This paper focuses on the strategies adopted to tackle problematic input and ease communication between modules in a Spanish railway information dialogue system for spontaneous speech. The paper describes the design and tuning considerations followed by the understanding module, both from a language processing and semantic information extraction point of view. Such strategies aim to handle the problematic input received from the speech recogniser, which is due to spontaneous speech as well as recognition errors.
