Aerodynamic And Acoustic Features Of Vocal Effort, Allison Rosenthal

Speech-Language Pathology - Theses

Many voice disorders are associated with an effortful voice; however, there have been very few studies that have examined the physiological changes that contribute to this sense of effort. Determining the factors that contribute to change in vocal effort may help clinicians to effectively target these variables when working with people with voice disorders so that voice improvement is accompanied by decreased vocal effort after treatment. Prior research has shown that alterations in aerodynamic and acoustic variables are often associated with voice disorders involving increased muscular effort, and change in these variables is correlated with abnormal voice qualities. The current …

A Comparison Of Caregiver And Speech-Language Pathologist's Ratings Of Speech Outcome In Oral Cleft Clinic, Emily Swain

Honors Theses

Background: Cleft lip and/or palate is one of the most common congenital anomalies. The goal of treatment of cleft palate is normal speech, but a proportion of children with clefts exhibit speech disorders. Various outcome measures are used, but relatively few have focused on self-assessment or caregiver perception of outcome. The studies that have been done focus on comparing parents' and speech-language pathologists' ratings of speech outcome. These studies can be used to determine the degree to which caregivers are satisfied with speech outcome over time.

Purpose: The purpose of this study was to describe the relationship between speech ratings …

The Measurement Of Auditory Interhemispheric Transfer Time (Ihtt) In Children With Normal Auditory Processing Abilities, Brittany Suzanne Keahey

Doctoral Dissertations

Interhemispheric transfer time (IHTT) is the time it takes for information to be transmitted from one hemisphere to the other. The goal of this study was to determine if differences existed in the IHTT of children 6 to 9 years of age with normal auditory processing abilities by the use of an objective measure (auditory late evoked potentials [ALEPs]), specifically waves P1, N1 and P2. It was hypothesized that there would be no difference in IHTT between the groups due to the age range of participants being tested. The 16 participants were divided into two groups based on age and …

Asymmetrical Speech In Noise Assessment For Children With (Central) Auditory Processing Disorders, Jessica Vaughn

Doctoral Dissertations

The primary purpose of this investigation was to determine if children with (Central) Auditory Processing Disorder have better word recognition abilities for monosyllabic words under monaural speech-in-noise conditions than binaural speech-in-noise conditions. Fifteen participants, five females and ten males, ages 8-10 years, were included in this study. There were 7 children placed in the experimental group with a diagnosis of (C) APD identified from the Louisiana Tech University Speech and Hearing Center. There were 8 typically developing children placed in the control group. Each participant had pure-tone thresholds of 0-20 dB HL for 250-8000 Hz bilaterally. The SCAN-3 for children, …

Effects Of Untrained Earmold Impression Taking On Custom Hearing Protector Device Performance, Kelly R. Pack

Doctoral Dissertations

Today's consumer is increasingly turning to the internet for both healthcare information as well as the purchase of custom hearing protection devices (HPDs). These HPDs are often cast from do-it-yourself home ear impression kits that include a syringe and silicone earmold impression material to be injected into the ear canal. Although not required by law, earmold impressions have typically been taken by medical professionals and other individuals formally trained in the procedures and safety measures of effective earmold impression taking. The main purpose of this study was to determine if do-it-yourself earmold impressions produce HPD's with lower attenuation levels than …

Preschoolers With Speech And Language Impairment: Case Studies From A Teacher-Delivered Phonological Awareness Program, Katherine J. Wickham

Masters Theses

Past and present research demonstrates early reading success related to phonological awareness (PA) instruction conducted individually or in small groups outside of the preschool classroom. This study investigated the effects of an explicit, intensive and teacher-delivered PA instruction for children with speech sound disorder and language impairment as part of the preschool curriculum. The investigator examined the performance of individual cases in both groups, those who received instruction and the control. Two participants in each of the experimental (E1 and E2) and control (C1 and C2) groups had standardized scores indicating deficits in speech and/or language. These children who received …

Effects Of Aging And Spectral Shaping On The Sub-Cortical (Brainstem) Differentiation Of Contrastive Stop Consonants, Dania A. Rishiq

Theses and Dissertations (ETD)

Purpose: The objectives of this dissertation are to: (1) evaluate the influence of aging on the sub-cortical (brainstem) differentiation of voiced stop consonants (i.e. /b-d-g/); (2) determine whether potential aging deficits at the brainstem level influence behavioral identification of the /b-d-g/ stimuli, (3) investigate whether spectral shaping diminishes any aging impairments at the brainstem level; and (4) if so, whether minimizing these deficits improves the behavioral identification of the speech stimuli.

