Abstract
A method for audio packet loss compensation processing includes: acquiring time domain signals of a first number of existing audio frames in a case that an audio packet loss occurs; carrying out acoustic feature extraction on the time domain signals of the first number of the existing audio frames to generate acoustic features of the existing audio frames; carrying out semantic feature extraction on the time domain signals of the first number of the existing audio frames, and carrying out semantic understanding based on the extracted semantic features to generate semantic expressions corresponding to the existing audio frames; and predicting a time domain signal of a current audio frame according to the acoustic features and the semantic expressions, for audio packet loss compensation.
