On short-time cepstra of voiced speech

A brief review of the basics of cepstral deconvolution is followed by a refined model for short-time cepstra of voiced speech. The model provides a better understanding of the nature of short-time cepstra and of the heuristics of deconvolution. It brings to light a number of properties which are important for the successful application of short-time cepstral deconvolution to voiced speech. It allows a set of rules to be derived which can be used for the optimization of cepstral deconvolution systems