Subjects: Behavioral and electrophysiological responses were collected from 11 older adults (> 50 years old) with near-normal to normal hearing and were compared to those of 16 normal-hearing younger …

Communication Disorders Faculty Publications

Velocardiofacial and DiGeorge syndromes, also known as 22q11.2 deletion syndrome (22q11DS), are congenital-anomaly disorders caused by a de novo hemizygous 22q11.2 deletion mediated by meiotic nonallelic homologous recombination events between low-copy repeats, also known as segmental duplications. Although previous studies exist, each was of small size, and it remains to be determined whether there are parent-of-origin biases for the de novo 22q11.2 deletion. To address this question, we genotyped a total of 389 DNA samples from 22q11DS-affected families. A total of 219 (56%) individuals with 22q11DS had maternal origin and 170 (44%) had paternal origin of the de novo deletion, …

Hearing Loss In The Dental Office: The Effects Of High Speed Dental Drills On Dentists' Hearing, Krisztina Johnson, Jacek Smurzynski, Saravanan Elangovan, Marc Fagelson

ETSU Faculty Works

Hearing test results of 23 dentists obtained before and after working hours are compared to determine if dentists experience any temporary hearing loss. The aim of the project is to determine whether dental drills cause hearing loss and to document the consequences of the loss. Hearing evaluations include pure-tone audiometry, middle-ear testing, and measurements of otoacoustic emissions. The results are expected to convince dentists of the danger of noise exposure and the need for hearing protection

Modeling Hrtf For Sound Localization In Normal Listeners And Bilateral Cochlear Implant Users, Douglas A. Miller

Electronic Theses and Dissertations

Mathematical models can be very useful for understanding complicated systems and for testing algorithms through simulation that would be difficult or expensive to implement. This dissertation presents a model that attempts to simulate the sound localization performance of persons using bilateral cochlear implants. The expectation is that this model could prove to be a useful tool in developing new signal processing algorithms for neural encoding strategies.

The head related transfer function (HRTF) is a critical component of this model, and in the ideal case, provides the base characteristics of head shadow, torso and pinna effects. This defines the temporal, intensity …

Time-Frequency Analysis Of Transient-Evoked Otoacoustic Emissions In Children Exposed To Carboplatin Chemotherapy, Shaum Bhagat, Johnnie Bass, Ibrahim Qaddoumi, Rachel Brennan, Matthew Wilson, Jianrong Wu, Carlos-Rodriguez Galindo, Alessia Paglialonga, Gabriella Tognola

Faculty Publications

The aims of this study were to characterize and quantify time-frequency changes in transient-evoked otoacoustic emissions (TEOAEs) recorded in children diagnosed with retinoblastoma who were receiving carboplatin chemotherapy. A signal processing technique, the wavelet transform (WT), was used to analyze TEOAE waveforms in narrow-band frequency components. Ten children (aged 3–72 months) diagnosed with unilateral or bilateral retinoblastoma were enrolled in the study. TEOAEs were acquired from the children with linear sequences of 70 dB peak equivalent SPL clicks. After WT analysis, TEOAE energy, latency and normalized energy in the narrow-band frequency components were compared before and during carboplatin chemotherapy treatment …

Women Who Stutter : Experiences Of Developing Self-Management And Quality Of Life, Katherine Milton

Theses : Honours

Background and Purpose: Research suggests that stuttering can impact an individual’s quality of life and how they perceive themselves in interactions with others. As a larger proportion of adults who stutter are men, limited research is available regarding the specific experiences of women who stutter (WWS). Existent literature regarding WWS was mainly published in the 1970s -1980s and may no longer represent current issues. This study aimed to explore the current influences on quality of life, perception of stuttering, self-management strategies, and gender issues experienced by WWS.

