the higher the frequency the higher the sound

Answer 5

true when it comes to pitch

frequency and amplitude are dependant

Answer 7

false. independent. not effected by one another

when the amplitude is doubled the loud ness is quadrupled

Answer 8

true

Question 9

when the frequency is doubled the pitch is quadrupled

Answer 9

false. they are directly proportional

voiced fricatives are periodic sounds

Answer 10

true flow like water.

Question 11

F0 is the zeroth formant, dince f1 is the first formant

Answer 11

f

Answer 12

t

Question 13

if the first formant is 300 hz the second formant is 600hz

Answer 13

false. no relation between f1 f2 and fundamental frequency

Question 14

the vocal folds decide the harmonics, and the vocal tract decides the formants

Answer 14

true

in the source-filter theory of speech production, the source and the filter are independent

Answer 15

true

Question 16

when the pitch is tshe same creaky voice is louder

Answer 16

true

Question 17

longer the vocal tract the higher the frequencies

Answer 17

false

Question 18

rounding lips results in decreased formants

Answer 18

true

Answer 20

trues

Question 21

formant frequencies are evenly spaced

Answer 21

falseeee

Question 22

breathy slope

Answer 22

steeper slope less vocal effort

Question 23

creaky voice

Answer 23

less steep slope.

Question 24

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

Answer 24

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

is praat a spectragraph

Answer 28

yes

Question 29

is praat a spectogram

Answer 29

false, praat creates spectragrams and spectragraphs?

Question 30

a spectrogram is a set of spectra

Answer 30

trueA??

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

Answer 31

false its frequency

Question 32

the horizontal x-axis of a spectrogram is time

Answer 32

true

Question 33

both the waveform and the spectrogram are time-domain representations

Answer 33

false sine waves don't change frequency over time.

Question 34

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

Answer 34

false theres three not ALL speech sounds

Question 35

nasal stops are transient waves

Answer 35

false periodic complex

Question 36

only vowels can be represented by a spectra

Answer 36

false i think they all can

Question 37

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

Answer 37

truenot sure

Question 38

the essential information abbout a consonant appears in its constriction interval

Answer 38

true not sure

Question 39

voiceless consonants have a shorter constriction intervals than tehir voiced counterparts

Answer 39

true

Question 40

stop gaps are always complete silence

Answer 40

false

Question 41

vot means beginning of the release burst

Answer 41

it cna happen before too false

Question 42

a negative vot means a voiceless stop

Answer 42

false negative is short more likely to be indicative of voicing

Question 43

obstruents include stops, fricatives and affricates

Answer 43

t obstruents and stops are affricates are stops and fricatives

Answer 44

true?

Question 45

nasals are approximants

Answer 45

false

Question 46

not all sonorant sounds are approximants

Answer 46

t not all are approximants ALL again fuck
