The Natural Language Generation and Dialogue Systems Group conducts research within the broad field of Conversational AI and spoken dialogue systems focussing on methods and technology to realise natural voice-first interaction between humans and machines. Employing machine learning methods, the group's research addresses the following questions: which properties and abilities must a system have to act in a natural manner, which factors make the behaviour of the system to be perceived as natural, and how to realise this natural interaction from a technical point of view. In other words, the goal is to understand all factors that constitute “natural system behaviour” in the context of spoken interaction.
