Update
Nasalized vowels are associated with: - Answer- open oral cavity and open
velopharyngeal port
Given that the oral cavity is closed for nasals, it does not contribute to the acoustics of
nasals: true or false? - Answer- False
What are the first and the second antiresonances of a closed tube with the length of .04
m (c=340 m/s). - Answer- 2125 Hz and 6375 Hz
Formant frequencies of nasals do not depend on the length of the vocal tract: true or
false? - Answer- False
Why are nasal formants more broadly tuned? - Answer- -limited radiations
-absorption inside the nasal cavities
-antiresonance
Which nasal has the largest oral cavity? - Answer- /m/
Closed tubes_________ - Answer- trap acoustic energy and generate antiresonance
Nasals can be modeled with a tube consists of pharynx, nasal cavity, oral cavity (closed
area), and a constriction at the nostrils: true or false? - Answer- True
Similar to the first nasal formant, the specifics of the higher formants do not vary with
context during speaking: true or false? - Answer- False
In addition to the first nasal formant, nasals have higher formants roughly at 1000-Hz
intervals beginning at 1000 Hz: true or false? - Answer- True
Which nasal has a first nasal formant at 250-300 Hz? - Answer- -/m/
-/n/
-/nj/ (other /n/ variations sound)
Nasals have low intensity (low amplitude) that is clearly visible in time domain
waveform: true or false? - Answer- True
, Which nasal has high frequency antiresonance? - Answer- /nj/ (other /n/ sound
variation)
Nasalized F1 amplitude is smaller than non-nasalized F1: true or false? - Answer- True
Nasalization occurs when we send sound through both the oral and nasal cavities: true
or false? - Answer- True
Which of the following vowels in the context of consonant-vowel-consonant tends to be
nasalized the least? - Answer- /bab/
Non-nasalized vowels are associated with wider formant bandwidths: true or false? -
Answer- False
Nasalization introduces a first oral resonance which may be slightly higher than non-
nasalized F1: true or false? - Answer- True
Nasalization introduces an extra resonance from the nasal tract in_____ - Answer- 300-
500 Hz
Which of the following vowels in the context of consonant-vowel-consonant tends to be
nasalized the most? - Answer- /mam/
Nasalization introduces an antiresonances located at a slightly lower frequency than the
nasal tract resonance: true or false? - Answer- False
Theoretical resonant frequencies are determined purely based speech samples: true or
false? - Answer- False
Increase in bandwidth of formants: - Answer- -muffles the vowel quality
-does not change the categories (identity of vowels)
-makes speech less intelligible
Formant frequencies are based on the spectral envelope of the speech output: true or
false? - Answer- True
In a given output spectrum, formants are necessarily aligned with the harmonics: true or
false? - Answer- False
Output spectrum is calculated directly based on the speech output: true or false? -
Answer- True
Theoretical spectrum is estimated based on modeling the vocal tract with a tube: true or
false? - Answer- True
