Further, the second mobile terminal may be a parent's mobile terminal, the first mobile terminal may be a child's mobile terminal, and the use of the target function module in the first mobile terminal can only be realized after the operation of the second mobile terminal, see the description below for details.

Before step S101, the target function module in the first mobile terminal may be that the second user preliminarily sets permissions on some function modules (such as video applications, payment applications, game applications, etc.) in the first mobile terminal, so that the first user These functional modules in the mobile terminal cannot be used.

S102. The server sends a permission release request for releasing the permission of the target function module to the second mobile terminal;

Specifically, the second mobile terminal is a pre-bound mobile terminal of the first mobile terminal; that is, the first mobile terminal and the second mobile terminal are pre-bound on the server.

S103. The server receives the second voice sent by the second mobile terminal, where the second voice is input by the second user after the second mobile terminal receives the authorization release request;

S104. The server converts the first speech into a first sound signal, and converts the second speech into a second sound signal;

S105. The server synthesizes the first sound signal and the second sound signal to obtain a verification sound signal;

S106. The server judges whether the verification sound signal matches the pre-stored default sound signal. If it matches, it confirms that the verification is successful, and sends verification success information to the first mobile terminal, so that the first mobile terminal cancels the authority of the target function module.

Further, the verification success information includes the duration information that allows the first mobile terminal to release the authority of the target function module, so that after the first user connects the wrong authority of the target function module, the duration of use is only for the release target The duration information of the permission of the functional module, after reaching the duration information, the permission setting of the target functional module is restored, and the first user is restricted from using the target functional module.

Further, the method also includes:

The server receives a control instruction sent by the second mobile terminal for controlling the first mobile terminal to restore the authority of the target function module;

The server sends a locking instruction to the first mobile terminal, so that the first mobile terminal restores the authority of the target function module and prohibits the first user from using the target function module.

Further, the server synthesizes the first sound signal and the second sound signal to obtain a verification sound signal, including:

The server determines an alignment point between the first sound signal and the second sound signal, the alignment point being a position where the first sound signal and the second sound signal begin to match, in other words , if two audio signals are to be synthesized, it is necessary to find out which audio frame to start synthesizing from, and this audio frame can be understood as an alignment point;

The server synthesizes the first sound signal and the second sound signal into a verification sound signal according to the alignment point.

Further, determining the alignment point between the first sound signal and the second sound signal by the server includes:

the server calculates a difference between the first duration and the second duration;

If the difference is less than or equal to the preset value, the shorter sound signal among the first sound signal and the second sound signal is periodically scaled, so that the first sound signal and the The final duration of the second sound signal is the same, and then the scaled first audio frame of the first sound signal and the first audio frame of the second sound signal are determined as alignment points.

Specifically, if the difference is less than or equal to the preset value, it means that the gap between the two sound signals is small when input. At this time, one of the sound signals can be periodically scaled, for example, for a long sound signal Periodic compression (also known as fast forward), and/or periodical amplification of short sound signals (also known as slow forward), so that the final duration of the two sound signals is the same, and then the two The first audio frame of the segment sound signal is used as the alignment point for alignment.

Among the second sound signals, the longer sound signals have the same length.

Specific examples:

The first duration is 1 second, the second duration is 1.1 seconds, then the ratio X is (1.1-1)/1=0.1, assuming that the first sound signal has 100 audio frames, then Y is 100, and the amplification factor Z is 0.1* (100/ (100-1)) = 0.101, then the other 99 audio frames except the first audio frame are amplified in time according to the amplification factor of 0.101, and the enlarged 100 audio frames have 1.1 seconds It's been a long time.

Further, if the difference is greater than the preset value, it means that the gap between the two sound signals is relatively large when they are input. If one of the sound signals is still periodically scaled at this time, the scaling will cause serious problems.
