VOICE TO TELETYPE CODE CONVERTER RESEARCH PROGRAM. PART II. EXPERIMENTAL VERIFICATION OF A METHOD TO RECOGNIZE PHONETIC SOUNDS

Abstract

Speech-to-teletype code conversion oriented toward automatic recognition of phonetic units corresponding to phonemes is studied. Speech, analyzed by an 18-channel filter bank and converted to digital form for analysis with an RCA 501 Data Processing System, was studied to derive consonant recognition criteria. Moderate success was achieved in the recognition of 10 consonants and grouping of 8 additional consonants into classes. The consonant recognition program provided completely automatic location and recognition of the initial consonants with a mean accuracy of 60% for ten male talkers speaking isolated CVC words made up of all combinations of these initial consonants, ten vowels, and the final consonant d. A preliminary design of a speech recognizer based upon these studies is included. (Author)
