Representation of Spectral Profiles in the Auditory System, II: Detection of Spectral Peak Shape Changes
Based on the ripple analysis model outlined in Part I of this paper, predictions are made for the detection of shape changes in spectral peak profiles. Peak shape is uniquely described in terms of two parameters: bandwidth ...
Representation of Spectral Profiles in the Auditory System, I: A Ripple Analysis Model
A model of profile analysis is proposed in which a spectral profile is assumed to be represented by a weighted sum of sinusoidally modulated spectra (ripples). The analysis is performed by a bank of bandpass filters, each ...
Speech Coding over Noisy Channels
This chapter contains a discussion of quantization over noisy channels. The effects of channel noise on the performance of vector quantizers are discussed and algorithms for the design of noisy-channel vector quantizers ...
