Anatomy and Physiology - Phonatory System

Increasing your vocal fundamental frequency will

Increase the longitudinal stress on the vocal folds

Contractions of the cricothyroid muscle results in elongation of vocal folds. If larger vocal folds generally predict lower F0, why does contraction of the cricothyroid muscle result in increases F0 for both men and women

Tensing and lengthening the vocal folds thinning out the vibrating mass

Why do we typically take a deeper breath when we plan on producing speech at an increased vocal intensity?

a deeper breath will result in greater elastic recoil forced and greater relaxation pressure in the lungs

The cricrothyroid joint

allows the thyroid cartilage to rock foward and downward to achieve vocal fold elongation

The cricothyroud joint results in cartilage movement upon contraction of the _______ muscle

cricothyroid muscle

The major regulator of intensity is

increased lung pressure

Why is the mean F0 of men's voices, on average, significantly lower than the mean F0 of women's voices?

men have larger vocal tracts than women

The conversion of aerodynamic energy into acoustic energy is called

phonation

The thyroid cartilage is also known as

the Adam's apple

The Bernoulli effects tells us

the air pressure will decrease as the air flows through the vocal tract in an area of constriction

The abduction and adduction of the vocal folds is achieved by movement of the

the cricoarytenoid joints

The space between in the vocal folds

the glottis

Fundamental Frequency is controlled by

the size of the vibrating mass

Lower Fundamental Frequencies of phonation are associated with

vibration of the vocal fold cover and body

The myoelastic aerodynamic theory of voice production tells us that

vocal fold vibration occurs passively due to the interaction of aerodynamics and the biochemical properties of the vocal folds tissues

AverageFundamental frequency during reading aloud has been measured at approximately

215 HZ for women and 115 HZ for men
