Please refer to FIG. 1, which is a flowchart of an electronic device control method provided by an embodiment of the present application. The method is applied to the electronic device described in the above embodiment, and may include the following steps:

101. Acquire voice information of a user, and extract voiceprint features and instruction information in the voice information.

The voice information can be obtained through a microphone of the electronic device. Specifically, the electronic device can continuously obtain the ambient sound through the microphone, store the ambient sound into the cache, and perform real-time matching.

To extract the voiceprint features in the voice information, the voiceprint features in the voice information can be extracted by an extraction algorithm known to those skilled in the art. The voiceprint feature may include one or more features such as a broadband voiceprint, a narrowband voiceprint, an amplitude voiceprint, a contour voiceprint, a time-spectrum voiceprint, and a cross-section voiceprint, which are not exhaustively listed here.

In some embodiments, in order to trigger the extraction of voiceprint features and instruction information in the voice information, a voice instruction preceding the wake-up word may be set to wake up the extraction function of the voice information. For example, if “Xiaoou” is used as the wake-up word, when the electronic device matches that the voice spoken by the user contains “Xiaoou”, the voice information behind the “Xiaoou” wake-up word is obtained, and the voice information in the voice information is extracted. Voiceprint features and command information to facilitate later analysis.

The instruction information may be some voice instructions composed of a user's natural language, such as "play an unread short message of sender A". The voice instruction is used to instruct the electronic device to acquire and play the unread short message of the sender A.

In some embodiments, in order to realize the extraction of the instruction information, the voice information may be converted into content information (such as text information) that the electronic device can understand, and then the content information is matched with a plurality of pre-stored instructions, and the matching is only successful The contents are used as instruction information. Of course, the instruction may be formulated according to user needs, and this application is not limited here.

102. Determine a current voiceprint matching threshold, where the voiceprint matching threshold is related to a device connection state of the electronic device.

Before matching voiceprint features in the voice information, a voiceprint matching threshold needs to be obtained. The voiceprint matching threshold is used to determine a matching degree between a voiceprint feature in the voice information and a voiceprint feature of a preset user, so that whether the voiceprint feature is a preset voiceprint feature can be determined through the matching degree.

The voiceprint matching threshold may be obtained from a specific address of the system, or may be obtained from a server.

The voiceprint matching threshold is related to the device connection status of the electronic device. Specifically, the electronic device may correspondingly adjust the voiceprint matching threshold according to the connection with other devices.

In some embodiments, the voiceprint matching threshold may determine two or more different voiceprint matching thresholds after determining the device connection status of the electronic device, and then use different voiceprint matching according to the device connection status of the electronic device. The threshold; or, adjusting the initial voiceprint matching threshold according to the current position, for example, increasing or lowering the voiceprint matching threshold.

In some embodiments, determining the current voiceprint matching threshold may include the following steps:

Acquire the current device connection status of the electronic device, and the device connection status is used to prompt the connection status between the electronic device and the target device; and adjust the voiceprint matching threshold according to the device connection status.

The target device is a device that meets a preset condition. The preset condition may include a connected device or a device that has stored configuration information in the system. Specific conditions can be determined according to the actual situation. The target device may be a smart bracelet, a smart watch, or another smart device.

Wherein, obtaining the current device connection status of the electronic device can be obtained by accessing a position related to the target device connection status in the system of the electronic device. For example, if the target device is connected to the electronic device via Bluetooth, the connection status of the Bluetooth device in the electronic device can be accessed, and related status attributes can be obtained from the connection status of the Bluetooth device, thereby obtaining the current device connection status of the electronic device. Of course, if the target device is connected to the electronic device through other methods, such as the WIFI hotspot method, the current device connection status of the electronic device can also be obtained from the location related to the connection method, the specific device connection method or the acquisition method. Applications are not limited here.

By obtaining the device connection status between the electronic device and other devices, it can be determined whether the user is near the electronic device, and thus the environmental condition of the electronic device can be determined.

If other devices carried by the user are connected to the electronic device, or the signal strength of the connection is strong, the user is located near the electronic device, and at this time, the electronic device can be judged to be in a safer environment. You can lower the voiceprint matching threshold, or maintain a low initial voiceprint matching threshold.

