In this paper, we propose the perceptual speech processing and the phonetic feature mapping, which are inspired by human auditory perceptual characteristics. The proposed perceptual speech processing is based on three perceptual characteristics and consists of three independent processing steps: masking effect, minimum audible field renormalization, and mel-scale resampling. They remove unperceptible spectral components, and adjust magnitude and frequency scales of speech spectra, respectively.doi:10.1109/89.824695 fatcat:po3lcn7knrd7plxqgudtcsnhha
