Abstract :
We propose a new approach to the modeling of speech based on cues from the peripheral auditory system. Our approach attempts to incorporate the dynamic adaptation of biological auditory systems to varying sound by simplistically formulating a dual-processing strategy that treats unvoiced and voiced speech as deserving of different processing. Preliminary studies show that this approach possesses significant noise robustness
