Zero-Crossing and Noise Suppression in Auditory Wavelet Transformations
(1992)
A common sequence of operations in the early stages of most biological sensory systems is a wavelet transform followed by a compressive nonlinearity. In this paper, we explore the contribution of these operations to the ...
Neural Networks That Recognize Phonemes by Their Acoustic Features
(1991)
The ability of the ear model and lateral inhibitory networks (LIN) to preserve and enhance acoustic features of speech signal is examined by training neural networks to recognize phonemes by their LIN outputs. Using the ...
