Processing natural language dialogues obviously is much more than simply processing a sequence of more than one sentence. Similarly, processing spoken dialogues is much more than handling just another type of input.
Our working hypotheses (relying at least on minimal cognitive claims) are, that in-tegration of speech and language must be incremental, synchronous and more or less deterministic. In other words, processing must These principles first of all require a much more elaborated architecture for the inter-connection of all the modules on all levels and not only another (spoken language) lexicon and some more specific modules. A sequential architecture where modules follow each other in a fixed sequence (say in accordance to a phonetic/linguistic layer model) and work as filters on the set of hypotheses from the lower level, will not meet the principles explained above.
This paper describes the principles and decisions concerning the system architecture with-in the project ASL (Architectures for Integrative Speech and Language Processing). We do not report on all those activities in the project which contrast parallel and connectionist architectures to explicit software architectures. Two examples will sketch the requirements of such a speech/language system:
