Abstract

The received wisdom when it comes to early vocalisations and pre-language in babies with Down syndrome, is that they are similar to their typically developing peers, despite being somewhat delayed. A seminal paper by Smith and Oller (1981) concluded that “substantial similarities” were found between 10 infants with Down syndrome and nine typically developing infants in terms of the emergence of canonical re-duplicated babbling and trends in consonant and vowel development over time. A review by Stoel- Gammon (1997), despite giving evidence of some differences, concluded that developmental patterns of babble were within the normal range. However, many parents of babies with Down syndrome comment that their babble sounds different to that of the other children in the same family. Also, the transition from babble to intelligible speech is very delayed. Why should this be? Our study is designed to give some qualitative data on the babble of infants with Down syndrome. What sort of vocalisations are they making and what parameters are parents identifying when they hear a meaningful utterance?
