Voicing Sept 27/ Oct 2

Question 1

what are the 3 primary parameters to consider for the process of voicing

Answer 1

1. width of the glottis (how far apart the vocal folds are)
2. whether theres a need to raise or lower the larynx (i.e., glotalic airstream mechanisms)
3. Timing duration that a position is held/ timing relative to oral movements.

Question 2

Process of Voicing: Glottal action. What causes (doesn’t cause) our vocal folds to contract and expand

Answer 2

• this is not a neural command as the neural impulses are not fast enough for voicing.
• we move the muscles in the larynx to create a condition where vibration is possible if air floes through with the right amount of pressure.

Question 3

what is Bernoulli’s principle

Answer 3

the faster the air flows the lower the pressure gets

Question 4

How does bernoulli’s principle in terms of voicing

Answer 4

• Air starts flowing through the vocal folds and the vocal folds are blown apart
• the pressure on the vocal folds is lower than the immediate sub and supraglottal pressures
• this pulls back the vocal folds together

Question 5

Poll question: During the process of voicing, what is the primary reason the vocal folds come back together after being blown apart by the airflow.
a. muscle contraction pulls the vocal folds back together
b. vocal folds are pulled together due to the drop in pressure between tham
c. elasticity of the vocal folds naturally restores them to their original position.
d. increased subglottal pressure forces the vocal folds to close again.

Answer 5

b.
not a. Muscles need neural command and neural command is not fast enough.
Not c. there is no original position nd elasticity is not a factor.
not d. its decreased pressure.

Question 6

what are the requirements for voicing?

Answer 6

• your vocal folds have to be in the ready position.
• subglottal pressure must be 2cm H20 greater than the supraglottal pressure to get air flowing fast enough.

Question 7

out of bilabial and velar implosives which is more prevalent in the worlds lanuages

Answer 7

Bilabial - greater volume in bilabial constriction than in a velar so its easier to create more negative pressure when larynx is loweredw

Question 8

what is modal voicing

Answer 8

the regular voicing in most vowels.

Question 9

what does the voicing continuum demonstrate

Answer 9

most open vocal folds - most closed vocal folds. Voiceless, breathy modal, creaky, glottal closure.

Question 10

non modal voicing: what makes the creaky voice creaky

Answer 10

the arytenoid cartilages are tightly together and only the anterior end vibrates. called vocal fry in English.

Question 11

non modal voicing: what makes the breathy voice breathy

Answer 11

vocal folds are losser and more air gets through with each cycle.
