Monaural Speech-In-Noise Thresholds Using The Hearing In Noise Test (Hint), Denise Parrish

USF Tampa Graduate Theses and Dissertations

Understanding speech in background noise is occasionally difficult for normal hearing listeners and is often impossible for the listener with sensorineural hearing loss. The ability to understand speech in noise depends upon multiple factors such as the characteristics of the speech signal, the signal-to-noise ratio, and the listener's degree of hearing impairment. A routine hearing evaluation usually does not provide ample information about a listener's functional communication abilities. The Hearing-in-Noise Test (HINT) developed by The House Ear Institute provides an efficient and reliable method for evaluating an individual's suprathreshold speech understanding ability in quiet and in noise.

Effect Sizes, Significance Tests, And Confidence Intervals: Assessing The Influence And Impact Of Research Reporting Protocol And Practice, Melinda Rae Hess

USF Tampa Graduate Theses and Dissertations

This study addresses research reporting practices and protocols by bridging the gap from the theoretical and conceptual debates typically found in the literature with more realistic applications using data from published research. Specifically, the practice of using findings of statistical analysis as the primary, and often only, basis for results and conclusions of research is investigated through computing effect size and confidence intervals and considering how their use might impact the strength of inferences and conclusions reported.

Using a sample of published manuscripts from three peer-rviewed journals, central quantitative findings were expressed as dichotomous hypothesis test results, point estimates of …

Fpga-Based Implementation Of Concatenative Speech Synthesis Algorithm, Praveen Kumar Bamini

USF Tampa Graduate Theses and Dissertations

The main aim of a text-to-speech synthesis system is to convert ordinary text into an acoustic signal that is indistinguishable from human speech. This thesis presents an architecture to implement a concatenative speech synthesis algorithm targeted to FPGAs. Many current text-to-speech systems are based on the concatenation of acoustic units of recorded speech. Current concatenative speech synthesizers are capable of producing highly intelligible speech. However, the quality of speech often suffers from discontinuities between the acoustic units, due to contextual differences. This is the easiest method to produce synthetic speech. It concatenates prerecorded acoustic elements and forms a continuous speech …

Representation And Interpretation Of Manual And Non-Manual Information For Automated American Sign Language Recognition, Ayush S. Parashar

USF Tampa Graduate Theses and Dissertations

Continuous recognition of sign language has many practical applications and it can help to improve the quality of life of deaf persons by facilitating their interaction with hearing populace in public situations. This has led to some research in automated continuous American Sign Language recognition. But most work in continuous ASL recognition has only used top-down Hidden Markov Model (HMM) based approaches for recognition. There is no work on using facial information, which is considered to be fairly important. In this thesis, we explore bottom-up approach based on the use of Relational Distributions and Space of Probability Functions (SoPF) for …

Computer Mediated Peer Response And Its Impact On Revision In The College Spanish Classroom: A Case Study, Ruth Roux-Rodriguez

USF Tampa Graduate Theses and Dissertations

Peer response in which students work together in dyads or small groups to critique and provide feedback on one another's writing is compatible with communicative approaches to foreign language teaching and process approaches to the teaching of writing. Computer-mediated communication has been considered a viable tool for both the teaching of languages and the teaching of writing. There is, however, scant information on how computer-mediated peer response functions in the foreign language classroom. This dissertation investigated how college Spanish learners provided feedback to their peers and the impact of feedback on revision. It also examined the factors that influenced how …

Hearing Evaluation In Infants: An Update For Pediatricians, Janet E. Sullivan

USF Tampa Graduate Theses and Dissertations

This paper provides an overview of developmental timetables relevant to hearing and of current pediatric audiological techniques and practices. The first sections summarize structural and functional development of the auditory pathway and the development of primary auditory processing. These developmental sequences appear to follow similar paths in humans and animals. Speech and music perception involve more complex processing and are strongly influenced by experience. Hearing disorders affect the perception of complex sounds in a variety of ways, depending on the site(s) of lesions. Early onset hearing impairment, including conductive loss from chronic otitis media, can seriously impede language development.

Designing Interactive Multimedia For The Anthropology Exhibit Gallery, Kelley Curtis

USF Tampa Graduate Theses and Dissertations

Computer-based multimedia offer an alternative means of providing instruction to learners in two primary, yet disparate, ways. Multimedia can be used to convey information to learners, or alternatively, learners can make use of multimedia to impart information. One example of the use of multimedia technologies at the University of South Florida is an interactive computer kiosk installed in the Anthropology Exhibit Gallery. The development of the educational program featured on the kiosk's touchscreen computer is the subject of this paper.

The purpose of the kiosk's program was twofold: 1) to introduce the field of anthropology to university students and the …

Pipe Dreams And Primitivism: Eugene O'Neill And The Rhetoric Of Ethnicity, Donald P. Gagnon

USF Tampa Graduate Theses and Dissertations

Eugene O'Neill included within his vision of humanity a series of complex, emotionally and psychologically developed black characters. Despite critical controversy over his methods or effectiveness, from his eerily silent mulatto in "Thirst" through the grandiose incarnation of The Emperor Jones and the everyman of Joe Mott and The Iceman Cometh, O'Neill created characters of African descent that thrilled and infuriated critics and audiences alike.

