neither invariant nor linear - correct answer...✔✔The speech signal is
perceptual normalization - correct answer...✔✔When a listener simplifies the
processing of the speech signal to smooth out superfluous variability, it is called
categorical perception - correct answer...✔✔One type of quantal perception that occurs
as we listen to speech is called
syllable components are presented separately, but simultaneously, to each ear - correct
answer...✔✔In duplex perception:
the place and/or manner of articulation is perceived to change - correct answer...✔✔In
the McGurk effect:
using contextual, linguistic, and cognitive cues - correct answer...✔✔Top-down
processing in the perception of speech involves
motor theory - correct answer...✔✔Which speech perception theory has been criticized
as being so vague that it is more of a philosophy than a theory or model?
perceptual magnets - correct answer...✔✔enhance differences between distinct
phonemes
Cohort theory - correct answer...✔✔based on similarity of acoustic features of the
beginning of words
dominant language exposure gradually decreases discrimination of non-native speech
features - correct answer...✔✔research with infants has shown that
a refinement of everyday thinking - correct answer...✔✔What is science?
empirical, deterministic, predictive, parsimonious - correct answer...✔✔What are the 4
features of the scientific method?
semitone - correct answer...✔✔A nonlinear increase in frequency as you go from low to
high
12 - correct answer...✔✔How many semitones are in one octave?
AGRADESOLUTIONS
, 5.9% - correct answer...✔✔There are ________ more semitones in the octave before
the last
Sampling rate - correct answer...✔✔the frequency with which numbers are stored or
written down to represent the analog signal that you're sampling.
the higher the sampling rate, the better the playback quality - correct answer...✔✔How
does sampling rate relate to playback quality?
Nyquist frequency - correct answer...✔✔The highest frequency the can be reproduced-
or the highest sampling rate
high pass filter - correct answer...✔✔allows high frequencies through and holds back
lower frequencies
low pass filter - correct answer...✔✔blocks high frequencies. The best way to avoid
aliasing during a digital recording.
band pass filter - correct answer...✔✔allows a band of frequencies though and holds
back both higher and lower frequencies
band reject filter - correct answer...✔✔holds back a band of frequencies and allows
both higher and lower frequencies through
frequency domain - correct answer...✔✔a line spectrum shows the frequency
components of a period sound
time domain - correct answer...✔✔a waveform represents sound directly, air pressure
changes over time
FFT spectrum - correct answer...✔✔-clearly shows harmonic energy
-each peak is a harmonic
-less clear at showing formants
-more revealing of source
LPC Spectrum - correct answer...✔✔-shows spectral envelope
-good at revealing formants
-does not show harmonics
-more revealing of filter
