A Computer-Based Articulation Training Aid For Short Words (Cata), Mukund Devarajan

Electrical & Computer Engineering Theses & Dissertations

Several improvements in the vowel articulation training aid (VATA) are described, as well as the efforts to extend the visual feedback system to operate with short words in the form of consonant, vowel and consonant (CVC). The extended version of the visual feedback system is referred to as CATA (Computer-based Articulation Training Aid); the vowel version of the aid (VATA) only operates with ten American English monopthong vowels. Improvements in VATA include the use of a neural network (NN) recognizer method to prune a large database of vowel recordings to eliminate noisy and/or mispronounced tokens. The spectral jitter problem, previously …

Phonological Awareness In Spanish: A Tutorial For Speech-Language Pathologists, Brenda K. Gorman, Ronald B. Gillam

Speech Pathology and Audiology Faculty Research and Publications

In the United States, more than 2 million children in Grades pre-K through 6 speak Spanish as their primary language. Approximately 50% of these students receive academic instruction in Spanish. This tutorial provides research-based recommendations for presenting phonological awareness tasks to children who receive literacy instruction in Spanish. The authors also discuss how phonological awareness development may differ between monolingual children learning Spanish and monolingual children learning English, and the implications of these differences for choosing appropriate phonological awareness tasks for Spanish speakers.

The Validity And Reliability Of The Motion Sensitivity Test, Faith W. Akin, Mary Jo Davenport

ETSU Faculty Works

The Motion Sensitivity Test (MST) is a clinical protocol designed to measure motion-provoked dizziness during a series of 16 quick changes to head or body positions. The MST has been used as a guide for developing an exercise program for patients with motion-provoked dizziness and as a treatment outcome measure to monitor the effectiveness of vestibular rehabilitation therapy. This study determined validity, test-retest reliability, and interrater reliability of the MST. Fifteen individuals with motion-provoked dizziness and ten control individuals were tested during sessions occurring 90 min and/or 24 hr after baseline testing. The MST was found to be reliable across …

Vocal Dose Measures: Quantifying Accumulated Vibration Exposure In Vocal Fold Tissues, Ingo R. Titze, Jan G. Švec, Peter Popolo

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

To measure the exposure to self-induced tissue vibration in speech, three vocal doses were defined and described: distance dose, which accumulates the distance that tissue particles of the vocal folds travel in an oscillatory trajectory; energy dissipation dose, which accumulates the total amount of heat dissipated over a unit volume of vocal fold tissues; and time dose, which accumulates the total phonation time. These doses were compared to a previously used vocal dose measure, the vocal loading index, which accumulates the number of vibration cycles of the vocal folds. Empirical rules for viscosity and vocal fold deformation were used to …

Representation Of Lexical Form, Conor T. Mclennan, Paul A. Luce, Jan Charles_Luce

Psychology Faculty Publications

The authors attempted to determine whether surface representations of spoken words are mapped onto underlying, abstract representations. In particular, they tested the hypothesis that flaps—neutralized allophones of intervocalic /t/s and /d/s—are mapped onto their underlying phonemic counterparts. In 6 repetition priming experiments, participants responded to stimuli in 2 blocks of trials. Stimuli in the 1st block served as primes and those in the 2nd as targets. Primes and targets consisted of English words containing intervocalic /t/s and /d/s that, when produced casually, were flapped. In all 6 experiments, reaction times to target items were measured as a function of prime …

Automatic Speaker Identification Using Reusable And Retrainable Binary-Pair Partitioned Neural Networks, Ashutosh Mishra

Electrical & Computer Engineering Theses & Dissertations

This thesis presents an extension of the work previously done on speaker identification using Binary Pair Partitioned (BPP) neural networks. In the previous work, a separate network was used for each pair of speakers in the speaker population. Although the basic BPP approach did perform well and had a simple underlying algorithm, it had the obvious disadvantage of requiring an extremely large number of networks for speaker identification with large speaker populations. It also requires training of networks proportional to the square of the number of speakers under consideration, leading to a very large number of networks to be trained …

Right Hemisphere Effects On Language Processing: Suppression Or Activation Deficit, Sarah A. Orjada

Masters Theses

This study was designed to add to the body of research that examines the possibility of semantic activation or suppression deficits as underlying right hemisphere communication disorders. Modified treatment techniques for activation and suppression deficits proposed by Myers (1999) were used as stimuli for the experimental tasks. A total of four RHD participants and four control participants matched in age, gender, and level of education were included in the study. The study aimed to answer the following questions. Do RHD or control participants have higher scores on the suppression tasks? Do RHD participants have longer reaction times? Do RHD or …

The Immediate Effects Of Vestibular Stimulation On The Language Performance Of A Child With Autism, Jennifer L. Sova

