TRUE FALSE FOR EXPERIMENTAL PHONETICS OX Flashcards
all sonorant sounds are voiced
true, vowels, nasals , liquids, glides
the opposite of sonorants are obstruents
true. sonorants voiced obstruents not voiced
there can be no sound under water
false you can its faster
sound travels slower underwater than in air
f sound travels faster
the higher the frequency the higher the sound
true when it comes to pitch
the higher the amplitude the higher/louder the sound
true but not directly
frequency and amplitude are dependant
false. independent. not effected by one another
when the amplitude is doubled the loud ness is quadrupled
true
when the frequency is doubled the pitch is quadrupled
false. they are directly proportional
voiced fricatives are periodic sounds
true flow like water.
F0 is the zeroth formant, dince f1 is the first formant
f
If the first fharmonic is 100 Hz, the second harmonic is 200Hz
t
if the first formant is 300 hz the second formant is 600hz
false. no relation between f1 f2 and fundamental frequency
the vocal folds decide the harmonics, and the vocal tract decides the formants
true
in the source-filter theory of speech production, the source and the filter are independent
true
when the pitch is tshe same creaky voice is louder
true
longer the vocal tract the higher the frequencies
false
rounding lips results in decreased formants
true
harmonics and formants are independent to each other
t
harmonic frequencies are evenly spaced
trues
formant frequencies are evenly spaced
falseeee
breathy slope
steeper slope less vocal effort
creaky voice
less steep slope.
formant frequencies are equally spaced when the vocal tract is not constricted at all
true. schwa. graph looks even so i guess so.
higher vowels higher f1
false low vowels have higher f1
front vowels have a higher f1
f front vowels have a higher f2
front vowels have a higher f2
true
is praat a spectragraph
yes
is praat a spectogram
false, praat creates spectragrams and spectragraphs?
a spectrogram is a set of spectra
trueA??
the vertical y-axis of a spectro gram is the amplitude of sound
false its frequency
the horizontal x-axis of a spectrogram is time
true
both the waveform and the spectrogram are time-domain representations
false sine waves don’t change frequency over time.
the source of all speech sounds is the vbration of the vocal folds
false theres three not ALL speech sounds
nasal stops are transient waves
false periodic complex
only vowels can be represented by a spectra
false i think they all can
the articulation of a consonant corresponds to its constriction interval on a spectrogram
truenot sure
the essential information abbout a consonant appears in its constriction interval
true not sure
voiceless consonants have a shorter constriction intervals than tehir voiced counterparts
true
stop gaps are always complete silence
false
vot means beginning of the release burst
it cna happen before too false
a negative vot means a voiceless stop
false negative is short more likely to be indicative of voicing
obstruents include stops, fricatives and affricates
t obstruents and stops are affricates are stops and fricatives
approximants are sonorant consonants
true?
nasals are approximants
false
not all sonorant sounds are approximants
t not all are approximants ALL again fuck
all sonorant sounds in english are voiced
true
the opposite of sonorants are obstruents
true
0 dB means silence
false just standard
it is possible to have a negative number on the dB scale
t its just the smallest sound difference that you can detect with your humans ears.
0 Hz = means silence and no cycles
t
perception of frequency ranges more widely than intensity?
dB is condensed over a huger more wider range so false?
60 DB is twice as loud as a sound at 50 db
true, multiples of ten
60 dB 10 times greater than that of a sound at 50 dB
true multiples of ten idk
the octave sccale is relative scale while the hertz scale is an absolute scale
true
the octave is a logarithmic scale
true
