Contribution à la synthèse de parole par modèle physique. Application à l'étude des voix pathologiques

Abstract : The goal of physical modelling of speech is to understand and reproduce the physical phenomena occuring during phonation. This thesis is mainly focused on the modelling of both the glottal airflow and the vocal-folds mechanics. This study is based on several experimental set-up reproducing physical phenomena contributing to the vocal folds self-oscillations. Theoretical models describing both the mechanics of the folds and the hydrodynamics of the glottal airflow are presented and compared to experimental results. A particular attention is paid on the physical modelling of pathological vocal folds. An experimental study of the airflow through in-vitro pathological vocal folds is first presented. Then, measurements carried out on a new experimental set-up simulating self-oscillations of pathological vocal-folds are analysed with a temporal simulation code.
