Abstract

Un mode de réalisation de la présente invention concerne un procédé et un terminal de commutation de mode d'appel. Le procédé comprend : l'établissement d'une connexion d'appel entre un premier terminal connecté ayant un casque d'écoute périphérique et un dispositif distant; la collecte, par le premier terminal, d'un premier signal sonore au moyen d'un microphone du casque d'écoute périphérique; la conversion, par le premier terminal, du premier signal sonore collecté en premières données audio; la détermination, par le premier terminal, des premières données audio comme étant des données valides ou non; la réalisation d'une commutation, par le premier terminal, de façon à collecter un second signal sonore au moyen d'un microphone du premier terminal si les premières données audio sont des données invalides. Ainsi, le terminal peut déterminer automatiquement quel mode d'appel doit être utilisé en fonction de situations réelles, empêchant ainsi l'appel d'être coupé par erreur tout en éliminant également des étapes d'opérations manuelles d'un utilisateur.
