This paper describes a fully operational system for analyzing all aspects of continuous speech from word recognition up to linguistic representation. Many systems rely on fully grammatical speech input, others use only shallow analysis without using declarative linguistic knowledge. We propose a flexible processing, where the depth of the analysis varies according to internal (quality of the speech input) and/or external (limitations, e.g. of processing time) criteria. In architecture and system design, special effort was made to cover effects of spontaneous speech (e.g. unknown words, pauses, or sentence breaks). The described system is part of a speech dialog system not discussed in this paper.
