In this way, the dialogue performance can not be obtained before the system is on line, and the dialogue corpus should be recollected if the system is modified. Also, the effect of different factors, including system dialogue strategy, recognition and understanding accuracy or user response pattern, etc., on the dialogue performance can not be quantitatively identified because they can not be precisely controlled in different corpora. In this paper, a fundamental performance analysis scheme for dialogue systems based on a quantitative simulation approach is proposed. With this scheme the fundamental performance of a dialogue system can be predicted and analyzed efficiently without having any real spoken dialogue system implemented or having any dialogue corpus actually collected. How the dialogue performance varies with respect to each factor, from recognition accuracy to dialogue strategy, can be individually identified, because all such factors can be precisely controlled in the simulation. The quality of service for the spoken dialogue system can also be flexibly defined and the design parameters easily determined. This approach is therefore very useful for the design, development and improvement of spoken dialogue although the on-line system and real corpus will eventually be needed in the final evaluation and analysis of the system performance in any case. © 2000 IEEE. |
