Abstract

A neural network that employs unsupervised learning was used on the output of a neurophysiologically based model of the auditory periphery [K. L. Payton, J. Acoust. Soc. Am. 83, 145–162 (1988)] to perform phoneme recognition. The auditory model incorporates steps describing the conversion from the acoustic pressure‐wave signal at the eardrum to the time course activity in auditory neurons. The model can process arbitrary time domain waveforms and yields the predicated neural firing rate. Continuous speech from ten speakers (three female and seven male) taken from the TIMIT database [W. Fisher et al., J. Acoust. Soc. Am. Suppl. 1 81, S92 (1987)] was processed through the auditory model for this experiment. The average firing rate of 20 channels from the auditory model was used to train a Kohonen self‐organizing feature map. The resulting context‐independent phoneme recognition performance (30% correct) was comparable to that of the SPHINX System [K. F. Lee and H. W. Hon, IEEE Trans. Acoust. Speech Signal P...
