Which of the following are true about the burst stage of a stop for the sound [k]? (Select two correct answers.)
a) The filter for the burst is the cavity from velum to the lips.
b) The source of sound is a transient caused by rapid pressure equalization.
c) Voicing at the glottis is the primary source of the burst.
d) The filter for the burst is the cavity from glottis to velum.
a) The filter for the burst is the cavity from velum to the lips.

b) A lower F1 towards the beginning of the vowel in the sound sequence [ka].
Which one of the following shows the most plausible ranking about frequency peaks of spectral energy in different stop sounds?
(e.g., A > B means A has higher frequency peak of spectral energy. [c] is a palatal stop.)
a) [c > t > k]
b) [t > c > k]
c) [t & c > k]
d) [t < c < k]
b) [t > c > k]
What is the key characteristic of the uvular nasal [N] in tube modeling?
a) [N] involves a dual-tube model, one for the oral cavity and one for the nasal cavity.
b) [N] can be modeled as a tube closed at both ends, which is also true for [ə].
c) [N] involves a dual-tube model with the back cavity as a Helmholtz resonator
d) [N] can be modeled as a single-tube with one open end.
d) [N] can be modeled as a single-tube with one open end.
Which of the following act as the largest contributor to lower the resonance frequencies of the uvular nasal [N], compared to the vowel [ə]?
a) [N] has a shorter tube length and lip constriction.
b) [N] has a longer tube length and nostril constriction.
c) [N] has a shorter tube length and smaller opening.
d) both have equal tube length but [N] involves a nostril constriction.
b) [N] has a longer tube length and nostril constriction.
What is true about the acoustic properties of nasals sounds?
a) The filter for nasals includes the nasal passage which, in turn, affects the resonance properties.
b) Nasals rely on the oral cavity for their source of sound.
c) Nasals use the same filters as the vowel [ə].
d) The source of nasals is entirely different from vowels.
a) The filter for nasals includes the nasal passage which, in turn, affects the resonance properties.
