Vocational Experiences Of Survivors Of Severe Tbi With Diverse Employment Patterns: An Explanatory Mixed Method Design, Erin J. Bush
Vocational Experiences Of Survivors Of Severe Tbi With Diverse Employment Patterns: An Explanatory Mixed Method Design, Erin J. Bush
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Employment status is a salient outcome following traumatic brain injury (TBI). A return to productive activity relates in complex ways to quality of life, and loss of employment competence has potentially devastating effects on survivors. Currently, inadequate information exists about the distribution of occupations held by survivors, post-injury employment stability, and the frequency that survivors return to their pre-injury occupations. The research presented herein addressed these issues. This study consisted of two phases. Through Phase 1, the researcher gathered quantitative employment data regarding a pool of 283 survivors of severe TBI. She then conducted telephone interviews of family members of …
Quantifying Articulatory Distinctiveness Of Vowels, Jun Wang, Jordan R. Green, Ashok Samal, David B. Marx
Quantifying Articulatory Distinctiveness Of Vowels, Jun Wang, Jordan R. Green, Ashok Samal, David B. Marx

The articulatory distinctiveness among vowels has been frequently characterized descriptively based on tongue height and front-back position; however, very few empirical methods have been proposed to characterize vowels based on time-varying articulatory characteristics. Such information is not only needed to improve knowledge about the articulation of vowels but also to determine the contribution of articulatory imprecision to poor speech intelligibility. In this paper, a novel statistical shape analysis was used to derive a vowel space that depicted the quantified articulatory distinctiveness among vowels based on tongue and lip movements. The effectiveness of the approach was supported by vowel classification accuracy …
Perceptual And Acoustical Comparisons Of Motor Speech Practice Options For Children With Childhood Apraxia Of Speech, Amy Nordness
Perceptual And Acoustical Comparisons Of Motor Speech Practice Options For Children With Childhood Apraxia Of Speech, Amy Nordness
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Children with childhood apraxia of speech (CAS) need intensive and accurate practice to establish an accurate motor plan and improve their speech production. Computer-led practice led to a greater quantity of practice and was preferred over parent-led practice. Further knowledge regarding children’s accuracy of speech during independent practice is needed to determine if computer-led practice is a viable practice tool. Twelve children diagnosed with CAS, between 3-0 and 7-11 years of age, participated in speech practice during computer-led, parent-led, and clinician-led practice. Comparisons of perceptual accuracy of consonants and vowels, acoustical accuracy of stops, vowels, and fricatives, and variability of …
Audibility As A Predictor Of Speech Recognition And Listening Effort, Ryan W. Mccreery
Audibility As A Predictor Of Speech Recognition And Listening Effort, Ryan W. Mccreery
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Two studies were conducted to evaluate how audibility influences speech recognition and measures of working memory in children with normal hearing. Specifically, audibility limitations related to background noise and limited bandwidth were analyzed, as these factors are characteristic of the listening conditions encountered by children with hearing loss who wear hearing aids.
In the first study, speech recognition was measured for 117 children and 18 adults with normal hearing. Stimulus bandwidth and the level of background noise were varied systematically in order to evaluate predictions of audibility based on the Speech Intelligibility Index. Results suggested that children with normal hearing …

Purpose: The primary purpose was to demonstrate the feasibility of executing treatment tasks focused on increasing loudness in a group format for individuals with Parkinson’s disease (PD). A second purpose was to report preliminary pre-to-post treatment outcomes for individuals with PD immediately after they complete the group program. Methods: The group intervention is described. Fifteen adults with PD who participated in the group and three clinicians leading the group provided feedback about the execution of the intervention. The participants also provided voice samples and self-ratings of voice handicap once before completing the 8-week voice group and once immediately after completing …
