Voice Onset Time As A Clinical Indicator Of Hypofunctional Voice Disorders., Amanda Arnold, Lisa Phillips, Lindsay Pickler, Whitney White, Amanda Mccamey, Christopher Mccrea

ETSU Faculty Works

The purpose of this study was to measure and compare the voice onset times (VOTs) of healthy individuals using a normal and breathy voice in an effort to determine if VOT can be used as a noninvasive clinical indicator of laryngeal function. Recordings were made of 20 adults between the ages of 20-48 with normal laryngeal function, each using a normal (Group 1) and breathy voice (Group 2). The participants’ productions were designed and collected in such a manner to control for speaking rate, vowel context, pitch, and loudness; all of which have been shown to influence VOT. A mixed …

Relative Timing Of Speech Motor Events At Utterance Invitation In Persons Who Do And Do Not Stutter, Bryan Thomas Brown

Masters Theses

Speech production is a highly complex speech motor activity that presumably requires a high degree of coordination between articulatory, respiratory and phonatory subsystems. Stuttering may be caused by breakdowns in speech motor coordination. The current study attempted to evaluate timing relationship between these systems at speech initiation in the perceptually fluent speech of people who do and do not stutter. To study this, tongue blade speed histories, respiratory transitions from inspiratory to expiratory gestures, and acoustic events at the initiation of perceptually fluent speech in persons who stutter and normally fluent speakers were analyzed in relative time. To identify the …

Promoting Speech And Vocabulary Development Through Specialized Storybooks In Children With And Without Cleft Palate., Joellyn Ruth Smith

Electronic Theses and Dissertations

This study investigated changes in vocabulary and speech production in response to storybooks embedded with specialized language prompts and speech recasts. Six children received intervention, 3 with cleft palate (CLP), displaying speech-language delays, and 3 with nonclefts, each 12-24 months of age. A multiple baseline design across behaviors was implemented by a clinician. Results indicated all children increased use of target vocabulary and production of stop consonants, while reducing compensatory articulation errors. Generalization of targets to a picture-naming task, a free-play task, and to the home was observed. Effect sizes were moderate-to-high. Children with CLP required more sessions to achieve …

The Challenges Of Bilingual Speech-Language Therapy: Perspectives From Speech-Language Pathologists, Dana Marie Roberts

Renée Crown University Honors Thesis Projects - All

In the United States, the increasing population of people who speak a language other than English, especially the Spanish-speaking population, has resulted in a greater number of linguistically diverse clients appearing on speech-language pathologists’ (SLPs’) caseloads and has also effectively increased the demand for bilingual SLPs. However, bilingual SLPs continually report a number of challenges in the field, which could explain why recruiting bilingual SLPs is difficult. This study highlighted the importance of assessing the challenges faced by bilingual SLPs through an analysis of the perspectives of four Spanish-English speaking bilingual clinicians in Central New York. The challenges the participants …

Pragmatic Assessment In Autism Spectrum Disorders: A Comparison Of A Standard Measure With Parent Report, Brian Reichow, Shawn Salamack, Rhea Paul, Fred Volkmar, Ami Klin

Communication Disorders Faculty Publications

The purpose of this study was to investigate the concurrent validity of subtests on the Comprehensive Assessment of Spoken Language (CASL) by comparing them with the assessment of communication and social skills on the Vineland Adaptive Behavior Scales (Vineland). The participants were 35 children and adolescents with higher functioning autism spectrum disorders (ASD) who had received both the CASL and the Vineland. Results of the study suggest that the Pragmatic Judgment and Inferences subtests of the CASL appeared to document the difficulties that individuals with ASD had in adaptive use of language for communication.

Nonlinear Source-Filter Coupling In Phonation: Vocal Exercises, Ingo Titze, Tobias Riede, Peter Popolo

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Nonlinear source-filter coupling has been demonstrated in computer simulations, in excised larynx experiments, and in physical models, but not in a consistent and unequivocal way in natural human phonations. Eighteen subjects (nine adult males and nine adult females) performed three vocal exercises that represented a combination of various fundamental frequency and formant glides. The goal of this study was to pinpoint the proportion of source instabilities that are due to nonlinear source-tract coupling. It was hypothesized that vocal fold vibration is maximally destabilized when F0 crosses F1, where the acoustic load changes dramatically. A companion paper provides the theoretical underpinnings. …

Effects Of Dichotic Auditory Training On Children With Central Auditory Processing Disorder, Kiley Edwards Stephenson

Doctoral Dissertations

(Central) auditory processing disorder (CAPD) is a condition in which individuals with normal hearing present with difficulties often associated with hearing loss. While there are currently many tests available for the CAPD assessment, there are very few therapies for the remediation of a CAPD. A new therapy program, called Dichotic Auditory Training (DAT), aimed at improving the performance of those individuals with CAPD, was the focus of this study. Eight children between the ages of seven and twelve went through the four week training. The Staggered Spondaic Word (SSW) test, the SCAN-C/A, and a test designed after the DAT …

