Effect Of Flow Phonation Voice Exercises On Vocal And Aerodynamic Measures In Undergraduate Student Singers, Jorge A. Diaz

FIU Electronic Theses and Dissertations

This study examined the effects of Flow Phonation Voice Exercises on vocal measures in undergraduate student singers. Whereas these exercises have provided positive outcomes in individuals with vocal hyperfunction, the use of these exercises in potentially enhancing the singing voice has not been explored. A total of 10 participants were randomly assigned into an experimental group (n = 6), that received 5 sessions of the Flow Phonation Voice Exercises across 5 weeks, and a control group (n = 4) which did not receive the treatment. Changes in auditory-perceptual, acoustic, subjective respiratory, quality-of-life and fatigue related measures compared across two groups. …

Perceptions Of Speech-Language Pathologists On Childhood Bilingualism, Sherlie V. Paz

FIU Electronic Theses and Dissertations

A total of 320 Speech-Language Pathologists (SLPs) completed a survey stating their perceptions on childhood bilingualism for typically developing children and children with disabilities. Based on the number of significant responses, 292 participants were analyzed utilizing a binary logistic regression to identify whether SLPs thought childhood bilingualism was advantageous or neutral, while incorporating the predictors of bilingual status and bilingual education received. Additionally, a content analysis was conducted on 173 participants who chose to respond to an open-ended question stating their additional perceptions on childhood bilingualism. Results revealed that bilingual status did not predict the probability of an advantageous perception …

The Effects Of Acidic Foods On Vocal Quality Of Vocally Healthy Individuals, Melissa Barbieri

FIU Electronic Theses and Dissertations

The purpose of the current study was to examine the relationship between the consumption of acidic liquids on the vocal quality of vocally healthy individuals. Acidic foods and liquids are known to be possible causes of common voice disorders because of their putative effect on systemic hydration of the vocal folds impacting their viscoelastic properties and eventually affecting vocal quality, as they are found in over 50% of dysphonic patients (Karkos et al., 2007). This study investigated the effects of acidic foods on vocal quality in comparison to the effects of non-acidic/alkaline beverages in vocally healthy individuals.

“Perceptual Training Of Arabic Consonants In English-Speaking Quran Learners, Amanda A. Smith

FIU Electronic Theses and Dissertations

In the American Muslim community, accurate perception of classical Arabic phonemes is of importance in order to understand and recite the Quran, which is read, studied, and recited in its original language. High variability phonemic training (HVPT) develops new phonemic categories by exposing learners to a variety of productions of new phonemes. In this study, HVPT therapy was used to train accurate perception of Arabic consonants that do not exist in English. Results indicated significant improvement in perception of Arabic consonants (pre-test mean = 58.5%, post-test mean = 64.8%, difference = 6.3%, p-value = .01). Improvement was seen for the …
