Abstract

Cette invention propose un programme de recherche d'informations audio qui peut obtenir un résultat de recherche précis et peut être facilement utilisé dans diverses bases de donnés. Un programme de recherche d'informations audio amène un ordinateur à exécuter au moins les étapes suivantes : la conversion d'un élément audio enregistré dans des informations audio en une chaîne de caractères, la mesure du temps de reproduction des informations audio, l'enregistrement de la chaîne de caractères des informations audio dans une base de données par la division de la chaîne en un intervalle de temps prédéterminé si le temps de reproduction des informations audio est plus long que le temps prédéterminé et par l'enregistrement de la chaîne de caractères des informations audio dans la base de données sans la diviser si le temps de reproduction des informations audio n'est pas plus long que le temps prédéterminé, la décision d'un objet de recherche pour rechercher la base de données et une condition de recherche pour l'objet de recherche, l'exécution d'une recherche de la base de données conformément à la condition de recherche, et l'émission du résultat de recherche.
