Using “baby talk” with infants isn’t just cute: It could help them learn to make words

A new study suggests that when parents baby talk to their infants, they might be helping them learn to produce speech.

The way we instinctively speak to babies — higher pitch, slower speed, exaggerated pronunciation — not only appeals to them, but likely helps them learn to understand what we’re saying. New research from the University of Florida suggests that baby talk can have another, previously unknown benefit: helping babies learn to produce their own speech. By mimicking the sound of a smaller vocal tract, the researchers think, we’re cluing babies in to how the words should sound coming out of their own mouths.

“It seems to stimulate motor production of speech, not just the perception of speech,” said Matthew Masapollo, Ph.D., an assistant professor in UF’s Department of Speech, Language, and Hearing Sciences and director of the UF Laboratory for the Study of Cognition, Action, and Perception of Speech in the College of Public Health and Health Professions. “It’s not just goo-goo ga-ga.”

In the study, the researchers changed the frequency of sounds to mimic either an infant or adult vocal tract, then tested how infants reacted. Six- to eight-month-old babies “displayed a robust and distinct preference for speech with resonances specifying a vocal tract that is similar in size and length to their own,” they wrote.
