What is vowel normalization?
Using methods/techniques to account for variability in speakers
Normalization aims to make vowel comparisons ________ and _________
consistent; reliable
What measure do we use to make vowel normalization?
Z-scores
Name 4 goals of vowel normalizations
- Take out physiological variation caused by MOUTH size.
- Preserve sociolinguistic diffs in vowel QUALITY
- Preserve PHON. distinctions among vowels
- Model COGnitive processes in vowel normalization
Name the 4 vowel normalization techniques?
- Vowel-intrinsic method
- Vowel-extrinsic method
- Speaker intrinsic method
- Speaker extrinsic method
Vowel norm. - vowel intrinsic method (e.g.)
- using info. from a SINGLE vowel token - 1 formant in 1 vowel
- F frequency adjustments : adjusting F values based on average values for similar speakers
Vowel norm. - vowel extrinsic method (e.g.)
- Comparing F values across diff. vowels by the SAME individual - 1+ formants in 1+ vowels
- Grand mean normalization : normalizing vowels using a GRAND mean calculated from all vowels spoken by the person
Vowel norm. - speaker intrinsic method (e.g.)
normalize based on data from a single speaker’s vowels
- Individual speaker baseline : making a baseline for formant freqs. for a SINGLE speaker
Vowel norm. - speaker extrinsic method (e.g.)
take data from a MULTIPLE speaker’s vowels
- Mean adjustment method : normalizing using mean values derived from a group of speakers
Hawaiian is known for what kind of stops?
Voiceless
The acoustic cues of stops
- Closure duration
- Prevoicing and aspiration
- VOT
- Formant transition
Pressure becomes _______ in stops at what point?
bigger; Between a complete-closure of the airflow (velar port is closed) and when pressure grows and RELEASES the STOP
________ vibrations, and ______ open vocal _____ are additional gestures that helps to produce different TYPES of stops
vocal fold; wide; folds
What kinds of stop exist
voiced and voiceless
Air pressure = _____
amplitude
True or F : it IS useful to use absolute amplitude
F - relative amplitude is better to use
VOT is longer in both __________ and ____________ stops
aspirated; voiceless
T or F : VOT is NEGATIVE in voiced stops like [b, g]
T
What is and what does a voiced bar do?
A voiced bar is at the BOTTOM of the spectrogram, representing pre-voicing, before the vowel, and is used to distinguish contrasts
Vocal pulses in spectrograms =
full cycles
Which set contains sounds that are all likely to have a negative VOT?
A. [b, d, g]
B. [p, b, m]
C. [p, t, k]
A. [b, d, g]
What can formant transitions show us?
Give cues of PLACE of articulation
Give examples of formant transitions
- LOWERING of ALL Fs by bilabial stops
- Dentals RAISE F2
- Velars bring F2 and F3 nearer to eachother
What is the ‘velar’ pinch
Shown in the spectrogram, velar sounds will ‘pinch’ F2 and F3 together (e.g. GAG)
