ASLP 3030 Final Exam 2025 Questions
and Answers
what is a complex waveform? - --CORRECT ANSWER--a waveform that
contains multiple frequencies (ex: our voice)
how do speakers increase their perceived loudness? - --CORRECT ANSWER---
by increasing subglottal pressure
- having larger articulators movements w/ higher oral pressure
- having larger vocal folds
- excursions & more forceful vocal fold collisions
what is the main thing that distinguishes a digital signal from an analog signal? - --
CORRECT ANSWER--- digital signals are discrete snapshots over time
- analog are infinite graph: continues in time & continues amplitude, no gaps
what is sampling rate? - --CORRECT ANSWER--# of samples, snapshots, taken
per second represents an amplitude
what is quantization? - --CORRECT ANSWER--the assignment of a digital value
to describe the amplitude of a waveform

, what is a spectrum & how is it different from a spectrogram? - --CORRECT
ANSWER--- spectrum: contains all frequencies presented in a waveform--
amplitude (vertical axis) vs frequency (horizontal axis)
- spectrogram:
* x-axis goes from left to right showing time
* y-axis goes from low frequency @ bottom to high frequency @ top
*whether the trace is lighter or darker represents the intensity of signal or amount
of amplitude that is present w/ darker representing stronger.
What is Fourier analysis? - --CORRECT ANSWER--all periodic sounds are made
of a combo of sine waves varying in amplitude phases & frequencies
What is the Fourier Transform? - --CORRECT ANSWER--creates a spectrum
from time domain waveform (analyze a cake to know its ingredients)
what does spectrum of a person's voice look like? - --CORRECT ANSWER--it
will contain a peak of F0 equal spaced peak
what is jitter? - --CORRECT ANSWER--random cycle-to-cycle duration
differences
what is shimmer? - --CORRECT ANSWER--random cycle-to-cycle amplitude
differences
