A Comparison Of The Expressive Speech Of Profoundly Hearing-Impaired Children : "Hearing Aids On" Versus "Hearing Aids Off", James Allen Henry

Dissertations and Theses

This investigation was conducted to determine whether the removal of hearing aids from these children for eighteen hours (+ 1/2 hour and including sleep time) would result in reduced speech intelligibility as perceived by a panel of listening judges who were unfamiliar with the speech of the deaf.

The Expressive Acquisition Of Locative And Directional Prepositions By Severely-To-Profoundly Hearing Impaired Children, Joann Warlick

Dissertations and Theses

Prepositions are important for the syntactical structure of the sentence and also to relate meaning, particularly meaning associated with concepts of place and time. Expressive acquisition of function words, including prepositions, is significantly delayed in the hearing impaired population. Yet, acquisition sequence for expressive prepositions has not been determined for this population.

The purpose of this study was to investigate the oral expressive acquisition of locative and directional single word prepositions in severely-to-profoundly hearing impaired children. The question this study sought to answer was: At what age levels are seventeen locative and directional single word prepositions expressively acquired by severely- …

Acoustical And Perceptual Correlates Of Vocal Effort In Normal Hearing And Hearing-Impaired Children, Corinne A. Thomas-Kersting

Dissertations and Theses

The present study was designed to investigate the perceptual and spectrographic features of vocal effort in the speech of severely to profoundly hearing-impaired children and their normal hearing agemates. Recorded vowel and speech samples were obtained from ten normal hearing children, ten severely to profoundly hearing-impaired children attending Oral/Aural educational programs, and eight severely to profoundly hearing-impaired children attending Total Communication programs. The degree of perceived vocal effort for vowels and speech was evaluated, using a nine point equal-appearing-interval scale. In order to obtain a physical measurement for vocal effort, a digital wave analyzer was used to produce vowel spectra, …
