Abstract

Procédé et appareil de recommandation de contenu. Le procédé comprend les étapes suivantes : un dispositif de réseau reçoit des informations vocales soumises par un utilisateur (S1) ; extrait des informations de caractéristiques vocales de l'utilisateur selon les informations vocales (S2) ; interroge une première base de données vocale prédéfinie selon les informations de caractéristiques vocales afin d'obtenir des premières données vocales appariées (S3) ; et recommande les premières données vocales à l'utilisateur (S4). La présente solution technique permet de recommander à un utilisateur des données vocales appariées, telles que des chansons et des clips vidéo, selon les informations de caractéristiques vocales de l'utilisateur. Dans les applications vocales interactives actuelles et émergentes, il est possible d'utiliser des procédés d'exploitation intéressants pour inciter les utilisateurs à utiliser automatiquement la voix, et à acquérir ainsi l'habitude d'utiliser la voix pour effectuer une recherche. Par exemple, sur la base des besoins sociaux et de divertissement du public actuel en matière de données vocales, diverses informations de caractéristiques vocales d'un utilisateur, telles que des données vocales et audio, sont analysées automatiquement lorsque l'utilisateur recherche de la musique ou utilise sa voix ; et des chansons appropriées pour une performance de chant, ou un chanteur approprié pour une imitation sont recommandés à l'utilisateur de manière appropriée au moyen d'une analyse vocale de mégadonnées.
