In this study three different prominence and speech melody related effects on voice quality were studied using an inverse filtering based method. The hypothesis that prominence as a function of sentence and word stress is signaled with more pressed voice quality was tested. The results indicated discrepancies in the parameterization results, and the original hypothesis could not be confirmed. Instead, it is suggested that prominence is expressed with a more breathy voice quality. A possible physiological explanation for the phenomenon is also provided.
