Response Patterns of 'Primary-Like' Cochlear Nucleus Neurons to Excerpts from Sustained Vowels.
Abstract
This report compares the neural response patterns of eighth nerve and 'primary-like' cochlear nucleus neurons to excerpts from sustained vowels. The dominant intervals defined by neural firings within each pitch period of the response to the vowels were found to be the same in eighth nerve and 'primary-like' CN units. These intervals were found to be related to the pitch rate and first formant values of the vowels employed as stimuli. This finding provides support for the contention that the auditory system performs a temporal analysis rather than a frequency analysis of signals. The data gathered in these neurophysiological experiments are employed in developing design criteria for speech recognition systems based on the performance characteristics of the auditory nervous system.
