Le procédé consiste à : collecter des données d'un signal vocal émis par un dispositif haut-parleur d'un terminal courant, et obtenir une valeur d'intensité sonore de la voix courante ; et comparer cette valeur d'intensité sonore de la voix courante avec une valeur d'intensité sonore de voix prédéfinie, et régler la valeur de volume courant selon le résultat de la comparaison. L'invention concerne également un dispositif de réglage de volume automatique. L'utilisation du procédé et du dispositif de réglage automatique de volume dans des modes de réalisation de la présente invention permet d'éviter les variations d'intensité sonore de voix lorsque l'on passe d'une source vocale à une autre, de régler automatiquement le volume et d'améliorer l'expérience de l'utilisateur.
