Zusammenfassung | In this contribution, we present the processing and the validation of exemplary listing material for the degradations covered by the P.TCA methodology. The processing was conducted with the help of two speech and signal processing tools. Seven experts subsequently annotated the speech files of a created database following the processing chain according to the draft instructions. The annotations are analysed with respect to their frequency and accuracy of the created exemplary listening material. The contribution is meant as an initial step, to show that the processing of exemplary listening material for the P.TCA methodology is generally possible and it allows further findings about the improvement of the P.TCA methodology. |
