Chapter 3: Physiology of Phonation (part 3) 34 terms. • 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. 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. If so, share your PPT presentation slides online with PowerShow.com. 27 terms.
