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 …

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 …

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 Efficacy Of Melodic Based Communication Therapy For Eliciting Speech In Nonverbal Children With Autism, Givona A. Sandiford

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this dissertation is to compare the efficacy of Melodic Based Communication Therapy (MBCT) to traditional speech and language therapy for eliciting speech in nonverbal children with autism.

Additionally it examines the effect of exposure to MBCT on social language abilities as measured by score on the Pragmatic Language Skills Inventory (PLSI); the effect of age on the response to treatment, and the predictors of overall effectiveness of treatment. Participants were 12 nonverbal children with autism ages 5 through 7 randomly assigned …

Intelligibility And The Sinewave Speech Carrier Phrase Effect, Danielle R. Werle

Honors Theses

Several studies have examined the perception of sinewave speech. Early work showed that listeners could transcribe sinewave sentences. Recent work on sinewave vowels found that listeners could recognize sinewave speech at the phonetic level with moderate (about 50-55%) accuracy. Sinewave vowel intelligibility scores improve significantly when preceded by a sinewave carrier phrase, an effect that disappears when the carrier phrase is removed. The present study was designed to examine this carrier phrase enhancement effect and analyze whether listeners require the carrier phrase to be intelligible to produce increased intelligibility scores. Sinusoidal carrier phrases and /hVd/ syllables were generated from recordings …

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 …

Spontaneous Recovery In Children With Expressive Language Delay, Jaimie Sierakowski

Honors Theses

By age 2, most children have an expressive vocabulary of approximately 200 words and begin to combine these words into meaningful phrases. However, some children acquire expressive language skills more slowly than others while displaying no signs of cognitive, receptive, or sensory delays. These children who experience an expressive language delay are often characterized in the literature as late talkers. Research shows that many of these children have delays early in childhood, but eventually catch up to their typically-developing peers, with no need for language intervention. Others, however, continue to experience expressive delays and. have an increased risk of developing …

Nonword Repetition And Interactions Among Vocabulary, Phonotactic Probability, And Phonological Awareness In Four Linguistic Groups, Sue Ann S. Lee, Brenda K. Gorman

Speech Pathology and Audiology Faculty Research and Publications

The current study was designed to compare the English nonword repetition accuracy in 7-year-old monolingual English, Korean–English bilingual, Chinese–English bilingual, and Spanish–English bilingual children. The relationships among nonword repetition accuracy, vocabulary, phonological awareness, and phonotactic probability in each group of children were also examined. The results indicated significant differences among the groups’ accuracy of consonants and vowels by syllable length. Different correlational patterns emerged among nonword repetition accuracy, vocabulary, and phonological awareness. Theoretical and clinical implications for the use of nonword repetition tasks for children from various linguistic backgrounds are discussed.

Let's Talk Speech! Volume 5 Issue 1, Barbara T. Schmidt Ph.D.

Communication Sciences and Disorders Newsletter

The 2011-2012 academic year has been wonderful and full of exciting changes. You are probably all getting tired of hearing me say that each semester! I cannot avoid saying it. We have new full time and part time faculty, great students, plans for an upcoming “relaxation retreat,” an annual scholarship fundraiser, a 2013 trip to Ireland, and so much more. However, as I reflect on the year and the articles that were submitted to the Newsletter, I feel compelled to point out that the SpeechLanguage Pathology Department is facing one major problem: we have too many exceptional students and faculty …

The Effects Of Background Noise On Distortion Product Otoacoustic Emissions And Hearing Screenings, Amy E. Hollowell

Doctoral Dissertations

Hearing screenings are an important tool for identifying children who have, or are at risk for hearing loss in the schools. In light of a body of evidence that demonstrates the effectiveness of objective screening measures, such as otoacoustic emissions (OAEs), the American Speech Language and Hearing Association (ASHA) recommends traditional pure tone audiometric screening as the tool of choice for hearing screenings in the schools. Pure tone audiometric screenings conducted in the schools are problematic for a number of reasons, but the most significant is the presence of background noise which is routinely encountered. The main purpose of the …

Development Of An Elementary School Background Noise, Amanda L. Mccann

Doctoral Dissertations

The deleterious effects of noise on hearing, comprehension, and academic development have been widely studied. In an effort to accurately observe the effects of noise on specific listening environments, researchers have relied on commercially available forms of background noise. However, these commercially available recordings only contain adult speech and background noises associated with adult environments. A commercially available form of background noise that represents the sounds associated with elementary and middle schools are not readily available. Given that much effort has gone into examining the effects of background noise on classroom performance, it would appear prudent that a background noise …

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

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 …

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 …

The Pacific Assessment Of Confabulation, Larry Boles

School of Pharmacy Faculty Presentations

This paper presents data on the Pacific Assessment of Confabulation (PAC), which was designed to accomplish two goals. First, the PAC is intended to quantify confabulation. Confabulation has been described as dichotomous (i.e., present or absent), without attempts to quantify it. A second goal is to test the hypothesis that occurs in the normal population. Literature related to witness testimony suggests this may be true.

Self-Modeling As An Intervention For Stuttering In Elementary Students, Jason Northrup

Legacy Theses & Dissertations (2009 - 2024)

Stuttering is a disorder involving disruptions and disfluencies in speech that impacts overall communication and affects approximately 1% of the population. In addition to speech disfluency, stuttering is often related to physical tension, embarrassment, fear, anxiety, and other negative social-emotional problems, especially for children and adolescents. Fortunately, research indicates that stuttering can be alleviated before becoming more advanced and complex as individuals enter adolescence and adulthood. Self-modeling, an intervention that involves individuals watching themselves engage in exemplary behavior, appears to be particularly effective for individuals who stutter and can be implemented in a school setting. The purpose of this study …

Rural Speech-Language Pathologists' Perceptions And Knowledge Of Emergent Literacy Instructional Practices: A Mixed Methods Study, Kellie C. Ellis

Theses and Dissertations--Rehabilitation Sciences

The acquisition of emergent literacy skills has become a prominent focus of early childhood education programs in recent years as research has demonstrated the significance of emergent literacy ability in the process of learning to read. The effectiveness of use of varied instructional techniques targeting the emergent literacy domains of phonological awareness, written language awareness, emergent writing, and oral language is well described in the literature. Consequently, educational service providers like speech-language pathologists are being called upon to assume roles in emergent literacy service provision. However, research has not fully explored the perceptions and knowledge speech-language pathologists possess of emergent …
