This paper focuses on the increasing need for a more natural and sophisticated human-machine interaction (HMI). The research here presented shows work on the development of a restricted-domain spontaneous speech dialogue system in Spanish. This human-machine interface is oriented towards a semantically restricted domain: Spanish railway information. The paper focuses on the description of the understanding module, which performs the language processing once the dialogue moves have been recognised and transcribed into text. Following the morphological, syntactic and semantic analysis, the module generates a structured representation with the content of the user's intervention. This representation is passed on to the dialogue manager, which generates the system's answer. The dialogue manager keeps the dialogue history and decides what the reaction of the system should be, expressed by a new structured representation. This is sent to the natural language generator, which then builds the sentence to be synthesised.
