Abstract

La présente invention a pour objet d'utiliser efficacement la voix ou le thème de contenu de conversation d'un ou plusieurs locuteurs. Un mode de réalisation comporte une unité de réception servant à recevoir des données de voix produites par un ou plusieurs utilisateurs, et un unité de traitement servant à exécuter un traitement en utilisant une première norme, lorsque l'ampleur d'une section catégorisée par la première norme parmi une pluralité de sections comprises dans les données de voix dépasse un seuil. De plus, l'unité de traitement exécute un traitement en utilisant une deuxième norme lorsque l'ampleur d'une section catégorisée par la deuxième norme parmi la pluralité de sections comprises dans les données de voix dépasse un seuil.
