A Feature Geometry Based Lexicon Model For Speech Applications

This paper proposes a generic feature geometry based lexical representation of phonological description using inheritance networks which has applications in various areas of speech technology. The feature geometry based lexicon model provides the linguistic knowledge for a generic lexicon tool which allows application-specific lexica to be generated. The relevance of this approach to interactive dialogue in multi-modal systems lies in the representation of parallel information which is structured with respect to temporal relations. This paper first presents the formal modelling of the feature geometry based lexical representation and then provides examples of specific output formats discussing in particular the temporal coordination of multilinear representations for speech technology applications.
