SOME SIMPLE RULES FOR SELF-ADAPTIVE MECHANICAL RECOGNITION OF VOWELS.
HEMDAL, JOHN
THE VALUE OF THE ACOUSTIC PARAMETERS OF A PHONETIC EVENT VARY FROM SPEAKER TO SPEAKER AND, TO SOME EXTENT, FROM DAY TO DAY. THE ABSENCE OF STABLE INVARIANTS IN SPEECH PRODUCTION IMPLIES THAT A COMPUTER MUST BE SELF-ADAPTIVE IN ORDER TO RECOGNIZE THE PHONETIC EVENTS OF DIFFERENT SPEECH PRODUCTIONS. SELF-ADAPTATION, HOWEVER, REQUIRES THAT PHONEME SEPARATION AND CLASSIFICATION BE ACCOMPLISHED BY THE USE OF SIMPLE BOUNDARIES AND SIMPLE CHANGES IN THESE BOUNDARIES, WHILE MAINTAINING THE REQUISITE ACCURACY. THIS EXPERIMENT PRESENTS DATA THAT INDICATE THAT VOWELS MAY BE CLASSIFIED BY USING SIMPLE BOUNDARIES IN THE F1-F2 PLANE IF SUFFICIENT CONTROL OVER THE SPEECH PRODUCTION HAS BEEN EXERCISED. FORMANT LOCATIONS OF 176 PRODUCTIONS OF EIGHT VOWELS FOR NINE SPEAKERS ARE PRESENTED IN WHICH IT IS SHOWN THAT SUITABLE ACCURACY OF CLASSIFICATION IS OBTAINED BY A BOUNDARY OF CONSTANT F1 AND A BOUNDARY OF CONSTANT F2. THE SUGGESTION IS MADE THAT THESE BOUNDARIES, WHILE BASED ON VOWEL PRODUCTION, MAY BE OF SIGNIFICANCE IN VOWEL PERCEPTION.
