The kernel layer processes touch operations into original input events (including touch coordinates, time stamps of touch operations, and other information). Raw input events are stored at the kernel level. The application framework layer obtains the original input event from the kernel layer, and identifies the control corresponding to the input event.

It should be noted that there is no limitation on whether each electronic device in the voiceprint authentication response system is in an offline state (that is, a power-off state) or in a non-offline state (that is, a power-on state).

Next, with reference to FIG. 4 , a schematic diagram of the hardware and software structure of each electronic device in the voiceprint authentication response system is introduced.

Please refer to FIG. 4 . FIG. 4 is a schematic diagram of the software and hardware structure of each electronic device in the voiceprint authentication response system shown in FIG. 3 . As shown in Figure 4, for each electronic device in the voiceprint authentication response system, the hardware and software structure of each electronic device may include: an audio processing module, an authentication word collection module, a voiceprint authentication module, and a voiceprint registration module And authentication result consistency module. Wherein, the aforementioned modules may use software codes and/or hardware components to implement corresponding functions of the modules.

The voiceprint registration module is used to receive the user's voice registration data, perform voiceprint training on the user's voice registration data, and generate the user's voiceprint authentication model.

Among them, the voice registration data can be the voiceprint data obtained by the user reading aloud the text-related and irrelevant content prompted by the electronic device, or it can be the user's voiceprint data imported by the user based on the user interface design (UI) of the electronic device. Voiceprint data, which is not limited in this application. The user's voiceprint authentication model is obtained based on the user's voice registration data, and can output the authentication score of the electronic device by analyzing the user's voice interaction data such as physical oral features such as sound quality, sound length, and sound.

Among them, the authentication score of the electronic device is used to indicate the matching degree of the electronic device authentication voice interaction data belonging to the user, which can represent the closer the physical oral characteristics of the voice interaction data such as sound quality, sound length, and sound in the voiceprint authentication are to the user's physical oral cavity. feature. That is, the higher the authentication score of the electronic device is, the higher the degree of matching that the voice interaction data of the electronic device authenticates the user belongs to the user. The present application does not limit the specific implementation manner of the authentication score of the electronic device. In addition, the electronic device may store the authentication score of the electronic device in the form of a key-value.

The voiceprint registration module is further configured to store the user's voiceprint authentication model in the electronic device, so that the electronic device uses the user's voiceprint authentication model to perform voiceprint authentication on the voice interaction data. It should be noted that the electronic device may store voiceprint authentication modules of one or more users. In addition, the electronic device can also optimize or update a user's voiceprint authentication module.

The audio processing module is used to receive the user's voice interaction data. Since the user's voice interaction data will inevitably be mixed with ambient sound data, the audio processing module is also used to perform noise reduction processing, acoustic-electric conversion, and format matching on the user's voice interaction data to obtain the processed data, and Send the processed data to the authentication word collection module. Wherein, the processed data may adopt a format such as pulse code modulation (pulse code modulation, PCM).

The authentication word collection module is used to cut the processed data to obtain the user's voice interaction data, and send the user's voice interaction data to the voiceprint authentication module.

The voiceprint authentication module is used to perform voiceprint authentication on the user's voice interaction data through the user's voiceprint authentication module, obtain the authentication score of the electronic device, and send the authentication score of the electronic device to the authentication result consistency module.

The authentication result consistency module is used to receive the respective authentication scores of the other electronic devices except the electronic devices in the voiceprint authentication response system. Therefore, the electronic device can obtain the respective authentication scores of all electronic devices in the voiceprint authentication response system. In addition, the electronic device may store the respective authentication scores of other electronic devices in the form of a key-value.

In some embodiments, the authentication result consistency module can send the authentication score of the electronic device to the rest of the electronic devices in the voiceprint authentication response system except the electronic device through the epidemic protocol (gossip protocol), that is, the electronic device's The authentication score is propagated to the rest of the electronic devices that communicate and interconnect with the electronic device, and receive the respective authentication scores of the rest of the electronic devices sent by the other electronic devices in the voiceprint authentication response system except the electronic device, that is, wait to receive the transmission of the rest of the electronic devices. The respective authentication scores of the rest of the electronic devices, so that the electronic devices can receive the respective authentication scores of the rest of the electronic devices in the voiceprint authentication response system except the electronic devices.

The authentication result consistency module is also used to determine whether the electronic device itself is an answering electronic device based on the respective authentication scores of all electronic devices in the voiceprint authentication response system, that is, whether the electronic device needs to perform an authentication response to the user's voice interaction data.

Next, with reference to FIG. 5A-FIG. 5C , the detailed implementation process of synchronizing the authentication scores of all electronic devices by the authentication result consistency module is introduced.

