The Effect Of Timbre And Vibrato On Vocal Pitch Matching Accuracy, Sirisha Duvvuru

Theses and Dissertations (ETD)

Research has shown that singers are better able to match pitch when the target stimulus has a timbre close to their own voice. This study seeks to answer the following questions: 1. Do classically trained female singers more accurately match pitch when the target stimulus is more similar to their own timbre? 2. Does the ability to match pitch vary with increasing pitch? 3. Does the ability to match pitch differ depending on whether the target stimulus is produced with or without vibrato? 4. Are mezzo sopranos less accurate than sopranos? Stimuli: Source signals were synthesized with a source slope …

Neural Underpinnings Of Prosody In Autism, Inge-Marie Eigsti, Jillian Schuh, Einar Mencl, Robert T. Schultz, Rhea Paul

Communication Disorders Faculty Publications

This study examines the processing of prosodic cues to linguistic structure and to affect, drawing on fMRI and behavioral data from 16 high-functioning adolescents with autism spectrum disorders (ASD) and 11 typically developing controls. Stimuli were carefully matched on pitch, intensity, and duration, while varying systematically in conditions of affective prosody (angry versus neutral speech) and grammatical prosody (questions versus statement). To avoid conscious attention to prosody, which normalizes responses in young people with ASD, the implicit comprehension task directed attention to semantic aspects of the stimuli. Results showed that when perceiving prosodic cues, both affective and grammatical, activation of …

Whole-Word Recognition From Articulatory Movements For Silent Speech Interfaces, Jun Wang, Ashok Samal, Jordan R. Green, Frank Rudzicz

Department of Special Education and Communication Disorders: Faculty Publications

Articulation-based silent speech interfaces convert silently produced speech movements into audible words. These systems are still in their experimental stages, but have significant potential for facilitating oral communication in persons with laryngectomy or speech impairments. In this paper, we report the result of a novel, real-time algorithm that recognizes whole-words based on articulatory movements. This approach differs from prior work that has focused primarily on phoneme-level recognition based on articulatory features. On average, our algorithm missed 1.93 words in a sequence of twenty-five words with an average latency of 0.79 seconds for each word prediction using a data set of …

Familiality Of Auditory Evoked Potentials: Preliminary Investigation Of The Auditory Brainstem Response And Late Latency Cortical Response, Matthew B. Lucas

Electronic Thesis and Dissertation Repository

Twenty-four participants, consisting of six sibling pairs and six non-sibling pairs, participated in this study investigating the familiality of auditory evoked potentials (AEPs). The auditory brainstem response (ABR) recorded at high stimulus rates, revealed that Wave V latency increases, while amplitude decreases as stimulus rate increases. ABR Wave V latency was also found to increase with click position within a stimulus train, plateauing by the third stimulus. No evidence for familiality was found with respect to the ABR Wave V under these conditions. The late latency response (LLR) components N1 and P2 were found to decrease between the first and …

Improving Literacy Through Instruction And Community Experiences: : The Effect Of A Summer Program On Literacy Outcomes Of Students From Low Ses Homes, Lisa Delozier Bowers

Theses and Dissertations (ETD)

Among the academic challenges faced by students from low socio-economic (SES) homes is the loss of academic skills during the summer months. Unfortunately, the public schools are often unable to provide summer learning opportunities because limited space, funding, and teacher availability. Established community organizations frequently provide summer programs, however, there is little research to indicate that they can be used to address summer learning loss.

A summer program was designed to improve oral and written narrative skills for students from low SES homes. This program was based in a local community ministry and was designed to use thematic units that …

An Exploratory Study Of Characteristics Associated With Postsecondary Educational Attainment In Students Who Are Deaf Or Hard Of Hearing, Amy Marie Hebert

Graduate Theses and Dissertations

It is well documented that attrition in the postsecondary settings for students who are deaf or hard of hearing is greatly due to their academic and communication skills, as well as pre-entry attributes. However there is little evidence that indicates why students who are deaf or hard of hearing are successful in the postsecondary setting. This study tested a hypothesis that demographic, family, psychological and educational variables have a relationship with postsecondary attainment. The variables included in the study were gender, race, math literacy, reading literacy, high school academic setting (public/residential), communication modality (sign language/oral speech), cochlear implant user, parental …

