SMALTO: advising interface designers on the use of speech in multimodal systems

Describes a tool which provides system designers with advice on the use of speech input and/or output modalities in combination with other modalities in the design of multimodal systems. The tool, which we call SMALTO (Speech Modality AuxiLiary TOol), implements a theory of speech functionality and incorporates structured data extracted from a large corpus of claims about speech functionality from the recent literature on speech and multimodality. We envisage that SMALTO can be used both as a stand-alone hypertext system and as part of a complete design environment
