A Self-Adaptive Fuzzy Recognition System for Speech Sounds

The paper presents a part of the investigations being carried out by the authors on methods and applications of pattern recognition and image analysis. A class of problems on automatic computer recognition of speech sounds using fuzzy logic is being dealt with. The input patterns are usually given as deterministic data although they may contain some fuzziness, and the output decision is also deterministic but the process of classification is fuzzy in nature.

The results of a computer simulation of the recognition model using Telugu (an important Indian Language) vowel sounds uttered by a number of speakers in CNC context is presented. The first three vowel formant frequencies were considered to be the recognition features. The algorithm with selected representative points with a number of guard zones which are ellipsoidal in the three dimensional feature space around the representative vectors of the classes is taken as a supervisor.