Review Of Medical Imaging Devices For The Integration Of Medical Technology And Earmold Production And Grant Proposal Development, Michelle L. Saltarrelli

Doctoral Dissertations

The first purpose of this study was to assess the feasibility of a medical device to replace the current method of earmold production. The medical device would be used to scan the external ear (i.e., external auditory canal and pinna), scan the dimensions to an imaging software system, and finally send the three-dimensional image electronically to a milling machine for the production of earmolds and hearing aid shells. Currently, audiologists use an eight step process described by Dillon (2001) which due to the invasive nature of the procedure presents potential complications to both the clinician and client, The potential complications …

Efficacy Of Central Auditory Processing Case History Form Used At The Louisiana Tech University Speech And Hearing Center, Michelle L. Smith

Doctoral Dissertations

Central auditory processing disorder (CAPD) is a deficiency in processing of auditory information. Due to this deficiency, a variety of behaviors can be seen including listening difficulties in background noise, difficulties following oral instruction, and difficulties discriminating and identifying speech sounds. These behaviors result in inattention and academic difficulties. With these characteristics being present in other disorders such as attention deficit/hyperactivity disorder, language/learning deficits, and high functioning autism (i.e., Asperger's syndrome) diagnosis of CAPD becomes complicated.

The Louisiana Tech University Speech and Hearing Center uses a CAPD case history for a child that was adopted from Robert Keith in 2003. …

Repetition Priming And Anomia: An Investigation Of Stimulus Dosage, Catherine A. Off

Speech, Language, Hearing, and Occupational Sciences Faculty Publications

In a recent review of anomia management, Maher & Raymer reported that 30% of aphasia intervention research from 1946 to 2001 focused on naming; however, "despite this proliferation of case reports and small group studies, there is still no clear agreement on how best to manage these deficits" (Maher & Raymer, 2004, p. 13). The inconsistency of acquisition, maintenance, and generalization effects observed across participants and types of treatment protocols is likely to stem from an inadequate knowledge base about how subject and treatment variables influence learning.

One treatment variable that has received increasing attention over the past two or …

Production Of Syllable Stress In Speakers With Autism Spectrum Disorders, Rhea Paul, Nancy Bianchi, Amy Augustyn, Ami Klin, Fred Volkmar

Communication Disorders Faculty Publications

This paper reports a study of the ability to reproduce stress in a nonsense syllable imitation task by adolescent speakers with autism spectrum disorders (ASD), as compared to typically developing (TD) age-mates. Results are reported for both raters’ judgments of the subjects’ stress production, as well as acoustic measures of pitch range and duration during stressed and unstressed syllable production. Results reveal small but significant differences between speakers with ASD and typical speakers in both perceptual ratings of stress and instrumental measures of duration of syllables. The implications of these findings for understanding prosodic deficits in ASD are discussed.

Velo-Cardio-Facial Syndrome: 30 Years Of Study, Robert J. Shprintzen

Communication Disorders Faculty Publications

Velo-cardio-facial syndrome is one of the names that has been attached to one of the most common multiple anomaly syndromes in humans. The labels DiGeorge sequence, 22q11 deletion syndrome, conotruncal anomalies face syndrome, CATCH 22, and Sedlačková syndrome have all been attached to the same disorder. Velo-cardio-facial syndrome has an expansive phenotype with more than 180 clinical features described that involve essentially every organ and system. The syndrome has drawn considerable attention because a number of common psychiatric illnesses are phenotypic features including attention deficit disorder, schizophrenia, and bipolar disorder. The expression is highly variable with some individuals being essentially …

Comparison Of Two Treatment Conditions For Young Children With Speech Sound Disorders, Megan Overby, A. Lynn Williams, John Bernthal

ETSU Faculty Works

The purpose of this study was to compare treatment outcomes between stimulus presentation conditions to children with moderate to severe SSD: a traditional paper presentation versus a computer software generated presentation. The participants were four monolingual kindergarten children with moderate to severe SSD. A multiple baseline across behaviors single subject design was employed in the study. Two non-stimulable, non-cognate sounds from two different manner categories were selected as sound targets. One sound error was treated using paper stimuli presented in a traditional paper table-top presentation (TAB condition) while the other sound error was treated using stimuli presented on the computer …

Dysphagic Patient Compliance With Thickened Liquid Recommendations, Carrie Potts

Master's Theses and Doctoral Dissertations

In light of the growing prevalence of dysphagic patients on Speech-Language Pathologists’ caseloads and the frequent prescription of thickened liquids as a treatment strategy (Garcia, Chambers & Molander, 2005; Low, Wyles, Wilkinson & Sainsbury, 2001; Robbins, Nicosia, Hind, Gill, Blanco, & Logemann, 2002), our limited understanding of the factors that contribute to patient adherence presents a significant challenge to the management of dysphagia. The purpose of this qualitative study was to better understand the decisions patients make regarding dysphagia recommendations. Drawing upon adherence/compliance research from the field of behavioral medicine, the results of this study revealed a complex interplay of …
