Emerging Phonetic-Phonological Skills in Three Children with Down Syndrome: A Longitudinal Study

This study was structured to provide a longitudinal analysis of the emerging phonetic-phonological systems of three Down Syndrome children in the first fifty word stage of development. The three children, who at the onset of the investigation were between the ages of 3;0 and 3;2, were followed for a total of 12 months. At the beginning of the study all children had at least one but fewer than 12 spontaneous words. Play sessions which were audio-taped and simultaneously transcribed provided the data for analysis. All identifiable words were analyzed according to onset, nucleus, and coda sounds as well as syllable structures.
   In addition, phonemic oppositions were examined to see how the children were signaling meaningful contrasts. Over the 12 month timeframe both group similarities as well as individual variations emerged in all categories analyzed. These results are examined in detail.
