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)
The German joint research project Verb mobil VM aims at the development of a speech to speech translation system This paper reports on research done in our group which belongs to Verbmobil s subproject on system architectures TP Our spe ci c research areas are the construction of parsers for spontaneous speech investiga tions in the parallelization of(More)
This paper discusses to which extent the concept of "anytime algorithms" can be applied to parsing algorithms with feature unification. We first try to give a more precise definition of what an anytinm algorithm is. We arque that parsing algorithms have to be classified as contract algorithms as opposed to (truly) it> terruptible algorithms. With the(More)
Verbmobil is a large German joint research project in the area spontaneous speech-to-speech translation sytems which is sponsored by the German Federal Ministery for Research and Education. In its first phase (1992–1996) ca. 30 research groups in universities, research institutes and industry were involved, and it entered its second phase in January 1997.(More)

In this paper we describe the linguistic processor of a spoken dialogue system. The parser receives a word graph from the recognition module as its input. Its task is to find the best path through the graph. If no complete solution can be found, a robust mechanism for selecting multiple partial results is applied. We show how the information content rate of(More)
Speech repairs occur often in spontaneous spoken dialogues. The ability to detect and correct those repairs is necessary for any spoken language system. We present a framework to detect and correct speech repairs where all televant levels of information, i.e., acoustics, lexis, syntax and semantics can be integrated. The basic idea is to reduce the search(More)