Methods and Procedures: This grounded theory study used a convenience sample of eight …

Age-Related Changes To The Production Of Linguistic Prosody, Daniel Richard Barnes

Open Access Theses

The production of speech prosody (the rhythm, pausing, and intonation associated with natural speech) is critical to effective communication. The current study investigated the impact of age-related changes to physiology and cognition in relation to the production of two types of linguistic prosody: lexical stress and the disambiguation of syntactically ambiguous utterances. Analyses of the acoustic correlates of stress: speech intensity (or sound-pressure level; SPL), fundamental frequency (F0), key word/phrase duration, and pause duration revealed that both young and older adults effectively use these acoustic features to signal linguistic prosody, although the relative weighting of cues differed by group. Differences …

Preschool Language And Phonological Proficiencies In Predicting Stuttering Recovery Or Persistence, Caroline E. Spencer

Open Access Theses

The purpose of this study was to investigate the relationship between expressive and receptive language, phonological, and verbal working memory proficiencies in the preschool years and eventual recovery from or persistence in stuttering. Participants included 40 children who stutter (CWS). At ages 3-5 years, participants were administered the Test of Auditory Comprehension of Language, 3rd edition (TACL-3), the Structured Photographic Expressive Language Test, 3rd edition (SPELT-3), Bankson-Bernthal Test of Phonology--Consonant Inventory subtest (BBTOP--CI), Test of Auditory Perceptual Skills--Revised (TAPS--R) auditory number memory and auditory word memory subtests, and the Dollaghan & Campbell Nonword Repetition Test (NRT). Stuttering behaviors were tracked …

Self-Ratings Of Communication Style And Discourse Performance Of Healthy Aging Adults, Hayley E. Besten

Theses and Dissertations--Communication Sciences and Disorders

This study investigated the accuracy of healthy aging adults‟ self-rating of communication style, as measured by quantifiable measures of discourse performance. Ninety cognitively healthy adults participated and comprised three age cohorts (20s, 40s, 60s). Participants completed discourse tasks that included recounting a vacation, telling a story, and describing a picture. Participants also self-rated their communication style, placing them in a talkative or reserved cohort. Communication style was measured by discourse performance variables of interest: length of output (TNW) and informativeness (%IU). When presented with an unconstrained task (recounting a vacation), talkative and reserved groups, regardless of age, produced a similar …

Personalizing Aac For People With Aphasia: The Role Of Text And Pictures, Aimee R. Dietz, Kristy S.E. Weissling, Julie Griffith, Miechelle L. Mckelvey

Department of Special Education and Communication Disorders: Faculty Publications

Over time, and with intensive instruction, people with aphasia (PWAs) can learn to use grid-based, categorically organized, high-technology AAC layouts during structured tasks (e.g., Hough & Johnson, 2009). In an effort to reduce the training intensity required to teach PWAs to use AAC; researchers developed visual scene displays (VSDs), designed to complement the residual cognitive and linguistic abilities of PWAs by tapping their intact episodic memory. VSD interfaces incorporate personally relevant (PR) photos, text, and speech output (Dietz, McKelvey, & Beukelman, 2006; Weissling & Beukelman, 2006). VSDs appear to facilitate improved communication success (e.g., McKelvey, Dietz, Hux, Weissling, & Beukelman, …

Electropalatography As An Adjunct To Nonspeech Orofacial Myofunctional Disorder Assessments: A Feasibility Study, Alana Mantie-Kozlowski, Kevin M. Pitt

Department of Special Education and Communication Disorders: Faculty Publications

The purpose of this study was to determine if electropalatography (EPG) would be a useful adjunct and feasible option for those conducting clinical assessments of individuals with suspected nonspeech orofacial myofunctional disorders (NSOMD). Three females (two adults, one child) were referred by their orthodontist for assessment of suspected NSOMD. Three adults and one child without NSOMD were recruited for the purpose of evaluating methodological construct, and to provide comparisons for participants with NSOMD. Using EPG, lingual-palatal timing and contact patterns of 105 saliva swallows (45 with NSOMD, 60 without NSOMD) were analyzed by compartmentalizing the sensor display and tracking the …

