The German prototype (SUn Germ) of the European project SUndial 1 aims at a telephone based real time system for oral dialogues to inquire a database on intercity train schedules. To enhance system Performance one of our goals is to improve the recognition accuracy by minimizing the perplexity. We will show that our bigram language model component which can be dynamically changed according to the context of the dialogue, can further reduce this perplexity. This paper describes the integration of linguistic knowledge into the continuous speech recognizer2. Especially our experiments in the interaction of the language model component and the dialogue manager are presented. In our evaluation part we compare our approaches with and without dynamically varied language models by an overview of results of the Performance measurement.

Im SPICOS II-Projekt (Siemens-Philips-IPO-Continuous Speech Understanding and Dialogue) wird ein Dialogsystem implementiert, das es erlaubt, Datenbankinhalte in fliesend gesprochener Sprache im Dialog zu erschliesen. Das System befindet sich im Aufbau und wird Anfang 1990 prototypisch fertiggestellt. Es verarbeitet einen Wortschatz von ca. 1000 Wortern mit Anfragen zu Dokumenten im Burobereich und zu Personen im Projekt. Das System ist sprecheradaptiv.(Bild 1 zeigt einen Uberblick uber den Gesamtaufbau des Systems.)
