Vehicle communication systems and methods of operating vehicle communication systems

Abstract

Communication systems in a vehicle and methods of operating the same. The vehicle has a safety belt securable around a vehicle occupant. The system includes processor executable instructions for detecting, at a microphone, a first acoustic input and, in response, determining that the first acoustic input corresponds to audible speech at a speech time. The system detects vibration associated with a speaking vehicle occupant at a vibration time using a vibration sensor associated with the safety belt. The system determines whether the vibration time substantially corresponds to the speech time to identify whether the audible speech originates from the vehicle occupant on which the first safety belt is secured about. In response to identifying that the audible speech originates from the vehicle occupant associated with safety belt, the system adjusts loudspeaker output of at least one loudspeaker.
