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.
