ASLP 3030: Final Exam Questions and
Answers 100% Solved 2024/2025 Update
What is a complex waveform? - ✔✔a wave that has a series of multiple
sine waves and contains the fundamental frequency
How do speakers increase their perceived loudness? - ✔✔-drive more sub
glottal pressure
-more forceful vocal fold collisions
-higher oral pressure
-consonant burst release stronger
What is the main thing that distinguishes a digital signal from an analog
signal? - ✔✔analog sounds are continuous and can be examined in every
little detail and digital signals are discrete
What is sampling rate? - ✔✔the number of snapshots (amplitude values)
that are taken of the wave
What is quantization? - ✔✔the process by which you measure the signal
amplitude and assign it a digital number
What is a spectrum and how is it different from a spectrogram? - ✔✔A
Spectrum is a snapshot in time whereas a spectrogram is speech over time
, What is Fourier analysis/Fourier transform? - ✔✔a way to analyze complex
signals and splitting them into a series of different components
What does the spectrum of a person's voice look like? - ✔✔a variety of
pointy peaks, peaks that occur at regularly spaced intervals, and shape is
more complicated
What are jitter and shimmer? - ✔✔Jitter = random cycle-to-cylce changes
in duration
Shimmer = random cycle-to-cycle changes in amplitude
Why is it challenging to see the movement of the vocal folds using standard
video/filming techniques? - ✔✔-the vocal folds more quickly
-movements are blurred to the eye
What is the technique involving strobe lights that you can use to see the
movements in slow-motion? How does that work? - ✔✔-Stroboscopy
-light flashes on the vocal folds and illuminates by taking a snapshot and
pastes them together in a succession
In what speech sounds is intra oral pressure higher than atmospheric
pressure? In what speech sounds is it roughly equal? - ✔✔higher for stop
consonants, equal for vowels
