Increasing the communication efficiency and accuracy associated with Command and Control (C2) operations is crucial in many aerospace applications. This communication intensive environment imposes a high workload on Air Traffic Controllers and other C2 personnel who rely heavily on a variety of communication tools to efficiently plan, direct, coordinate, and control assets during missions. The C2 task is further complicated by the suboptimal integration of the various communication media utilized in the operational environment. The fielded communication tool suites have serious limitations and are not poised to meet the needs of advancing technology. A multidisciplinary research team in the Battlespace Acoustics Branch of the Air Force Research Laboratory has developed the Multi-Modal Communications (MMC) tool suite which is specifically designed to increase communication effectiveness, provide efficient voice communication retrieval, navigation of saved data as well as reducing the perceived mental workload of the operators.
