THE LARYNGEAL MUSCLE FOR SPEECH - Coggle Diagram
THE LARYNGEAL MUSCLE FOR SPEECH
Intensity
Physical measure of power or pressure
Increase in subglottal pressure will result an increase in intensity
Sustained Phonation
The purpose of adduction and abduction for speech.
Myoelastic Dynamic Theory
Myoelastic phase
Elasticity of vocal folds helps them close
Aerodynamic phase
Bernoulli effect helps vocal folds close
Sub-glottal pressure forces vocal fold apart
Depends on:
Tonic(sustained) contraction of adduction muscles
Maintain airflow
Maintenance of pressure gradient
Frequency
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.
Attack
Process of bringing vocal folds together(adduction) using muscles to begin phonation.
Glottal Attack
A forceful adduction of the vocal folds at the beginning of sound production
e.g. : orange
Simultaneous Attack
Adduction and onset of exhalation occurs together.
e.g. : judge
Breathy Vocal Attack
Airflow begins before phonation.
e.g. : Hairy
Pitch
The perceptual correlate of frequency and closely related to frequency.
As frequency increases, pitch increases, and as frequency decreases, pitch decreases.
Termination
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.
Vocal Register
Differences in mode of vibration of vocal folds
Glottal Fry
Crackly, popcorn quality of voice
Falsetto
high- pitched voice production
Model Register
Pattern of phonation used in daily conversation
