Abstract
In this paper, we propose a cognitive process model of spoken dialogue. In order to make an interactive dialogue system, we need two management processes: one is an understanding process which manages the subprocess of utterance understanding through response generation; the other is a dialogue management process which aggregates the utterances to the discourse segment and manages focus and intentions of dialogue. Furthermore, in applying the model to spoken dialogue systems, we have to deal with misunderstandings caused by speech recognition errors. Our model specifies the cognitive process of whole dialogue understanding process and stipulates the interaction between understanding process and dialogue management process. We also specify the recovering method from communication errors into this cognitive process. Therefore, our model is suitable for implementing cooperative spoken dialogue systems.
