Phonation

two to four centimeters long, in the shape of a “V” that vibrate together when air passes through the trachea. They work together with the resonating chambers in the head, like the nose and mouth, to create sound. This process is known as phonation, “…The phonation process, or voicing, occurs

series of two-way repeated measures analysis of variance (Tay et al, 2012). The participant’s perceived effectiveness of the VFE (as reported in a post-training survey) was that the program had a positive effect on their voices (Tay et al, 2012). Phonation resistance training exercises (PhoRTE) is treatment adapted from the Lee Silverman Voice Treatment (Ziegler et al, 2014). PhoRTE uses Silverman’s “loud voice” approach while using “high-intensity phonatory exercises to overload the respiratory and

Introduction A crucial aspect of any speech assessment is the examination of a person’s vocal functioning. It is imperative to analyze vocal characteristics during and between phonation in order to rule out or identify possible causes and contributors of certain speech disorders, like stuttering. For instance, if a person displays increased tension at the level of the larynx, he or she may experience tense blocks and pauses during speech. This would indicate a necessity to practice laryngeal relaxation

Gradually and over time, this increased expiratory effort during phonation develops increased tension in the laryngeal musculatures which is responsible for the perceived dysphonia.This means that at least great part of dysphonia in our subjects is functional (muscle tension or hyperfunctional dysphonia). The primary cause

Ramig and colleagues (2001) performed a study to examine the long-term effects of using Lee Silverman Voice Treatment (LSVT) to improve vocal function in individuals with Parkinson’s Disease (PD). Ramig and colleagues (2001) compared LSVT to received respiratory therapy (RET) to control for extraneous variables. Subjects were recruited from a variety of sources which helped to reduce recruitment bias (Ramig et al., 2001). Individuals with any laryngeal pathology unrelated to PD were excluded from

1989; Baken & Orlikoff, 2000; Laver, 1980; Mooshammer; 2010). Modal voice is characterised as the quality that includes the range of fundamental frequencies normally used for speaking and singing; its laryngeal characteristic is a neutral mode of phonation, with moderate adductive tension (Laver, 1980). The Lx waveform of

LSVT was shown to improve areas of “loudness, articulatory precision and speech intelligibility, increased loudness levels in sustained phonation, conversation and reading and increased duration of sustained phonation and fundamental frequency range” (Wenke et al., 2008). LSVT has also shown an “increase in loudness that is associated with “greater inspiratory lung volumes in normal speakers and increased adduction of the vocal

Introduction Vocal fold polyps are common in the general population. They affect the vibratory vocal fold function resulting in significant dysphonia which are often surgically correctable. They are confined to the superficial lamina propria (SLP) of the vocal folds . Nowadays , phonomicrosurgery is the most common treatment of vocal fold polyps , and became a new standard of care to remove pathology in these cases without scar formation . The term phonomicrosurgery was introduced

Mean Speaking Frequency (MSF) or Speaking Fundamental Frequency (SFF) measures the average speaking frequency during: conversational speech, reading, counting, sustained phonation at the end of a given word, or sustained phonation at a comfortable pitch and loudness. A fundamental frequency analyzer is used to formulate MSF/SFF. • The rationale for using a MSF measure is that it would provide measurements of the average rate of vocal fold vibration

As previously reported, Ms. Noid referred herself for a voice evaluation because of a chronic, persistent dysphonia characterized by “severe hoarseness and breathiness.” She had a recent ENT report indicating a “left adductor vocal cord paralysis” which is paralyzed in the intermediate position. Furthermore, she has reported that her symptoms have persisted for 18 months, eliminating the possibility of an idiopathic etiology. After completing a voice evaluation, recommendations for medical clearance
