The Effect Of Different Warm-Up Durations On Subjective And Objective Measures Of Singing In Choral Singers Over The Age Of 55, Jeremy A. Chesman

MSU Graduate Theses

Choral singing is a popular activity in the United States. Choral singers are often encouraged to warm up vocally before they sing. Considering voice conditions, like presbyphonia, that can develop shortly after retirement, more research about vocal warm-ups is needed for those over the age of 55. This study assesses the effects of various durations of vocal warm-ups on subjective and objective measures of the singing voice using a within-groups design with randomized condition order. Nine participants performed vocal warm-ups for 0, 5, 10, and 15 minutes. A song sample was then recorded and sent to two expert raters who …

The Lived Experiences Of Transmasculine Speakers: A Phenomenological Investigation Of Vocal Quality And Function In Relation To Gender, Micah Wylie

Graduate Theses and Dissertations

The objective of this study was to learn how transmasculine individuals perceive the quality and function of their voices, and how those perceptions influence how they experience gender identity and communicate with others. This qualitative study adopted a hermeneutical phenomenological approach that involved using content analysis and thematic analysis to describe and interpret phenomena. This approach assumes that the researcher is not biased, but is a part of the world being studied and, therefore, understands the phenomenon by interpretive means. Saturation was achieved when all relevant information was introduced, and patterns of information had been identified. Sixteen interviews were conducted. …

Outcome Measures And Demographic Representation Of Voice Studies Of Transgender People: A Scoping Review, Rachel Anthony

One significant healthcare service is gender-affirming voice services, which is performed by a Speech-Language Pathologist. The purpose of this study is to perform a scoping review of voice production studies in transgender individuals with a focus on outcome measures and demographic characteristics. Search terms were identified and then applied across three different databases. The results of these databases were cross-checked for duplicates. A criterion was established, and studies were screened by reading the title, and abstract. Relevant articles were uploaded to RefWorks and lastly scanned by …

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. …

Speech-Evoked Brain Activity Is More Robust To Competing Speech When It Is Spoken By Someone Familiar, Emma Holmes, Ingrid S. Johnsrude

Communication Sciences and Disorders Publications

When speech is masked by competing sound, people are better at understanding what is said if the talker is familiar compared to unfamiliar. The benefit is robust, but how does processing of familiar voices facilitate intelligibility? We combined high-resolution fMRI with representational similarity analysis to quantify the difference in distributed activity between clear and masked speech. We demonstrate that brain representations of spoken sentences are less affected by a competing sentence when they are spoken by a friend or partner than by someone unfamiliar—effectively, showing a cortical signal-to-noise ratio (SNR) enhancement for familiar voices. This effect correlated with the familiar-voice …

The Acoustic Effect Of Masks On Speech And Singing, Anna Birkemeier

Honors Projects

Objectives / Introduction:

Mask-wearing has become commonplace for the public during the SARS-CoV-2 (COVID-19) pandemic. This has caused communication difficulties such as muffled speech, causing a lowered speech intelligibility and worse audibility. The purpose of this study was to determine the acoustic filtering effects of various masks.

Methods / Study Design:

The acoustic effects of a surgical mask, a Singer’s Mask, and an N95 mask were obtained. A single subject spoke (and repeated) the vowels /a,i,u/ and the consonants /s, ∫/, and sang the vowels on G4 and C5 with and without the masks, respectively. Spectra of the vowels and …

Voice Therapy: Racial Disparities In Adherence And Clinically Significant Outcomes, Amber D. Burks

LSU Master's Theses

Voice therapy is evidence-based, behavioral intervention that can reduce functional and organic voice disorders. Despite its proven effectiveness, non-adherence to voice therapy is still an issue. Research shows that an estimated 65% of patients who initiate voice therapy drop out before reaching therapeutic goals. Voice therapy outcomes are largely dependent on patients’ adherence to treatment regimens, but there is limited information concerning factors that may be associated with voice therapy adherence and therapeutic outcomes for patients who successfully complete voice therapy.

The purpose of this study was to investigate which demographic factors could be associated with higher adherence rates to …

Voice-Related Experiences Of Nonbinary Individuals (Veni) Development And Content Validity, Grace Shefcik, Pei-Tzu Tsai

Faculty Research, Scholarly, and Creative Activity

Transgender individuals may seek a variety of gender-affirming health and educational services, including voice modification from speech-language pathologists. Measuring the client's self-perception of their communication experiences is crucial for providing client-centered services and measuring outcomes. However, there is currently no validated assessment tool for the nonbinary population, a part of the transgender population. This study explores the voice-related concerns and experiences among the nonbinary population to create a valid measure of their self-perception of voice. Ten nonbinary individuals were surveyed about their voice-related concerns and experiences. A thematic analysis of the responses led to the development of the questionnaire, titled …

