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.

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.

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.

Validation of Acoustic Breathiness Index (ABI) in the South Indian Population.

Background: Acoustic Breathiness Index (ABI) is an acoustic model which equates to the auditory-perceptual (A-P) measure of breathiness. Globally, ABI has been validated in multiple languages. To date, empirical studies validating ABI in the South Indian population have not been carried out.

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.

Comparison and Validation of Acoustic Voice Quality Index Version 2 and Version 3 among South Indian Population.

Background: Acoustic Voice Quality Index (AVQI) has emerged in the recent past as a robust multiparametric voice quality evaluation tool. Two versions of AVQI derived using the program PRAAT have found extensive clinical and research applications. These versions have been validated in several languages around the world.

Effect of Age and Gender on Acoustic Voice Quality Index Across Lifespan: A Cross-sectional Study in Indian Population.

Background: The human voice is dynamic and changes throughout the life span. The effects of age and gender on acoustical measures of voice quality have been well established. Assessment of voice quality using multiparametric measures has been recommended over singleton measures.
