In the following paper the influence of a telephony speech quality on the automated speaker recognition system (ASRS) performance is presented. The speech quality in VoWLAN, GSM and PSTN was objectively measured using Perceptual Evaluation of Speech Quality method (PESQ). The correlations between speech quality degradations measured as PESQ Mean Option Score (MOS) and ASRS error rates of this evaluation are presented by means of detection error tradeoff (DET) curves. The results show the correlations between MOS and ASRS equal error rate (EER) and promise the objective speech quality measurements can be used in the prediction of ASRS performance.
