Correlation of Multiple Measures of Voice Evaluation Among Individuals with Muscle Tension Dysphonia: An Exploratory Study.

Primary Muscle Tension Dysphonia (MTD) occurs in the absence of structural or neurologic etiologies. Patients with MTD are frequently encountered in clinics and are evaluated using multiple measures of voice evaluation. Studies reporting on the correlation of multiple measures of voice evaluation among individuals with MTD are minimal, which led to this study.

Thermal, Acoustic, and Self-Perceptual Measures of Pre-Post Vocal Change After Surface Hydration in Speech-Language Pathologists.

Purpose: Numerous clinical findings support the idea that increased surface laryngeal hydration prevents and manages voice problems in professional voice users. However, empirical evidence for surface laryngeal hydration (nebulized saline solution) through multidimensional voice measures is lacking, especially in speech-language pathologists (SLPs). Hence, the present study investigated the effect of surface hydration using nebulized saline solution on voice quality using thermal, acoustic, and self-perceptual measures in SLPs.

A Multiparametric Acoustic and Self-Perceptual Measure of Laryngeal Hydrations in Speech-Language Pathologists: A Preliminary Longitudinal Investigation.

Purpose: Speech-language pathologists (SLPs) work with individuals with communication disorders. Their work can strain their voice, resulting in dysphonia, adversely affecting their career and quality of life. Laryngeal hydration can prevent vocal damage and improve vocal performance in SLPs.

Implementation of Eclectic Voice Therapy Program via Telepractice in Hyperfunctional Voice Disorders: A Preliminary Efficacy Study.

Purpose: Hyperfunctional voice disorder (HFVD) has a multifaceted origin. Individuals with HFVD work in professions that demand high vocal usage and are bound to work for longer hours with very inflexible work schedules. In consequence, it can be speculated that an eclectic voice therapy program that uses combinatory approaches delivered via telepractice could bring about better efficiency of voice in these individuals.

Comparison of Two Multiparameter Acoustic Voice Outcome Indices in the Treatment of Hyperfunctional Voice Disorders: Dysphonia Severity Index and Acoustic Voice Quality Index.

Introduction: The Dysphonia Severity Index (DSI) and Acoustic Voice Quality Index (AVQI) are the two widely used multiparameter acoustic instrumented indices that estimate dysphonia severity and track treatment outcomes. This study compared the performance of these two indices in identifying voice quality changes with eclectic voice therapy in individuals with hyperfunctional voice disorders (HFVD).

Method: Twenty individuals with HFVD including eight males and 13 females in the age range of 20-55 years received an eclectic voice therapy program named the Comprehensive Voice Habilitation Program.

Nasalance, Nasal Airflow and Perceived Nasality in Carnatic Singers and Non-singers.

This study aims to compare the nasalance and nasal airflow between professional singers trained in Carnatic classical singing and non-singers. We also aimed to correlate perceived nasality with objective measurements of nasalance and nasal airflow. A total of 40 female participants (20 to 50 years) were involved in this study.

Effect of Anchor Voices and Listener Expertise on Auditory-Perceptual Judgments of Voice Quality Using the GRBAS Scale.

Objectives: This study aimed to determine the effect of anchor voices and listener expertise on auditory-perceptual judgment of voice quality using the GRBAS scale.

Methods: This study utilized a modified crossover design with counterbalancing. Anchor voices for each parameter of the GRBAS scale were chosen based on expert consensus.

Psychometric Properties of the Voice Handicap Index-10 in Kannada.

Objectives: This study aimed to derive the 10-item voice handicap index in the Kannada language (VHI-K10) from the existing VHI-30 in Kannada (VHI-K30). We also aimed to examine several psychometric properties of the newly derived VHI-K10, such as internal consistency, reliability, concurrent validity, discriminant validity, and diagnostic accuracy.

Methods: Initially, VHI-K10 was derived from the existing VHI-K30 through item reduction, consistent with the recommendations for item reduction of the voice handicap index.

Analysis of Gene in Individuals with Non Syndromic Hearing Impairment in Relation with Associated Mutations.

Background: Hearing Loss (HL) is the most common sensory disorder. HL commonly ranges from mild to severe. Persons with HL face difficulty in hearing conversations or sounds through one ear or both ears, which impacts one's ability to interact with others.

Prevalence of Voice Problems and Associated Risk Factors Among Tamil-Speaking Imams.

Purpose: Voice of Professional Voice Users (PVUs) are of particular interest to practicing Speech-Language Pathologists. There is a dearth of studies concerning the prevalence of voice disorders and the associated risk factors among Tamil-speaking Imams. We address this research gap using non-experimental survey research.

Effect of Voice Projection Training on Acoustic and Auditory-Perceptual Characteristics of Voice in Tamil-Speaking Imams.

Background: Imams are professional voice users at risk of developing voice problems. Speech-Language Pathologists need to provide intervention programs to target risk factors associated with voice disorders and improve the voice quality of Imams. However, studies examining the effect of vocal training for Imams are limited in the literature.

A Preliminary Study on the Effect of Bhramari Pranayama on Voice of Prospective Singers.

Introduction: Bhramari Pranayama (BP) is a yogic breathing technique that involves producing a vibrating constant pitch sound emulating the buzzing of bumblebee. Since BP deals with breathing and humming in the sustained pitch, it is hypothesized that it can have implications for improving voice quality in individuals. However, there is a dearth of research available to support this assumption.

Acoustic Voice Quality Index (AVQI) in the Measurement of Voice Quality: A Systematic Review and Meta-Analysis.

Introduction: Acoustic Voice Quality Index (AVQI) is a multiparametric construct of voice quality recognized for its clinical and research applications around the globe. This study aimed to review the validity and diagnostic accuracy of AVQI (v02&03) and determine the effects of age and gender.

Methods: This is a systematic review and meta-analysis registered with the PROSPERO registry.
