Inter- And Intra-Subject Variability: A Palatometric Study, Marybeth Corey Sanders Oct 2007

Inter- And Intra-Subject Variability: A Palatometric Study, Marybeth Corey Sanders

Theses and Dissertations

Electropalatometry (EPM) has proven to be a useful clinical and research tool for measuring tongue-to-palate contact. The goal of this study was to determine whether the development of a database of standardized palatometric articulation files is feasible by examining the variability which exists within and between speakers. Twenty standard American English dialect speakers were fitted with palatometer pseudopalates. Test stimuli were VCV nonsense words using a schwa in the initial position, the 15 palatal consonants, and three corner vowels, /a/, /i/, /u/. From these palatometric recordings a variability index was created to examine intra- and interspeaker variability. Different aspects of …


Patterns Of Anticipatory Coarticulation In Adults And Typically Developing Children, Kurtt R. Boucher Jun 2007

Patterns Of Anticipatory Coarticulation In Adults And Typically Developing Children, Kurtt R. Boucher

Theses and Dissertations

Coarticulation is the kinematic and spectral overlap between adjacent sounds during speech production. Coarticulation patterns in typical adults have been well established; however, the manner in which coarticulation is developed in children is still unclear. Research has provided conflicting views, showing that children exhibit more, less, or an equal degree of coarticulation when compared to adult speakers. Considering the divergent findings present in the literature regarding coarticulation in children, the purpose of the present study is to further investigate anticipatory coarticulation in typically developing young children between the ages of three and six years. This study focuses on the acoustic …
