The purpose of this literature review is to describe and discuss instrumental assessment
techniques of the velopharyngeal function in order to diagnose velopharyngeal disorders …

Purpose: Hypernasality and atypical voice characteristics are common features of dysarthric
speech due to amyotrophic lateral sclerosis (ALS). Existing acoustic measures have been …

Objective: The voice low tone to high tone ratio (VLHR) is defined as the power ratio of low
frequency to high frequency energy obtained by dividing the voice spectrum with a specific …

Hypernasality is associated with various diseases and interferes with speech intelligibility. A
recently developed quantitative index called voice low tone to high tone ratio (VLHR) was …

Humans can recognize someone's identity through their voice and describe the timbral
phenomena of voices. Likewise, the singing voice also has timbral phenomena. In vocal …

Purpose This study aimed to compare 2 quantitative acoustic measures of nasality in
children with cleft lip and palate (CLP) and healthy controls using formalized perceptual …

Voice analysis is an emerging technology which has the potential to provide low-cost, at-
home monitoring of symptoms associated with a variety of health conditions. While voice has …

The nasal cavity and its related structures make significant contributions to human
phonation, especially the resonance of voice spectra. The voice spectra of the nasal …

Objective Due to the multidimensional nature of resonance disorders, multivariate diagnostic
assessment is advisable. The nasality severity index (NSI) is based on this point of view …

Abstract Purpose The Nasality Severity Index 2.0 (NSI 2.0) forms a new, multiparametric
approach in the identification of hypernasality. The present study aimed to investigate the …
