater the signal intensity of the ultrasonic signal is, the more the precision of the close-range control can be improved by this means.

In one embodiment, the signal strength of the ultrasonic signal satisfies an intensity condition, including:

In this embodiment, the condition that the signal strength of the ultrasonic signal satisfies the strength condition includes that the signal strength of the ultrasonic signal is greater than a strength threshold, and the distance between the first device and the second device, which is determined according to the signal strength of the ultrasonic signal, is less than a distance threshold.

It should be noted that, in this embodiment, the distance between the first device and the second device may be determined based on the signal strength of the ultrasonic signal. In another embodiment, when two or more ultrasonic signal receivers (e.g., two microphones) are included in the first device, the distance of the first device and the second device may also be calculated based on the time difference at which the ultrasonic signals are received by the different ultrasonic signal receivers.

Fig. 2 is a flowchart of an information processing method shown in the embodiment of the present disclosure, which is applied to a second mobile device, and as shown in fig. 2, the information processing method includes the following steps:

s21, transmitting an ultrasonic signal; the ultrasonic signal is used for responding to a voice instruction received by the first equipment after being received by the first equipment.

In an embodiment of the present disclosure, the second device is a mobile device, which includes a device that is movable based on a mobile carrying of the user, such as a smartphone or a wearable device; the mobile device also comprises a device which can control the self-moving device based on the instruction, such as a sweeping robot and the like.

The second device may emit an ultrasonic signal, for example, using a built-in speaker. The loudspeaker can be an audio output device which can originally output sound waves heard by a user, so that the original existing loudspeaker in the equipment outputs ultrasonic signals is multiplexed, a device specially outputting the ultrasonic signals is not additionally introduced, the equipment structure is simplified, and the hardware cost is reduced.

In the embodiment of the present disclosure, the second device may periodically transmit the ultrasonic signal at a certain time interval, and may also continuously transmit the ultrasonic signal, which is not limited by the present disclosure.

And the ultrasonic signal transmitted by the second equipment is used for responding to the voice command received by the first equipment after the first equipment receives the ultrasonic signal. Because the receiving range of the ultrasonic signal is limited and the ultrasonic signal has no penetrability, if the first device can receive the ultrasonic signal, the first device and the second device are close to each other and no barrier exists between the two devices. Therefore, this disclosure can promote the precision of close range control through ultrasonic signal's mode, promotes the user and uses experience.

In this embodiment, the ultrasonic signal further carries identification information of the second device, where the identification information can uniquely identify the second device, and is used to determine whether the second device is an authorized device having a trigger voice instruction response authority. It can be understood that, the second device carries the identification information of the second device in the transmitted ultrasonic signal, so that the first device can respond to the voice command after determining that the received ultrasonic signal transmitted by the authorized second device is received, and the security of the close-range control can be improved.

In one embodiment, the method further comprises:

when the ultrasonic signal does not carry identification information or carries wrong identification information and carries request information for requesting to respond to a voice command, prompt information is output, and the prompt information can be a voice prompt output by first equipment, a text prompt output by second equipment based on the instruction of the first equipment, or an authorization prompt sent by the first equipment to control equipment.

In short, the prompt message is used to prompt the legitimate user whether to grant the current second device with the authority to trigger the voice instruction.

During the authorization process, the authentication of the authorization password is required to ensure the security of the authorization.

Fig. 3 is an interaction flowchart of an information processing method in an embodiment of the present disclosure, and as shown in fig. 3, the information processing method applied to a first device and a movable second device includes the following steps:

s31, the second equipment transmits ultrasonic signals;

s32, the first equipment receives a voice instruction;

s33, the first equipment determines whether the ultrasonic signal transmitted by the second equipment is received when the voice instruction is received;

and S34, if the first equipment receives the ultrasonic signal, responding to the voice command.

In an embodiment of the present disclosure, the second device may transmit an ultrasonic signal, and the first electronic device may further determine whether the ultrasonic signal transmitted by the second device is received when receiving the voice instruction, and respond to the voice instruction when determining that the ultrasonic signal is received. The receiving range based on ultrasonic wave signal has the restriction and ultrasonic wave signal does not have the penetrability, therefore can effectively judge whether two equipment are near and do not block between two equipment to promote the precision of closely controlling, promote the user and use experience.

In addition, when the first electronic device is internally provided with a microphone and the second electronic device is internally provided with a loudspeaker, the loudspeaker can be used for emitting ultrasonic signals, and the microphone can be used for receiving the ultrasonic signals, so that the close-range control with higher precision can be realized without additional hardware support, and the cost can be saved.

The method further comprises the following steps:

the first equipment receives a configuration instruction;

sending transmission parameters for configuring the ultrasonic signal transmission to the second equipment according to the configuration instruction, wherein the transmission parameters at least comprise: the transmit power.

The transmitting power of the ultrasonic signal determines the distance between the monitoring equipment capable of successfully monitoring the ultrasonic signal and the second equipment, and the transmitting power is positively correlated with the distance. In the embodiment of the disclosure, the transmitting power of the second device for transmitting the ultrasonic wave is configured by the first device, so that individual configuration of different first devices can be realized. The first device may directly send the configuration instruction to the second device through a direct communication link with the second device, or may send the configuration instruction to the second device through a network.

In another embodiment, the transmission parameters may further include: the transmit frequency, etc. The higher the transmission frequency is, the denser the ultrasonic wave transmitted by the second device is under the condition of changing the same distance, the higher the frequency of the ultrasonic wave signal monitored by the first device is, so that the response rate can be improved.

In one embodiment, the transmission parameters include: transmitting an extremum of the parameter, the extremum may include: minimum and maximum values, thus facilitating the second device to select the transmission parameters suitable for the current state according to the state of the second device and/or the wireless environment and according to the extreme values of the transmission parameters.

For example, taking the transmission power as an example, the transmission parameters include: the second device can select target transmitting power adapted to the residual capacity between the maximum value and the minimum value of the transmitting power according to the residual capacity of the second device, so that the ultrasonic wave signal can be transmitted according to the target transmitting power. The remaining capacity is positively correlated with the transmission power.

For example, taking the transmission frequency as an example, the transmission parameters include: the second device can select a target transmitting frequency adapted to the residual capacity between the maximum value and the minimum value of the transmitting frequency according to the residual capacity of the second device, so that the ultrasonic wave signal can be transmitted according to the target transmitting frequency. The remaining capacity is positively correlated with the transmission frequency.

For another example, in the case of large interference of the current ultrasonic signal, the transmission power and/or the transmission frequency may be appropriately reduced to suppress further complexity of the wireless environment.

In summary, the above is merely an example, and the specific implementation is not limited thereto.
