Evaluation of a Spoken Dialogue System for Virtual Reality Call for Fire Training

Abstract: : We present an evaluation of a spoken dialogue system that engages in dialogues with soldiers training in an immersive Call for Fire (CFF) simulation. We briefly describe aspects of the Joint Fires and Effects Trainer System, and the Radiobot-CFF dialogue system, which can engage in voice communications with a trainee in call for fire dialogues. An experiment is described to judge performance of the Radiobot CFF system compared with human radio operators. Results show that while the current version of the system is not quite at human-performance levels, it is already viable for training interaction and as an operator-controller aid.

Activity-Based Dialogue Analysis as Evaluation Method.

Abstract: This paper uses linguistic activity-based dialogue analysis in order to characterize, evaluate and compare activities. We find that human-human and human-machine interaction via radio are equally efficient but offer different styles of learning and instruction.
