Digital simulation of vowel processing in the peripheral auditory system
Steven Greenberg · The Journal of the Acoustical Society of America · 1978
The response of the peripheral auditory system to digitally generated and human-articulated vowels was modelled at the level of the cochlea and auditory nerve. The simulation operates upon the spectral density function to derive an estimate of the excitation pattern of the VIIIth nerve and thereby serves to illustrate the manner in which certain acoustic attributes of the vocalic signal such as fundamental frequency, formant pattern, formant bandwidth, and glottal pulse shape affect the simulated discharge pattern of the auditory nerve.
