THE LARYNGEAL MUSCLE FOR SPEECH
Physical measure of power or pressure
Increase in subglottal pressure will result an increase in intensity
The purpose of adduction and abduction for speech.
Myoelastic Dynamic Theory
Elasticity of vocal folds helps them close
Bernoulli effect helps vocal folds close
Sub-glottal pressure forces vocal fold apart
Tonic(sustained) contraction of adduction muscles
Maintenance of pressure gradient
A measure of a cycle of vibration per unit time. For voice, it is equal to the number of times the vocal folds open and close per second.
Process of bringing vocal folds together(adduction) using muscles to begin phonation.
A forceful adduction of the vocal folds at the beginning of sound production
e.g. : orange
Adduction and onset of exhalation occurs together.
e.g. : judge
Breathy Vocal Attack
Airflow begins before phonation.
e.g. : Hairy
The perceptual correlate of frequency and closely related to frequency.
As frequency increases, pitch increases, and as frequency decreases, pitch decreases.
Process of fold retraction(abduction) to end phonation.
When phonation stops, the vocal folds out of the airstream - reduce the turbulence, using muscular action – the vocal folds stop vibrating.
Differences in mode of vibration of vocal folds
Crackly, popcorn quality of voice
high- pitched voice production
Pattern of phonation used in daily conversation
