key questions Flashcards
What three components must every sound production system have?
energy (lungs also called pulmonic)
sound source (vocal FOLDS)
filters (mouth, teeth, tongue, nose, ect)
What are the two types of pulmonic sounds and how are they produced?
out flow (egressive)
in flow (ingressive)
What is phonetics?
sub field of linguistics
examines sounds and sound inventories
What units represent speech?

syllable
feature

segments
what is a segment

vowels
constants
glides/semivowels/semi constants
How is sound produced in the larynx?
air passes through. vocal folds located here
vocal folds vibrate/move/ stay still to create sound
What is the glottis?
the space between the vocal folds where air flows.
4 states
What is the shape of the vocal folds for the four different states of the glottis?
1 voiced- open, close together causing vibrating
2 voiceless- open not vibrating not close
3whisper- voiceless, front of vocal folds closed, back are apart at same time
4 murmur- breathy voice, voiced but vocal folds more relaxed than in voiced
What are the three areas of the body that are used to modify sound?
oral cavity, nasal cavity, larynx
What are the two major classes of sounds?
constants and vowels
How do vowels differ from consonants in terms of articulation?
vowels are open and have little to no obstruction in the oral and vocal tract, constants have obstruction in oral tract
define a vowel
sonorous, syllabic sounds, more open vocal tract
define the term ‘syllabic’
syllable is peak of the sonority surrounded by less sonorous segments. usually a vowel.
define a constant
less sonoous than vowel, vocal tract is obstructed in some way to form it.
