Speech Understanding Systems

Abstract

Work has shifted from research in the areas of phonetic recognition and linguistic processing to integration of an experimental speech understanding system. This mid-term system, scheduled for completion in April 1974, will be composed of phonetic recognition, linguistic processing, and functional response modules. The system task is the vocal command of a data retrieval, analysis, and display facility intended to support a researcher in studying the acoustic correlates of phonemic events. A first version of an acoustic phonetic 'front end' has been developed and tested with a corpus of 73 sentences. It has been operated in the system environemnt with two different linguistic processing modules, and encoraging results have been achieved in preliminary testing. The tests involved vocabularies of 200 to 500 words and context-free grammars of 111 to 300 production statements.
