Executive Summary

Perceived speech quality, or Quality of Experience (QoE), is the key criteria for evaluating VoIP service. Most of the existing solutions are intrusive, in a sense where they require both the original and the transmitted audio sequences. These solutions give good estimation of the QoE, but they cannot be used in real-time. In fact, Service Provider and Network Provider are highly interested on automatic QoE estimation tool (without intrusion) in order to monitor and control the perceived quality of their VoIP service. In this paper, the authors present a new perceived speech quality estimation tool, named ALICANTE Pseudo Subjective Quality Assessment (A-PSQA) for two widely VoIP codecs, iLBC and Speex.
