L’invention concerne un dispositif de sortie vocale qui peut changer automatiquement l’acoustique correspondant à un genre de contenu comprenant une sortie vocale à partir d’une partie de sortie. Le dispositif de sortie vocale comprend un élément de support (12) servant à supporter un panneau de réflexion (11), un dispositif d’entraînement (13, 16) qui est connecté à l’élément de support (12) et entraîne le tableau de réflexion (11) supporté par l’élément de support (12), et une unité de commande (20) servant à commander l’entraînement du dispositif d’entraînement (13, 16). Dans un moyen arithmétique qui constitue l’unité de commande (20), un programme est stocké. Il sert à exécuter une étape consistant à lire les informations de genre contenues dans un signal de contenu transmis à l’unité de commande (20), une étape consistant à acquérir des informations sur la commande acoustique à partir des informations de genre lues, en se référant à une table de commande de l’acoustique des informations de genre, les informations de genre et les informations sur la commande acoustique étant liées les unes aux autres, la table étant stockée dans un moyen de stockage (23) qui constitue l’unité de commande (20), et une étape consistant à commander le dispositif d’entraînement (13, 16) sur la base des informations acquises sur la commande acoustique.
