COMD 5070 FINAL PREP EXAM AND ANSWERS
A coordinative structure is - answer-a group of muscles that works together to achieve an
articulatory goal
A formant is most like which type of filter? - answer-band pass
A low pass filter - answer-blocks high frequencies
A power spectrum is a type of - answer-frequency domain plot
A reduced vowel quality applies to - answer-central vowels
A simple, low tech tool for a doctor to view a person's larynx is - answer-a laryngeal mirror
A single vertical line on a line spectrum would represent - answer-a sine wave
a table of numbers could fully represent - answer-a digital signal
A typical range of variation for fundamental frequency (F0) during reading passages would be
about - answer-3 semitones
aliasing during digital recording means that - answer-a sinusoid is transformed into a different
frequency
an 8-bit A/D system has how many quantization levels? - answer-256
an analog signal (e.g. from a microphone) - answer-is continuous in amplitude
is continuous in time
both of the above
An electroglottograph reveals details of voicing by - answer-passing a current across the vocal
folds
anti-aliasing filtering - answer-removes frequency components above the Nyquist frequency
As a person raises their fundamental frequency from low to high, how would a spectrogram of
their vowel phonation change? - answer-vertical striations on a wide-band spectrogram would
get closer together
As sound travels through air, it does so as a - answer-longitudinal pressure wave
As the voice increases in intensity - answer-SQ increases and OQ decreases
Based on the equal loudness curves figure (2-18, p33), a 100 Hz tone would need to be
approximately how many dB in intensity to sound equally loud to a 1000 Hz tone at 40 dB? -
answer-53 dB
Clear speech typically includes - answer-increased fundamental frequency variability
, Direct measurement of lung pressure is achieved by - answer-puncturing the neck with a needle
below the vocal folds
During the closure of a voiced stop, vocal fold vibration may cease because - answer-
supraglottal pressure rises to equal subglottal pressure
During the transition from a stop to a vowel - answer-F1 rises
Electropalatography is useful for revealing - answer-tongue contact patterns for complex
consonants
Evidence to support the view that acoustic targets are the main control variables for speech
comes from - answer-distortions in the speech of people with hearing impairment
For a stop to be perceived as voiceless, the VOT would generally be - answer-40 to 100 ms
For both front and back vowels, F1 - answer-varies inversely with vowel height
How does the EMMA articulatory tracking system work? - answer-receiver coils on the
articulators pick up electromagnetic signals
If you lengthen the vocal tract - answer-the formants will decrease in frequency
In learning about vowel formants, it is a common misperception that - answer-formants are
located at specific physical points in the vocal tract
In stroboscopy of the vocal folds, slow motion movement is - answer-simulated by having
sequential images taken successively later across several vibratory cycles
In the production of diphthongs, the vowel movement is generally - answer-from low/mid to
higher
from tense to lax
from long to short
all of the above
In the research literature, the voice range profile (VRP) has also been called the - answer-
phonogram
phonetogram
F0-SPL profile
all of the above
In vocal modulation, the frequency changes over time are - answer-slow and rhythmic
Intensity can be defined as - answer-power per unit area
It is best to compute jitter in a voice - answer-during steady state phonation
Loudness is best measured by - answer-having a listener make a perceptual judgment
