Rong, Panying; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), have a devastating effect on speech muscle function that often results in severe communication deficits. Over the course of bulbar disease, tongue and jaw movements are modified, but their impact on speech is poorly understood. The aim of this study was to determine the…

Kuruvilla, Mili S.; Green, Jordan R.; Yunusova, Yana; Hanford, Kathy – Journal of Speech, Language, and Hearing Research, 2012
Purpose: The primary aim of the investigation was to identify deficits in spatiotemporal coupling between tongue regions in amyotrophic lateral sclerosis (ALS). The relations between disease-related changes in tongue movement patterns and speech intelligibility were also determined. Methods: The authors recorded word productions from 11…

Tasko, Stephen M.; Greilick, Kristin – Journal of Speech, Language, and Hearing Research, 2010
Purpose: The purpose of this study was to evaluate how speaking clearly influences selected acoustic and orofacial kinematic measures associated with diphthong production. Method: Forty-nine speakers, drawn from the University of Wisconsin X-Ray Microbeam Speech Production Database (J. R. Westbury, 1994), served as participants. Samples of clear…

Yunusova, Yana; Weismer, Gary G.; Lindstrom, Mary J. – Journal of Speech, Language, and Hearing Research, 2011
Purpose: In this study, the authors classified vocalic segments produced by control speakers (C) and speakers with dysarthria due to amyotrophic lateral sclerosis (ALS) or Parkinson's disease (PD); classification was based on movement measures. The researchers asked the following questions: (a) Can vowels be classified on the basis of selected…

Weismer, Gary; Yunusova, Yana; Westbury, John R. – Journal of Speech, Language, and Hearing Research, 2003
Articulatory discoordination is often said to be an important feature of the speech production disorder in dysarthria, but little experimental work has been done to identify and specify the coordination difficulties. The present study evaluated the coordination of labial and lingual gestures for /u/ production in persons with Parkinson's disease…

Yunusova, Yana; Weismer, Gary; Westbury, John R.; Lindstrom, Mary J. – Journal of Speech, Language, and Hearing Research, 2008
Purpose: This study compared movement characteristics of markers attached to the jaw, lower lip, tongue blade, and dorsum during production of selected English vowels by normal speakers and speakers with dysarthria due to amyotrophic lateral sclerosis (ALS) or Parkinson disease (PD). The study asked the following questions: (a) Are movement…

Steele, Catriona M.; Van Lieshout, Pascal H.H.M. – Journal of Speech, Language, and Hearing Research, 2004
The tongue functions as the primary articulator during the oropharyngeal stages of swallowing. However, detailed descriptions of the kinematics and spatiotemporal variability of tongue behaviors during swallowing are limited to a handful of analyses of data from the X-ray microbeam database. In this article, a new technique, electromagnetic…
