11. The speech recognition system of claim 7 wherein the quantizer is a fuzzy matrix quantizer further for generating respective fuzzy distance measures between the respective speech input signal and reference speech signal P line spectral pair frequencies using the corresponding generated distance measures; and wherein the second speech classifier is a neural network and the output data is a fuzzy distance measure proportional to a combination of the generated fuzzy distance measures.
12. The speech recognition system of claim 11 wherein the quantizer is a fuzzy matrix quantizer further for generating an observation sequence of indices indicating the relative closeness between the respective speech input signal and reference speech signal P line spectral pair frequencies; and wherein the second speech classifier includes u hidden Markov models and a fuzzy Viterbi algorithm module for determining a respective probability for each of the u hidden Markov models that the respective hidden Markov model produced the observation sequence.
