Exam 2

Question 1

True or false: “The quasiperiodically spaced vertical lines in a spectrogram are the acoustic result of vocal fold vibration, with each individual line reflecting a single glottal pulse. “

Answer 1

True

Question 2

True or false: The variation of F0 over several segments is referred to a F0 contour and is a classic example of a suprasegmental.

Answer 2

True

Question 3

True or false: “At the temporal measurement of a vowel, the center of the formant band, halfway between the bottom and top of the band, is taken as the formant frequency (i.e., for each formant respectively). “

Answer 3

True

Question 4

True or false: The large change in the shape of the vocal tract results in rapidly changing vocal tract resonances which are called formant transitions.

Answer 4

True

Question 5

True or false: “When an investigator identifies that the first glottal pulse of a vowel as the onset of a vocal event, this choice implies a belief that that point in time is wher ethe brain initiates a vowel and that onsets and offsets of speech segments are stored in the mind of the speaker. “

Answer 5

False

Question 6

True or false: “The acoustic result of intervals of complete vocal tract closure is called a closure interval, silent interval or stop gap. “

Answer 6

True

Question 7

True or false: Waveforms as representations of vowels are excellent at displaying formants as a function of time.

Answer 7

False

Question 8

True or false: “When scientists or clinicians talk about vowel formant frequencies in connected speech, they are usually referring to a set of measurements take at or near the temporal edges of the vowel. “

Answer 8

False

Question 9

True or false: “With the advent of the sound spectrograph, the time-varying characteristics of articulatory processes could be studied by inference from acoustic records for the first time.”

Answer 9

True

Question 10

True or false: “In the waveform representation of a vowel, the largest amplitude peaks reflect the energy produced at the instant of vocal fold closure. “
