Nonspeech Laryngeal Function • Abdominal fixation • Capturing air within the thorax to provide the muscles with a structure to push/pull • Similar to a cough • Take in a large breath, tight adduction of the vocal folds • Thorax becomes a rigid frame • Some air may escape through the adducted vocal folds and you may “grunt” when lifting something heavy, Nonspeech Laryngeal Function • Breathing • Normal breathing requires the vocal folds to be abducted • During forced exhalation (like when exercising)- the need for air causes you to increase the abduction of the vocal folds, Laryngeal Function for Speech • Bernoulli Effect • This explains how we maintain phonation • Need a constant volume flow of air • Vocal folds become a source of turbulence in the vocal tract • Effects of constricting a tube during air flow • As it flows through the constriction- the rate (velocity) of flow increases, however, the pressure decreases • Vibration of the vocal folds is the product of airflow interacting with the tissue in the absence of repetitive muscular constriction, Laryngeal Function for Speech • Attack • Process of bringing vocal folds together to begin phonation, requires muscular action • Simultaneous vocal attack-coordinate adduction and onset of respiration so that they occur simultaneously (i.e. ARTICULATOR.

Phonation is the production of vocal sound and speech. Increasing the knowledge of the anatomy and physiology of phonation amongst voice professionals through engagement at Notre Dame Senior School, Cobham. • Vocal folds are held in place- it is not the product of repeated adduction and abduction- muscle spindles embedded within the thyrovocalis and thyromuscularis serve the function in holding sustained posture, Vocal Register • Mode of vibration- pattern of activity that the vocal folds undergo during a cycle of vibration • Three registers-differences in the mode of vibration of vocal folds • Modal register • Glottal fry or pulse register • Falsetto, Modal Register • Pattern of phonation used in daily conversation • Vertical mode of phonation is when the vocal folds open from bottom to top and close from bottom to top- like a wave • Primary frequency of vibration- vocal fundamental frequency • Anterior-Posterior dimension of phonation- vocal folds open from posterior to anterior but closure is made by contact at the medial edge, Glottal Fry • Also called “fry, pulse, and straw bass” voice • Crackly, popcorn quality of voice • Low in pitch, sounds rough • Frequencies as low as 30 Hz to 80-90 Hz • Low subglottal pressure and tension of the vocalis is reduced • Vibrating margin is flaccid and thick • Lateral portion of the vocal folds is tensed – strong medial compression with short, thick, vocal folds and low subglottal pressure • Syncopated mode of vibration- a secondary beat for every cycle- the vocal folds don’t just vibrate slower, but differently, Falsetto • Vibratory pattern that varies from modal production • Vocal folds lengthen and become thin and “reed like” • Vibrate along the tensed, bowed margins • Make contact only briefly and the degree of movement is reduced • Thin, high- pitched voice • Whistle register- above falsetto- product of turbulence on the edge of the vocal fold- frequencies as high as 2500 Hz, Pressed and Breathy Phonation • Pressed phonation • Medial compression is greatly increased • Increase in stridency or harsh quality • Increase in abuse to the voice • Stronger, louder phonation • Forceful adduction often results in damage to vocal fold tissue, Pressed and Breathy Phonation • Breathy voice • Vocal folds are inadequately approximated • Vibrating margins permit excessive airflow between then • Inefficient and causes air wastage • May signal the presence of vocal nodules, polyps or laryngeal cancer, Whispering • Not a phonatory mode • No vibration of the vocal folds • Vocal folds are partially adducted and tensed to develop turbulence in the airstream • The turbulence is the noise you use to make speech • Arytenoid cartilages are rotated slightly in but are separated posteriorly • No voicing, however, it is strenuous and can cause vocal fatigue, Intensity • Relative power or pressure of an acoustic signal, measured in decibels (dB) • Amount of pressure exerted by the sound wave, Ventricular Phonation • False or ventricular vocal folds are technically unable to vibrate for voice • In some instances- clients may use ventricular phonation as an adaptive response to severe ocal fold dysfunction • Forces the lateral superior walls close together • Phonation is deep, raspy, Sustained and Maximum Phonation • P. 237 • Sustain /ah/ • Sustain /s/ • Sustain /z/, Pitch • Psychological correlate of frequency • As frequency increases, pitch increases • Vocal folds tend to vibrate at the same frequency when mass and elastic elements remain constant • Frequency of vibration changes when mass and elastic elements change, Optimal Pitch • Vocal fold vibration that is most appropriate for an individual • Most efficient for a pair of vocal folds • Considered 1/4th octave above the lowest frequency • Can be estimated from a throat clearing • Varies from gender and age • Females average 212 Hz, Males 132 Hz, Habitual Pitch • Frequency of vibration of vocal folds that is habitually used during speech • Ideally this would be the same as optimal pitch • The choice to use an abnormally higher or lower fundamental frequency is often not a conscious decision • When forcing vocal folds to extremes of their range of ability- greater effort and physical fatigue, Average Fundamental Frequency • Frequency of vibration of sustained phonation or conversational speech • Reflects habitual pitch over a longer averaging period • Use conversational speech or reading tasks to accurately reflect • Pitch range- difference between the highest and lowest frequencies- capable of approximately two octaves, Pitch Changing • Stretching and tensing the vocal folds • Use the cricothyroid and thyrovocalis muscles • Changeable elements are tension, length and mass through elongation • Cricothyroid- thyroid tilts down, lengthening the vocal folds and increasing fundamental frequency • Thyrovocalis- pulls cricoid and thyroid closer, Pitch changing • Posterior cricoarytenoid- has muscle spindles that moitor and maintain tonic muscle length • Cricothyroid makes the gross adjustment, Thyrovocalis fine tunes the adjustment • Increased subglottal pressure is a response to the increased tension • Mass is rearranged by lengthening or shortening • Relaxing the vocal folds- contraction of the thyromuscularis- folds are relaxed and shortened becoming more massive and less tense, Intensity • Loudness is the pscyhological correlate of intensity • Physical measure of power or pressure • Increase the vigor with which the vocal folds open and close • Subglottal pressure and flow provide the energy • Increase subglottal pressure to increase vocal intensity, Changing Intensity • Increased medial compression of vocal folds • Vocal folds are tightly compressed • Takes more force to blow them open • They close more rapidly • Stay closed because they are tightly compressed Intensity and Frequency are controlled independently, however, it is difficult to increase intensity without increasing pitch unless you are trained.
