Abstract
This paper describes an utterance classification method for combining multiple dialog systems. For reducing effort of developing spoken dialog systems, several dialog systems have been proposed that do not require complicated dialog description. However, these systems are so simple that only very limited type of dialogs are accepted by these systems. We propose a spoken dialog development by combining these simple dialog systems for developing a dialog system that accepts more flexible dialogs. Combination of dialog systems is based on utterance classification. We conducted an utterance classification experiment, and 77.1% of the utterances including out-of-task utterances were correctly classified.
