Three cues for identifying diphongs on spectrogram
onglide, offglide and rate of change
Wideband spectrograms allow you to see multiple
harmonics at once
Difference between wideband spectrogram and narrow band spectrogram
wideband provides formant frequencies and narrow band provides individual harmonic structures
VOT for voiceless stop is
50 or more m/s
VOT for voiced stop is
35 m/s or less
F1 formant transition tells you
manner
F2 formant transition tells you
place
After voiced stops F0 remains
flat
After voiceless stops F0 is
elevated momentarily
Acoustic cue of fricative
high energy/frequency noise
What is the clinical use of narrowband spectrograms?
Voice evaluation
VOT definition
time from burst to engagement of vocal folds
Why is there a formant shift?
Vocal tract is shaped for a certain vowel
Why is VOT important?
Tells listener if sound if voiced or voiceless
What do formant frequencies represent?
Resonant freuqnecies to identify vowel produced
