The Hypothesis Of Apraxia Of Speech In Children With Autism Spectrum Disorder, Lawrence D. Shriberg, Rhea Paul, Lois M. Black, Jan P. Van Santen

Communication Disorders Faculty Publications

In a sample of 46 children aged 4-7 years with Autism Spectrum Disorder (ASD) and intelligible speech, there was no statistical support for the hypothesis of concomitant Childhood Apraxia of Speech (CAS). Perceptual and acoustic measures of participants' speech, prosody, and voice were compared with data from 40 typically-developing children, 13 preschool children with Speech Delay, and 15 participants aged 5-49 years with CAS in neurogenetic disorders. Speech Delay and Speech Errors, respectively, were modestly and substantially more prevalent in participants with ASD than reported population estimates. Double dissociations in speech, prosody, and voice impairments in ASD were interpreted as …

Articulation Rate And Its Relationship To Disfluency Type, Duration, And Temperament In Preschool Children Who Stutter, Victoria Tumanova, Patricia M. Zebrowski, Rebecca Throneburg, Mavis E. Kulak Kayikci

Faculty Research and Creative Activity

The purpose of this study was to examine the relationship between articulation rate, frequency and duration of disfluencies of different types, and temperament in preschool children who stutter (CWS). In spontaneous speech samples from 19 children CWS (mean age = 3:9; years: months), we measured articulation rate, the frequency and duration of (a) sound prolongations; (b) soundsyllable repetitions; (c) single syllable whole word repetitions; and (d) clusters. Temperament was assessed with the Children’s Behavior Questionnaire (Rothbart et al., 2001). There was a significant negative correlation between articulation rate and average duration of sound prolongations (p<0.01), and between articulation rate and frequency of stuttering-like disfluencies (SLDs) (p<0.05). No other relationships proved statistically significant. Results do not support models of stuttering development that implicate particular characteristics of temperament as proximal contributors to stuttering; however, this is likely due to the fact that current methods, including the ones used in the present study, do not allow for the identification of a functional relationship between temperament and speech production. Findings do indicate that for some CWS, relatively longer sound prolongations co-occur with relatively slower speech rate, which suggests that sound prolongations, across a range of durations, may represent a distinct type of SLD, not just in their obvious perceptual characteristics, but in their potential influence on overall speech production at multiple levels.

Listener Reliability And Agreement Of A Brief Intelligibility Rating Task, Cai Ewing-Buck

Speech and Hearing Sciences ETDs

PURPOSE: This study addresses the development of the I-RAVN Test of Speech Intelligibility, an assessment instrument designed to identify which speech components most affect speech intelligibility. The I-RAVN consists of ratings of overall intelligibility, and ratings of four speech components: rate/rhythm/prosody, articulation, voice quality/breath support, and nasality using a rating scale technique adapted from the CAPE-V instrument for voice. This study seeks to establish that listeners can reliably rate overall intelligibility and the four speech components in speakers with dysarthria. METHODS: Twenty-two graduate students listened to recordings from 24 talkers (7 normal, 6 with Parkinson Disease, 11 with oculopharyngeal muscular …

Talk To Me: Issues In Acquiring Spoken Language For Young Children With Autism Spectrum Disorders, Rhea Paul

Communication Disorders Faculty Publications

Speech-language pathologists play a critical role in the treatment of children with autism spectrum disorders (ASD) because communication deficits are a primary component of both the diagnostic criteria and the focus of educational services for children with these conditions. Children with ASD almost always are delayed in speech acquisition (Tager-Flusberg, Paul, & Lord, 2005), as well as in other areas of communication. Lack of speech is often the most obvious symptom and greatest cause for concern of parents of toddlers who are eventually diagnosed with ASD, even though closer observation usually reveals additional problems.

