Abstract

The invention relates to a voice signal processing method, system and device, computer equipment and a storage medium. The method comprises the steps of: enabling an encoder to obtain a voice residualsignal from an original voice signal, and then carrying out shunting on the voice residual signal to obtain a plurality of sub-voice residual signals; acquiring compensation information of each sub-voice residual signal based on preset compensation configuration; and then sending a code stream comprising each sub-voice residual signal and the corresponding compensation information to a decoder, wherein the code stream is used for indicating the decoder to decode according to each sub-voice residual signal and the corresponding compensation information. According to the method, the packet lossresistance of the voice encoder can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of audio and video coding and decoding, and in particular to a voice signal processing method, system, device, computer equipment and storage medium. Background technique [0002] Current speech encoders generally use parametric coding, that is, according to the human vocalization model, the speech signal is converted into channel parameters and excitation parameters, quantized and encoded to generate a code stream, and then the code stream is sent to the channel for transmission. After receiving the code stream, the receiver decodes the channel parameters and excitation parameters, and then re-synthesizes the speech signal according to the vocalization model. [0003] In practical applications, packet loss often occurs when transmitting code streams. Based on this reality, people have developed many anti-packet loss strategies, which are mainly divided into two categories. One is transmission-ori...
