The acquisition process of consonants in early childhood: Focusing on segmental correspondences between the child and adult languages

The aim of this study is to reveal the order and the age of mastery of phonemic contrast in consonantal sounds of Korean. For this purpose, we made an observation of the correspondences between the sounds produced by children of 12-36 months and the target sounds produced by adults. The provisional order and the age of contrast acquisition shown from the results of this study are as follows: 1) The differential production of consonants by the place of articulation is accomplished before 18 month. 2) As for the differential production of consonants by the manner of articulation, the contrast between the nasal and oral sounds is first established in the age of 24-30 months, and the contrast between the stop and the affricate is not accomplished until 36 months. The liquid and the fricative are not produced or rarely produced before 36 months. 3) As for the differential production of consonants by phonation type, the contrast between the tense and the non-tense is established in the 30-36 months, and subsequently the contrast between the plain and the aspirated is established around the age of 36 months.
