Perceptual And Physiologic Analysis Of Dystussia In Amyotrophic Lateral Sclerosis, Stephanie Anne Watts

USF Tampa Graduate Theses and Dissertations

Swallowing and cough are two vital functions that are reflexive in nature and are related to each other in terms of shared neural and anatomical space. When a disorder impacts normal and effective swallowing and/or cough, the consequences can be life-threatening. Evaluation and treatment of swallowing and cough disorders can fall under the scope of practice of the speech-language pathologist and speech-language pathologists often are leading professionals. Furthermore, much of the current research on swallowing and cough is spearheaded by speech-language pathologists often working with a multi-disciplinary team. The focus of this dissertation is on the clinical evaluation of cough …

Neural And Behavioral Mechanisms Of Clear Speech, Jenna Silver Luque

USF Tampa Graduate Theses and Dissertations

Clear speech is a speaking style that has been shown to improve intelligibility in adverse listening conditions, for various listener and talker populations. Clear-speech phonetic enhancements include a slowed speech rate, expanded vowel space, and expanded pitch range. Although clear-speech phonetic enhancements have been demonstrated across a variety of talkers, only a subset of these changes may be required for listeners to benefit perceptually from clear speech. Furthermore, while current literature has provided some understanding of the phonetic enhancements that are typical of clear speech and the improvements in intelligibility resulting from its use, less is understood regarding how listeners …

Discourse Changes Following Severe Traumatic Brain Injury: A Longitudinal Study, Elizabeth Young

Speech and Hearing Sciences ETDs

Purpose: There are few longitudinal data charting recovery of discourse skills following severe traumatic brain injury (TBI). Limited knowledge about the trajectory of discourse recovery and the best tools for assessing communication abilities in persons with TBI (PWTBIs) restricts detection of communication impairment and the ability to make informed prognostic judgments following TBI. This study sought to contribute longitudinal data to the research base, using clinically efficient measures that are sensitive to communication deficits associated with TBI and that use nuanced scoring systems to provide detailed characterization of discourse.

Methods: Twenty-three PWTBIs completed picture description tasks at 3 (or 6) …

Manipulation Of Auditory Feedback In Individuals With Normal Hearing And Hearing Loss, Le Truc Linh Vaccarello

Electronic Thesis and Dissertation Repository

Auditory feedback, the hearing of one’s own voice, plays an important role in the detection of speech errors and the regulation of speech production. The limited auditory cues available with a hearing loss can reduce the ability of individuals with hearing loss to use their auditory feedback. Hearing aids are a common assistive device that amplifies inaudible sounds. Hearing aids can also change auditory feedback through digital signal processing, such as frequency lowering. Frequency lowering moves high frequency information of an incoming auditory stimulus into a lower frequency region where audibility may be better. This can change how speech sounds …

A Comparison Of Pass Rates Across Three Language Screeners For Spanish-English Bilingual Children, Mariajose Bosanko

LSU Master's Theses

There is limited research regarding the efficacy of the language screening process, especially for bilingual populations. The purpose of this study was to examine the pass rates of three language screeners when administered to Spanish-English bilingual and ELL children. A total of ten Spanish-English bilingual children enrolled in either Pre-K, kindergarten, or first grade completed each screener. The screeners were: the Preschool Language Scales Spanish Screening Test-Fifth Edition (PLSSST-5; Zimmerman et al., 2012a), the Bilingual English Spanish Oral Screener (BESOS; currently in development; Lugo-Neris et al., n.d.), and the Diagnostic Evaluation of Language Variation-Screening Test (DELV-S; Seymour et al., 2003). …

Cognitive And Neurobiological Degeneration Of The Mental Lexicon In Primary Progressive Aphasia, Jet M. J. Vonk

Dissertations, Theses, and Capstone Projects

The ease with which we use the thousands of words in our vocabulary stands in stark contrast to our difficulty establishing how they are organized in our mind and brain. The breakdown of language due to cortical atrophy in primary progressive aphasia (PPA) creates conditions to study this organization at a cognitive and neurobiological level in that the three variants of this disease, namely non-fluent, logopenic, and semantic PPA, each bear their own signature of language-specific decline and cortical atrophy. As the impaired regions in each variant are linked to different lexical and semantic attributes of words, lexical decision performance …

Development And Validation For A Mobile Speech-In-Noise Audiometric Task, Tommy Peng

McKelvey School of Engineering Theses & Dissertations

Traditional speech-in-noise hearing tests are performed by clinicians with specialized equipment. Furthermore, these tasks often present contextually weak sentences in background babble, which are poor representations of real-world situations. This study proposes a mobile audiometric task, Semantic Auditory Search, which uses the Android platform to bypass the need for specialized equipment and presents multiple tasks of two competing real-world conversations to estimate the user’s speech-in-noise hearing ability. Through linear regression models built from data of seventy-nine subjects, three Semantic Auditory Search metrics have been shown to have statistically significant (p < 0.05) with medium effects sizes for predicting QuickSIN SNR50. The internal consistency of the task was also high, with a Cronbach’s alpha of 0.88 or more across multiple metrics. In conclusion, this preliminary study suggests that Semantic Auditory Search can accurately and reliably perform as an automated speech-in-noise hearing test. It also has tremendous potential for extension into automated tests of cognitive function, as well.

