Relationship Between Acoustic Measures And Speech Naturalness Ratings In Parkinson’S Disease: A Within-Speaker Approach, Marie I. Klopfenstein

SIUE Faculty Research, Scholarship, and Creative Activity

This study investigated the acoustic basis of across-utterance, within-speaker variation in speech naturalness for four speakers with dysarthria secondary to Parkinson’s disease (PD). Speakers read sentences and produced spontaneous speech. Acoustic measures of fundamental frequency, phrase-final syllable lengthening, intensity and speech rate were obtained. A group of listeners judged speech naturalness using a nine-point Likert scale. Relationships between judgements of speech naturalness and acoustic measures were determined for individual speakers with PD. Relationships among acoustic measures also were quantified. Despite variability between speakers, measures of mean F0, intensity range, articulation rate, average syllable duration, duration of final syllables, vocalic nucleus …

The Impact Of Lingual Resistance Training In Two Individuals With Amyotrophic Lateral Sclerosis: A Case Series, Raele Donetha Robison

USF Tampa Graduate Theses and Dissertations

Introduction: Amyotrophic Lateral Sclerosis (ALS) is a fatal and progressive disease characterized by the deterioration of motor neurons within the body. This degeneration leads to bulbar dysfunction in the form of an impaired ability to communicate and swallow. Currently, bulbar dysfunction is treated via compensatory methods aimed at maximizing comfort and safety that include environmental adaptations, augmentative and assistive communication and gastrostomy tube placement to replace speech and oral feeding. The role of active intervention is controversial in this patient population and no investigations have examined the potential role lingual exercise might play in ALS bulbar management. The purpose of …

Validity Of A Nonspeech Dynamic Assessment Of Phonological Awareness In Children From Spanish-Speaking Backgrounds, Bianca Angelica Loreti

USF Tampa Graduate Theses and Dissertations

Literacy development in Spanish-speaking children is a growing concern in the United States (Invernizzi, 2009). Phonological awareness is a predictor of literacy achievement in most alphabetic languages (Anthony et al., 2011; Davison & Brea-Spahn, 2012; Durgunoğlu, Nagy, & Hancin-Bhatt, 1993; Goikoetxea, 2005). Bilingual children with complex communication needs (CCN) demonstrate increased difficulties in speaking, reading, and writing, making learning two languages a difficult task (Toppelberg, Snow, & Tager-Flusberg, 1999). Literacy attainment in bilingual individuals who have CCN is important to improve their overall language development and communication interaction skills (Harrison-Harris, 2002). A valid and reliable phonological awareness assessment that does …

Towards An Automated Screening Tool For Pediatric Speech Delay, Roozbeh Sadeghian, Stephen A. Zahorian

Faculty Works

Speech delay is a childhood language problem that sometimes is resolved on its own but sometimes may cause more serious language difficulties later. This leads therapists to screen children for detection at early ages in order to eliminate future problems. Using the Goldman-Fristoe Test of Articulation (GFTA) method, therapists listen to a child's pronunciation of certain phonemes and phoneme pairs in specified words and judge the child's stage of speech development. The goal of this paper is to develop an Automatic Speech Recognition (ASR) tool and related speech processing methods which emulate the knowledge of speech therapists. In this paper …

Counseling Training For Audiology Students: Using Standardized Patients, Catherine Schroy

Arts & Sciences Graduate Student Theses and Dissertations

The implementation of Universal Newborn Hearing Screening (UNHS) has resulted in earlier diagnosis of hearing loss in children. Research shows that early diagnosis of hearing loss results in better outcomes in speech and language, socio-emotional, and cognitive development. Early diagnosis, however, often comes as a surprise to parents of newborns. When parents are told their child has a hearing loss, it is often before they have been able to observe behaviors that would lead to the suspicion of hearing loss. Parents are usually told about the hearing loss diagnosis by an audiologist and are often dissatisfied with how the news …

Research has also shown a decline in processing speed as age increases. The present study seeks to answer the following questions: 1. Will background vocal music have any detrimental effects on performance of a visual semantic word categorization task? 2. Does age have any effect on performance of visual semantic word categorization in the presence of background music?

