Title:
AUDIO PACKET LOSS COMPENSATION PROCESSING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/143364
Kind Code:
A1
Abstract:
An audio packet loss compensation processing method and apparatus, and an electronic device. The method comprises: acquiring time-domain signals of a first number of existing audio frames in the past (S101); performing acoustic feature extraction on the time-domain signals of the first number of existing audio frames, so as to generate acoustic features of the existing audio frames (S102); performing semantic feature extraction on the time-domain signals of the first number of existing audio frames, and performing semantic understanding on the basis of the extracted semantic features, so as to generate semantic expressions corresponding to the existing audio frames (S103); and according to the acoustic features and the semantic expressions, predicting a time-domain signal of the current audio frame for audio packet loss compensation (S104). During an audio frame prediction process, feature extraction is performed on an original timing signal of an audio frame, thereby avoiding information loss of audio features. In addition, during the audio frame prediction process, semantic understanding assistance is introduced, such that a lost audio frame can be predicted more accurately.
