A recent insight has revealed that language learning could well begin in the womb.
Research which studied brain wave patterns found that babies begin to actually recognize words they have heard in the womb.
The fetus in the womb can hear sounds from the outside world and remember them even after birth. Researchers found that during the last trimester of pregnancy, the parts of the brain that processes sound actually become active. The sound does penetrate into the mother's abdomen and it is possible for the fetus to hear the rhythm of speech and music.
Despite this insight, there is no concrete evidence that exposing the fetus beyond normal sounds has any long term gains.
It is also important to consider the risks of over stimulation of the fetal ear and the developing brain. Excessive noise can interrupt the auditory system and disturb sleep cycles of the baby.
