Abstract
In this paper, we present a study on the influence of the ex-pressivity on the articulation degree. It is part of a project that aims to transform the expressivity of an utterance for artistic purposes, such as cinema, theater and contemporary music. An algorithm for formant frequency estimation is presented. Then a measurement of the articulation degree is proposed involving a joint statistical analysis of the vocalic triangle area and of the speech rate. The application of this measurement to an ex-pressive French database, shows that the articulation degree de-pends on expressivity. Using Lindblom’s theoretical framework, we have tried to relate this articulation degree to the activation degree of a dimensional representation of emotions. Finally, speech processing is used to modify the articulation degree of a spoken or synthesized neutral utterance in order to apply a given expressivity to it. 1.