Independent Component Analysis Of Event-Related Electroencephalography During Speech And Non-Speech Discrimination: : Implications For The Sensorimotor ∆∞ Rhythm In Speech Processing, Andrew Lee Bowers

Theses and Dissertations (ETD)

Background: The functional significance of sensorimotor integration in acoustic speech processing is unclear despite more than three decades of neuroimaging research. Constructivist theories have long speculated that listeners make predictions about articulatory goals functioning to weight sensory analysis toward expected acoustic features (e.g. analysis-by-synthesis; internal models). Direct-realist accounts posit that sensorimotor integration is achieved via a direct match between incoming acoustic cues and articulatory gestures. A method capable of favoring one account over the other requires an ongoing, high-temporal resolution measure of sensorimotor cortical activity prior to and following acoustic input. Although scalp-recorded electroencephalography (EEG) provides a measure of cortical …

The Effect Of Concurrent Cognitive, Linguistic And Motor Tasks On Speech Intensity In Parkinson’S Disease, Teresa J. Valenzano

Electronic Thesis and Dissertation Repository

This study investigated the effect of concurrent tasks on speech intensity in Parkinson’s disease (PD). Thirteen PD participants and twenty-two controls performed three tasks concurrent with a speech task. The speech task involved a repeated carrier phrase and a target word. The concurrent tasks involved math addition (cognitive), verb generation (linguistic), and manual visuomotor tracking (motor) at three levels of difficulty. All three concurrent tasks were associated with reduced speech intensity relative to the isolated speech task. The concurrent motor task was generally associated with the greatest reduction in speech intensity. Task performance measures were not significantly different for the …

Speech Compensation To Formant Perturbations In English And Vietnamese Talkers, Linh L.T. Nguyen

Electronic Thesis and Dissertation Repository

The purpose of this experiment was to examine mechanisms underlying the auditory feedback system using Vietnamese and English talkers in response to feedback perturbations. F1 discrimination thresholds, vowel goodness ratings, and vowel category bounds for English /ɪ/ were determined. Vowel spaces were collected for both languages and auditory feedback of F1 was manipulated for English and Vietnamese vowels. Speech compensation during perturbed auditory feedback occurred in English and Vietnamese vowels suggesting that the underlying mechanisms are universal. However, there were differences in speech compensation for some vowel conditions, which may have occurred due to vowel location in each language group’s …

Effect Of Head Movement On Sound Localization In Real And Simulated Cochlear Implant Users, Kassandra-Anne H. Birtch

Electronic Thesis and Dissertation Repository

Cochlear implant (CI) users’ limited ability to use acoustical cues for sound localization causes left/right confusions and front/back reversals. Head movement is beneficial in reducing these errors in acoustically hearing listeners. This study investigated the effect of head movement on localization throughout 360o of azimuth for both real and simulated CI users. Listeners in a bilateral electro-acoustic (CI with ipsilateral hearing aid) simulation derived the greatest head movement benefit in reducing front/back reversals. Left/right confusions were reduced in simulations with matched bilateral stimulation. Sensitivity to both timing and level cues for sound localization was correlated with sound localization performance without …

Inspiratory Breathing Exercises For Vocal Tremor: A Preliminary Study, Jessica Tayseer Hilo

USF Tampa Graduate Theses and Dissertations

Essential voice tremor (EVT) is a voice disorder that results from dyscoordination within the laryngeal musculature, which negatively impacts the symmetrical motion of the vocal folds. Several investigators have shown that individuals with EVT experience difficulty speaking and a reduced quality of life (QOL; Cohen, Dupont, & Courey, 2006; Verdonck-de Leeuw & Mahieu, 2004). While traditional voice therapy has been ineffective in lessening the severity of vocal tremor, a current approach (Barkmeier- Kraemer, Lato, & Wiley, 2011) designed to lessen the perception of vocal tremor has resulted in reported patient satisfaction with little actual change in voice quality. The present …

The Effect Of Multitalker Background Noise On Speech Intelligibility In Parkinson's Disease And Controls, Talia M. Leszcz

Electronic Thesis and Dissertation Repository

This study investigated the effect of multi-talker background noise on speech intelligibility in participants with hypophonia due to Parkinson’s disease (PD). Ten individuals with PD and 10 geriatric controls were tested on four speech intelligibility tasks at the single word, sentence, and conversation level in various conditions of background noise. Listeners assessed speech intelligibility using word identification or orthographic transcription procedures. Results revealed non-significant differences between groups when intelligibility was assessed in no background noise. PD speech intelligibility decreased significantly relative to controls in the presence of background noise. A phonetic error analysis revealed a distinct error profile for PD …

Exploring Picture Word Priming Effects In Healthy Aging Adults Using Event Related Potentials, Sasha C. Christopher

USF Tampa Graduate Theses and Dissertations

Objective: The aim of the present study was to investigate the mechanics with which older adults activate and access different subdomains of their mental lexicons during word retrieval for picture naming.

