| Abstract: | In packet-based real-time network,packet loss can not be avoided,which may greatly damage the speech quality.This paper proposed a main-sub speech codec method based on AMR for reducing influence of the packet loss.The simulation results show that the speech quality over the IP network was improved efficiently with the proposed method. |
