Child Language Acquisition
2 ½ Years
Mastered vowels, and two thirds of consonants.
Will not be six or seven until totally confident with language.
Consonants are easier to say at beginning of words.
o Words with consonant endings provide some difficulty.
Children simplify language in a number of ways:
o Drop final consonants (hat > ha')
o Drop unstressed syllables (banana > nana)
o Consonant clusters (snake > nake, sleep > seep)
o Some letters are replaced for other easier letter.
o R > W
o Th > D, N, or F
o T (as in toe) > D
o P (as in pig) > B
o Similar sounds are reproduced.
o Dog > Gog.
Comprehension of phonology develops quicker than reproduction.
