A simple new method for estimating temporally stable power spectra is introduced to provide
a unified basis for computing an interference-free spectrum, the fundamental frequency (F0) …

This article presents comprehensive technical information about STRAIGHT and TANDEM-
STRAIGHT, a widely used speech modification tool and its successor. They share the same …

This article introduces a new set of tools based on TANDEM-STRAIGHT, a fundamental
reformulation of STRAIGHT, a speech analysis, modification and resynthesis system …

Voice morphing is a powerful tool for exploratory research and various applications. A
temporally variable multi-aspect morphing is extended to enable morphing of arbitrarily …

An interference-free representation of the instantaneous frequency of constituent harmonic
components of periodic signals is introduced. The power weighted average instantaneous …

A systematic framework for non-periodic excitation source representation is proposed for
high-quality speech manipulation systems such as TANDEM-STRAIGHT, which is basically …

Another simple and high-speed F0 extractor with high temporal resolution based on our
previous proposal has been developed by adding a higher-order symmetry measure. This …
