vocal modulation - rhythmic changes that are predictable in fundamental frequency and in
amplitude in the voice; gradual increases and decreases that occur over the course of many glottal cycles
Sampling rate - the frequency with which numbers are stored or written down to represent the
analog signal that you're sampling.
perceptual normalization - When a listener simplifies the processing of the speech signal to
smooth out superfluous variability, it is called
categorical perception - One type of quantal perception that occurs as we listen to speech is called
syllable components are presented separately, but simultaneously, to each ear - In duplex

12 - How many semitones are in one octave?
5.9% - There are ________ more semitones in the octave before the last
the higher the sampling rate, the better the playback quality - How does sampling rate relate to
playback quality?
Nyquist frequency - The highest frequency the can be reproduced- or the highest sampling rate
high pass filter - allows high frequencies through and holds back lower frequencies
low pass filter - blocks high frequencies. The best way to avoid aliasing during a digital recording.
band pass filter - allows a band of frequencies though and holds back both higher and lower
frequencies
band reject filter - holds back a band of frequencies and allows both higher and lower frequencies
through
frequency domain - a line spectrum shows the frequency components of a period sound
