Baby talk words with repeated sounds help infants learn language

Babies find it easier to learn words with repetitive syllables rather than mixed sounds, a study suggests. Assessments of language learning in 18-month-olds suggest that children are better at grasping the names of objects with repeated syllables, over words with non-identical syllables. Researchers say the study may help explain why some words or phrases, such as ‘train’ and ‘good night’, have given rise to versions with repeated syllables, such as choo-choo and night-night.
