Abstract

This paper presents a model for the unified semantic representation of shape conveyed by speech and coverbal 3-D gestures. The representation is tailored to capture the semantic contributions of both modalities during free descriptions of objects. It is shown how the semantic content of shape-related adjectives, nouns, and iconic gestures can be modeled and combined when they occur together in multimodal utterances like "a longish bar" + iconic gesture. The model has been applied for the development of a prototype system for gesture recognition and integration with speech.
