This paper presents a new method for understanding utterances in spoken dialogue. The method is characterized by an understanding rule that accepts an utterance sequence in which each utterance has its own speaker identifier. This new idea enables the speech understanding system to understand a dialogue composed of sequences of short phrases each possibly uttered by different speakers. The method is also applied to a spoken dialogue system by regarding the dialogue system itself as one of the speakers. We give a formal description of the new dialogue understanding method. Sample behavior of a spoken dialogue system with our new method is also presentend followed by an evaluation in terms of the amount of dialogue description. The evaluation shows our method reduces the amount of understanding state description.
