Voice transformation (VT) aims to change one or more aspects of a speech signal while
preserving linguistic information. A subset of VT, Voice conversion (VC) specifically aims to …

A vocoder-based speech synthesis system, named WORLD, was developed in an effort to
improve the sound quality of real-time applications using speech. Speech analysis …

An algorithm is proposed for estimating the band aperiodicity of speech signals, where
“aperiodicity” is defined as the power ratio between the speech signal and the aperiodic …

A fundamental frequency (F0) estimator named Harvest is described. The unique points of
Harvest are that it can obtain a reliable F0 contour and reduce the error that the voiced …

Speech data conveys sensitive speaker attributes like identity or accent. With a small
amount of found data, such attributes can be inferred and exploited for malicious purposes …

In this paper, we investigate the simultaneous modeling of multiple emotions in DNN-based
expressive speech synthesis, and how to represent the emotional labels, such as emotional …

More and more people turn to online voice communication with loudspeaker-equipped
devices due to its convenience. To prevent speech leakage, soundproof rooms are often …

Generating versatile and appropriate synthetic speech requires control over the output
expression separate from the spoken text. Important non-textual speech variation is seldom …

Voice-enabled interactions provide more human-like experiences in many popular IoT
systems. Cloud-based speech analysis services extract useful information from voice input …

As a fundamental problem in speech processing, pitch tracking has been studied for
decades. While strong performance has been achieved on clean speech, pitch tracking in …
