The preference for repeated infant vowel sounds seems to kick in as early as four months, before infants are babbling “goo goo gaa gaa” themselves, say Prof. Linda Polka of McGill’s School of Communication Disorders and her team in the journal Developmental Science.
By gazing at the screen, the babies controlled how long they heard a series of repeated “eee” vowel sounds from a synthesizer. The setup allowed scientists to control the pitch and emphasize various frequencies.
On YouTube, baby Camille smiles when she hears an infant and moves her mouth more.
Others, like baby Ethan, tried to vocalize “ee” when he heard an infant sound played for CBC News at the lab. Still others simply grinned with delight.
“What’s important to me is what role does that play in their development? How is it helping them? And what happens to a child who for some reason can’t process that kind of signal because they have a hearing loss, for example. Or babies who aren’t engaging or interested in their own voice or other baby voices. Is there something there that we should pay attention to that we could use to help those children?”
In the meantime, parents’ intuitive knowledge to use a high, infant-like voice to speak to babies is “right on,” Polka said.
At a Wholeplay class in Toronto, Tracey Norman did a hokey-pokey dance with her three-month-old, Pearl.
“She just listened to all the sounds and was so happy for the whole hour,” Norman said. “I think it was all the baby sounds.”
The Montreal team hopes to look at other vowel sounds next.
