比较了患有和不患有唐氏综合症的婴儿的标准牙牙学语。患有唐氏综合症的婴儿和正常发育的婴儿在生命的第一年就开始出现标准的牙牙学语，但患有唐氏综合症的婴儿在两个月后才开始。一旦开始，他们的标准牙牙学语就不如正常发育的婴儿那么稳定。患有唐氏综合症的婴儿开始牙牙学语的年龄与他们 27 个月大时的早期社交沟通量表得分相关。这项研究的结果表明，唐氏综合症影响出生后第一年的声音发育，并且早期声音发育可能与运动和认知因素相结合，与唐氏综合症儿童后来的社交和沟通功能相关。
Canonical babbling of infants with and without Down syndrome was compared. Infants with Down syndrome and typically developing infants began canonical babbling in the first year of life, but the infants with Down syndrome began 2 months later. Once begun, their canonical babbling was less stable than that of typically developing infants. Age at onset of canonical babbling for the infants with Down syndrome was correlated with their scores at 27 months of age on the Early Social-Communication Scales. The results of this study suggest that Down syndrome influences vocal development in the first year of life and that early vocal development is related, possibly in combination with motoric and cognitive factors, to later social and communicative functioning of children with Down syndrome.
