Zusammenfassung In this contribution, we present an approach for a ``ground-truth'' overview of a commonly used database in P.TCA annotation experiments. The overview is created according to descriptions of the used conditions and the annotation frequency of experts and na"ive listeners. The overview is targeted to provide a basis for future experiments and to give useful information about the reliability of the P.TCA schema and possible future steps. Additionally, we provide new information about the processing of exemplary listening material.
