  abstract =     "Speech quality, as perceived by the users of Voice
                 over Internet Protocol (VoIP) telephony, is critically
                 important to the uptake of this service. VoIP quality
                 can be degraded by network layer problems (delay,
                 jitter, packet loss). This paper presents a method for
                 real-time, non-intrusive speech quality estimation for
                 VoIP that emulates the subjective listening quality
                 measures based on Mean Opinion Scores (MOS). MOS
                 provide the numerical indication of perceived quality
                 of speech. We employ a Genetic Programming based
                 symbolic regression approach to derive a speech quality
                 estimation model. Our results compare favourably with
                 the International Telecommunications
                 Union-Telecommunication Standardisation (ITU-T) PESQ
                 algorithm which is the most widely accepted standard
                 for speech quality estimation. Moreover, our model is
                 suitable for real-time speech quality estimation of
                 VoIP while PESQ is not. The performance of the proposed
                 model was also compared to the new ITU-T recommendation
                 P.563 for non-intrusive speech quality estimation and
                 an improved performance was observed.",
