Shift and Transformation in Salento: Investigating Change in the Polyphonic Structure and Performance Practice of Canti Polivocali in Southern Puglia
Musicologist (2018) Vol. 2, No. 1, pp. 96-114

This paper will focus on documenting change and transformation of polyphonic singing in the Salento region of lower Puglia (southern Italy), based on a comparative analysis of early field recordings and recently collected materials. Cantipolivocali (“multi-voiced songs”), the repertoire of ...

Quantitative Analysis of the Visor-Like Vertical Motion of the Cricoarytenoid Joint in the Living Subject
Journal of Voice (2016) Vol. 30, No. 3, pp. 354-364

The cricoarytenoid joint has a loose capsule and large cavity and may allow the arytenoid distanced from the cricoid cartilage. The objective was to quantify vertical motion of the arytenoid cartilage in the living subject. Axial computed tomography images from ...

The Effect of Moving Window on Acoustic Analysis
Journal of Voice (2016) Vol. 30, No. 1, pp. 5-10

Objective: To investigate the effects of the moving window method on acoustic measures and discrimination ability between normal and disordered voices. Fifty-three normal voices and 50 disordered voices were recruited. Three selection methods, the moving window method, the mid-vowel method, ...

Voice Tremor in Patients With Essential Tremor: Effects of Deep Brain Stimulation of Caudal Zona Incerta
Journal of Voice (2016) Vol. 30, No. 2, pp. 228-233

The present study aimed at evaluating the effect of deep brain stimulation (DBS) of the caudal zona incerta (cZi) on voice tremor in patients with essential tremor (ET). Twenty-six patients operated with cZi DBS were evaluated under two conditions: without ...

Aerodynamic Outcomes of Four Common Voice Disorders: Moving Toward Disorder-Specific Assessment
Journal of Voice (2016) Vol. 30, No. 3, pp. 301-307

The two goals of the present study were to (1) determine the ability of commonly used aerodynamic voice measures to capture change as a function of known interventions and (2) determine if certain aerodynamic measures demonstrate better responsiveness to change ...

A Comparison of Persian Vowel Production in Hearing-Impaired Children Using a Cochlear Implant and Normal-Hearing Children
Journal of Voice (2016) Vol. 30, No. 3, pp. 340-344

Normal-hearing (NH) acuity and auditory feedback control are crucial for human voice production and articulation. The lack of auditory feedback in individuals with profound hearing impairment changes their vowel production. The purpose of this study was to compare Persian vowel ...

Formant Frequencies and Bandwidths in Relation to Clinical Variables in an Obstructive Sleep Apnea Population
Journal of Voice (2016) Vol. 30, No. 1, pp. 21-29

We investigated whether differences in formants and their bandwidths, previously reported comparing small sample population of healthy individuals and patients with obstructive sleep apnea (OSA), are detected on a larger population representative of a clinical practice scenario. We examine possible ...

Effect of Voice Onset Type on Vocal Attack Time
Journal of Voice (2016) Vol. 30, No. 1, pp. 11-14

Vocal attack time (VAT) is the time lag between the growth of sound pressure (SP) and electroglottographic (EGG) signals at vocal initiation. The characteristics of voice initiation are associated with issues of vocal hygiene, efficiency, and quality. Vocal onsets have ...

Flow Glottogram Characteristics and Perceived Degree of Phonatory Pressedness
Journal of Voice (2016) Vol. 30, No. 3, pp. 287-292

Phonatory pressedness is a clinically relevant aspect of voice, which generally is analyzed by auditory perception. The present investigation aimed at identifying voice source and formant characteristics related to experts' ratings of phonatory pressedness. Study Design: Experimental study of the ...

The Effectiveness of the Comprehensive Voice Rehabilitation Program Compared With the Vocal Function Exercises Method in Behavioral Dysphonia: A Randomized Clinical Trial
Journal of Voice (2016) Vol. 30, No. 3, pp. 377.e11-377.e19

Objective: To evaluate the effectiveness of the Comprehensive Voice Rehabilitation Program (CVRP) compared with Vocal Function Exercises (VFEs) to treat functional dysphonia. Eighty voice professionals presented with voice complaints for more than 6 months with a functional dysphonia diagnosis. Subjects ...