The Effects Of Intensive Lower Limb Training On The Speech Of Patients With Parkinson's Disease, Lauren Fjeldsted Allen

Theses and Dissertations

Research has documented the positive effects of physical therapy as a treatment for limb motor symptoms associated with Parkinson's disease (PD). Previous studies have shown that speech and voice measures can be reflective of overall cardiovascular health and fitness in young, middle-aged, and older adults. In healthy individuals, increased respiratory drive has been found to influence vocal function and speech articulation. The rationale for the present study was that improved lower limb function might lead to improvements in overall fitness, which then may influence speech in individuals with Parkinson's disease. To investigate this premise, 10 participants diagnosed with mild to …

The Effects Of Task Preference On Speech And Motor Performance Under Divided Attention Conditions, Amy Sue Leiter

Theses and Dissertations

Dual task performance and the interaction of tasks has been the subject of much research. When tasks are performed together they affect each other to varying degrees depending upon such factors as the similarity of the tasks, their difficulty, and whether one task is given preference over another. In this study, task preference was investigated under divided attention conditions in order to determine what effect preference had on task performance. Twenty young adults took part in this study and were randomly assigned into two groups. Each group was experimentally motivated to favor one of the two tasks – either speaking …

Effects Of Delayed Auditory Feedback On The Bereitschaftspotential, Jennifer L. Johnson

Theses and Dissertations

This study examined the brain electrical activity of normal speakers in a non-delayed auditory feedback (DAF) condition and when experiencing DAF to determine the effect DAF would have on the Bereitschaftspotential (BP). The BP reflects the preparatory state of a person prior to motor execution of an act and can be observed 1500 to 500 ms prior to voluntary movement. The participants in the study included 10 adults with normal speech. Each read a series of 30 sentences, both without DAF and with DAF, while the BP was measured. Results indicate that the BP is present across the scalp in …

Acoustic And Spectral Characteristics Of Young Children's Fricative Productions: A Developmental Perspective, Shawn L. Nissen, Robert Allen Fox

Faculty Publications

Scientists have made great strides toward understanding the mechanisms of speech production and perception. However, the complex relationships between the acoustic structures of speech and the resulting psychological percepts have yet to be fully and adequately explained, especially in speech produced by younger children. Thus, this study examined the acoustic structure of voiceless fricatives (/f, θ, s, ʃ/) produced by adults and typically developing children from 3 to 6 years of age in terms of multiple acoustic parameters (durations, normalized amplitude, spectral slope, and spectral moments). It was found the acoustic parameters of spectral slope and variance (commonly excluded from …

How Individuals With Parkinson's Disease Modify Their Speech In A Repetition For Clarification, Lynn Marie Watkins

Theses and Dissertations

The speech of individuals with Parkinson's disease (PD) is typically characterized as lacking in proper prosody because of its monopitch and monoloud quality, in addition to its reduced intensity. These qualities make it difficult for others to understand speakers with PD. The purpose of the current study was to identify what individuals with PD would do vocally, if anything at all, to improve speech production following a simulated misunderstanding of what they had just said. The study evaluated the performance of 5 individuals with PD and compared their performance to 5 age- and sex-matched controls. Specifically, measures of vocal intensity …

Exploration Of Lip Shape Measures And Their Association With Tongue Contact Patterns, Jessica Lynn Wagner

Theses and Dissertations

A variety of tools and techniques have been developed to measure the movements of the vocal tract, specifically of the tongue and lips. In recent years, computer technology has allowed for extensive exploration of these precise movements and for the development of speech recognition systems. However, there has been relatively little work on the combination of visible facial movements and internal articulatory activity. In this study, two different technologies were used to explore the internal and external movements of speech production in eight speakers: palatometry quantified tongue contact patterns and computerized video image analysis was used to derive lip shape …

An Investigation Of Vocal Abuse In School Teachers, Jodi L. Franczak

Theses and Dissertations

The purpose of this study was to examine the effects of vocal abuse in school teachers and teacher's aides pre and post one academic term. Vocal abuse was defined as any of several behaviors, including long periods of talking, yelling, smoking, consuming alcohol, etc. that can result in damage to the laryngeal mechanism. Initially, the participants of the study included fifteen elementary school teachers and five elementary teacher's aides from two schools: the Red Lake Madsen Public School, and Golden Learning Center. Six participants were excluded from the study for various reasons. Participants were randomly assigned to either Group 1 …

An Investigation Of The Effects Of Subthalamic Nucleus Stimulation On Acoustic Measures Of Voice, Christopher Dromey, Rajeev Kumar, Anthony E. Lang, Andres M. Lozano

Faculty Publications

Summary: Seven patients with Parkinson’s disease were implanted with deep brain stimulators to provide chronic electrical stimulation to the subthalamic nucleus bilaterally. Acoustic recordings and neurologic assessments were undertaken before surgery in the medication-off and medication-on conditions and after surgery with and without electrical stimulation in the medication off and medication-on conditions. The data showed significant improvements in limb motor performance in response to medication before surgery and when the subthalamic nucleus was stimulated after surgery. Six months after surgery, there were small but statistically significant increases in sound pressure level and fundamental frequency variability in response to stimulation in …

