A Phone-oriented Segment Model of the Human Cortex - a Hypothesis

Authors: Harald Höge

Abstract:

This paper brings together perceptive knowledge of phone classification, biological knowledge of the auditory system (cochlea nuclei, inferior colliculus, primary and secondary auditory cortex), and statistic knowledge of acoustic models. Due to the finding we postulate: for perception the auditory system generates features extracted from critical bands. These features are statistic independent for adjacent phones the perception of phones occurs in the secondary cortex based on a segment model, where all statistic dependencies of the features are modeled correctly for whole utterances
