Abstract

La présente invention concerne un procédé et un dispositif de séparation d'appel vocal dans un dispositif portatif. Lorsqu'un appel vocal se produit, un module de commutation évalue tout d'abord si la fonction de séparation d'appel vocal est démarrée ; lorsqu'un commutateur est dans un état ouvert, la séparation audio est requise, autrement, aucun traitement n'est fourni. Un module de jugement évalue si un Bluetooth actuel est dans un état de connexion et, si un dispositif d'oreillette Bluetooth est dans un état de connexion, le traitement s'effectue en continu ; autrement, aucun traitement n'est fourni. Un module de commutation invoque une interface de séparation, afin de réaliser la séparation vocale ; et, après la séparation, un appel Bluetooth peut être réalisé sous séparation vocale. L'invention présente les avantages suivants : les utilisateurs peuvent utiliser commodément un appel Bluetooth pendant une période prolongée et un dispositif Bluetooth n'ayant qu'une fonction d'écoute peut réaliser l'appel par séparation audio, de sorte que le volume de l'oreillette Bluetooth soit largement réduit et, en outre, l'influence sur le confort du corps humain est réduite.