Lifting The Heavy Vocal Load: Slps And Their Vocal Habits, Sydney Sedlock

Murray State Theses and Dissertations

Novice speech-language pathologists (SLPs) are a vulnerable population that is at-risk for dysphonia. Previous literature has highlighted the high vocal-demand occupations of teaching and entertaining but there is minimal research to understand the prevalence of dysphonia in SLPs. The purpose of this investigation was to determine the prevalence of vocal fatigue and vocal loading in novice SLPs in western Kentucky to increase awareness of the vulnerability for dysphonia in this population. This investigation was descriptive in nature using a survey format and was sent to SLPs in the western Kentucky region. A total of 21 SLPs responded to the survey. …

Demonstrable Effect Of Vocal Changes On Singing Voices Of Post-Menopausal Women, Haley K. Griffith

Senior Honors Projects, 2020-current

There is little research concerning the impacts of menopause on the female singing voice, and few research studies examine any treatment methods or exercises to help sustain vocal quality throughout and after menopause. To determine areas in which more detailed studies could be completed, I completed a thorough literature review of current research studies that investigate relationships between menopause and the voice. Many studies examined vocal symptoms of menopause, such as a lowered fundamental frequency (F0) and decreased vocal quality. However, there exists no formally researched or published vocal exercises that help to mitigate these menopausal voice symptoms.

In response, …

The Use Of Smartphone Apps As A Supplement To Transgender Voice And Communication Therapy, Maura Philippone

Honors College

This university IRB-approved thesis follows a case study research design and investigates the effectiveness of the app “Voice Analyst” as a supplement to transgender voice and communication therapy. It is hypothesized that the use of “Voice Analyst” outside the clinic will enable participants to make greater progress and to increase their ability to retain their progress. The participants are four transgender women who want to raise the pitch of their speaking voices. The participants are asked to record themselves reading “The Rainbow Passage,” and their data are tracked in a spreadsheet. “The Rainbow Passage” is the standardized passage used for …

Average Speech Directivity, Samuel D. Bellows, Claire M. Pincock, Jennifer K. Whiting, Timothy W. Leishman

Directivity

Speech directivity describes the angular dependence of acoustic radiation from a talker’s mouth and nostrils and diffraction about his or her body and chair (if seated). It is an essential physical aspect of communication affecting sounds and signals in acoustical environments, audio, and telecommunication systems. Because high-resolution, spherically comprehensive measurements of live, phonetically balanced speech have been unavailable in the past, the authors have undertaken research to produce and share such data for simulations of acoustical environments, optimizations of microphone placements, speech studies, and other applications. The measurements included three male and three female talkers who repeated phonetically balanced passages …

Voice Feminization: Voice Therapy Vs. Surgical Intervention: A Systematic Review, Carson Leon-Gambetta, Ruth Huttner, Amanda Matyas

Communication Sciences and Disorders: Systematic Review Publications

Abstract

Purpose: Transgender individuals often seek to alter their vocal characteristics. For Male to Female (MtF) transgender individuals, attaining a feminine voice may be particularly challenging. The objective of this systematic review is to determine whether MtF transgender individuals who receive voice feminization therapy alone or Wendler’s Glottoplasty (WG) surgical intervention with subsequent voice therapy yield greater outcomes in frequency and self-perception.

Method: A systematic review of the literature was conducted by using PubMed and Ovid to search terms pertaining to voice feminization. The articles were reviewed and appraised by the authors for inclusionary criteria, exclusionary criteria, and quality. Inclusionary …

The Effectiveness Of The Natural Ear On Adults Ability To Accurately Match Pitch, Kendra Nicole Rosales

Open Access Theses & Dissertations

Background: Many theories, such as oral motor, perceptual, and sensorimotor deficits, have been posited to explain inaccurate pitch matching abilities. The current study identifies with the sensorimotor deficit theory and found it to be the most plausible explanation for inaccurate singing abilities. The Natural Ear (NE) program was designed to process voice productions in real-time and filter out the discordant harmonics, allowing a person to hear only their F0.

Purpose: The purpose of this study was to examine the effectiveness of the Natural Ear program in increasing pitch matching accuracy in singers.

Methods: A total of 50 participants were included …

The Effects Of Dance Therapy On Voice In Patients With Parkinson's Disease In A Multicultural Population, Ivon N. Ramirez

Theses and Dissertations

Current literature suggests that dance therapy in individuals with Parkinson’s disease shows noticeable improvement in motor functions, for example gait and balance improvement. Additionally, patients with Parkinson’s disease who participate in dance therapy may perceive positive benefits on their quality of life. Therefore, it is believed that increases in core support and improvements in posture, as a result of dance therapy, will have effects on the voice in patients with PD.

