Researchers at the University of York and Aarhus University explored the similarities in baby talk across 36 languages. The study is published in the journal Nature Human Behaviour.
The research team wanted to understand whether baby talk or infant-directed speech (IDS) has universal qualities in different languages. It used a meta-analytic method to examine previous studies about IDS and its role in child development. The analysis took into consideration factors like pitch, melody, articulation of vowel sounds, etc.
The results revealed that baby talk has universal qualities across all languages. It was also found that how caregivers talk to young infants changes as the child’s grasp of language and speech increases.
Most features of infant-directed speech gradually become more similar to adult speech style, but the high pitch melodic sounds and exaggerated vowels continue into early life.
One of the lead researchers, Professor Riccardo Fusaroli, elaborated: “These results really highlight the interactive nature of this speech style, with caregivers providing dynamic and tailored feedback to their children’s vocalizations and reacting to infants’ changing developmental needs.”
