1. what is the source for vowel sounds pressure wave generated by
periodic vocal fold vibration
2. what determines frequency of the source periodic vocal fold vibration
spectrum
3. how does the source sound change constriction along the path
of the vocal tract acting as a
filter / resonator
INDEPENDENT from each
4. the source and filter are...
other
5. perturbation theory understanding the
relationship between vocal
tract configurations and
formant frequencies (any
constriction in the VT
affects all resonant
frequencies of the tube, a
lawful connection between
articulatory configuration
and VT formant
frequencies)
6. Fourier analysis a mathematical approach
that decomposes a
complex time domain
function into a set of its
simple functions
7. T / F: formant frequencies of vowels are de- FALSE - formants are
determined by contermined by the rate at which vocal folds
figuration of the vocal tract, PITCH is de-
vibrate termined by VF vibration
, 8. across speaker variability gender, dialect, language, age, etc
9. is FF sufficient enough to identify the intend- NO! variation in formants
is vast ed vowel?
10. within speaker variability speaking rate, syllable stress, speaking
style, phonetic context
11. comparative acoustic phonetics seeks to determine if the same IPA
sym-
bol is actually the same
sound across languages
12. Does the use of the same IPA mean its pho- NO! netic / acoustic
characteristics are the same?
13. T / F: the acoustic characteristics of Korean FALSE
/u/ are likely to be very similar to those of American
English /u/ because they are both transcribed with
the same IPA symbol
14. articulatory undershoot movement of the vowel acoustic space in-
wards towards schwa
because the speaker does
not have sufficient time to
reach the target position.
However, vowels are still
intelligible to the listener
