Question 1

What determines the intensity at each harmonic in vowel production?

A. nothing
B. respiration
C. vocal folds
D. vocal tract

Answer 1

D. vocal tract

The formant structure of the vocal tract causes those individual energy components (harmonics) to be either strengthened or weakened in the radiated sound. The first two formants are called the vowel formants

Question 2

Vowels are produced with a relatively open vocal tract. There will always be a fundamental frequency and harmonics for vowels. We perceive vowel differences by the relationship between formants. How are vowels perceived?

A. the spacing of formants
B. fundamental frequency
C. height of each formant
D. height of each harmonic

Answer 2

A. the spacing of the formants

Question 3

When force is applied to surface mass per unit area, it is called

Answer 3

pressure

Question 4

When force is applied to surface mass per unit area, it is called

Answer 4

elasticity and inertia

Question 5

According to the myelastic-aerodynamic theory, vibration of the vocal folds depends on which four of the following factors?

Answer 5

-elasticity
-airflow
-pressure
-muscle action
