There is increasing emphasis on use of connected speech for acoustic analysis of voice disorder, but the differential impact of disorder on initiation, maintenance and termination of phonation has received little attention. This study introduces a new measure of dynamic changes at onset of phonation during connected speech, phonation stabilisation time (PST), and compares this measure with conv...

The automatic detection of vocal cord/vocal tract diseases from the medically disordered speech is a challenging task in the medical field. An automatic diagnostic system for the medically disordered voice is proposed in this paper. The developed system takes speech recorded by a patient having a disorder in his/her voice, as an input. The system gives the type of voice disorder as an output. T...

BACKGROUND Speech production and speech phonetic features gradually improve in children by obtaining audio feedback after cochlear implantation or using hearing aids. The aim of this study was to develop and evaluate automated classification of voice disorder in children with cochlear implantation and hearing aids. METHODS We considered 4 disorder categories in children's voice using the foll...

The aim of this study was to compare the self-assessed vocal handicap of laryngectomees treated with three different communication methods: tracheoesophageal speech, esophageal speech and electrolarynx. Forty-eight patients, 40 males and 8 females, who had undergone total laryngectomy for laryngeal carcinoma were enrolled in the study. Depending on the voice restoration method, all patients wer...

    Background: Parkinson’s disease (PD) is a progressive neurological disorder and many PD patients experience some type of voice and speech disorders during the course of illness. In this study, the aim was to investigate the effect of Lee Silverman voice treatment (LSVT) on improving voice difficulties in patients with mild PD using voice handicap index (VHI).    Methods: This interventiona...

The occurrence of voice disorder and of non-modal phonation were measured in the speech of 53 children. Thirty seven monolingual English speaking children with developmental speech disorder and compared with that in 16 age-matched children with normal speech development. The children’s ages ranged from 4 to 6 years. The speech disordered children were further assigned to 3 subgroups according t...

OBJECTIVE/HYPOTHESIS The purpose of this paper is to introduce the rate of divergence as an objective measure to differentiate between the four voice types based on the amount of disorder present in a signal. We hypothesized that rate of divergence would provide an objective measure that can quantify all four voice types. STUDY DESIGN A total of 150 acoustic voice recordings were randomly sel...
