COMD 5070 final prep
A coordinative structure is - correct answer-a group of muscles that works together to
achieve an articulatory goal
A formant is most like which type of filter? - correct answer-band pass
A low pass filter - correct answer-blocks high frequencies
A power spectrum is a type of - correct answer-frequency domain plot
A reduced vowel quality applies to - correct answer-central vowels
A simple, low tech tool for a doctor to view a person's larynx is - correct answer-a laryngeal
mirror
A single vertical line on a line spectrum would represent - correct answer-a sine wave
a table of numbers could fully represent - correct answer-a digital signal
A typical range of variation for fundamental frequency (F0) during reading passages would
be about - correct answer-3 semitones
aliasing during digital recording means that - correct answer-a sinusoid is transformed into a
different frequency
an 8-bit A/D system has how many quantization levels? - correct answer-256
an analog signal (e.g. from a microphone) - correct answer-is continuous in amplitude
is continuous in time
both of the above
An electroglottograph reveals details of voicing by - correct answer-passing a current across
the vocal folds
anti-aliasing filtering - correct 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? - correct answer-vertical striations on a wide-band
spectrogram would get closer together
As sound travels through air, it does so as a - correct answer-longitudinal pressure wave
As the voice increases in intensity - correct 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? -
correct answer-53 dB
Clear speech typically includes - correct answer-increased fundamental frequency variability
Direct measurement of lung pressure is achieved by - correct answer-puncturing the neck
with a needle below the vocal folds
During the closure of a voiced stop, vocal fold vibration may cease because - correct
answer-supraglottal pressure rises to equal subglottal pressure
During the transition from a stop to a vowel - correct answer-F1 rises
Electropalatography is useful for revealing - correct answer-tongue contact patterns for
complex consonants
Evidence to support the view that acoustic targets are the main control variables for speech
comes from - correct answer-distortions in the speech of people with hearing impairment
For a stop to be perceived as voiceless, the VOT would generally be - correct answer-40 to
100 ms
For both front and back vowels, F1 - correct answer-varies inversely with vowel height
How does the EMMA articulatory tracking system work? - correct answer-receiver coils on
the articulators pick up electromagnetic signals
If you lengthen the vocal tract - correct answer-the formants will decrease in frequency
In learning about vowel formants, it is a common misperception that - correct
answer-formants are located at specific physical points in the vocal tract
In stroboscopy of the vocal folds, slow motion movement is - correct answer-simulated by
having sequential images taken successively later across several vibratory cycles
In the production of diphthongs, the vowel movement is generally - correct 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 - correct
answer-phonogram
phonetogram
F0-SPL profile
