Claim 18:
19. A non-transitory computer-readable storage medium storing computer program instructions executable by at least one processor to perform:
determining a historical voice frame corresponding to a target voice frame;
determining a frequency-domain characteristic of the historical voice frame;
invoking a network model to predict the frequency-domain characteristic of the historical voice frame, to obtain a parameter set of the target voice frame, the parameter set including a plurality of types of parameters, the network model including a first neural network (NN) and a plurality of second NNs, and invoking the network model comprising:
invoking the first NN to predict the frequency-domain characteristic of the historical voice frame, to obtain a virtual frequency-domain characteristic of the target voice frame;
invoking the second NNs to predict the virtual frequency-domain characteristic of the target voice frame, to obtain parameters corresponding to the second NNs; and
establishing the parameter set of the target voice frame according to the parameters respectively corresponding to the plurality of second NNs; and reconstructing the target voice frame according to the parameter set.
