Describing Intonation with a Parametric Model

Gregor Möhler

University of Stuttgart, Germany

In this study a data-based approach to intonation modeling is presented. The model incorporates knowledge from intonation theories like the expected types of F0 movements and syllable anchoring. The knowledge is integrated into the model using an appropriate approximation function for F0 parametrization. The F0 parameters that result from the parametrization are predicted from a set of features using neural nets. The quality of the generated contours is assessed by means of numerical measures and perception tests. They show that the basic hypotheses about intonation description and modeling are in principle correct and that they have the potential to be successfully applied to speech synthesis. We argue for a clear interface with a linguistic description (using pitch-accent and boundary labels as input) and discourse structure (using pitch-range normalized F0 parameters).
