Toddlers Don’t Seem to Listen to Own Voices to Correct Speech

FRIDAY, Dec. 23 (HealthDay News) — Unlike adults and older
children, toddlers do not listen to the sound of their voice to correct
their speech, a new study finds.

Researchers had adults and 4-year-old and 2-year-old children say the
word “bed” repeatedly while simultaneously hearing themselves say the word
“bad.”

This contradiction caused the adults and 4-year-olds to change the way
they said “bed” to something more like the word “bid.” However, the
2-year-olds kept saying “bed,” the investigators found.

The findings, published online Dec. 22 in the journal Current
Biology
, suggest that toddlers use a different strategy to control
their speech.

For example, they may rely on their parents or other people to monitor
how they speak, study author Ewen MacDonald, of the Technical University
of Denmark, noted in a journal news release.

MacDonald pointed out that parents and other caregivers often repeat
back to young children what they’ve heard them say.

“As they play music, violinists will listen to the notes they produce
to ensure they are in tune. If they aren’t, they will adjust the position
of their fingers to bring the notes back in tune,” MacDonald said in the
news release.

“When we speak, we do something very similar. We subconsciously listen
to vowel and consonant sounds in our speech to ensure we are producing
them correctly. If the acoustics of our speech are slightly different from
what we intended, then, like the violinists, we will adjust the way we
speak to correct for these slight errors,” MacDonald explained. “In our
study, we found that 4-year-olds monitor their own speech in the same way
as adults. Surprisingly, 2-year-olds do not.”
