Abstract

A new pre-processing method for pitch smoothing is proposed. This methodology modifies the residual speech signal such that the pitch period evolves more smoothly without distorting perceptual speech quality. Thus, pitch can be effectively interpolated and transmitted only once per frame while presenting the long-term correlation of speech signal and maintaining the perceptual speech quality.
