Résumé

La reconnaissance automatique de mots isolés par anamorphose temporelle (ou DTW) est un outil adéquat lorsque les mots dictés se distinguent facilement les uns des autres. Par contre, lorsque ces mots sont tirés d’une base de données à haut niveau de difficulté, où les mots sont acoustiquement semblables, un algorithme spécifique doit être employé pour faciliter la tâche. L’alphabet français est un vocabulaire qui se compose de lettres similaires que l’on peut regrouper en 6 classes distinctes.
