Claim 1:
2. The method of claim 1, wherein determining the target phase signal according to whether the variable-speed rate of the current audio frame is the same as the variable-speed rate of the previous audio frame comprises:
obtaining a candidate phase signal of the current audio frame according to the variable-speed rate of the previous audio frame;
in a case where the variable-speed rate of the current audio frame is the same as the variable-speed rate of the previous audio frame, determining the candidate phase signal as the target phase signal of the current audio frame; and
in a case where the variable-speed rate of the current audio frame is different from the variable-speed rate of the previous audio frame, determining a compensation phase signal according to the variable-speed rate of the current audio frame and the candidate phase signal, determining the target phase signal of the current audio frame based on the compensation phase signal, and updating a target phase signal of a set number of audio frames before the current audio frame.
