ACOUSTICS OF SPEECH AND HEARING | QUESTIONS
AND VERIFIED ANSWERS | 100% CORRECT | GRADE
A - UTAH
simplifies, large, complex .....ANSWER.....One reason why the
study of speech production addresses the subsystems separately,
and in sequential order, is this approach ____________ a
________ and ________ topic.
distortions, hearing impairment .....ANSWER.....Evidence to
support the view that acoustic targets are the main variables for
speech comes from _________ in the speech of people with
___________.
do not agree, one .....ANSWER.....The most basic unit of analysis
for speech motor control is: Scientists _________ on _________
single unit of measurement for control.
,Page 2 of 116
repeating, differences, articular .....ANSWER.....Motor
equivalence in speech motor control means that ___________ an
utterance more than once may involve subtle _________ in
__________ movements.
increased, variability .....ANSWER.....Clear speech typically
includes __________ fundamental frequency ________.
invariant, linear .....ANSWER.....The speech signal is neither
________ nor ________.
categorical perception .....ANSWER.....One type of quantal
perception that occurs as we listen to speech is called
__________.
place, manner, change .....ANSWER.....In the McGurk effect, the
__________ and/or _________ of articulation is perceived to
________.
,Page 3 of 116
contextual, linguistic, cognitive .....ANSWER.....Top-down
processing in the perception of speech involves using _________,
________, and _________ cues.
differences, phonemes .....ANSWER.....Perceptual magnets
enhance ___________ between distinct __________.
dominant, decreases, non native .....ANSWER.....Research with
infants has shown that _________ language exposure gradually
_______ discrimination of ____________ speech features.
empirical, deterministic, predictive, parsimonious .....ANSWER.....4
features of the scientific method.
empirical .....ANSWER.....Based on data.
deterministic .....ANSWER.....Obeys physical laws.
predictive .....ANSWER.....If you do this... then that will happen.
parsimonious .....ANSWER.....Use the simplest explanation
possible.

increase .....ANSWER.....Difference Limens ________ with stimulus
frequency.
semitone .....ANSWER.....Each __________ is a nonlinear step
Each step upward is bigger than the last (about 5.9% higher
frequency than the one before it).
When we're at the low end of the pitch range, we can hear
differences between frequencies that are really rather small—
just a couple of Hz apart. But as we get to the higher end, our
difference limens are greater, and so the increasing size in Hz of
each semitone step as we go up actually matches our auditory
perceptual abilities quite nicely.
higher .....ANSWER.....__________ frequency sounds must differ
more to be heard as different in pitch
12 .....ANSWER....._______ semitones in one octave
