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 …

Accurate determination of glottal instants and electroglottographic (EGG) parameters is most
important in voice pathology analysis including multiple voice disorders: neurological …

Abstract 1 Time-scale representation of voiced speech is applied to voice quality analysis,
by introducing the Line of Maximum Amplitude (LoMA) method. This representation takes …

The objective of the proposed work is to accurately estimate the glottal closure instants
(GCIs) and glottal opening instant (GOIs) from electroglottographic (EGG) signals. This work …

This paper presents an approach to determine the open phase region of a glottal cycle
based on changes in the characteristics of the vocal tract system. The glottal closing phase …

This paper proposes an approach using spectral flatness measure to detect the glottal
closure instant (GCI) and the glottal open region (GOR) within each glottal cycle in voiced …

In voice analysis, the electroglottographic (EGG) signal has long been recognized as a
useful complement to the acoustic signal, but only when the vocal folds are actually …

The objective of this work is to develop an automatic method for estimating glottal opening
instants (GOIs) using Hilbert envelope (HE). The GOIs are secondary major excitations after …

In order to objectively assess the laryngeal vibratory behavior, endoscopic high-speed
cameras capture several thousand frames per second of the vocal folds during phonation …

The objective of this thesis is to analyze expressive voices to determine the features needed
for representing, describing and discriminating different types of expressions. Here …
