Abstract
A spoken dialogue system has a large number of complex problems to overcome. To simplify matters, two key assumptions are almost always taken. First, only dialogues with exactly two participants are considered and second, all interactions between the system and the user are in the form of turns

Notes
- 1.
The name belief state is traditionally reserved in the literature for systems that use a particular statistical assumption, called “partial observability” (Sect. 2.3.2). However, even when this model is not used, the system’s internal state will always be a representation of its beliefs about what has happened in the dialogue. It is therefore reasonable to use the term for all models.
