Q

creaky voice

A

less steep slope.

24
Q

formant frequencies are equally spaced when the vocal tract is not constricted at all

A

true. schwa. graph looks even so i guess so.

25
Q

higher vowels higher f1

A

false low vowels have higher f1

26
Q

front vowels have a higher f1

A

f front vowels have a higher f2

27
Q

front vowels have a higher f2

A

true

28
Q

is praat a spectragraph

A

yes

29
Q

is praat a spectogram

A

false, praat creates spectragrams and spectragraphs?

30
Q

a spectrogram is a set of spectra

A

trueA??

31
Q

the vertical y-axis of a spectro gram is the amplitude of sound

A

false its frequency

32
Q

the horizontal x-axis of a spectrogram is time

A

true

33
Q

both the waveform and the spectrogram are time-domain representations

A

false sine waves don’t change frequency over time.

34
Q

the source of all speech sounds is the vbration of the vocal folds

A

false theres three not ALL speech sounds

35
Q

nasal stops are transient waves

A

false periodic complex

36
Q

only vowels can be represented by a spectra

A

false i think they all can

37
Q

the articulation of a consonant corresponds to its constriction interval on a spectrogram

A

truenot sure

38
Q

the essential information abbout a consonant appears in its constriction interval

A

true not sure

39
Q

voiceless consonants have a shorter constriction intervals than tehir voiced counterparts

A

true

40
Q

stop gaps are always complete silence

A

false

41
Q

vot means beginning of the release burst

A

it cna happen before too false

42
Q

a negative vot means a voiceless stop

A

false negative is short more likely to be indicative of voicing

43
Q

obstruents include stops, fricatives and affricates

A

t obstruents and stops are affricates are stops and fricatives

44
Q

approximants are sonorant consonants

A

true?

45
Q

nasals are approximants

A

false

46
Q

not all sonorant sounds are approximants

A

t not all are approximants ALL again fuck

47
Q

all sonorant sounds in english are voiced

A

true

48
Q

the opposite of sonorants are obstruents

A

true

49
Q

0 dB means silence

A

false just standard

50
Q

it is possible to have a negative number on the dB scale

A

t its just the smallest sound difference that you can detect with your humans ears.

51
Q

0 Hz = means silence and no cycles

A

t

52
Q

perception of frequency ranges more widely than intensity?

A

dB is condensed over a huger more wider range so false?

53
Q

60 DB is twice as loud as a sound at 50 db

A

true, multiples of ten

54
Q

60 dB 10 times greater than that of a sound at 50 dB

A

true multiples of ten idk

55
Q

the octave sccale is relative scale while the hertz scale is an absolute scale

A

true

56
Q

the octave is a logarithmic scale

A

true
