Abstract
Rapid growth in the deployment of VoIP applications increases the need for assessing quality of voice communication. The end users expect the same quality of service as traditional telephone system, which is circuit switched. Since the network is originally designed for data communication, VoIP users experience degradation in voice quality due to factors like latency, jitter, packet loss, bandwidth etc. So it is important to conceal the packet loss, so that the end users can experience high quality communication. In this paper we propose a receiver- based packet loss concealment mechanism by predicting the jitter buffer delay using Adaptive Neuro-Fuzzy Inference System (ANFIS) model.
