Direct linkMcKenna, 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…

Pierce, Jenny L.; Tanner, Kristine; Merrill, Ray M.; Shnowske, Lauren; Roy, Nelson – Journal of Speech, Language, and Hearing Research, 2021
Purpose: The aims of this study were: (1) to quantify variability in voice production (as measured acoustically) within and across consecutive days in vocally healthy female speakers; (2) to identify which acoustic measures are sensitive to this variability; and (3) to identify participant characteristics related to such voice variability. Method:…

Patel, Rita R.; Ternström, Sten – Journal of Speech, Language, and Hearing Research, 2021
Purpose: The purpose of this study is to identify the extent to which various measurements of contacting parameters differ between children and adults during habitual range and overlap vocal frequency/intensity, using voice map-based assessment of noninvasive electroglottography (EGG). Method: EGG voice maps were analyzed from 26 adults (22-45…

Higgins, Ashley N.; Richardson, Kelly C. – Communication Disorders Quarterly, 2019
The purpose of this exploratory study was to examine speech characteristics in individuals with Parkinson's disease (PD) before and after participation in an 11-week choral singing intervention. Speech characteristics were analyzed using an acoustic measure of vowel space area (VSA) and a standardized speech intelligibility metric. Participants…

Watts, Christopher R.; Awan, Shaheen N. – Journal of Speech, Language, and Hearing Research, 2011
Purpose: In this study, the authors evaluated the diagnostic value of spectral/cepstral measures to differentiate dysphonic from nondysphonic voices using sustained vowels and continuous speech samples. Methodology: Thirty-two age- and gender-matched individuals (16 participants with dysphonia and 16 controls) were recorded reading a standard…

Lowell, Soren Y.; Barkmeier-Kraemer, Julie M.; Hoit, Jeannette D.; Story, Brad H. – Journal of Speech, Language, and Hearing Research, 2008
Purpose: To determine if respiratory and laryngeal function during spontaneous speaking were different for teachers with voice disorders compared with teachers without voice problems. Method: Eighteen teachers, 9 with and 9 without voice disorders, were included in this study. Respiratory function was measured with magnetometry, and laryngeal…
