Multimodal Dialogue System Grammars

We describe how multimodal grammars for dialogue systems can be written using the Grammatical Framework (GF) formalism. A proof-of-concept dialogue system constructed using these techniques is also presented. The software engineering problem of keeping grammars for different languages, modalities and systems (such as speech recognizers and parsers) in sync is reduced by the formal relationship between the abstract and concrete syntaxes, and by generating equivalent grammars from GF grammars.
