Approximate reasoning approach to pattern recognition consists of ling
uistic rules tied together by means of two concepts: fuzzy implication
s and a compositional rule of inference. In this paper, first we study
the applicability of different interpretations of fuzzy implication t
o pattern recognition problem and subsequently compare their performan
ces over a set of synthetic data. Finally, we use the most applicable
(according to our study) interpretations of implication for vowel reco
gnition of three different Indian languages and we obtain very promisi
ng results.
