laryngeal anatomy
which laryngeal muscle causes change in pitch?
cricothyroid
this is the part of the lamina propria that is visible to us with a pearly appearance
epithelial layer
the vocal tract is also known as what?
our resonating space and/or the filter
what acoustic measurement is used to identify vowels? (hint: they are determined by tongue position)
formants
what are the steps to plosive production?
1. create occlusion
2. build up pressure
3. release occlusion
which muscle is responsible for VF vibrations?
thyroarytenoid (body of VF)
this portion of the lamina propria initiates vibration?
thryoartenoid muscle
what is the relationship between resonating space size and frequency?
larger space = lower frequency
what determines the value of F2?
space anterior to constriction
front vs back
a silent gap occurs when in a spectrogram?
before occlusion is released
which cartilage swings to adduct & abduct the VFs?
arytenoid cartilages
myoelastic theory is used to explain what?
voice as a product of muscle forces interacting, elastic recoil & airflow/pressure
which articulator shapes the vocal tract for vowel freqeuncies?
the tongue
what determines the value of F1?
pharyngeal space (space behind the constriction)
high vs. low vowel
this acoustic event appears as a vertical line of transient noise on a spectrogram
noise burst
interarytenoid
which layer of the lamina propria is made up of elastic fibers?
intermediate lamina propria
what characteristic of the vocal tract most effects resonant frequencies?
length
which vowels are maximally different?
quantile vowels /i/ (low F1 high F2) and /a/ (high F1 low F2)
what is the cutoff for the perception of voiced and voiceless plosives?
30 msec
this is the only muscle used to abduct the VFs, especially for voiceless sounds?
posterior cricoaryetnoid
what is the purpose of the deep lamina propria?
transition support structure
what does it mean when only certain ranges of waveforms pass through others lose energy?
it went through broad band filter
what is the stable relationship between F1 and F2 for specific vowels known as?
vocal tract normalization
if there are issues with the larynx how are voiceless plosives produces?
exaggerating/overaspiration
