A method is provided in one embodiment and includes establishing a communication session involving a first endpoint and a second endpoint that are associated with a video conference in a network environment. The first endpoint is associated with a first identifier and the second endpoint is associated with a second identifier. The method also includes evaluating first audio data for the first endpoint, and determining a vocative parameter associated with the first audio data, where image data can be rendered on a user interface at the first endpoint based on the detecting of the vocative parameter.