Estimating The Impact Of Assessment And Treatment Fidelity On Aphasia Treatment Outcomes, Trisha L. Tanaka

Speech and Hearing Sciences ETDs

Purpose: Calls for treatment and assessment fidelity strongly suggest the need to reduce treatment provider and assessor variance surrounding intervention research. The extent to which these sources of variance influence treatment outcomes in aphasia treatment research has yet to be examined. This simulation study sought to explore the relationships between quality of fidelity methods, sample size, power to detect treatment effects, and aphasia treatment effect sizes.

Methods: Individual participant outcomes collected from previous aphasia treatment research studies were used to simulate 200,000 participant outcomes, from which 8,000 sample treatment trials were simulated. Effect sizes were calculated for treatment outcomes related …

Development Of Kinematic Templates For Automatic Pronunciation Assessment Using Acoustic-To-Articulatory Inversion, Deriq K. Jones

Master's Theses (2009 -)

Computer-aided pronunciation training (CAPT) is a subcategory of computer-aided language learning (CALL) that deals with the correction of mispronunciation during language learning. For a CAPT system to be effective, it must provide useful and informative feedback that is comprehensive, qualitative, quantitative, and corrective. While the majority of modern systems address the first 3 aspects of feedback, most of these systems do not provide corrective feedback. As part of the National Science Foundation (NSF) funded study “RI: Small: Speaker Independent Acoustic-Articulator Inversion for Pronunciation Assessment”, the Marquette Speech and Swallowing Lab and Marquette Speech and Signal Processing Lab are conducting a …

The Impact Of Dysphagia On Quality Of Life And Stigma In Hispanic New Mexicans, Aaron Padilla

Speech and Hearing Sciences ETDs

INTRODUCTION: Eating is a function of daily life and is the centerpiece of family gatherings, business meetings, and holiday/religious traditions. Dysphagia (difficulty swallowing), can abolish the pleasure of mealtimes, which can negatively impact quality of life (QOL) and result in stigma. These variables may be influenced by cultural perceptions and/or acculturation, which is a measure of the impact that one cultural group has on another. The purpose of this investigation was to: a) identify the relationship between level of acculturation and QOL and stigma for Hispanics, b) measure the relationship between dysphagia severity and QOL and stigma, and c) explore …

Perceptual Differences In Natural Speech And Personalized Synthetic Speech, Katherine Overton

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine what perceptual differences existed between a natural recorded human voice and a synthetic voice that was created to sound like the same voice. This process was meant to mimic the differences between a voice that would be used for Message Banking and a voice that would be created by the ModelTalker system. Forty speech pathology graduate students (mean age = 23 years) rated voices on clarity, naturalness, pleasantness, and overall similarity. Analysis of data showed that the natural human voice was consistently rated as more natural, clear, and pleasant. In addition, participants …

It’S All About Context: Investigating The Effects Of Consonant And Vowel Environment On Vowel-Evoked Envelope Following Responses, Emma Bridgwater

Electronic Thesis and Dissertation Repository

The envelope following response (EFR) has proven useful for studying brainstem speech processing. Previous work, however, demonstrates that its amplitude varies across stimuli. This thesis investigates whether this variation is attributable to the consonant or vowel context of the stimulus, or some interaction of the two. Experiment 1 evoked EFRs in 30 participants using seven English vowels embedded in four CVC environments. A strong effect of vowel and a minor effect of consonant on EFR amplitude were found. In Experiment 2, 64 listeners heard four different tokens of one of four possible English vowels (16 participants/vowel), embedded in the same …

Validity Of A New Measure Of Phonemic Awareness That Does Not Require Spoken Responses In Children With Complex Communication Needs, Tiffany Chavers

USF Tampa Graduate Theses and Dissertations

Children with complex communication needs (CCN) routinely have difficulty attaining appropriate literacy skills. Two indicators of literacy development are the alphabetic principle and phonemic awareness (Byrne & Fielding-Barnsley, 1989). The acquisition of minimal literacy skills such as letter sound knowledge can give children with CCN the opportunity to communicate and generate their own messages, instead of being reliant on vocabulary provided by others. In order to identify appropriate intervention approaches, nonverbal assessments of phonological and phonemic awareness for individuals with CCN are needed.

The purpose of this study was to determine the reliability of the Dynamic Assessment of the Alphabetic …

"Marie Manje La Pom Nan." Examining The Cognitive Process Of Restructuring And Advantage Selection In The Definite Article System In Haitian Creole Among U.S. Born Heritage Speakers Of Haitian Creole, Marie-Michelle Monéreau-Merry

Dissertations, Theses, and Capstone Projects

The distributional patterns of heritage speakers’ reanalyzed first language are often grammatically divergent from native speakers. Irrespective of the heritage language, there is converging evidence that the cognitive process of reanalysis of heritage languages is often evident in less salient properties of the language, such as inflectional morphology (Polinsky & Kagan, 2007). Therefore, Haitian Creole (HC) is a candidate for restructuring. In this investigation we compared the morphophonological patterns of the definite article system at the production and perception level between two groups of early learners of Haitian Creole (i.e. native speakers vs. United States (US) born heritage speakers).

