Babies' literacy development!?

Babies May Pick Up Language Cues in Womb

NPR had a story today about babies and their tone when crying. It seems we start to develop language and perhaps literacy skills as early as inside the womb. Sweet! The study linked above studied German and French babies crying and found that french babies have a high pitch at the end where as German have a low pitch indicative of the native language spoken by the parents. Wow! The study points out that crying is not linguistic but that babies are able to echo the acoustic sounds they hear either in utero or very early on after birth. Amazing! I wonder how this then relates to the literacy development of a newborn. Does it play a key role or help language acquisition leading to literacy? The article talked about how it may affect bonding with members of the family as each group liked the pitch known for their language as well. Does it only have social impacts or any really?
