A Locally Organized Parser for Spoken Input

Abstract

A locally organized parsing system (LPARS) has been developed for use in a continuous speech recognizer, accepting as its input a string of phonemes which contains ambiguity and error. The system is locally organized in the sense that it can construct local parse structures from word candidates recognized fairly reliably in all parts of an input utterance. These local structures are used as “islands of reliability” and serve as context to guide the search for more highly garbled words which might complete the utterance.