A closer exploration of the issues involved in his portrayal of ethnically identified characters seems necessary, an exploration that does not limit itself to an interrogation of ethnicity per se in O'Neill's plays, but …

Effects Of Bilingualism, Noise, And Reverberation On Speech Perception By Listeners With Normal Hearing, Dashielle M. Febo

USF Tampa Graduate Theses and Dissertations

The accurate perception of spoken English is influenced by many variables, including the listener's native language, reverberation, and background noise. Few studies of speech perception by bilingual listeners have carefully controlled for second language proficiency and even fewer have presented speech in everyday listening environments that contain noise and reverberation. In the present study, detailed language background, language proficiency information, and individual language samples were collected and the speech stimuli were presented in a variety of quiet, noisy, and reverberant listening environments.

The effects of noise and reverberation on the perception of American English monosyllabic words was examined for two …

Body Image As A Function Of Colorism: Testing A Theoretical Model, Alicia V. Hall

USF Tampa Graduate Theses and Dissertations

A Covariate Structure Model was used to examine a possible relationship between colorism as a component of body image and global psychological functioning in the hypothesized model. Two hundred-fifty-five African-American women were recruited from undergraduate psychology and social work classes to participate in the current study from state and community colleges in the southeastern United States, and from social groups and church organizations. The results indicated that the hypothesized model was not a good fit to the data; therefore, the model was re-evaluated. The results of the analysis of the revised model indicated that the revised model was not plausible. …

The Effects Of Animated Textual Instruction On Learners' Written Production Of German Modal Verb Sentences, Elizabeth A. Caplan

USF Tampa Graduate Theses and Dissertations

This study investigated the effects of animation for a technology-assisted German grammar presentation on modal verbs. The premise was that many intangible concepts of dynamic grammar involve syntactic components that possess visuo–spatial characteristics. It was further speculated that these characteristics could be more effectively represented by animated versus static instructional presentations.

The supposition that animation would lend pedagogical advantage was supported by dual coding theory (Paivio, 1971, 1990), which posits two functionally separate representational systems, the verbal and the nonverbal, with dynamic mental imagery residing solely in the nonverbal system. The strength of dually coded information is that it is …

Selection Of Clinical Trials: Knowledge Representation And Acquisition, Savvas Nikiforou

USF Tampa Graduate Theses and Dissertations

When medical researchers test a new treatment procedure, they recruit patients with appropriate health problems and medical histories. An experiment with a new procedure is called a clinical trial. The selection of patients for clinical trials has traditionally been a labor-intensive task, which involves matching of medical records with a list of eligibility criteria.

A recent project at the University of South Florida has been aimed at the automation of this task. The project has involved the development of an expert system that selects matching clinical trials for each patient. If a patient's data are not sufficient for choosing …

The Diffusion Of New Media Scholarship: Power, Innovation, And Resistance In Academe, Judith R. Edminster

USF Tampa Graduate Theses and Dissertations

Electronic theses and dissertations (ETDs) are an evolving genre of graduate student research that is gaining widespread acceptance among universities in the international community. ETDs are also beginning to diffuse slowly among American universities; however, a number of issues continue to work against more rapid adoption among intitutions in the United States. This dissertation examines ETDs as an evolving electronic research genre by (1) historicizing the situated development of its predecessor, the traditional print dissertation, in nineteenth century German and American Universities; (2) reporting on the current state of the Networked Digital Library of Electronic Theses and Dissertations, an initiative …

Literacy, Technology, And Change: The Gates Of Hell, Janice R. Walker

USF Tampa Graduate Theses and Dissertations

In this dissertation, I first briefly examine the history of technology as it impacts on literacy practices, and especially the history of resistance to technological developments in the humanities. In so doing, I also briefly examine some of the possible ideological underpinnings of this resistance, including looking at some of the arguments proposed to counter it. More specifically, I consider how literacy practices, pedagogical practices, and assessment and gatekeeping practices in the field of composition studies impact on and are impacted by the intersection of computer technologies and our field. Finally, I offer some suggestions for ways in which our …

Acoustic And Perceptual Comparisons Of Imitative Prosody In Kindergartners With And Without Speech Disorders, Robin Harwell Rodriguez

USF Tampa Graduate Theses and Dissertations

This study investigated the affiliation of prosody with childhood articulation disorders. The Tennessee Test of Rhythm and Intonation Patterns, T-TRIP (Koike & Asp, 1981), was used to determine if kindergartners with linguistic (i.e. phonological) speech disorders, oral-motor speech disorders, or normal speech performed differently on imitative prosody tasks. Performance was assessed perceptually with T-TRIP overall and subtest scores, and acoustically with measurements of individual prosodic variables (amplitude, duration, and fundamental frequency) on selected items from the rhythm and intonation subtests. Perceptual and acoustic data were examined for characteristic patterns of performance by individual subjects and by groups.

An Application Of Artificial Neural Networks In Freeway Incident Detection, Sujeeva A. Weerasuriya

USF Tampa Graduate Theses and Dissertations

Non-recurring congestion caused by incidents is a major source of traffic delay in freeway systems. With the objective of reducing these traffic delays, traffic operation managers are focusing on detecting incident conditions and dispatching emergency management teams to the scene quickly. During the past few decades, a few number of conventional algorithms and artificial neural network models were proposed to automate the process of detecting incident conditions on freeways. These algorithms and models, known as automatic incident detection methods (AIDM), have experienced a varying degree of detection capability.

Of these AIDMs, artificial neural network-based approaches have illustrated better detection performance …
