Modeling of spoken dialogue control for improvement of dialogue efficiency

In this research, we aim at the establishment of a method of controlling dialogues in accordance with the changes of performance in computation. So that the system takes the most suitable dialogue strategy according to performance in computation, it needs to calculate evaluation functions modeled with performance in computation in the inside all time. In this paper, we model dialogue control centered on `system transparency' with computation time and accuracy of system's processes. Then, we simulate this model by controlling dialogue strategies. We also confirm effectiveness of the model by preliminary experiment using the prototype of spoken dialogue system.