Masters Theses

There is a proposed link between sensory processing abilities and language performance in children with autism. Research evaluating such a relationship is limited. This study sought to evaluate the hypothesis that language expression is facilitated by the application of vestibular stimulation in a child with autism. The purpose of the present study was to implement language interaction techniques and measure the outcome of language performance in a 4-year-old child with autism and sensory integration dysfunction. The child was evaluated in regards to vestibular stimulation and its facilitative effect on language production for social communicative purposes. Direct observation was used to …

Masters Theses

This study was designed to evaluate the Pediatric Test of Brain Injury (PTBI), as well as to examine information obtained from informal measures in assessing children and adolescents with traumatic brain injury (TBI). Three students with TBI and three grade- and gender- matched subjects participated in this study. All six students were administered the PTBI, and their performances were given raw scores, rated for level of difficulty in performing the tasks, and compared among and across the two groups. The students with TBI were interviewed by the graduate student researcher regarding self-perceptions of their strengths and weaknesses. In addition, their …

Individual Phonological Awareness Training For Speech/Language Impaired First Graders, Sarah Weaver

Masters Theses

The purpose of the present study is to determine the effects of individual phonological awareness and phonics training emphasizing auditory, motoric, and alphabetic properties of phonemes with 3 children who did not make substantial gains following classroom phonological awareness intervention. Subjects were enrolled in the first grade and exhibited speech and/or language impairments. The individual phonological awareness program contained 3 parts: (1) phonological awareness, (2) phoneme-grapheme correspondence, and (3) decoding and spelling and employed a single subject multiple probe baseline across behaviors design. Results indicated that individual treatment was successful for teaching phonological awareness, phoneme-grapheme correspondence, and decoding and spelling. …

Subjects were identified through a local university speech and …

Self-Perceptions Of Speech Language Pathologists-In-Training Before And After Pseudostuttering Experiences On The Telephone, Manish Rami, Joseph Kalinowski, Andrew Stuart, Michael P. Rastatter

Communication Sciences & Disorders Faculty Publications

Purpose: This survey investigated the effect of pseudostuttering experiences on self-perceptions of 29 female, graduate students enrolled in a graduate seminar in stuttering.

Method: Perceptions of self prior to, and immediately after, participation in five scripted telephone calls which contained pseudostuttering were measured via a 25-item semantic differential scale.

Results: Data showed that the participants perceived themselves as significantly more (p < 0.002) withdrawn, tense, avoiding, afraid, introverted, nervous, self-conscious, anxious, quiet, inflexible, hesitant, dull, passive, unpleasant, insecure, unfriendly, guarded, and reticent. after their pseudostuttering telephone call experiences.

Conclusions: Findings suggests that the ‘pseudostuttering’ experiences have an impact on self-perceptions and that the experience of ‘adopting the disability of a person who stutter’s’ may provide insight as to the social and emotional impact of communicative failure. …

Automated Grammatical Tagging Of Language Samples From Children With And Without Language Impairment, Deborah Millet

Theses and Dissertations

Grammatical classification ("tagging") of words in language samples is a component of syntactic analysis for both clinical and research purposes. Previous studies have shown that probability-based software can be used to tag samples from adults and typically-developing children with high (about 95%) accuracy. The present study found that similar accuracy can be obtained in tagging samples from school-aged children with and without language impairment if the software uses tri-gram rather than bi-gram probabilities and large corpora are used to obtain probability information to train the tagging software.

A Vision System Performing Lip Shape Analysis For Speech Pathology Research, Christopher Dromey, D J. Lee, Daniel Bates, Xiaoqian Xu

Faculty Publications

We have built a machine vision system to perform lip shape analysis and recognition and to generate 3.D lip models for speech pathology research. The system employs two color cameras that are synchronized to capture image video pairs simultaneously. A novel color segmentation technique that converts the RGB color components to linear color space has been developed to extract lip shape contours. Lip shape of the viseme, the smallest visibly distinguishable unit of speech, is used to identify its corresponding image frame in the recorded image sequences. It is also used to reconstruct the 3-D lip shape model as a …

An Imaging System Correlating Lip Shapes With Tongue Contact Patterns For Speech Pathology Research, Christopher Dromey, Daniel Bates, Xiaoqian Xu, Sameer Antani, D J. Lee

Faculty Publications

In this research, an imaging system was built to work with a newly developed electronic device to help people produce sounds correctly. The system consists of two parts, the internal tongue contact pattern data collection and the external lip shape information analysis. The tongue position information was gathered using the palatometer, an innovative tongue contact pattern-tracking device invented by Dr. Samuel Fletcher. The lip shape information was collected by processing images taken from people articulating different sounds. We developed an efficient color image segmentation technique to extract lip contour points and form a closed curve for shape analysis. The geometry …

