7. The speech recognition system of claim 1 further comprising: a quantizer having a codebook having C codewords for generating the distance measure between each of the P line spectral pair frequencies of the speech input signal and each of a plurality of reference speech signals; and a second speech classifier to receive the output data based on the distance measures and generate speech classification output data to classify the speech input signal as one of u vocabulary words.
