Speech Reception Via Bone Conduction, Sherry G. Morris

Dissertations and Theses

The purpose of this investigation was to determine if the performance-intensity function for spondees delivered via bone conduction (using the Radioear E-72 and Pracitronic KH-70) differed from the performance-intensity function for air conduction (using TDH-39 earphones). A secondary consideration addressed in this study was the comparison of the discrimination scores using the three transducers. Performance-intensity functions for spondee thresholds were calculated on 12 normal hearing subjects using two bone conduction vibrators, the Radioear B-72 and Pracitronic KH-70, and TDH-39 earphones. Results indicated that there was no significant difference between the performance-intensity function of speech via bone conduction as compared to …

The Influence Of Situational Cues On A Standardized Speechreading Test, Maria Navarro Montserrat

Dissertations and Theses

The purpose of the present study was to determine the influence of situational cues on a standardized speechreading test in order to assess an individual's natural speechreading ability. The widely used, standardized Utley Lipreading Test was selected to which photoslides of message-related situational cues were added. The Utley Lipreading Test consists of two relatively equivalent test lists, containing series of unrelated sentences.

Effect Of Tinnitus Maskers On Speech Discrimination Among Those Wearing Tinnitus Maskers, John Alexander Chonka

Dissertations and Theses

The purpose of this study was to determine the effect(s) of tinnitus maskers and tinnitus instruments on speech discrimination utilizing a population of subjects who currently have tinnitus and are presently wearing these devices. The hypothesis which guided this investigation states that there is no difference between discrimination scores with and without tinnitus maskers. In an attempt to test this hypothesis, speech discrimination scores were obtained from 26 listeners both in quiet and in the presence of cafeteria noise, with and without use of their tinnitus maskers.

A Comparison Of The Articulatory Proficiency Between Stutterers And Nonstutterers While In A State Of Oral Sensory Deprivation, Clifford Saul Goldman

Dissertations and Theses

The purpose of this thesis was to determine if stutterers monitor speech production differently than nonstutterers while in a state of oral sensory deprivation. The specific questions asked were:

1. Does an imposed oral somesthetic feedback deficit hinder articulation proficiency more in a nonstuttering sample than in a stuttering sample?
2. If the articulation proficiency is deficient in both samples, does the nature of the errors differ between the two samples?

A Comparative Study Of Perceptual Ratings And Fundamental Frequency In Female And Male Esophageal Voices, Anne Terese Heinrich

Dissertations and Theses

This study proposed to determine if male and female esophageal voices were rated in the same manner by naïve listeners. Answers to the following questions were sought:

1. Is there a difference in the social acceptability ratings given to female esophageal voices compared to male esophageal voices, when the speakers are matched for speaking ability?
2. Does a relationship exist between the fundamental frequencies of female esophageal voices and ratings of social acceptability given by naïve listeners?
3. Does a relationship exist between the fundamental frequencies of male esophageal voices and ratings of social acceptability given by naïve listeners?
4. Do male and female …

A Study Of The Perceptual Parameters Of Voice In Aging Females, Barbara Ann Mathers

Dissertations and Theses

An interest in understanding the aging processes, as they relate to voice, has prompted research investigating physiological, acoustical, and perceptual attributes of the aging vocal mechanism. Recently, it has been demonstrated that perceptual parameters, in older male voices, differentiate speakers according to age estimations, as determined by a group of listeners.

The purpose of this study was to determine the perceptual characteristics of the female voice which are associated with perceived age, as contrasted to chronological age.

An Investigation Of The Consistency Of Judgments Regarding Successive Approximations Of /R/, Scott Robert Lane

Dissertations and Theses

This investigation sought to determine the accuracy and consistency of judgements made by three groups of judges, relative to successive approximations of /r/. The three groups were made up of speech pathologists, student trainees, and untrained individuals, respectively. It was the task of these judges to rank order three /r/ productions into the following categories: correct; partially correct; and incorrect. This task is basically the same as reinforcing approximations of /r/ within the therapy situation, and appears not to require extensive training. Many authors (Curry et al., 1943; Perrin, 1954; Oyer, 1959; Siegel, 1962; Irwin, 1965; and Elbert et al., …
