Abstract

Le système comprend une mémoire (24) de texte contenant sous forme d'informations numériques un texte de lecture donné avec des indicateurs à une pluralité d'emplacements dans le texte, et une mémoire audio (22) contenant sous forme d'informations numériques des paroles préenregistrées correspondant au texte en question et ayant des indicateurs à une pluralité d'emplacements de paroles correspondant à la pluralité d'emplacements dans le texte. Un processeur central (26) est associé à la mémoire audio et la mémoire de texte pour établir une correspondance entre les indicateurs de paroles et les indicateurs du texte, pour que chaque emplacement dans le texte et son emplacement de paroles respectif soient adressables d'une manière sensiblement simultanée. Un processeur audio (32) associé au processeur principal traite les informations numériques de la mémoire audio et fournit une sortie correspondant à la reproduction des paroles préenregistrées. Une unité audio (36) permet à l'utilisateur d'écouter le texte lu. Un dispositif de commande (30) de la vitesse associé au processeur audio commande la vitesse à laquelle le texte est reproduit. Le processeur audio maintient, lors de la lecture, la même hauteur de son que celle des paroles préenregistrées.
