In this work, we present an experimental analysis of a Dialogue System for the automatization of simple telephone services. Starting from the evaluation of a preliminar version of the system we 1 conclude the necessity to desing a robust and flexible system suitable to have to have different dialogue control strategies depending on the characteristics of the user and the performance of the speech recognition module. Experimental results following the PARADISE framework show an important improvement both in terms of task success and dialogue cost for the proposed system. . | Proceedings of EACL 99 Robust and Flexible Mixed-Initiative Dialogue for Telephone Services Relaiio Gil José t and Tapias Daniel and Gancedo Maria c.

Experimental results following the PARADISE framework show an important improvement both in terms of task success and dialogue cost for the proposed system. 1 INTRODUCTION In this contribution we present some improvements on the design of a Dialogue Management System for the automatization of simple telephone tasks in a PABX environment automatic name dialing voice messaging . . From the point of view of its functionality our system is a very simple one because there is no need of advanced Plan Recognition strategies or General Problem Solving methods. However we think that even for these kind of dialogue sytems there is still a long way to demonstrate their usability in real situations by the general public . In our work we will concentrate on systems designed for the telephone line and for a wide range of potential users. Therefore our evaluations will be done taking into account different levels of speech recognition performance and user behaviours. In particular we will propose and evaluate strategies directed to increase the robustness against recognition errors and flexibility to deal with a wide range of users. We will use the PARADISE evaluation framework Walker et al. 1998