Method: Data were analyzed for 12 aging, native English speakers who performed a picture-word priming task. The auditory probe words were presented in the following conditions in relation to the picture stimuli: Identically related, strongly semantically related, weakly semantically related, strongly phonologically related, weakly phonologically related, semantically related to the strong phonological relative of the target picture label, or phonologically-related to the strong semantic relative of the target picture …

Loudness Perception And Speech Intensity Control In Parkinson's Disease, Jenna Paula Clark

Electronic Thesis and Dissertation Repository

This study investigated the role of loudness perception and selected auditory processes in 17 participants with hypophonia related to Parkinson’s disease (PD) and 25 controls. For most of the five loudness perception tasks (magnitude estimation, imitation, speech-to-noise judgment, magnitude production, magnitude production in noise), the PD participants produced a significantly different pattern and used a more restricted range than the controls in their self-generated estimates of speech intensity and judgments of speech loudness. Results from two self-assessment questionnaires (CETI-M, M-SAPP) found that the PD participants perceived themselves as less effective communicators than controls. An audiometric evaluation suggested that the PD …

The Comprehension Of Metaphor By Preschool Children: Implications For A Theory Of Lexicon, Barbara Pearson

Barbara Zurer Pearson

Comprehension of metaphor in preschoolers was studied through an elicited repetition task. Subjects were 52 children ages 3;0 to 5;2. Repetition performance on metaphors was compared to repetitions of semantically well-formed literal sentences as well as semantically anomalous sentences, all matched for length, vocabulary and sentence structure. Accuracy on literal and metaphoric stimuli were comparable and both were significantly better than performance on anomalous sentences. There were no effects for age or sex. It was shown that the metaphors were not semantically anomalous to the children and that they were processed on a par with literal language. The argument is …

The Effect Of Early Cochlear Implantation On Oral Language: A Review Of The Literature, Nicole Supplee

Nicole Supplee

Current research suggests that implantation of cochlear implants before 2 years of age significantly impacts oral language development, specifically in increased rate of oral language development. In addition, children who have been implanted early (between 12 months and two years) have been shown to obtain age-appropriate language skills, whereas children who have been implanted later (after 2 years of age), or not implanted at all, do not. Because of the documented benefits of early implantation, researchers have recently pushed to lower the current minimum age of implantation to below 12 months of age. Although research suggests improvements in language development …

Relationships Between Vocabulary Size, Working Memory, And Phonological Awareness In Spanish-Speaking English Language Learners, Brenda K. Gorman

Speech Pathology and Audiology Faculty Research and Publications

Purpose: The goals of this study were to evaluate the impact of short-term phonological awareness (PA) instruction presented in children's first language (L1; Spanish) on gains in their L1 and second language (L2; English) and to determine whether relationships exist between vocabulary size, verbal working memory, and PA in Spanish-speaking English language learners (ELLs).

Method: Participants included 25 kindergartners who received PA instruction and 10 controls. A 2-way within-subjects repeated measures multivariate analysis of variance (MANOVA) was conducted to evaluate gains. Relationships between PA gains, Spanish and English vocabulary, and memory, as measured using nonword repetition and experimental …

Spatiotemporal Coupling Of The Tongue In Amyotrophic Lateral Sclerosis, Mili S. Kuruvilla, Jordan R. Green, Yana Yunusova, Kathy Hanford

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The primary aim of the investigation was to identify deficits in spatiotemporal coupling between tongue regions in amyotrophic lateral sclerosis (ALS). The relations between disease-related changes in tongue movement patterns and speech intelligibility were also determined.

Methods: The authors recorded word productions from 11 individuals with ALS with mild, moderate, and severe dysarthria using an x-ray microbeam during word productions. A coupling index based on sliding window covariance was used to determine disease-related changes in the coupling between the tongue regions across each word.

