ASL: Architectures for Speech and Language Processing

Further advances in speech recognition heavily depend on the design of architectures which are ex-ible enough to accomodate very diierent requirements for the ow of data and hypotheses. These requirements result from the peculiarities of the speech understanding process, which is a complex decision procedure covering a number of diierent levels of language description. The paper identiies some reasons for assuming additional communicative needs within the recognition system and points out two areas of ongoing research: the design of prototype speech processing modules, which basically rely on inter-module interaction and the development of software-tools for the creation and modiication of diierent architectural layouts.
