Question 7

Are diphthongs periodic, aperiodic or both?

Answer 7

Periodic

Question 8

Relative timing of stop releases and the initial of phonation.

Answer 8

Voice onset time

Question 9

True or false: “The source-filter account of consonsoant production (i.e., tube model) can also be applied to examining resonanting frequencies such as fricatives and oral/nasal stops. “

Answer 9

True

Question 10

True or false: Vowels, glides, liquids and nasals are all examples of resonant speech sounds due to how the various configurations of the vocal tract generate different combinations of resonant frequencies for each sound.”

Answer 10

True

Question 11

True or false: “While fricatives are described as the abrupt and brief halting of airflow, oral stops are described as continuous but turbulent airflow through an constricted channel in the supralarygeal system.”

Answer 11

False; oral stops are brief halting of airflow

Question 12

True or false: “The source-filter account of consonsoant production (i.e., tube model) can also be applied to examining resonanting frequencies such as fricatives and oral/nasal stops. “

Answer 12

True

Question 13

“In terms of the source-filter theory and the tube model, nasals differ from other sound classes (e.g.,vowels, glides, fricatives and oral stops) for which of the following reasons?”

Answer 13

Longer and larger tube

Question 14

True or false: “A plosive sound is one where air flow in the superlargeal system is completely blocked for a brief period of time, which then the release of the bulit-up air pressure causes an explosive and transient airburst. “

Answer 14

True

Question 15

True or false: “The vocal folds can be used to generate only periodic, and never aperiodic, sources of sound.”

Answer 15

False

Question 16

Constriction of the vocal tract near a point of maximum PRESSURE _____ the formant frequency

Answer 16

Increases

Question 17

Constriction of the vocal tract near a point of maximum VELOCITY _____ the formant frequency
