Chapter 5 Flashcards
sound perception
the ability to distinguish sounds
International phonetic alphabet
EACH SYMBOL REPRESENTS ONE SOUND
phonology
the study of the sound system of a language
phoneme
a class of speech sounds and the smallest unit of sound that can affect meaning.
allophone
varied productions of an individual phoneme.
vowels
involve vocal fold vibrations
open oral tract
what shapes the vocal tract?
tongue
jaw movement
lips
diphthong
A combination of vowels that come together to make one sound.
consonants
produced by restricting the oral cavity
syllable
combination of a vowel and a consonant
how are consonants classified?
manner, place, and voicing
Manner of articulation
the degree or type of constriction
Place of articulation
describes the location of constriction
voicing
presence or absence of vocal fold vibrations in the production of consonants
manners of articulation
stops, fricatives, affricates, glides, liquids, nasals
stop-plosives
produced by completely stopping the airflow and then releasing it.
what are the 6 stop-plosives
P, B, T,D,K,G
Fricatives
the air is forced through a constricted oral cavity
affricates
a combination of strops and fricatives
example chair, jump
glides
the shapes of the articulators change gradually
W and J
liquids (semivowels)
The oral cavity is restricted the least.R and L
nasals
nasal resonance is added by keeping teh velopharyngeal port open N,M,nj
7 categories of place of articulation
bilabial, labiodental, linguadental, lingua-alveolars, palatals, linguavelar, glottal
bilabial sounds
produced primarily by the two ips
labiodental sounds
produced by teeth and lips
F, V
linguadental sounds
produced by the tongue which makes contact with the upper teeth
lingua-alveolar sounds
produced by raising the tip of the tongue to make contact with the alveolar ridge
N, T, D, S ,Z
linguapalatal sounds
produced by the tongue which comes in contact with the hard palate
linguavelar sounds
produced by back of tonguewhich raises up to make contact with the velum
nj, k, g
glottal sounds
are produced by the frictions noise resulting from air passing through open vocal folds.
cooing
vowel sounds start at 3 months old
babbling
combinations of consonants and vowels start at 5-7 months
cross sectional method
speech of children at different age levels is established norm
longitudinal method
only one child or a few children are observed for an extended period of time to understand the process of learning
In learning speech sounds, children simplify them, such simplifications of the adult model of correct articulations are called ________
phonological processes
vowels are acquired before consonants. True or false
Trues
nasal sounds are acquired the _______ mastered between ______ and _____
earliest
3 and 4
______ sounds are mastered before fricatives
stop
stop sounds are mastered between ____ and ____
3 and 4.5
glides are mastered before _______
fricatives
Liquids are mastered relatively late between ____ and ____ yrs old
3 and 5 yrs old
