Claim 4:
5. The method according to claim 2, wherein the constructing a supervised training loss function to pre-train the encoding model and the extraction model according to the labeled audio of the first audio, the embedding feature of the first audio, and the abstract feature of the target audio comprised in the first audio comprises:
determining a spectrum mask of the target audio comprised in the first audio according to the embedding feature of the first audio and the abstract feature of the target audio comprised in the first audio;
reconstructing the target audio based on the spectrum mask; and
constructing the supervised training loss function to pre-train the encoding model and the extraction model according to a difference between the reconstructed target audio and the labeled audio of the first audio.