Participants: Participants consisted of 36 adult native speakers of English with normal speech and language divided in to two groups based on …

Training And Application Of Correct Information Unit Analysis To Structured And Unstructured Discourse, Audrey Bretthauer Cohen

Dissertations and Theses

Correct Information Units (CIU) analysis is one of the few measures of discourse that attempts to quantify discourse as a function of communicating information efficiently. Though this analysis is used reliably as a research tool, most studies' apply CIUs to structured discourse tasks and do not specifically describe how raters are trained. If certified clinical speech-language pathologists can likewise reliably apply CIU analysis within clinical settings to unstructured discourse, such as the discourse of people with aphasia (PWA), it may allow clinicians to quantify the information communicated efficiently in clinical populations with discourse deficits. Purpose: The purpose of this study …

the startle reflex as the response for detecting the sound stimulus. The goal of

Dr. Klingenberg’s AuD project was “to explore the methodological, functional, and

genetic influences on sound localization using pre-pulse inhibition of the acoustic

startle response in mice”. Dr. Klingenberg’s project was broken into three …

Binaural Listening In Young And Middle-Aged Adults: Interaural Phase Differences And Speech-In-Noise Measures, Caitlin Cotter

Dissertations, 2014-2019

Difficulty understanding speech in the presence of noise is a common complaint of middle-aged and older adults with and without hearing loss. There is an incomplete picture of what contributes to difficulties understanding speech-in-noise in adults who have normal audiograms. As humans we listen binaurally, so declines in binaural processing may contribute to speech-in-noise difficulties. We examined the effects of age on the upper frequency limit of interaural phase difference (IPD) detection and IPD detection at fixed frequencies. We also examined a speech-in-noise measure of spatial separation across young and middle-aged, normal-hearing individuals.

Participants were young (n=12) and middle-aged (n=8) …

Effects Of Training And Lung Volume Levels On Voice Onset Control And Cortical Activation In Singers, Nicholas A. Barone

Dissertations, 2014-2019

Singers need to counteract respiratory elastic recoil at high and low lung volume levels (LVLs) to maintain consistent airflow and pressure while singing. Professionally trained singers modify their vocal and respiratory systems creating a physiologically stable and perceptually pleasing voice quality at varying LVLs. In manuscript 1, we compared non-singers and singers on the initiation of a voiceless plosive followed by a vowel at low (30% vital capacity, VC), intermediate (50%VC), and high (80%VC) LVLs. In manuscript 2, we examined how vocal students (singers in manuscript 1) learn to control their voice onset at varying LVLs before and after a …

Pre-Pulse Inhibition Assessment Of Sound Localization In Mice: Methodological, Functional, And Genetic Considerations, Megan Klingenberg

Dissertations, 2014-2019

Sound localization is an important aspect of normal hearing. The Eph/ephin family of signaling proteins, studied here, is known to guide the formation of central auditory connections in early development, particularly topographic inputs from the lateral superior olive (LSO) to the inferior colliculus (IC). Processing in the LSO and its influences on the IC are known to be heavily involved in sound localization tasks. One way to study sound localization in mice is through pre-pulse inhibition (PPI). PPI is the phenomenon by which a weak prestimulus inhibits the response to a subsequent startle stimulus. In studying sound localization, the prestimulus …

Examining Monaural And Binaural Measures Of Phase-Locking As A Function Of Age, Larissa M. Heckler

Dissertations, 2014-2019

Understanding speech in the presence of background noise is a common complaint of middle-aged and older listeners with clinically normal audiograms. There is great interest in understanding how age-related changes in auditory physiology make it harder for older adults to understand speech in difficult listening situations, compared to young listeners. It was recently reported that middle-aged and older normal-hearing listeners showed frequency-dependent, age-related declines in the behavioral and physiological detection of interaural phase differences (Grose & Mamo, 2010; Ross et al, 2007). There is also evidence of an age-related, frequency-dependent decline in the frequency-following response (FFR) (Clinard et al., 2010), …

The Discrimination Of Cv Synthetic Syllables As A Function Of Phonetic Training And Noise Conditions, Ryan Mulligan, Antony Joseph

AuD Capstone Projects - Communication Sciences and Disorders

The aim of this preliminary study was to examine the effect of two signal-to-noise ratios (SNR) and formal phonetic training on auditory discrimination of just noticeable differences (JND) among consonant vowel (CV) synthetic syllables. Fine-grain auditory discrimination abilities of 16 young-adults with undergraduate studies that included phonetic training and 17 young-adults with no phonetic training were assessed using a same/different discrimination task in a +3 SNR and a +13 SNR listening condition. Subjects listened to pairs of CV contrasts presented in rapid succession and indicated whether the contrastive syllables were the same or different. Results revealed a significant difference …

Central Auditory Processing And The Link To Reading Ability In Adults, Lisa M. Brody

Honors Scholar Theses

What makes someone a good reader? What makes someone a poor reader? The root biological marker of reading ability has yet to be determined. Many scientists agree that phonological awareness, the understanding of speech sounds, and phonological decoding are key components of reading ability (Melby-Lervag, Lyster, & Hulme, 2012). In addition to this, new research suggests that the auditory system, specifically the timing of auditory processing in the brain, provides a crucial platform that supports the development of reading ability (Banai et al., 2009). This thesis provides empirical data to support the link between reading skill …

