We present a neural fuzzy network architecture devoted to the recognition of specific segmental phonetic features.. A neural fuzzy network allows us to select the best acoustic parameters associated with eachfeature and to compute an phonetic segmental plausibility score. Segments result from the alignements provided by an allophone based Markov model. These segmental scores are then processed by a statistical post-processing system for reordering the N-best HMM hypotheses. This post-processing is based on the computation of segmental scores for each solution under the hypotheses of a correct solution and of an incorrect solution. Moreover, we present comparison results between these neural fuzzy network architecture and a classical one, on 3 speaker-independent telephone databases.