Comparing Spoken Language Treatments For Minimally Verbal Preschoolers With Autism Spectrum Disorders, Rhea Paul, Daniel Campbell, Kimberly Gilbert, Ioanna Tsiouri

Communication Disorders Faculty Publications

Preschoolers with severe autism and minimal speech were assigned either a discrete trial or a naturalistic language treatment, and parents of all participants also received parent responsiveness training. After 12 weeks, both groups showed comparable improvement in number of spoken words produced, on average. Approximately half the children in each group achieved benchmarks for the first stage of functional spoken language development, as defined by Tager-Flusberg et al. (J Speech Lang Hear Res, 52: 643–652, 2009). Analyses of moderators of treatment suggest that joint attention moderates response to both treatments, and children with better receptive language pre-treatment do better with …

Acoustic And Perceptual Measurements Of Prosody Production On The Profiling Elements Of Prosodic Systems In Children By Children With Autism Spectrum Disorders, Joshua John Diehl, Rhea Paul

Communication Disorders Faculty Publications

Prosody production atypicalities are a feature of autism spectrum disorders (ASDs), but behavioral measures of performance have failed to provide detail on the properties of these deficits. We used acoustic measures of prosody to compare children with ASDs to age-matched groups with learning disabilities and typically developing peers. Overall, the group with ASD had longer utterance durations on multiple subtests on a test of prosodic abilities, and both the ASD and learning disabilities groups had higher pitch ranges and pitch variance than the typically developing group on one subtest. Acoustic differences were present even when the prosody was used correctly.These …

Vowel Production In Mandarin Accented English And American English: Kinematic And Acoustic Data From The Marquette University Mandarin Accented English Corpus, An Ji, Jeffrey J. Berry, Michael T. Johnson

Speech Pathology and Audiology Faculty Research and Publications

Few electromagnetic articulography (EMA) datasets are publicly available, and none have focused systematically on non-native accented speech. We introduce a kinematic-acoustic database of speech from 40 (gender and dialect balanced) participants producing upper-Midwestern American English (AE) L1 or Mandarin Accented English (MAE) L2 (Beijing or Shanghai dialect base). The Marquette University EMA-MAE corpus will be released publicly to help advance research in areas such as pronunciation modeling, acoustic-articulatory inversion, L1-L2 comparisons, pronunciation error detection, and accent modification training. EMA data were collected at a 400 Hz sampling rate with synchronous audio using the NDI Wave System. Articulatory sensors were placed …

Speech Sensorimotor Learning Through A Virtual Vocal Tract, Jeffrey J. Berry, Cassandra North, Benjamin Meyers, Michael T. Johnson

Speech Pathology and Audiology Faculty Research and Publications

Studies of speech sensorimotor learning often manipulate auditory feedback by modifying isolated acoustic parameters such as formant frequency or fundamental frequency using near real-time resynthesis of a participant's speech. An alternative approach is to engage a participant in a total remapping of the sensorimotor working space using a virtual vocal tract. To support this approach for studying speech sensorimotor learning we have developed a system to control an articulatory synthesizer using electromagnetic articulography data. Articulator movement data from the NDI Wave System are streamed to a Maeda articulatory synthesizer. The resulting synthesized speech provides auditory feedback to the participant. This …

Supporting Narrative Retells For People With Aphasia Using Aac: Photographs Or Line Drawings? Text Or No Text?, Julie Griffith, Aimee R. Dietz, Kristy S.E. Weissling

Department of Special Education and Communication Disorders: Faculty Publications

People with aphasia (PWAs) have demonstrated the ability to learn augmentative and alternative communication (AAC) devices that employ traditional grid layouts to enhance their communication; however, the process is typically lengthy and yields limited generalization (Fox & Fried-Oken, 2001; Koul & Harding, 1998). In response, researchers have begun to investigate the use of visual scene displays (VSDs) to support the communication interactions of PWAs by capitalizing on their relatively intact episodic memory (Beukelman, Dietz, McKelvey, Hux, & Weissling, in press; Dietz, Beukelman, & McKelvey, 2006a; Dietz, McKelvey, Beukelman, Weissling, & Hux, 2006b; McKelvey, Dietz, Hux, Weissling, & Beukelman, 2007). High-technology …
