Abstract
Alterations imposed to speech signal by the peripheral auditory system, have been studied by mean of the physical model described by J. M. Dolmazon and L. Bastet [J. Acoust. Soc. Am. 65, S14 (1979)]. This model can reproduce for any acoustical stimulus the mean discharge frequency of an auditory nerve fiber after a linear simulation of basilar membrane motion and a nonlinear simulation of mechanical to neural transduction for taking into account two‐tone suppression effects or combination tone generation. We present a comparison between features extracted, from the input speech signal, by the model and by conventional analysis techniques to estimate the influence of the well‐known nonlinear effects in speech perception. Special care has been taken for vowel analysis to clarify formant interaction.
