Abstract In this contribution the frequency and consistency of expert and naive listeners in a technical causes annotation experiment are compared. For this, two experiments with experts and naifs following the guidelines of the currently discussed ITU-Recommendation P.TCA were conducted. In these experiments, participants are asked to annotate speech files with respect to their possible degradation by choosing from a list of 47 degradations, separated in 9 impairment types. Originally intended for experts, the P.TCA procedure was expanded with exemplary listening material for naive annotators to lift them on an expert level. The results show that experts annotate more consistent than naifs and that the additional provided examples are not sufficient for an equal analysis. Furthermore, findings about possible improvement of the P.TCA methodology are presented.
