Vocoders received renewed attention recently as basic components in speech synthesis
applications such as voice transformation, voice conversion and statistical parametric …

The modeling of speech production often relies on a source-filter approach. Although
methods parameterizing the filter have nowadays reached a certain maturity, there is still a …

Speech generated by parametric synthesizers generally suffers from a typical buzziness,
similar to what was encountered in old LPC-like vocoders. In order to alleviate this problem …

In this paper, we present an extension of a novel continuous residual-based vocoder for
statistical parametric speech synthesis. Previous work has shown the advantages of adding …

This thesis aimed at conducting research on the synthesis and expressive transformations of
the singing voice, towards the development of a high-quality synthesizer that can generate a …

In this paper, we present an extension of a novel continuous residual-based vocoder for
statistical parametric speech synthesis by addressing two objectives. First, because the …

A large part of the research carried out at the Phonetics and Speech Laboratory is
concerned with the role of the voice source in the prosody of spoken language, including its …

In this paper we present a flexible deterministic plus stochastic model (DSM) approach for
parametric speech analysis and synthesis with high quality. The novelty of the proposed …

Hypo and hyperarticulation refer to the production of speech with respectively a reduction
and an increase of the articulatory efforts compared to the neutral style. Produced …

HMM-based speech synthesis generally suffers from typical buzzi-ness due to over-
simplified excitation modeling of voiced speech. In order to alleviate this effect, several …