Please refer to FIG. 5A-FIG. 5C and FIG. 6. FIG. 5A-FIG. 5C is a schematic flow diagram of the authentication result consistency module in the electronic device shown in FIG. 4 synchronizing the authentication scores of all electronic devices. FIG. 6 is an embodiment of the present application A schematic diagram of a scenario of a voiceprint authentication response system is provided.

For the sake of illustration, in Fig. 5A-Fig. 5C and Fig. 6, the voiceprint authentication response system includes: speakers, large screens, tablets, mobile phones and PCs, and the scene of multiple electronic devices is a home scene as an example. Among them, speakers can be regarded as node A, large screens can be regarded as node B, tablets can be regarded as node C, mobile phones can be regarded as node D, and PCs can be regarded as node E. In addition, node A communicates with node B and node C respectively, and node C communicates with node D and node E respectively.

As shown in Figure 5A, after node A has determined the certification score of the speaker, set node A as the source of transmitting the certification score of the speaker, and set node A to include two transmission paths, that is, node A can communicate with A Node B and C nodes communicate with each other to spread the authentication score of the speakers. It should be noted that, except for the number 2, the present application does not limit the number of propagation paths of the A node. In addition, the propagation complexity of node A is: O(Log5)(base2).

After node A completes the dissemination of the speaker's authentication score, nodes B and C will be "propagated", that is, node B and node C have received the speaker's authentication score.

In the process of disseminating the authentication scores of the speakers next time, each of the nodes A, B and C includes two propagation paths. At this time, the node C can respectively propagate the certification score of the speaker to the node D and the node E which are communicatively interconnected with the node C.

After the C node completes the dissemination of the speaker's certification score, the D node and the E node will be "propagated", that is, the D node and the E node have received the speaker's certification score.

To sum up, the authentication score of the speaker has been transmitted to all nodes (namely node A, node B, node C, node D and node E), that is, all electronic devices in the voiceprint authentication response system have received the authentication score of the speaker.

It should be noted that, in addition to disseminating the authentication score of the electronic device, each electronic device in the voiceprint authentication response system may also disseminate the device identification of the electronic device. Wherein, the device identifier of the electronic device is used to uniquely identify the electronic device corresponding to the authentication score of the electronic device. The present application does not limit the specific implementation manner of the device identification of the electronic device. For example, the device identifier of the electronic device may be represented by means of an ID card identification number (identity document, ID), a device model, or a device number.

In addition, after receiving the authentication score of the electronic device, since there may be electronic devices in the voiceprint authentication response system that are offline, the rest of the electronic devices in the voiceprint authentication response system can send the received electronic device information to the electronic device. The notification message of the authentication score enables the electronic device to know that other electronic devices have received the authentication score of the electronic device.

Similarly, except for the speakers, other electronic devices in the voiceprint authentication response system can use the above method to propagate their respective authentication scores to all electronic devices. Furthermore, each electronic device in the voiceprint authentication response system has already known the respective authentication scores of all electronic devices, that is, each electronic device in the non-offline state has received the respective authentication scores of all the electronic devices in the non-offline state .

Therefore, the authentication result consistency module in each electronic device can determine whether the electronic device itself is the responding electronic device based on the respective authentication scores of all electronic devices.

In some embodiments, the authentication result consistency module can determine the highest authentication score among the respective authentication scores of all electronic devices in the voiceprint authentication response system.

When the electronic device corresponding to the highest authentication score includes an electronic device in the voiceprint authentication response system, the authentication result consistency module may determine the electronic device corresponding to the highest authentication score as the responding electronic device.

For example, assuming that the mobile phone and the PC are offline, the speaker, the large screen and the tablet have all received: the authentication score of the speaker is 90, the authentication score of the large screen is 80, and the authentication score of the tablet is 85. Well, since 90>85>80. Therefore, the authentication result consistency module of each electronic device in the speaker, the large screen and the tablet can select the responding electronic device as the speaker.

In addition, the authentication result consistency module is also used to measure the distance between the electronic device and the user when the user sends out the user's voice interaction data. Alternatively, each electronic device may add a ranging module (not shown in FIG. 4 ) for measuring the distance between the electronic device and the user when the user sends out the user's voice interaction data. Wherein, the ranging module may use software codes and/or hardware components to realize the ranging function.

When the electronic device corresponding to the highest authentication score includes multiple electronic devices in the voiceprint authentication response system, the authentication result consistency module can determine the electronic device closest to the user from the electronic devices corresponding to the highest authentication score, and compare it with the The electronic device closest to the user is determined to be the answering electronic device.

For example, assuming that the mobile phone and the PC are offline, the speaker, the large screen and the tablet have all received: the authentication score of the speaker is 90, the authentication score of the large screen is 90, and the authentication score of the tablet is 85. Then, because 90>85, and the speaker is closer to the user than the big screen. Therefore, the authentication result consistency module of each electronic device in the speaker, the large screen and the tablet can select the responding electronic device as the speaker.
