Abstract
Dans cet article, nous nous intéressons à la tâche de détection de thème dans le cadre de la reconnaissance automatique de la parole. La combinaison de plusieurs méthodes de détection montre ses limites, avec des performances de 93.1 %. Ces performances nous mènent à remettre en cause le thème de référence des paragraphes de notre corpus. Nous avons ainsi effectué une étude sur la fiabilité de ces références, en utilisant notamment les mesures Kappa et erreur de Bayes. Nous avons ainsi pu montrer que les étiquettes thématiques des paragraphes du corpus de test comportaient vraisemblablement des erreurs, les performances de détection de thème obtenues doivent donc êtres exploitées prudemment.
