Abstract

Il est décrit un procédé permettant de reconnaître la vitesse d'échantillonnage de données vocales pures, ainsi que son appareil et système. Le procédé consiste : à exécuter une transformée de Fourier sur des données vocales pures de manière à obtenir des données d'un domaine fréquentiel; selon les données de seuil antérieures reçues, à traiter les données du domaine fréquentiel de manière à obtenir des informations de bande de fréquence; à acquérir des points de fréquence de coupure haute fréquence des informations de bande de fréquence, et, selon des vitesses d'échantillonnage différentes prédéterminées, à calculer des fréquences postulées correspondant aux points de fréquence de coupure haute fréquence; et à comparer les fréquences postulées à une fréquence reçue, ainsi qu’à prélever la vitesse d’échantillonnage correspondant à la fréquence postulée avec un résultat le plus similaire à une vitesse d’échantillonnage réelle.
