Abstract

The paper describes a system, in JAVA for written and visual scenario generation used to collect speech corpora in the framework of a tourism information system. Experimental evidence shows that the corpus generated with visual scenarios has a higher perplexity and a richer vocabulary than the corpus generated using the same conceptual derivations to produce textual scenarios. Furthermore, there is evidence that textual scenarios influence speakers in the choice of the lexicon used to express the concepts more than visual scenarios
