Advantages Of Percutaneous Endoscopic Gastrostomy Tube Placement In Patients With Head And Neck Cancer Who Receive Radiation As Part Of Their Treatment, Nevin Thul
Speech and Hearing Sciences ETDs
The use of percutaneous endoscopic gastrostomy tubes as an intervention strategy in head and neck cancer was investigated in this retrospective chart review. Twenty-five veterans met the inclusion criteria and were categorized into two groups – use of prophylactic percutaneous endoscopic gastrostomy and absence of percutaneous endoscopic gastrostomy tube placement. Medical charts were reviewed and data extracted included weight, swallow function, swallow exercise compliance, and physical and social quality of life for 2 years post-treatment. Month-to-month data were compared across the two groups with respect to weight, swallow function, swallow exercise compliance, and physical and social quality of life scores. …

The Effect Of Breathy And Strained Vocal Quality On Vowel Perception, Sarah Nieman
Speech and Hearing Sciences ETDs
INTRODUCTION: Research into speech intelligibility in dysarthria historically focuses on articulation deficits. However, voice quality deficits associated with motor speech disorders may also impact speech perception. This study investigates how breathy and strained vocal quality affects vowel identification and ratings of vowel goodness.
METHODS: A healthy speaker recorded vowels with normal, simulated breathy and simulated strained voice quality. Acoustic, physiologic, and perceptual measures confirmed the presence of the desired voice deficits. 16 volunteer listeners participated in three perceptual tasks: vowel identification, vowel goodness ratings, and voice quality ratings.
RESULTS: In the voice quality rating task, listeners detected voice quality deficits …
