The acoustic theory of vowel production relies on two assumptions
linearity and time invariance
If you lengthen the vocal tract
the formants will decrease in frequency
A reduced vowel quality applies to
central vowels
For both front and back vowels, F1
varies inversely with vowel height
In learning about vowel formants, it is a common misperception that
formants are located at specific physical points in the vocal tract
In the production of diphthongs, the vowel movement is generally
from low/mid to higher
from tense to lax
from long to short
Skilled singers can achieve formant tuning by
altering vocal tract posture
A formant is most like which type of filter?
band pass
As a person raises their fundamental frequency from low to high, how would a spectrogram of their vowel phonation change?
vertical striations on a wide-band spectrogram would get closer together
Volumetric imaging entails
reconstructing a 3-dimensional image of the vocal tract from CT or MRI
