The current study examines (near-)minimal pairs of breathy and modal phonation produced by ten native speakers of Gujarati in connected speech, across different vowel qualities and separated by nine equal timepoints of vowel duration. The results identify five spectral measures (i.e. H1–H2, H2–H4, H1–A1, H1–A2, H1–A3), four noise measures (i.e. cepstral peak prominence and three measures of har...

Previous studies show that phonation onset occurs as two eigenmodes of the vocal folds are synchronized by the interaction between the vocal folds and the glottal flow. This study examines the influence of the geometrical and biomechanical properties of the vocal folds on this eigenmode-synchronization process, with a focus on phonation threshold pressure and frequency. The analysis showed that...

OBJECTIVES/HYPOTHESIS Laryngeal adductor muscle dysfunction is a common cause of voice disorders. Reconstitution of adductor muscle function is often the target of therapy, but the effects of these muscles on voice production remain to be fully understood. This study investigated the differential roles of thyroarytenoid (TA) and lateral cricoarytenoid (LCA) muscles on voice production. STUDY ...

This paper presents a new reference dataset of sustained, sung vowels with attached labels indicating the phonation mode. The dataset is intended for training computational models for automated phonation mode detection. Four phonation modes are distinguished by Johan Sundberg [15]: breathy, neutral, flow (or resonant) and pressed. The presented dataset consists of ca. 700 recordings of nine vow...

The voice is apparently used in quite different manners in different styles of singing. Some of these differences concern the voice source, which varies considerably with loudness, pitch, and mode of phonation. We attempt to describe voice source differences between Classical, Pop, Jazz and Blues styles of singing as produced in a triad melody pattern by a professional female singer in soft, mi...

Voice training exploits semiocclusives, which increase vocal tract interaction with the source. Modeling results suggest that vocal economy (maximum flow declination rate divided by maximum area declination rate, MADR) is improved by matching the glottal and vocal tract impedances. Changes in MADR may be correlated with thyroarytenoid (TA) muscle activity. Here the effects of impedance matching...

UNLABELLED Objective. To determine best sedation protocol for videolaryngostroboscopy in children unable to tolerate non-sedated evaluation. Materials and Methods. Consecutive case series of 10 children with voice disturbances, unable to tolerate nonsedated videolaryngostroboscopy at an academic tertiary care children's hospital. Flexible fiberoptic videolaryngostroboscopy was performed and int...

The disorders of voice and speech in Parkinson’s disease (PD) result from involvements in several subsystems including respiration, phonation, articulation, and prosody. We investigated the feasibility of acoustic measures for the identification of voice and speech disorders in PD, using a quick vocal test consisting of sustained phonation, diadochokinetic task, and running speech. Various trad...

Lack of proper auditory feedback in hearing-impaired subjects results in functional voice disorder. It is directly related to discoordination of intrinsic and extrinsic laryngeal muscles and disturbed contraction and relaxation of antagonistic muscles. A total of twenty children in the age range of 5-10 years were considered for the study. They were divided into two groups: normal hearing child...

The effects of velopharyngeal insufficiency (VFI) or clefting on acoustic frequency–modal characteristics of human supraglottal spaces are investigated. Finite element (FE) modelling is supported by experimental investigation using a physical model of the vocal and nasal tract fabricated by the rapid prototyping technique from the FE model. The FE model was developed from magnetic resonance ima...