Gross Estimation: A Study Of The Clinical Validity For Measuring Intelligibility, Heather Gail Clarke

Dissertations and Theses

Intelligibility is the most fundamental factor for successful speech communication. Measurements of speech intelligibility carry important clinical consequences that relate to description of severity, need for intervention, intervention goals, service delivery options, and treatment efficacy. It is important, therefore, that speech-language pathologists use an approach that reflects an accurate and valid measure of intelligibility. The purpose of this study was to investigate the relationship between the two seemingly most common procedures used by practicing speech-language pathologists for measuring speech intelligibility: the gross estimation of intelligibility procedure, and the orthographic transcription procedure. Twelve 100-word connected speech samples were analyzed by 4 …

Validation Of The Rapid Speech Transmission Index (Rasti) In A Classroom Environment, Jeffery Larsen

Undergraduate Honors Capstone Projects

Because the acoustics of a room have a substantial impact on speech intelligibility, researchers have tried over the years to develop the most effective way to evaluate the effects of the acoustic environment on speech intelligibility. Both subjective and objective measures of speech intelligibility have been devised. For the purposes of this study, subjective measures are those in which a speech recognition test is given to a group of subjects whose scores provide a direct indication of speech intelligibility at each position in the listening environment {Steeneken & Houtgast, 1980). Objective measures are those that determine the acoustic factors that …

The Intelligibility Of Japanese Speakers Of English To Native Speakers Of English, Manabu Aoki

All Master's Theses

This research was conducted to identify the most important English speech sounds which determine non-native English speakers' intelligibility to native speakers of English. The researcher focused on variation of pronunciation by Japanese English speakers of differing levels of proficiency and examined the correlation between their pronunciation and intelligibility to native speakers. The results provided some keys to intelligible English speech and some implications for developing comprehensible speech in teaching English as a second language or English as a foreign language.

A Phonics And Whole Language Synthesis, Anne I. Allsworth

All Graduate Projects

The debate among phonics instruction and the whole language approach and the research supporting a balanced approach were examined. High utility phonics generalizations were identified from the literature. Those high utility phonics generalizations that were appropriate for the primary grades were applied to the vocabulary of a set of whole language readers. Lessons and activities were developed to integrate phonics instruction with the whole language materials for first grade students. Implications for further research and teacher training were discussed.

Verbal Fluency Performance Of Normal Elderly Subjects, Molly Secrest

Dissertations and Theses

The purpose of this study was to measure the verbal fluency of normal gerontologic subjects and to determine the extent of association between verbal fluency score and level of education. Specifically, this investigation sought to determine means, ranges and standard deviations for three groups of subjects: those 61 to 69 years of age, those 70 to 79 years of age, and those 80 years of age and above. In addition, correlations between verbal fluency score, and age, sex, years of education, and order of stimulus presentation were computed.

Listening Rate Preferences Of Language Disordered Children As A Function Of Grammatical Complexity, Wendy Lee Orloff

Dissertations and Theses

The purpose of this investigation was to determine if performance on a language comprehension task, varying in number of syntactical units (i.e., grammatical complexity) was affected by altered rates of speech. A total of twenty-four language disordered children, aged 7 years, 8 months, through 9 years, 8 months, who were enrolled in language/learning disorders classrooms in the Portland Public Schools served as subjects. The Assessment of Children's Language Comprehension (Foster et al., 1972) test was administered to each subject via audio-tape at one expanded (100 wpm), one normal (150 wpm), and two compressed rates (200, 250 wpm) of speech.

A Study Of The Changes Of Personality, Attitudes, And Speech Problems Of An Adult Stutterer While Undergoing Speech Therapy, Halvor P. Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are more than one million stutterers in the United States today, no less than 350,000 of whom are public school children (21). Rogers (22) estimated that the number of stuttering children in the United States is five times as many as the combined numbers of blind and deaf children. The incidence of stuttering is around one percent of the population (2,6,20). Around 20,000 stutterers are added to the number annually each year (13). Stutterers have been helped by many different methods of treatment based on many conflicting theories and therapies.
