Phonological development Flashcards
What stage does phonological development occur in?
Post-telegraphic stage
What are the key points of phonological development?
- 1st year will develop control of the muscles vital to producing clear and varied speech
- In speech vowel sounds require no obstruction of air flow to create sound
- Consonants require some brief interruption to the airflow by articulators in order to create the required sound
What are dipthongs?
A sound formed by the combination of 2 vowels in a single syllable, in which the sound begins as one vowel and moves towards another
What are monophthongs?
A vowel that has a single perceived auditory quality
What are articulators?
The vocal organs placed above the larynx including the lips, teeth, tongue and hard palate that help for consonant sounds
What lends complexity to the process of phonological development?
The variety of ways in which different sounds can be made
What are the 6 manners of articulation?
1) Plosives
2) Nasals
3) Fricatives
4) Affricates
5) Approximants
6) Laterals
What are plosives?
p,b,t,k,g
- when two articulators touch each other
- the upper and lower lip held together in the production of sound
- air pressure is built up and released in a burst
What are nasals?
m,n,ng
- two articulators are touching but air is released through the nose
What are fricatives?
f,v,s,z,sh
- these involve near contact of the articulators
- air is pushed out through a small space
What are affricates?
ch,dj
- begin as plosive and end as fricative
What are approximants?
r,j,w
- produced without articulators making contact
What are laterals?
l
- produced by articulators making contact and air flowing down the sides of the tongue
Which are acquired first between vowels and consonants?
Vowels
What are the most common consonant sounds for young children acquiring English?
b,d,m,n,h
What have children acquired by the age of 2 and a half?
All of the vowels and 2/3 of the consonants
