Changes in Phonation and Their Relations with Progress of Parkinson’s Disease
Applied Sciences, 2018 Hypokinetic dysarthria, which is associated with Parkinson’s disease (PD), affects several speech dimensions, including phonation. Although the scientific community has dealt with a quantitative analysis of phonation in PD patients, a complex ...

IEEE/ACM Transactions on Audio Speech and Language Processing, 2023 Speech from people with Parkinson's disease (PD) are likely to be degraded on phonation, articulation, and prosody. Motivated to describe articulation deficits comprehensively, we investigated 1) the universal phonological features that model ...

A cross-language acoustic space for vocalic phonation distinctions
Language, 2023 :Many languages use phonation types for phonemic or allophonic distinctions. This study examines the acoustic structure of the phonetic space for vowel phonations across languages. Our sample of eleven languages includes languages with contrastive modal,

The maximum phonation time as marker for voice treatment efficacy: A network meta‐analysis
Clinical Otolaryngology, 2022 There is a diversity in treatment approaches for voice therapy in which aerodynamic treatment effects between the approaches are lacking. The evidence of voice treatments on the maximum phonation time (MPT) was quantified using the statistical approach ...

On H1-H2 as an acoustic measure of linguistic phonation type.
Journal of the Acoustical Society of America, 2022 The measure H1-H2, the difference in amplitude between the first and second harmonics, is frequently used to distinguish phonation types and to characterize differences across voices and genders.

Hybrid aeroacoustic approach for the efficient numerical simulation of human phonation.
Journal of the Acoustical Society of America, 2020 A hybrid aeroacoustic approach was developed for the efficient numerical computation of human phonation. In the first step, an incompressible flow simulation on a three-dimensional (3 D) computational grid, which is capable of resolving all relevant ...

The role of F0 and phonation cues in Cantonese low tone perception.
Journal of the Acoustical Society of America, 2020 For languages that primarily exploit F0 to signal tonal contrast, the role of phonation cues in tonal perception remains controversial. This study revisits the use of F0 and phonation cues in Cantonese low tone perception (tone 4, 21/tone 6, 22) using ...

Phonation threshold flow measurements in normal and pathological phonation [PDF]
The Laryngoscope, 2009 AbstractObjectives/Hypothesis:Phonation threshold flow (PTF) may provide a tool to assess laryngeal function and could differentiate between normal and pathological voices. Both polyps and nodules contribute to an increased PTF by creating an incomplete glottal closure and increased vocal fold mass and thickness.Study Design:Prospective study.Methods ...

The voice of patients with laryngeal carcinoma after oncosurgery [PDF]
Archive of Oncology, 2005 The voice of patients indicated for surgical procedures in treating of dysphonia is already damaged before the operation. The problem, which exists at the level of glottis patients usually try to solve by compensative mechanisms.
