Cognitive Headset Awareness with External Voice Interruption Detection

An approach is provided in which an information handling system invokes a conferencing session over a computer network between a first user utilizing a headset and one or more second users. The information handling system detects an audible interruption from a third user proximate to the first user, while the headset inhibits the first user from detecting the audible interruption. Next, the information handling system sends an interruption notification to the first user in response to determining that the audible interruption matches at least one of a set of notification triggers corresponding to the first user. In turn, the information handling system captures a dialog between the one or more second users in the conferencing session in response to the first user accepting the interruption notification.
