Speech production can be regarded as a process where a time-varying vocal tract system
(filter) is excited by a time-varying excitation. In addition to its linguistic message, the speech …

Automatic detection of voice pathology enables objective assessment and earlier
intervention for the diagnosis. This study provides a systematic analysis of glottal source …

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 …

Precise specification of the voice source would facilitate better modelling of expressive
nuances in human spoken interaction. This paper focuses on the transformed version of the …

Human voice has been a great source of fascination and an object of research for over 100
years. During that time numerous technologies have sprouted around the voice, such as the …

This paper summarizes the results of our investigations into estimating the shape of the
glottal excitation source from speech signals. We employ the Liljencrants–Fant (LF) model …

The representation of the glottal source is of paramount importance for describing para-
linguistic information carried through the voice quality (eg, emotions, mood, attitude) …

This thesis documents a range of research carried out on the topic of glottal source and
voice quality analysis. Initially, a review is given of the physiological and acoustic correlates …

Within this thesis an imitative sound synthesis system will be introduced that is applicable to
most quasi-harmonic instruments. The system bases upon single-note recordings that …

This article investigates into recently emerging approaches that use deep neural networks
for the estimation of glottal closure instants (GCI). We build upon our previous approach that …
