Zusammenfassung In this contribution, we present a graphical-user-interface for the annotation process of the P.TCA schema. Using available exemplary listening material, an annotation experiment following the P.TCA guidelines was conducted with na"ive listeners. The annotations are analysed with respect to their frequency and accuracy in comparison to expert listeners. Further findings about the improvement of the P.TCA methodology are presented.
