　　3、Throughout the world, parents talk differently to babies than they do to adults. With their young kids, parents use baby talks, featuring long pauses and a roller coaster of pitch(音高)changes.

　　While parents may feel a bit silly using baby talks, they shouldn't in fact. Babies not only prefer listening to them, but they also learn new words more easily from them. By highlighting the structure of speech, such as the differences between the vowels(元音)"a" and "o", baby talks help babies translate sounds into meaningful units of language.

Actually, the timbre(音色)plays a role. The timbre of an instrument clearly affects how we experience music, but its role in language is less obvious. Looking into the timbre of baby talks, researchers made some surprising discoveries. In a new study published in Current Biology, researchers reported for the first time that mothers shifted their overall vocal timbre when speaking to their babies, as if they were changing their voice into a different instrument to address these unique little listeners.
