In this paper we describe an approach to automatic evaluation of both the speech recognition and understanding capabilities of a spoken dialogue system for train time table information. We use word accuracy for recognition and concept accuracy for understanding performance judgement. Both measures are calculated by comparing these modules' output with a(More)

In our paper we describe experiences in the eld of linguistic processing for spoken dialogue systems we made during the project Syslid 1. Within Syslid a linguistic component for three diierent domains was developed. We present a development strategy for the creation of linguistic knowledge bases for diierent domains as well as preliminary results achieved(More)
This paper reports the experiences we had in evaluating the ACCeSS system using the EAGLES evaluation metrics both at the input/output (black box evaluation) and component levels (glass box evaluation). We deliver an example of a complete evaluation of a continuous speech/mixed initiative system using these standards. Furthermore, we discuss some useful(More)
