Theses and Dissertations
The speech of individuals with Parkinson's disease (PD) is typically characterized as lacking in proper prosody because of its monopitch and monoloud quality, in addition to its reduced intensity. These qualities make it difficult for others to understand speakers with PD. The purpose of the current study was to identify what individuals with PD would do vocally, if anything at all, to improve speech production following a simulated misunderstanding of what they had just said. The study evaluated the performance of 5 individuals with PD and compared their performance to 5 age- and sex-matched controls. Specifically, measures of vocal intensity …

Exploration Of Lip Shape Measures And Their Association With Tongue Contact Patterns, Jessica Lynn Wagner
Theses and Dissertations
A variety of tools and techniques have been developed to measure the movements of the vocal tract, specifically of the tongue and lips. In recent years, computer technology has allowed for extensive exploration of these precise movements and for the development of speech recognition systems. However, there has been relatively little work on the combination of visible facial movements and internal articulatory activity. In this study, two different technologies were used to explore the internal and external movements of speech production in eight speakers: palatometry quantified tongue contact patterns and computerized video image analysis was used to derive lip shape …
