An auditory model incorporating critical band filtering, short time adaptation, and temporal analysis of the auditory nerve responses is presented. Unlike previously proposed synchrony models, this model emphasizes the instantaneous amplitude (i.e. the envelope) of the neural responses rather than the instantaneous frequency as the carrier of perceptually relevant information. It is demonstrated how the auditory speech representation can be used for voiced/unvoiced classification, pitch extraction, phonetic segmentation, and classification of continuous speech. > |
