Variability Analysis Of Discrete Cosine Transform Coefficient (Dctc) Features For Speech Processing, Bingjun Dai

Electrical & Computer Engineering Theses & Dissertations

In this research, the variability of Discrete Cosine Transform Coefficient (DCTC) features was investigated. Additionally, a new pitch-synchronous processing method was explored to increase the stability of features and to reduce window effects when compared to the regular method. The noise sources that lead to feature variability were analyzed, and different smoothing methods were tested. It was found that longer frames, frequency warping, time smoothing of the log spectrum, and DCS level time smoothing, all help reduce DCTC variability and increase classification performance. The pitch­ synchronous method was implemented with Matlab. Important processing methods, including pitch period estimation, time­ domain …

Attention Effects On Distortion Product Otoacoustic Emissions With Contralateral Speech Stimuli, Genaya Kae Timpe

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of the present study was to investigate the effect of attending to a speech stimulus on the amplitude of the distortion product otoacoustic emission (DPOAE). The distortion product otoacoustic emission is a measurement of the activity of the inner ear, specifically the outer hair cells in the ear. The activity of the outer hair cells depends upon the auditory nervous system; when it is stimulated, the outer hair cell activity is modified. Normal outer hair cells will create a large DPOAE amplitude. When a stimulus is presented to the opposite ear, the auditory nervous system acts upon the …

The Effectiveness Of Hypermedia Training Vs. Traditional Classroom Instruction In Stuttering, Micheal Dean Baran

Dissertations and Theses

A study by Henri (1994) showed that fluency is one of two areas where speech-language pathology clinicians feel least prepared and Sommers and Caruso (1995) advocated improved training in fluency. The use of computer technology to train students in the field of stuttering has been proven effective in previous studies (Strang, Meyers & Hall, 1989; Tetnowski & Martin, 1996).

The purpose of this study was to further develop a hypermedia training module for stuttering identification and to determine whether this hypermedia training module was as effective as traditional classroom teaching methods.

Subjects in this study were undergraduate students in speech …

Career Orientation Levels In Adolescents : A Comparison Of Cleft And Noncleft Subgroups, Tara Darice Gaddis

Dissertations and Theses

The current research studied career orientation levels during adolescence utilizing previously collected cross-sectional data on 80 subjects. The subjects had participated in a study focusing on the ways in which clefting, gender, self-concept, mental ability, and socioeconomic status impact career development. Preliminary analysis of the data found that self-concept, mental ability, self-ratings of facial appearance, and desired level of future educational status were the factors most predictive of level of career development. In the initial analysis of the data, subjects, cleft and noncleft, who demonstrated high self-esteem, high mental ability, reported a more advanced level of desired higher education, and …

Speech Production Patterns Following Management Of Velopharyngeal Inadequacy, Debra Lynn Childs

Dissertations and Theses

This descriptive study investigated the pattern of speech sound production before and after surgical management of velopharyngeal inadequacy in two subjects. The research questions asked were: (a) What type of speech patterns do subjects referred for surgical management of velopharyngeal incompetence demonstrate presurgically? (b) What changes in the speech patterns of the subjects are observed in the immediate month following surgery for velopharyngeal incompetence? (c) Do these changes settle into a stabilized pattern of speech production by 4 months postsurgery?

The subjects' speech productions were audio recorded for analysis using the Broen CVC Probe to obtain imitated single word elicitations …

The Effect Of Diastema Closure On The Remediation Of Lateral /S/: A Case Study, Reta Price

Dissertations and Theses

An important morphological-marker and one of the most frequently occurring speech sounds in English, the /s/ phoneme is also one of the sounds most often in need of remediation. Often, air emission during /s/ production, a particularly stubborn, often residual production error, is not remediated through traditional treatment methods, and yet the negative effect /s/ distortions have on listeners has been well-documented.

The subject of this investigation was a forty-eightyear-old male who received treatment for a lateralized /s/ during grade-school. It was hypothesized that his exerting high anterior pressure to prevent air from escaping from a diastema between his two …

Concurrent Validity Of Mental Ability Screening Tools : A Comparison Of Normal Students’ Performance On The Kaufman Brief Intelligence Test And The Shipley Institute Of Living Scale-Revised, D. Melanie Peters

Dissertations and Theses

This study compared the Kaufman Brief Intelligence Test (K-BIT), a verbal and nonverbal mental ability screening tool, to the Shipley Institute Living Scale (SILS), a nonverbal screening tool of mental ability, as part of a larger, ongoing study which is examining the effects of orofacial clefts on early career maturity. In terms of general intellectual ability, the K-BIT and the SILS provide descriptive categories, percentile ranks, raw scores, standard error of measurement, standard scores, standardization and norms, subtest scores, and total scores. The K-BIT provides normative curve equivalents and stanines, which the SILS does not. The SILS provides abstract and …