This thesis pulls from literature supporting treatment approaches in the field of speech-language pathology for voice patients with Parkinson’s disease. The aim of this study was to evaluate the …

Changes In Fundamental Frequency Of Voice In A Group Of Transwomen Following Voice Modification Therapy, Emily Marquez

Open Access Theses & Dissertations

The term transgender refers to an individual that identifies with a gender that is different to the one given at birth. Individuals that are transgender experience conflict between the gender the individual identifies with and the sex they are born with. Individuals that are transgender may elect to go through a transition process so that their outward appearance is congruent with their gender identity. Part of the transition process may include voice modification therapy. Transgender individuals may seek voice modification therapy so that the outward appearance matches the voice. However, there is limited information regarding the efficacy of traditional voice …

The Role Of The Speech-Language Pathologist When Working With Clients Who Are Transgender: A Guide Of Gender Identity And Cultural Competency, Brett Welch

Theses and Dissertations

It is within the scope of practice of a speech-language pathologist to work with a client who is transgender for voice. However, regardless of the setting, a speech-language pathologist is likely to encounter a person who is transgender on their caseload. The American Speech-Language-Hearing Association mandates that all of its members be culturally competent when working with clients from different cultural backgrounds, including those from the lesbian, gay, bisexual, transgender, and queer community.

This thesis pulls from sociological, linguistic, and queer theory literature to provide an in-depth understanding of identity, gender, and transgender identity formation. With this nuanced understanding of …

Vocalization Subsystem Responses To A Temporarily Induced Unilateral Vocal Fold Paralysis, Daniel J. Croake

Theses and Dissertations--Rehabilitation Sciences

Healthy voicing is thought to be dependent on a dynamic balance of three interactive subsystems: respiration, phonation, and resonance. Theoretically, multiple patterns of subsystem interactions likely underlie healthy voice production; however surprisingly little quantitative data exists defining the nature of these subsystem production patterns and interactions across individuals.

The central aim of this study was to quantify the interactions of the vocalization subsystems in a non-perturbed and perturbed condition (induced unilateral vocal fold paralysis) in 10 vocally healthy participants. Respiratory inductance plethysmography, laryngeal aerodynamics, and acoustic formant data were used to measure the proportional contributions of, and changes to, the …

Speech Function In Persons With Parkinson's Disease: Effects Of Environment, Task And Treatment, Carrie E. Rountrey

Dissertations, 2014-2019

Parkinson’s Disease (PD) is a degenerative neurological disease affecting aspects of movement, including speech. Persons with PD are reported to have better speech functioning in the clinical setting than in the home setting, but this has not been quantified. New methodologies in ambulatory measures of speech are emerging that allow investigation of non-clinical settings.

The following questions are addressed: Is speech different between environments in PD and in healthy controls? Can clinical tasks predict speech behaviors in the home? Is treatment proven effective by measures in the home? What can we glean from methods of measurement of speech function in …

Two groups of adolescents and young adults were analyzed- one group consisting of 20 individuals with Friedreich's ataxia who were compared to 20 individuals with normal voice (control participants). A trained group of 10 graduate students listened to 132 vowel samples (3 vowels X 40 participants, + 12 samples (10%) for reliability purposes) for a total of 132 perceptual judgments. The students listened to the samples which were randomized onto Dell computers (Optiplex 755) and played through headphones …

A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys

Masters Theses

A variety of terms exist for describing tone quality in singing, and voice scientists, voice therapists, teachers of singing, and students of singing use different terms to describe the same sound. One aspect of tone quality is tone placement. Teachers of singing often rely on imagery and imitation to elicit correct tone placement from students of singing. More concrete data about what produces forward and backward tone placement could supplement singing teachers’ current practice of using imagery and imitation to elicit a desirable tone quality. This study examined forward and backward tone placement to determine the articulatory gestures and acoustic …

Evaluation Of Motor Speech And Intervention Planning For Children With Autism, Marcil J. Boucher

Open Access Dissertations

Autism affects 1 in 88 children (Center for Disease Control, 2009), approximately 50% of whom will not develop speech (Seal & Bonvillian, 1997). Some researchers hypothesize that these difficulties in developing oral speech reflect underlying motor speech deficits (Prizant, 1996; Seal & Bonvillian, 1997; Szypulski, 2003; Andrianopoulos, Boucher, Velleman & colleagues 2007-2010). This investigation sought to identify the presence or absence of specific motor speech markers in ASD through an innovative best-practice protocol for assessing the speech, prosody, and voice quality of individuals with ASD.

The study focused on apraxic-like motor planning/programming features and dysarthric-like motor execution features in imitated, …

Aerodynamic And Acoustic Features Of Vocal Effort, Allison Rosenthal

Speech-Language Pathology - Theses

Many voice disorders are associated with an effortful voice; however, there have been very few studies that have examined the physiological changes that contribute to this sense of effort. Determining the factors that contribute to change in vocal effort may help clinicians to effectively target these variables when working with people with voice disorders so that voice improvement is accompanied by decreased vocal effort after treatment. Prior research has shown that alterations in aerodynamic and acoustic variables are often associated with voice disorders involving increased muscular effort, and change in these variables is correlated with abnormal voice qualities. The current …

Attitudes About Voice And Voice Therapy Among Transgender Individuals, Stefanie E. Hays
