Abstract
A packet-layer quality assessment system is proposed to monitor the quality of VoIP service in this paper. The proposed system is composed of three modules, where the quality assessment module evaluates the voice quality in terms of the information extracted by the packet header analysis module and silence detection module. It is noteworthy that the voiced segments and silence segments in the voice streaming are distinguished and treated differently in the evaluation of voice quality. Taking adaptive multi-rate (AMR) encoded stream over RTP/UDP/IP (Real-time Transport Protocol/ User Datagram Protocol/Internet Protocol) as an example, the process of the voice quality assessment employing the proposed system is described in detail. Experimental results reveal that the estimation model in the proposed system achieves superior performance over the compared models.
