Examining The Effect Of Training Using Natural And Noise-Vocoded Sentences On Noise-Vocoded Speech Perception In Normal-Hearing Listeners, Alexis Leiderman

Dissertations, Theses, and Capstone Projects

Auditory training has been shown to be an intervention strategy that may improve speech perception abilities in individuals with and without hearing loss. Within the cohort of individuals with hearing loss, auditory training has also been shown to have an improvement on speech perception in cochlear implant users. In several training studies, normal-hearing listeners have been exposed to noise-vocoded speech using auditory training paradigms to mimic how cochlear implant users may in turn be affected by these paradigms. These studies have highlighted certain areas for improvement in speech perception abilities based off of the training paradigms put in place. Several …

Analysis Of Electrophysiological Markers And Correlated Components Of Neural Responses To Discourse Coherence, Kurt M. Masiello

Dissertations, Theses, and Capstone Projects

Constructing meaning from spoken language is invaluable for learning, social interaction, and communication. In clinical populations with developmental disorders of speech comprehension, the severity of disruption can persist and vary from limiting occupational opportunities to lower performance outcomes. Previous research has reported an event-related potential (ERP) neural positivity over right hemisphere lateral anterior sites in response to semantic and discourse processing. Although useful as a marker for clinical populations of autism spectrum disorder (ASD) and developmental language disorder (DLD), little is understood about the dynamics and neural sources of this biological marker. In addition to traditional methods of ERP analysis, …

Late Talkers: Maternal Input And Attention Allocation In Mother–Child Dyad Play, Toby B. Mehl

Dissertations, Theses, and Capstone Projects

Late talkers (LT) are two-year-old children with expressive language delays, who do not yet have a lexicon of fifty words, and do not combine words. Maternal child-directed language to these children, termed ‘maternal input’ may influence their language learning. The first aim of this study was to examine the relationship between a child’s language, as measured by expressive vocabulary, and the child-directed speech by the mother of the child. Maternal input to late-talking children was compared to the maternal input presented to two typical language matched groups: an age-matched group of children (AM) and a vocabulary-matched group of children (VM) …

This includes not only otological diseases, but multisystem disorders that affect the auditory system. While an abundance of diagnostic audiological information on various disorders and their impacts are available, there exists a gap in the availability of condensed and accessible diagnostic information for everyday use. The goal of the resulting diagnostic pocket guide is to provide …

Monolingual Versus Bilingual Use Of Context To Facilitate Speech Recognition In Background Noise: A Systematic Review, Rachel Abucasis

Dissertations, Theses, and Capstone Projects

Introduction: Previous literature has shown that bilingual listeners face more challenges than monolinguals during speech recognition in adverse listening conditions. As noisy environments degrade the acoustic stimuli and leave the listener with a partial or ambiguous signal to pair to a lexical representation, it is not possible to do so with the acoustic and phonological features alone. Bilinguals consistently use a significant amount of their cognitive resources during the early stages of speech processing, partially due to their need to navigate between the two languages. With exhaustion of most of their cognitive resources, there is limited capacity available to use …

Audiologists' Perspectives On Noise Induced Hearing Loss, Rachael L. Cleary

Dissertations, Theses, and Capstone Projects

Excessive noise has long been established in the literature as a prevalent workplace hazard. The high prevalence of occupational noise-induced hearing loss (NIHL) has led to high economic costs and has produced many physical and mental health effects on workers exposed to occupational noise. Standards set by OSHA are implemented in the workplace in order to protect employees. Despite these regulations set by OSHA, millions of workers in the United States are still exposed to excessive occupational noise, with limited use of hearing protection. The high prevalence of occupational NIHL and low use of hearing protective devices (HPDs) brings into …

Cross-Linguistic Morphosyntactic Influence In Bilingual Speakers Of Jamaican Creole And Jamaican English, Taryn R. Malcolm

Dissertations, Theses, and Capstone Projects

Bilingualism in Jamaica is of considerable consequence, as most individuals are early bilinguals, speaking both a variety of Jamaican Creole (JC) from birth and having standardized English (sE) as the language of instruction in education. Immigrants from Jamaica to the United States are an ideal population to examine how cross-linguistic influence (CLI) impacts morphosyntax as JC and sE differ in morphosyntactic constructions, including verb tense- marking, subject-verb agreement, and copula use. While much of the work in the field of CLI has examined spoken language pairs with varying degrees of similarity (or difference) between the languages, examining CLI in a …

Efficiency Of The Acoustic Change Complex For Various Stimulus Presentation Strategies In Infants, Lisa Goldin

The goals of this study were: 1) To determine if the ACC can be elicited in infants, and 2) To establish whether eliminating the silent interval between stimuli and using a continuously alternating stimulus is more efficient in infants than the traditional interrupted stimulus presentation method. If the continuously alternating stimulus is more efficient, then 3) To determine why the continuously alternating stimulus is more efficient.

Twenty-one infants aged 2 months to 13 months old served as …

Acoustic Changes Following Clear Speech Intervention, Polina Shuminsky

Dissertations, Theses, and Capstone Projects

Studies have shown that the speech perception of individuals with hearing loss and other perceptual difficulties improves when talkers deliberately use clear speech. Several investigations have reported increased recognition scores of 11 to 34 percentage points for various listener groups in response to naturally produced clear speech. Studies show that clear speech production is highly variable across talkers. Therefore, a consistent method of eliciting clear speech that leads to more unified and consistent production outcomes is needed. Limited evidence suggests that a training program on how to speak clearly may yield greater listener benefit than clear speech produced naturally. The …
