Voice Onset Time in Individuals with Hyperfunctional Voice Disorders: Evidence for Disordered Vocal Motor Control
Peer reviewed Peer reviewed
Direct linkDirect link
McKenna, Victoria S.; Hylkema, Jennifer A.; Tardif, Monique C.; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: This study examined vocal hyperfunction (VH) using voice onset time (VOT). We hypothesized that speakers with VH would produce shorter VOTs, indicating increased laryngeal tension, and more variable VOTs, indicating disordered vocal motor control. Method: We enrolled 32 adult women with VH (aged 20-74 years) and 32 age- and sex-matched…

Hurtado-Ruzza, Rafael; Iglesias, Óscar Álvarez-Calderón; Becerro-de-Bengoa-Vallejo, Ricardo; Calvo-Lobo, César; San-Antolín, Marta; Losa-Iglesias, Marta Elena; Romero-Morales, Carlos; López-López, Daniel – Journal of Speech, Language, and Hearing Research, 2021
Purpose: The association between voice alterations, health-related quality of life (HRQL), and chronic respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), has previously been reported. The aim of this study was to test the hypothesis that HRQL and dysphonia-associated handicap of patients diagnosed with asthma or…

Relative Fundamental Frequency in Children with and without Vocal Fold Nodules
Peer reviewed Peer reviewed
Direct linkDirect link
Murray, Elizabeth S. Heller; Segina, Roxanne K.; Woodnorth, Geralyn Harvey; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Relative fundamental frequency (RFF) is an acoustic measure that is sensitive to functional voice differences in adults. The aim of the current study was to evaluate RFF in children, as there are known structural and functional differences between the pediatric and adult vocal mechanisms. Method: RFF was analyzed in 28 children with vocal…

Relative Fundamental Frequency Distinguishes between Phonotraumatic and Non-Phonotraumatic Vocal Hyperfunction
Peer reviewed Peer reviewed

Murray, Elizabeth S. Heller; Lien, Yu-An S.; Van Stan, Jarrad H.; Mehta, Daryush D.; Hillman, Robert E.; Noordzij, J. Pieter; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2017
Purpose: The purpose of this article is to examine the ability of an acoustic measure, relative fundamental frequency (RFF), to distinguish between two subtypes of vocal hyperfunction (VH): phonotraumatic (PVH) and non-phonotraumatic (NPVH). Method: RFF values were compared among control individuals with typical voices (N = 49), individuals with…

Auditory-Perceptual Speech Features in Children with Down Syndrome
Peer reviewed Peer reviewed
Direct linkDirect link
Jones, Harrison N.; Crisp, Kelly D.; Kuchibhatla, Maragatha; Mahler, Leslie; Risoli, Thomas, Jr.; Jones, Carlee W.; Kishnani, Priya – American Journal on Intellectual and Developmental Disabilities, 2019
Speech disorders occur commonly in individuals with Down syndrome (DS), although data regarding the auditory-perceptual speech features are limited. This descriptive study assessed 47 perceptual speech features during connected speech samples in 26 children with DS. The most severely affected speech features were: naturalness, imprecise…

Short-Term Effect of Two Semi-Occluded Vocal Tract Training Programs on the Vocal Quality of Future Occupational Voice Users: "Resonant Voice Training Using Nasal Consonants" versus "Straw Phonation"
Peer reviewed Peer reviewed

Meerschman, Iris; Van Lierde, Kristiane; Peeters, Karen; Meersman, Eline; Claeys, Sofie; D'haeseleer, Evelien – Journal of Speech, Language, and Hearing Research, 2017
Purpose: The purpose of this study was to determine the short-term effect of 2 semi-occluded vocal tract training programs, "resonant voice training using nasal consonants" versus "straw phonation," on the vocal quality of vocally healthy future occupational voice users. Method: A multigroup pretest--posttest randomized control…

Kreisler, Alexandre; Vepraet, Anne Caroline; Veit, Solène; Pennel-Ployart, Odile; Béhal, Hélène; Duhamel, Alain; Destée, Alain – Journal of Speech, Language, and Hearing Research, 2016
Purpose: To better define the clinical characteristics of idiopathic oromandibular dystonia, we studied voice, speech, and swallowing disorders and their impact on activities of daily living. Method: Fourteen consecutive patients with idiopathic oromandibular dystonia and 14 matched, healthy control subjects were included in the study. Results:…
