Glottal inverse filtering (GIF) refers to methods of estimating the source of voiced speech, the
glottal volume velocity waveform. GIF is based on the idea of inversion, in which the effects …

Electroglottography (EGG) is a low-cost, noninvasive technology for measuring changes of
relative vocal fold contact area during laryngeal voice production. EGG was introduced …

Now in its Third Edition, this book emphasizes the physiological perspective of voice
disorders—and the behavioral and emotional factors that can influence these changes …

Normalized amplitude quotient (NAQ) is presented as a method to parametrize the glottal
closing phase using two amplitude-domain measurements from waveforms estimated by …

This article presents the results of glottal open-quotient measurements in the case of singing
voice production. It explores the relationship between open quotient and laryngeal …

The purpose of this study was to document changes in aerodynamic and glottographic
aspects of vocal function in patients with Parkinson disease who received two forms of high …

The great majority of current voice technology applications rely on acoustic features, such as
the widely used MFCC or LP parameters, which characterize the vocal tract response …

The development of the speech production system was investigated using a crosssectional
design that included children aged 4–14 years and adults. Given that the size and internal …

Simultaneous procedures for making aerodynamic and kinematic observations of the
laryngeal and chest wall systems were used to investigate variations in vocal intensity in …

This study presents a new frequency domain parameter, Parabolic Spectral Parameter
(PSP), for the quantification of the glottal volume velocity waveform. PSP is based on fitting a …
