A new fundamental frequency modification algorithm with transformation of spectrum envelope according to F0

Abstract

This paper proposes a new speech modification algorithm which makes it possible to change the fundamental frequency (Fo) while preserving high quality. One novel point of the algorithm is that the spectrum envelope is transformed according to amount of FO modification. Based on a codebook mapping formulation, transformation rules are generated using speech… (More)
