Example : Multimodal interfaces require effective  parsing  and understanding of  utterances  whose content is distributed across multiple input modes. NAME_1 1998 presents an approach in which strategies for  multimodal integration  are stated declaratively using a  unification-based grammar  that is used by a  multidimensional chart parser  to compose inputs. This approach is highly expressive and supports a broad class of  interfaces , but offers only limited potential for mutual compensation among the input modes, is subject to significant concerns in terms of computational complexity, and complicates selection among alternative multimodal interpretations of the input. In this paper, we present an alternative approach in which  multimodal parsing and understanding  are achieved using a  weighted finite-state device  which takes  speech and gesture streams  as inputs and outputs their joint interpretation. This approach is significantly more efficient, enables tight-coupling of multimodal understanding with  speech recognition , and provides a general probabilistic framework for  multimodal ambiguity resolution .
