Claim 13:
14. The computer device according to claim 12, wherein the performing unsupervised training on the encoding model, the extraction model, and the estimation model according to the second audio, and adjusting model parameters of the extraction model and the estimation model comprises:
encoding an audio feature of the second audio through the encoding model, to obtain an embedding feature of the second audio;
extracting the embedding feature of the second audio through the extraction model, to obtain an abstract feature of the target audio comprised in the second audio;
processing the embedding feature of the second audio and the abstract feature of the target audio comprised in the second audio through the estimation model, to obtain a mutual information (MI) estimation feature between the second audio and the abstract feature of the target audio comprised in the second audio;
constructing an unsupervised training loss function according to the MI estimation feature; and
fixing the model parameter of the encoding model, and adjusting the model parameters of the extraction model and the estimation model according to a direction of minimizing the unsupervised training loss function.
