Moms change the tone of voice when talking with young children, American scientists have discovered.

Timbre is a unique sound quality. It is the reason that a piano sounds different than a violin, even if they play the same note.

As shown by the results of the experiments Pristanski children’s lab, women speak in different voices, depending on who you’re connecting with adults or children.

Scientists have discovered that this quality is typical for women regardless of the language in which they speak.

“This mother is very consistent: they all share this change (tone. – Ed.), when they “switch” between the regimes,” says Dr. Elise Piazza.

“Voice imprint”

Think baby talk with children, which is characterized by a change in speech speed and the pitch of the voice, helps kids develop language skills. But the change of timbre was discovered for the first time.

When you call the voice is nasal or breathy, scratchy, or silky, you are talking about its sound.

The researchers recorded the voice of the mom, when they interacted with their child in age from seven to 12 months and adults.

The researchers then removed the “voice fingerprint” by analyzing the spectrum of sounds.

The study involved 12 English-speaking mothers. The results published in the journal Current Biology.

For the study the voices of moms who speak other languages, have developed a computer program that determines the difference in the tone. She can detect it in less than one second.

The change in tone found in 12 women who speak in different languages, including Hebrew, Mandarin and Cantonese dialect of the Chinese language.

“There is significant research which shows that kids learn better with a “baby” language (baby talk) than an adult,” says air force Dr. Piazza.

“So they better divide the word into syllables and learn better. And, this is probably due to these timbral features,” she adds.

The study did not analyze the language of fathers and grandfathers, but scientists predict that their tone is changing.
