L.O. To be able to explain the key patterns in
childrens phonological development
2
Pre-verbal stages of language acquisition

• Vegetative
• Cooing
• Babbling
• Proto-words

3
COOING
The main difference between these two stages is
the use of vowels and consonants
BABBLING
4
COOING
Babies use open-mouthed vowel sounds like oo
and ah
5
BABBLING
Babies begin to combine consonant and vowel
sounds into CVCV patterns
Reduplicated Babbling repetition of the same CV
structure
Variegated Babbling combinations of different
CV structures

Phonological Development

• Vowels are acquired before consonants
• 2 ½ years all vowel sounds but only 2 thirds
  of consonants
• 4 years all vowel sounds and nearly all
  consonants
• 6/7 years all vowel sounds and all consonants
• (The above are only general guidelines)

True e.g. p and b are easier in push and
bush than in rip and rib
True or False? Consonants are used correctly at
the beginning of words before being used
correctly at the end of words
12

• In pairs think of some words that you used to
  mispronounce when you were a child

13
ADDITION
Adding an extra vowel sound to create a CVCV
structure
14
DELETION
Leaving out the last consonant of a word, so a
word like mouse becomes mou (mow)
15
REDUPLICATION
The repetition of particular sounds and structures
16
SUBSTITUTION
One sound is swapped for another, easier sound
17
CONSONANT CLUSTER REDUCTION
Children find it difficult to produce consonant
clusters groups of 2 or more consonants so
will reduce them to smaller units
18
DELETION OF UNSTRESSED SYLLABLES
The removal of an entire unstressed syllable from
a word
19
ASSIMLIATION
A process in which substitution occurs but the
sound changes because of other sounds around it,
e.g. a sound is substituted with one that is
closer to others in the word
20
You have a selection of words. Stick them to the
definition they are an example of
