摘要

在基于分组传输的实时网络语音通信中

分组丢失不可避免

这也造成了语音质量的恶化.本文提出了一种基于AMR的主次型语音编解码方法

可以有效减少分组丢失对语音质量的影响.仿真实验证明

这种方法明显改善了IP网络语音通信的质量.

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.
