Block diagram of a spoken dialogue system. At turn t, the user utters U, which is recognized by ASR to be W. ν is a semantic representation of user's intended dialogue act. q is the dialogue state, where A u is the hypothesized user's dialogue act. g is user's goal, and H is dialogue history. b is a distribution over dialogue states. A s is the system's action. The function π is called policy and it encodes the strategy of the dialogue manager.
