IP和ATM网络中语音分组丢弃对解码语音质量的影响及对应的措施

The influence of lost speech packets on the speech quality in IP and ATM networks and improvement measures

基于分组传输的网络(如IP和ATM),进行实时语音通信时,存在分组可能丢失,因而影响通信质量的问题。本文提出两种新的方法,以减少或降低语音分组丢失带来的影响。实验结果表明,它们明显改善了语音通信质量。

In packet-based networks such as IP and ATM networks, lost speech packets may greatly damage the speech quality. This paper presents two new methods for the purpose of reducing the influence of lost speech packets on the speech communication quality. Experiments prove that they evidently improve the speech communication QoS.
