Zusammenfassung In this contribution we address the evaluation of speech transmission quality by the full-reference models ITU-T Rec. P.862 (PESQ), ITU-T Rec. P.862.2 (WB extension of PESQ) and ITU-T Rec. P.863 (POLQA) using packet loss patterns generated by the ITU-T Rec. G.1050 network simulation tool. Special focus was put on conformance testing of quality assessment models according to ITU-T Rec. 564 and possible usage of the mentioned simulation tool in this case. A modification of network profiles predefined in G.1050 is proposed to reach different target quality levels. A number of PESQ and POLQA evaluations have been carried out which indicated possible usage of modified network profiles in P.564 conformance testing.