Bridging Theories Of Phonological Awareness For Deaf And Hard Of Hearing Children: Perspectives From Verbotonal Specialists In The United States, Jazmin Rambeau

Honors Theses

Approaching literacy instruction for children who are deaf and hard of hearing is one of the most significant challenges within global education because there are various evidence-based theories in the literature as to why children who are deaf and hard of hearing often manifest impaired reading abilities compared to children with normal hearing, and how they may acquire literacy skills differently. This study aims to identify agreements within the literature regarding the role of phonological awareness in literacy acquisition for children who are deaf and hard of hearing, and how tools such as the Verbotonal method of auditory therapy may …

A Call For Hearing Loss Prevention Programs In College Music Education Programs, Jason Taurins

Honors Theses

Music educators, ensemble conductors, and students who participate in musical ensembles are exposed to sound pressure levels which exceed the criteria for NIOSH. As such, this population should be enrolled in hearing loss prevention programs. Ensemble directors (many music educators fall into this category) have a direct role in influencing the sound pressure levels produced in rehearsals. Music educators have a role in influencing the knowledge, skills, attitudes, and behaviors of their students. Because of the health risks of noise exposure, and the role music educators (and ensemble directors in general) have in influencing their students, hearing loss prevention should …

Stakeholder Perspectives Of The Effectiveness Of Augmentative And Alternative Communication Techniques In Children With Autism, Daria Constantinescu

Theses and Dissertations

The purpose of this study was to utilize focus groups and individual interviews to investigate the effectiveness and efficiency of augmentative and alternative (AAC) techniques in facilitating language in children with Autism Spectrum Disorder (ASD) as expressed by the opinions and attitudes of stakeholders involved in the process. ASD is a disorder that affects an individual's social and communication skills that usually surfaces within a child's first three years of life. There have been numerous studies conducted comparing different types of AAC intervention systems, but there is little information on stakeholders' opinions. The current study utilized one focus group interview …

Noise Induced Hearing Loss: The Impact Of Acoustic Trauma On The Ear, Aviva Levihaiem

The Science Journal of the Lander College of Arts and Sciences

Noise-induced hearing loss (NIHL) is a pervasive disability that affects millions of people across the world. It is characterized by a decrease in hearing sensitivity to sounds that fall between 3000–6000 Hz(known as the “notch”). NIHL is caused by either a sudden acoustic trauma or long-term exposure to noise levels above 85 dB. The noise exposure induces overproduction of free radicals within the cells of the cochlea, overpowering of the ear’s antioxidant defense systems. The free radicals then destroy cell membranes and hair cell nuclei, causing necrosis and apoptosis, leading to hair cell death. This upsets the mechanical structure and …

Examining Barriers With Implementing Augmentative And Alternative Communication In A Midwest School, Ashley Renee Fields

Walden Dissertations and Doctoral Studies

Many speech-language pathologists (SLPs) in a Midwest urban public school system have experienced barriers that prohibit the effective use of augmentative and alternative communication (AAC). The result has left some students with speech language impairments (SLI) without the communication skills for meaningful relationships and success in and out of school. The purpose of this exploratory case study was to determine the perceived barriers of 8 local school SLPs regarding the successful implementation of AAC and their suggestions for addressing the problem. Data were collected from semi-structured interviews with the SLPs. Data collection and analysis were grounded by Ely's conditions of …

The Contribution Of Mild Traumatic Brain Injury/Concussion To The Development Of Post-Traumatic Stress Disorder Symptoms, Kylie Lauren Marshall

Open Access Theses & Dissertations

A controversial issue is whether TBI is a necessary precursor to the development of PTSD symptoms, or if the two variables are mutually exclusive. Recent rodent-models reveal that a stressful environment cannot cause PTSD symptoms directly without TBI, yet it is unknown if PTSD symptoms can develop following a TBI. This study provides a potential analogue to study this relationship by evaluating the effects of sports-related concussion. Purpose: This study investigated two questions, 1) Is there a significant difference in the frequency of PTSD symptoms reported by athletes at baseline (BL) testing and post-concussion (PC) testing over time? 2) Is …

Processing Of Language Switches In Bilingual Individuals With Aphasia: An Event-Related Potential Comparison, Lizette Rodarte

Open Access Theses & Dissertations

Switching between languages, or code-switching, is a common phenomenon in bilingual individuals. In proficient bilinguals, these switches are done with ease and are used for many purposes. Contrary to popular belief, these switches are rule-governed and follow grammatical structure. Bilingual individuals diagnosed with aphasia present with difficulty processing languages and these language switches. With the increase in bilingual individuals, it is likely that the speech-language pathology community will see an increase of bilingual individuals with aphasia on their caseload. For this reason, the purpose of this study is to increase our understanding of the neural processes involved in processing of …
