Profiling the phonological abilities of 2-year-olds: a longitudinal investigation

Abstract

The purpose of this report is to profile the changes in phonological skills produced by a group of 12 children between the ages of 24 and 36 months. Conversational samples obtained from the subjects at 3-month intervals were analysed for phonetic content, prevalent error patterns, syllable shapes and consonant clusters produced. In addition, per cent of consonants correct (PCC) and mean length of utterance (MLU) information is also reported.