If other devices carried by the user are disconnected from the electronic device, it means that the user is not near the electronic device. At this time, it can be judged that the electronic device may be left unattended, the environment is less safe, and the voiceprint can be raised. Match threshold or maintain a high initial voiceprint match threshold.

103. Determine whether a matching degree between a voiceprint feature in the voice information and a preset user's voiceprint feature is greater than or equal to a voiceprint matching threshold. If yes, control the electronic device to perform a corresponding operation according to the content of the instruction information; if not, end this step.

In order to determine the identity of the user, the electronic device may store the voiceprint characteristics of the user in advance.

In some embodiments, a voiceprint feature comparison algorithm known to those skilled in the art may be used to process and compare the acquired voiceprint feature with the voiceprint feature of a pre-stored user to obtain a match between the two. Degree, and then compare the matching degree with the voiceprint matching threshold to determine whether it is greater than or equal to the voiceprint matching threshold.

If there are multiple pre-stored users, one-to-one matching can be used to obtain multiple matching degrees between the voiceprint features in the voice information and multiple preset users, so as to determine whether there is a match among the multiple preset users. A preset user whose degree is higher than the voiceprint matching threshold. If so, it can be determined that the user corresponding to the voice information is the preset user.

If the voiceprint features in a user's voice information do not match the pre-stored voiceprint features, it is determined that the user is not a preset user, and the subsequent adjustment steps may not be responded, so that users who do not meet the requirements cannot use voice information Electronic equipment is operated to improve the safety of electronic equipment.

104. If yes, control the electronic device to perform a corresponding operation according to the content of the instruction information.

The instruction information is information that can be read by the electronic device after being extracted from the voice information, and the electronic device can determine what operation needs to be performed according to the instruction information.

This operation may be playing preset audio, displaying preset information, etc., or opening a preset application, executing a preset function, or adjusting a system option, etc., which are not limited in the embodiment of the present application.

With reference to FIG. 2, an application scenario of an electronic device control method according to an embodiment of the present application is shown in the figure.

As shown in FIG. 2, for example, the user shouts “Xiaoou Xiaoou, where are you?” On “Location A”, and then the electronic device located at “Location B” can obtain the above-mentioned voice information through the microphone.

At this time, the content of the instruction information is "Where are you?" The electronic device first retrieves the data mapping related to the instruction information in the database, where each data mapping includes the mapping between the instruction information and the execution instruction relationship. Then, match the "where are you" instruction information with these data mappings in the database to obtain the corresponding execution instructions after the match, such as the execution "play where corresponding to" where are you "to guide the user to find the electronic Device's audio file ". The electronic device can then play the audio file according to this execution instruction.

In combination with the above embodiment, in the application scenario corresponding to the above embodiment, if the user needs to find the position of the electronic device, he can shout "Little Europe, Little Europe, where are you?" Then, the electronic device uses the microphone to obtain the user's voice information and detects that it contains the wake-up word "Xiaoou Xiaoou". At this time, the steps of extracting the voiceprint features and the instruction information in the voice information will continue.

In the process of extracting information or after extracting the information, the electronic device first determines the device connection status with other devices, so as to determine whether the user is near the electronic device according to the device connection status. For example, if the user's smart bracelet is connected to the electronic device at this time, and the signal strength of the connected state is large, it means that the user is near the electronic device, and if the initial voiceprint matching threshold is 90%, then You can reduce the voiceprint matching threshold to 70% and use 70% as the current voiceprint matching threshold.

After the voiceprint matching threshold is determined, the voiceprint characteristics in the voice information are matched with the voiceprint characteristics of the preset user, so that whether the user is a preset user is determined according to the voiceprint matching threshold.

If it is determined to be a preset user, the execution instruction to be executed by the electronic device is determined according to the instruction information, such as the execution instruction mapped to the instruction information "where are you" to play an audio file for guiding the user to find the electronic device.

It can be understood that the foregoing embodiments are only one of the implementations of this application, and other implementation manners can also be applied according to actual conditions.

For example, if the target device is connected to the electronic device via Bluetooth, the connection status of the Bluetooth device in the electronic device can be accessed, and related status attributes can be obtained from the connection status of the Bluetooth device, thereby obtaining the current device connection status of the electronic device. Of course, if the target device is connected to the electronic device through other methods, such as the WIFI hotspot method, the current device connection status of the electronic device can also be obtained from the location related to the connection method, the specific device connection method or the acquisition method. Applications are not limited here.
