In this paper, we integrate a simple non-parallel voice conversion (VC) system with a
WaveNet (WN) vocoder and a proposed collapsed speech suppression technique. The …

The increasing usage of speech in digital technology raises a privacy issue because speech
contains biometric information. Several methods of dealing with this issue have been …

Generally, those patients with dysarthria utter a distorted sound and the restrained
intelligibility of a speech for both human and machine. To enhance the intelligibility of …

This habilitation presents the last ten years of my research on the structured modelling of
speech signals. Speech, as an oral language, constitutes the most elaborate communication …

The research of singing voice conversion (SVC) has attracted more and more attention in
the field of artificial intelligence. This paper proposes a WD-GAN algorithm for singing voice …

The goal of foreign accent conversion (FAC) is to create a new voice with the voice identity
of a given second-language (L2) speaker but with a native (L1) accent. The main motivation …

Voice Conversion (VC) requires an alignment of the spectral features before learning the
mapping function, due to the speaking rate variations across the source and target speakers …

Singing voice conversion methods encounter challenges in achieving a delicate balance
between synthesis quality and singer similarity. Traditional voice conversion techniques …

In this research, singing/humming to instrument conversion techniques are proposed. In
humming to instrument, two models based on cycle-consistent adversarial networks …

We present a method to transform artificial notification sounds into various musical timbres.
To tackle the issues of ambiguous timbre definition, the lack of paired notification-music …
