7th International Conference on Spoken Language Processing
September 16-20, 2002
This paper describes the Speech Application Language Tags, or SALT, an emerging spoken language interface standard for multimodal or speech-only applications. A key premise in SALT design is speechenabled user interface shares a lot of the design principles and computational requirements with the graphical user interface (GUI). As a result, it is logical to introduce into speech the object-oriented, event-driven model that is known to be flexible and powerful enough in meeting the requirements for realizing sophisticated GUIs. It is hopeful that reusing this rich infrastructure can enable dialog designers to focus more on the core user interface design issues than on the computer and software engineering details. The paper centers the discussion on the Web-based distributed computing environment and elaborates how SALT can be used to implement multimodal dialog systems. How advanced dialog effects (e.g., cross-modality reference resolution, implicit confirmation, multimedia synchronization) can be realized in SALT is also discussed.
