Answer 30

f2 increases

Question 31

vocal tract modification: tongue front position

Answer 31

f2 increases

Question 32

this formant is influenced by size of pharyngeal cavity

Answer 32

f1

Question 33

Answer 33

f2

Question 34

what do horizontal lines represent on spectrum

Answer 34

vowel formants

Question 35

American English consonants are produced with

Answer 35

egressive airflow

Question 36

closure of the velopharyngeal port is achieved primarily by contraction of the

Answer 36

levator veli palatini tensor veli palatini

Question 37

the inferior, middle, and superior constrictor muscles are together referred to as the

Answer 37

pharynx

Question 38

define VOT

Answer 38

in a stop consonant its the period of time between the release of the energy and the voicing determines if it will be voiced or voiceless > 30 m/s = voiceless

Question 39

voice onset time is a critical acoustic cue for perception of

Answer 39

voiced versus voiceless stop

Question 40

antiformants

Answer 40

present when airflow is divided, such as in the /m/ and /n/

Question 41

the acoustic evidence for place of articulation for the glides is

Answer 41

the formant transition of the adjacent vowel

Question 42

for a tube closed at one end and open at the other, the tube will resonate best at a frequency that has a wavelength that is __ times the length of the tube

Answer 42

4

Question 43

3 common characteristics of deaf speech

Answer 43

They lateralize consonants with an l Nasalize their sounds Talk in lower frequencies keep tongue in mid position

Question 44

discuss how you would produce the sound /v/ relating your answer back to the source filter model.

Answer 44

/v/ is a voiced labiodental sound. the sound is coming from the larynx with the vocal folds vibrating. the vocal tract will resonate. the radiation from the lips helps create the full sound and then there is a radiated acoustic pressure wave.

Question 45

what parameters are shown on a spectrogram? what characteristics should you look for?

Answer 45

3 formants. f1 represents tongue height, f2 is tongue advancement. the darker bands are the ferments representing intensity. the more darker they are the higher the intensity. the harmonics are the areas in between the darker bands which come from the vocal tract.
