Impact Of Computerized “Sounding Out” On Spelling Performance Of A Child Who Uses Aac: A Preliminary Report, Jillian H Mccarthy, David R. Beukelman, Tiffany Hogan Dec 2011

Impact Of Computerized “Sounding Out” On Spelling Performance Of A Child Who Uses Aac: A Preliminary Report, Jillian H Mccarthy, David R. Beukelman, Tiffany Hogan

Spelling is a vital skill for people who rely on augmentative and alternative communication (AAC). The ability to spell words provides an opportunity to create novel and spontaneous communication and increases educational, social, and employment opportunities for children and adults. However, many children and youth who rely on AAC struggle to gain functional spelling skills and written language. The purpose of this preliminary investigation was to develop a strategy to provide auditory letter-sounds using commercially available computer equipment and to evaluate how such a computerized “sounding out” strategy influences spelling accuracy for one child who required AAC support. The spelling ...


Quantifying Articulatory Distinctiveness Of Vowels, Jun Wang, Jordan R. Green, Ashok Samal, David B. Marx Aug 2011

Quantifying Articulatory Distinctiveness Of Vowels, Jun Wang, Jordan R. Green, Ashok Samal, David B. Marx

Special Education and Communication Disorders Faculty Publications

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 ...

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 ...


Communication Support For People With Als, David R. Beukelman, Susan Fager, Amy Nordness Jan 2011

Communication Support For People With Als, David R. Beukelman, Susan Fager, Amy Nordness

Special Education and Communication Disorders Faculty Publications

Almost all people with amyotrophic lateral sclerosis (ALS) experience a motor speech disorder, such as dysarthria, as the disease progresses. At some point, 80 to 95% of people with ALS are unable tomeet their daily communication needs using natural speech. Unfortunately, once intelligibility begins to decrease, speech performance often deteriorates so rapidly that there is little time to implement an appropriate augmentative and alternative communication (AAC) intervention; therefore, appropriate timing of referral for AAC assessment and intervention continues to be a most important clinical decision-making issue. AAC acceptance and use have increased considerably during the past decade. Many people use ...


The Influence Of Neighborhood Density And Word Frequency On Phoneme Awareness In 2nd And 4th Grades, Tiffany Hogan, Ryan P. Bowles, Hugh W. Catts, Holly L. Storkel Jan 2011

The Influence Of Neighborhood Density And Word Frequency On Phoneme Awareness In 2nd And 4th Grades, Tiffany Hogan, Ryan P. Bowles, Hugh W. Catts, Holly L. Storkel

Special Education and Communication Disorders Faculty Publications

The purpose of this study was to test the hypothesis that two lexical characteristics – neighborhood density and word frequency – interact to influence performance on phoneme awareness tasks. Phoneme awareness was examined in a large, longitudinal dataset of 2nd and 4th grade children. Using linear logistic test model, the relation between words’ neighborhood density, word frequency, and phoneme awareness performance was examined across grades while co-varying type and place of deletion. A predicted interaction was revealed: words from dense neighborhoods or those with high frequency were more likely to yield correct phoneme awareness responses across grades. Findings support an expansion of ...


The Co-Emergence Of Cognition, Language, And Speech Motor Control In Early Development: A Longitudinal Correlation Study, Ignatius S. B. Nip, Jordan R. Green, David Marx Jan 2011

Although the development of spoken language is dependent on the emergence of cognitive, language, and speech motor skills, knowledge about how these domains interact during the early stages of communication development is currently limited. This exploratory investigation examines the strength of associations between longitudinal changes in articulatory kinematics and development of skills in multiple domains thought to support early communication development. Twenty-four children were investigated every 3 months between the ages of 9 and 21 months. Movements of the upper lip, lower lip, and jaw were transduced using a three-dimensional motion capture system to obtain age-related changes in movement speed ...


Subthalamic Nucleus Deep Brain Stimulation Changes Velopharyngeal Control In Parkinson’S Disease, Michael J. Hammer, Steven M. Barlow, Kelly E. Lyons, Rajesh Pahwa Jan 2011

Subthalamic Nucleus Deep Brain Stimulation Changes Velopharyngeal Control In Parkinson’S Disease, Michael J. Hammer, Steven M. Barlow, Kelly E. Lyons, Rajesh Pahwa

Special Education and Communication Disorders Faculty Publications

Purpose—Adequate velopharyngeal control is essential for speech, but may be impaired in Parkinson’s disease (PD). Bilateral subthalamic nucleus deep brain stimulation (STN DBS) improves limb function in PD, but the effects on velopharyngeal control remain unknown. We tested whether STN DBS would change aerodynamic measures of velopharyngeal control, and whether these changes were correlated with limb function and stimulation settings.

Methods—Seventeen PD participants with bilateral STN DBS were tested within a morning session after a minimum of 12 h since their most recent dose of anti-PD medication. Testing occurred when STN DBS was on, and again 1 ...


Current And Future Aac Research Considerations For Adults With Acquired Cognitive And Communication Impairments, Melanie Fried-Oken, David R. Beukelman, Karen Hux Jan 2011

Current And Future Aac Research Considerations For Adults With Acquired Cognitive And Communication Impairments, Melanie Fried-Oken, David R. Beukelman, Karen Hux

Adults with acquired language impairments secondary to stroke, traumatic brain injury, and neurodegenerative diseases are candidates for communication supports outside of the traditional restoration-based approaches to intervention. Recent research proves repeatedly that augmentative and alternative communication (AAC) provides a means for participation, engagement, conversation, and message transfer when individuals can no longer expect full return of premorbid communication skills and that inclusion of communication supports should begin early. We discuss current research and future directions for integrated systems of technical supports that include low-technology, high tech, and partner-dependent strategies for adults with severe and chronic aphasia, cognitive-communication problems resulting from ...
