Title
(EN) MICROPHONE OPERATIONS BASED ON VOICE CHARACTERISTICS
(FR) FONCTIONNEMENT DE MICROPHONES SE BASANT SUR DES CARACTÉRISTIQUES VOCALES
Abstract
(EN) In an example implementation according to aspects of the present disclosure, a method may include identifying, via a first microphone of a device, when a user registered to use the device is speaking, and comparing a voice characteristic of the user, as detected by the first microphone, against a threshold value. If the voice characteristic exceeds the threshold value, the method may include unmuting a second microphone of the device for the user to participate in a teleconference.
(FR) Dans un exemple de mise en œuvre selon des aspects de la présente invention, un procédé peut comprendre l'identification, par l'intermédiaire d'un premier microphone d'un dispositif, du moment où un utilisateur enregistré pour utiliser le dispositif parle, et la comparaison d'une caractéristique vocale de l'utilisateur, telle que détectée par le premier microphone, à une valeur seuil. Si la caractéristique vocale dépasse la valeur seuil, le procédé peut consister à débloquer un second microphone du dispositif pour que l'utilisateur participe à une téléconférence.