The …

The Relationship Between Fundamental Frequency Variation And Articulation In Healthy Speech Production, Casey Behre

Senior Honors Projects, 2010-2019

Fundamental Frequency (F0) and articulation are two factors of speech production that impact speech perception, and yet the potential interactions of these two factors are not well understood. Their relationship has potential theoretical as well as clinical implications. This Honors Project aims to better understand this relationship by examining changes in fundamental frequency (F0) and the acoustic vowel space as an index of articulatory behaviors with a within-speaker approach. Specifically, F0 variations were examined in relation to the acoustic vowel space for 10 male native speakers of American English. Two sets of acoustic measures were made to evaluate F0 and …

The Effects Of Age On The Perception Of Frequency In Noise, Mary E. Scherer

Dissertations, 2014-2019

Difficulty understanding speech in the presence of background noise is one of the most common complaints of older adults, both with and without hearing loss. One possible contributing factor is an age-related decline in neural synchrony (e.g., phase locking). Tones-in-noise were used in an attempt to disrupt rate-place coding of frequency and to encourage participants to use phase-locked, temporal representations of frequency during a behavioral frequency discrimination task. Fourteen adults participated in the study (five younger, aged 21-29; four middle aged, 41-50; and five older, aged 61-80). Participants had clinically normal hearing sensitivity (≤ 25 dB HL at octave frequencies …

All of the children readily understood the single-note pitch perception task. Pitch contrast performance across participants ranged from 50% to 96% correct for the first data collection period and …

An Internationally Adopted Child's Transition: A Family Story, Holly C. Heckmann

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

The goal of this study was to contribute to the literature on international adoption by conducting a case study with one adoptive family. Data was collected using a semi-structured, in-depth interview that was audio recorded and transcribed word-for-word. The interview questions asked about family configuration, language background and use, adoptive family decisions about cultural inclusiveness, and the transition from home to school. The analysis was member-checked following coding for the themes that emerged. Results indicated that lingering differences from reduced exposure to language in the first year of life took the form of subtle language differences that continued through the …

Automatic Activation Of Phonological Templates For Native But Not Nonnative Phonemes: An Investigation Of The Temporal Dynamics Of Mu Activation, Daniela Cristina Santos-Oliveira

Theses and Dissertations (ETD)

Models of speech perception suggest a dorsal stream connecting the temporal and inferior parietal lobe with the inferior frontal gyrus. This stream is thought to involve an auditory-motor loop that translates acoustic information into motor/articulatory commands and is further influenced by decision making processes that involve maintenance of working memory or attention. Parsing out dorsal stream’s speech specific mechanisms from memory related ones in speech perception poses a complex problem. Here I argue that these processes may be disentangled from the viewpoint of the temporal dynamics of sensorimotor neural activation around a speech perception related event.

Methods: Alpha (~10Hz) and …

Improving Access To Communication For Adults With Aphasia Using "Aphasia-Friendly" Accommodations, Chandler Hodgkin

Honors Theses

Accessing written health information is vital to any health visit (Blackstone, Beukelman, & Yorkston, 2015). People who have difficulty comprehending written text have difficulty understanding health-related information because it is usually written at a complex levels (Kanj & Mitic, 2009). If health information contains complicated content and is not easily accessible, people may not receive the health care needed (Blackstone et al., 2015). Many populations are considered communication vulnerable relative to health care which means they may not have access to understanding health information documents (Hallowell, 2016). These populations include people who are blind or visually impaired; people who are …

The Effect Of Clinical Experience On Perceived And Self-Reported Empathy In Novice Speech- Language Pathology Clinicians, Erline Vieira Nakano

USF Tampa Graduate Theses and Dissertations

In the field of medicine, empathic providers have been found to bring numerous benefits to a clinical encounter as they are better able to elicit detailed and thorough case histories, build rapport and therapeutic alliance with patients, and foster greater compliance with treatment recommendations. Despite its multiple benefits, empathy has not been researched systematically within the field of speech-language pathology. In medical training, empathy has been found to decline by the time medical students are introduced to direct patient care. Currently, no information is available regarding the empathy trajectory of novice speech-language pathologists.

The goal of the current project was …

Perceived Stress, Self-Compassion, And Emotional Variance In Parents Of Children With Communication Disorders: A Family Approach To Service Delivery In Speech-Language Pathology, Olivia Marie Arnos

Theses and Dissertations

The amount of children born with developmental disorders in the United States is on the rise, increasing from 12.8% in 1998 to 15.04% in 2008 (Huang, Chang, Chi & Lai, 2013). Children with developmental disabilities often have chronic conditions that require additional support across their lifetime, ranging in deficits of attention, physical abilities, visual impairments, hearing impairments, learning disabilities, and communication disorders. Research has shown as dependency of a child on caretakers increases, there is an increase in parental stress and a decrease in perceived well-being. Hall and Graff (2011) found parents of children with developmental disorders are less likely …
