Language Learning
How do babies learn to speak? Babies pay attention to the speech they hear around them before they can speak. Young babies respond to the sound of the human voice differently to other sounds. They will stop crying when they hear a person talking, but not if they hear a bell. Very soon, the differences in adults'' voices can influence babies'' emotions. Long before they can understand language, babies can sense when an adult is playful or angry. By twelve months old, babies can produce single words such as mommy or daddy. Then, they may copy short phrases. They also learn to use the same words or phrases for different purposes. For instance, "Mommy drink" might mean "Mommy is drinking" or "Mommy, I want your drink". At around age three, many toddlers can speak complete sentences. Adults also exaggerate their speech so that babies can pick up a language easily. This is often called "baby talk". Baby talk is different from the way adults speak to each other. For example, when mothers talk to babies, they speak louder and slower. Mothers also use short, simple words or sentences with a highpitched soft tone of voice. Baby talk is more effective than normal speech to get a baby''s attention. Studies have shown that babies prefer to listen to baby talk.
