Vocal Tract Resonance Notes part 2
For back vowels, more rounding =
More constriction = lower formants
/u/ has the most lip rounding, and lowest overall formants of all back vowels
Created by the position of the tongue in relation to the
Vocal Tract Resonance Notes part 1
Characteristics of the vocal tract
-Open at 1 end, closed at the other (Quarter Wave Resonator)
-Series of connected, air filled tubes
-Each container is a band pass filter, each has its own Resonant Freq
Speech Notes part 2
What is the problem with the Acoustic Invariance Theory?
Even though it is relatively true, there is a problem point with this theory.
-Sometimes phonemes are produced with variation on them and we are still
able to perceive it correct

How does the vocal tract resonance change?
It changes based on the different movement of articulators that change the
shape of the vocal tract
The main components of the