Treatment Of Adynamia In Aphasia, Anastasia M. Raymer

Communication Disorders & Special Education Faculty Publications

Transcortical motor aphasia (TCMA) is an acquired impairment of language expression that occurs following neurologic damage that affects left frontal cortex and spares perisylvian regions. In some individuals with TCMA, verbal expression is rendered nonfluent due to difficulty spontaneously initiating and elaborating upon verbal messages. Nonfluency arises from impaired activation of intended messages and inhibition of competing verbal expressions. This impairment of the intentional aspects of language expression can be termed 'adynamia.' Because adynamic forms of TCMA occur infrequently, few systematic treatment investigations have been reported for this condition. Behavioral treatments have been proposed to engage intact frontal regions to …

Spectral Measures And Perceptual Ratings Of Hypokinetic Dysarthria, Christopher Dromey

Faculty Publications

Ten individuals with Parkinson disease (PD) and hypokinetic dysarthria were compared with age-matched neurologically normal (NN) speakers on acoustic measures from speaking and vowel phonation tasks as well as on perceptual ratings of connected speech. Listeners identified differences between the groups when asked to judge the severity of vocal and articulatory impairment during reading. Several conventional acoustic measures failed to differentiate speakers with PD from NN speakers. However, measures of the shape (statistical moments) of the long term average spectrum (LTAS) revealed statistically significant differences between the groups across vowel phonation, reading and monologue tasks. The ease of computation of …

The Effect Of High Frequency Amplification On Subjective And Objective Benefit With Digital Hearing Instruments, Erica Lynn Fleck

LSU Master's Theses

The purpose of the present study was to determine whether amplifying beyond 3 kHz was beneficial to the user, whether the benefit was dependent on degree of loss, and whether subjective data reflected the benefit. Seventeen hearing impaired subjects were binaurally fitted with digital hearing instruments. Qualified subjects were divided into two groups, A and B. Group A had a pure tone average (3,4, and 6 kHz), of 55 dBHL or better. Group B had a pure tone average (3,4, and 6 kHz) greater than 55 dBHL but not exceeding 75 dBHL. Each subject was fit with two conditions (upward …

A Comparative Study Of Two Treatment Approaches For Improving Middle School Students' Reading Comprehension, Vessa Annette Cartmill

LSU Master's Theses

Participants were two 5th grade students and three 6th grade students, classified as learning disabled according to criteria of the State of Louisiana. Students took part in the study 3 times per week, 40 minutes per day for 5 ½ weeks during their regular speech-language therapy time. After each …

The Effects Of Expansion On Objective And Subjective Benefit In Hearing-Impaired Listeners, Ashley B. Hill

LSU Master's Theses

The present research involves two studies. Twenty hearing-impaired participants were divided into two groups depending on their audiometric data and binaurally fit with the Starkey Endeavour 3211 hearing instruments. Experiment I was designed to determine if the use of expansion technology affected objective and subjective benefit in hearing-impaired listeners. Probe microphone measures were obtained at 40, 50, and 60 dB SPL and with the speaker deactivated to ensure that the expansion feature was functioning. Listener performance was measured in quite using the Connected Speech Test (CST) and in noise using the Hearing in Noise Test (HINT) at 40, 50, and …

Alternative Language Sample Analyses For The Assessment Of Low-Income African American Children, Christy Gayle Wynn

LSU Master's Theses

The purpose of this study was to examine the clinical utility of three language sample analyses when working with low-income, African American (AA) children. Eighteen normally developing and three at-risk AA three-year-old preschoolers participated in the study. Language samples were elicited from each child during a 15-20 minute play interaction. Three language sample analyses, contrastive analysis, average sentence length, and complex syntax use, were completed on each language sample. Also coded was each child’s use of nonmainstream African American English (AAE) patterns. Only the contrastive analysis generated reliable differences between the at-risk children and the normally developing children. Other group …

Effects Of Concurrent Motor, Linguistic, Or Cognitive Tasks On Speech Motor Performance, Christopher Dromey, April Benson

Faculty Publications

This study examined the influence of 3 different types of concurrent tasks on speech motor performance. The goal was to uncover potential differences in speech movements relating to the nature of the secondary task. Twenty young adults repeated sentences either with or without simultaneous distractor activities. These distractions included a motor task (putting together washers, nuts, and bolts), a linguistic task (generating verbs from nouns), and a cognitive task(performing mental arithmetic). Lip movement data collected during the experimental conditions revealed decreases in displacement and velocity during the motor task. The linguistic and cognitive tasks were associated with increased spatiotemporal variability …
