Abstract

L'objet de l'invention concerne un procédé pour affecter au moins une classe sonore à un signal sonore, caractérisé en ce qu'il comprend les étapes suivantes : diviser le signal sonore en des segments temporels présentant une durée déterminée; extraire les paramètres fréquentiels du signal sonore dans chacun des segments temporels, en déterminant une série des valeurs du spectre de fréquence dans une plage de fréquences comprise entre une fréquence minimale et une fréquence maximale; regrouper les paramètres fréquentiels dans des fenêtres temporelles présentant une durée déterminée supérieure à la durée des segments temporels; extraire de chaque fenêtre temporelle, des composantes caractéristiques; et en considération des composantes caractéristiques extraites et à l'aide d'un classificateur, identifier la classe sonore des fenêtres temporelles du signal sonore.
