Automatic Speech Recognition (ASR) involves mainly
two steps; feature extraction and classification
(pattern recognition). Mel Frequency Cepstral Coeff
icient (MFCC) is used as one of the prominent featu
re
extraction techniques in ASR. Usually, the set of a
ll 12 MFCC coefficients is used as the feature vect
or in
the classification step. But the question is whethe
r the same or improved classification accuracy can
be
achieved by using a subset of 12 MFCC as feature ve
ctor. In this paper, Fisher’s ratio technique is us
ed for
selecting a subset of 12 MFCC coefficients that con
tribute more in discriminating a pattern. The selec
ted
coefficients are used in classification with Hidden
Markov Model (HMM) algorithm. The classification
accuracies that we get by using 12 coefficients and
by using the selected coefficients are compare
