Abstract:
Speech interfaces are becoming more and more popular as a means to interact with virtual environments but the development
and integration of these interfaces is usually still ad hoc, especially the speech grammar creation of the speech interface
is a process commonly performed by hand. In this paper, we introduce an approach to automatically generate a speech grammar
which is generated using semantic information. The semantic information is represented through ontologies and gathered from
the conceptual modelling phase of the virtual environment application. The utterances of the user will be resolved using queries
onto these ontologies such that the meaning of the utterance can be resolved. For validation purposes we augmented a city
park designer with our approach. Informal tests validate our approach, because they reveal that users mainly use words represented
in the semantic data, and therefore also words which are incorporated in the automatically generated speech grammar.
