Research shows babies begin to learn language sounds before they’re even born. In the womb, a mother’s voice is one of the most prominent sounds an unborn baby hears. By the time they’re born, newborns can not only tell the difference between their mother’s language and another language, but also show a capability of distinguishing between languages.
Language learning depends on the processing of sounds. All the world’s languages put together comprise about 800 or so sounds. Each language uses only about 40 language sounds, or “phonemes,” which distinguish one language from another.
At birth, the baby brain has an unusual gift: it can tell the difference between all 800 sounds. This means that at this stage infants can learn any language that they’re exposed to. Gradually babies figure out which sounds they are hearing the most.