Results: The results indicated decreased spatiotemporal coupling of mid-posterior tongue regions and reduced tongue speed …

Impact Of Noise And Working Memory On Speech Processing In Adults With And Without Adhd, Anne M. P. Michalek

Communication Disorders & Special Education Theses & Dissertations

Auditory processing of speech is influenced by internal (i.e., attention, working memory) and external factors (i.e., background noise, visual information). This study examined the interplay among these factors in individuals with and without ADHD. All participants completed a listening in noise task, two working memory capacity tasks, and two short-term memory tasks. The listening in noise task had both an auditory and an audiovisual condition. Participants included 38 young adults between the ages of 18-35 without ADHD and 25 young adults between the ages of 18-35 with ADHD. Results indicated that diagnosis, modality, and signal-to-noise ratio all have a main …

Ototoxic Hearing Loss And Retinoblastoma Patients, Shaum Bhagat

Faculty Publications

Chemotherapy is often used in the conservative management of retinoblastoma. Chemotherapy drugs, while ameliorative, can produce long-lasting side effects that potentially can affect survivor quality of life. Carboplatin is a common chemotherapy agent with known ototoxic side effects that is used in the treatment of retinoblastoma (Rodriguez-Galindo et al., 2003). The potential for carboplatin-induced hearing loss is of concern to the medical professional, given that retinoblastoma is often diagnosed in early childhood and children with retinoblastoma have visual impairments. This chapter will outline the mechanisms underlying carboplatin ototoxicity. The extent of knowledge concerning the pathophysiology of carboplatin-induced hearing loss will …

Sentence Recognition From Articulatory Movements For Silent Speech Interfaces, Jun Wang, Ashok Samal, Jordan R. Green, Frank Rudzicz

Department of Special Education and Communication Disorders: Faculty Publications

Recent research has demonstrated the potential of using an articulation-based silent speech interface for command-and-control systems. Such an interface converts articulation to words that can then drive a text-to-speech synthesizer. In this paper, we have proposed a novel near-time algorithm to recognize whole-sentences from continuous tongue and lip movements. Our goal is to assist persons who are aphonic or have a severe motor speech impairment to produce functional speech using their tongue and lips. Our algorithm was tested using a functional sentence data set collected from ten speakers (3012 utterances). The average accuracy was 94.89% with an average latency of …

Effect Of Parallel Talk On The Language And Interactional Skills Of Preschoolers With Cochlear Implants And Hearing Aids, Sharon A. Raver, Jonna Bobzien, Corrin Richels, Peggy Hester, Anne Michalek, Nicole Anthony

Communication Disorders & Special Education Faculty Publications

Children with profound congenital hearing loss often do not have the same prelinguistic opportunities for social and verbal interaction as their peers with typical hearing [14]. Consequently, language and social skills may be challenging for this group, even after they are provided with amplification or a cochlear implant. This pilot study examined the effectiveness of using a parallel talk intervention to increase the language and interactional skills of three preschoolers with deafnesss. Results revealed that all participants increased verbal turn-taking and that two of the three increased initiated and responded vocal/verbal comments, and initiated and responded nonverbal responses during a …

ETSU Faculty Works

Background. This study reports comparative phonological assessment results for children with cleft lip and/or palate (CLP) to typically developing peers using an evaluation tool for early phonological skills. Methods. Children without clefts (NC = noncleft) and 24 children with CLP, ages of 18–36 months, were evaluated using the Profile of Early Expressive Phonological Skills (PEEPSs) [1]. Children interacted with toy manipulatives to elicit a representative sample of target English consonants and syllable structures that are typically acquired by children between 18 and 27 months of age. Results. Results revealed significant differences between the two groups with regard to measures of …

Sensitivity To Probabilistic Orthographic Cues To Lexical Stress In Adolescent Speakers With Autism Spectrum Disorder And Typical Peers, Joanne Arciuli, Rhea Paul

Communication Disorders Faculty Publications

Lexical stress refers to the opposition of strong and weak syllables within polysyllabic words and is a core feature of the English prosodic system. There are probabilistic cues to lexical stress present in English orthography. For example, most disyllabic English words ending with the letters “-ure” have first-syllable stress (e.g., “pasture”, but note words such as “endure”), whereas most ending with “-ose” have second-syllable stress (e.g., “propose”, but note examples such as “glucose”). Adult native speakers of English are sensitive to these probabilities during silent reading. During testing, they tend to assign first-syllable stress when reading a nonword such as …
