What does a stroboscopy rely on? - ANSWER-- Animation.
- Has 30 frames/ second.
- Has to sync to fundamental frequency.
What can be viewed in real time? - ANSWER-A stroboscopy.
What is vocal perturbation? - ANSWER-- When voice is perturbed
away from perfectly periodic repetition.
- Includes jitter and shimmer.
What can vocal perturbation be caused by? - ANSWER-
Neurologic factors, airflow turbulence, or pathological tissue
change (swelling, nodules, or polyps).
What is jitter? - ANSWER-- Random changes cycle to cycle in
FREQUENCY.
,2|Page
- Co-occurs with shimmer.
What is shimmer? - ANSWER-- Random changes cycle to cycle
in AMPLITUDE.
- Co-occurs with jitter.
What sound does not change? - ANSWER-Vowels.
Why don't vowels change? - ANSWER-If you produce a vowel,
you should be able to sustain it as long as you have breath. If you
don't change the shape of your vocal tract, you'd say that sound is
time-invariant. If you look at any point in time during that vowel
prolongation that should last several seconds, it should look just
like any other point in that time frame.
What is an ordinary vowel called and why? - ANSWER--
Monophthong.
- The clear, steady state that is maintained for a period of time.
What sound changes? - ANSWER-Diphthongs.

Why do diphthongs change? - ANSWER-Because it is a
combination of two vowel sounds where the speaker's tongue
moves from one vowel position to
another while pronouncing the diphthong.
What is the source of speech? - ANSWER-Larynx.
What does changing the source of speech involve? - ANSWER--
Loudness.

What is alaryngeal speech? - ANSWER-- A change in source.
, 4|Page

becomes the sphincter.
What is the filter of speech? - ANSWER-The vocal tract.
What does change of filter of speech involve? - ANSWER-- Any
changes that occur that are not due to pitch, loudness, or quality.
- Example: Sound resonating because of how the tongue is being
constricted.
What is F1? - ANSWER-The first formant and the lowest peak.
What is F2? - ANSWER-Frequency of the second formant
What are F1 and F2 good for? - ANSWER-Identifying vowels,
even in synthetic speech.
What do higher formants do? - ANSWER-Contribute to the
naturalness of the vowel sound.
