Hearsay-II. Tutorial Introduction and Retrospective View

Abstract

The Hearsay-2 system, developed at CMU as part of the five-year ARPA speech-understanding project, was successfully demonstrated at the end of that project in September 1976. This report reprints two Hearsay II papers which describe and discuss that version of the system: The 'Hearsay-2 System: A Tutorial', and 'A Retrospective View of the Hearsay-2 Architecture'. The first paper presents a short introduction to the general Hearsay-2 structure and describes the September 1976 configuration of knowledge-sources; it includes a detailed description of an utterance being recognized. The second paper discusses the general Hearsay-2 architecture and some of the crucial problems encountered in applying that architecture to the problem of speech understanding.
