Résumé

Après avoir étudié théoriquement la propagation du son dans un conduit vocal avec pertes, on décrit le simulateur mis au point. La méthode retenue permet d’obtenir la fonction de transfert, la valeur des fréquences des formants et les bandes passantes du conduit vocal. Le simulateur permet de déterminer la contribution des différentes sources de pertes au niveau des fréquences et des bandes passantes des formants.
