english: Because sounds from the outside world have to travel through the mother's abdominal tissue and through the amniotic fluid that surrounds the fetus, the voices fetuses hear, starting around the fourth month of gestation, are muted and muffled.
non_english: Ker morajo zvoki od zunaj potovati skozi mamin trebuh in skozi amniotsko tekočino, ki obkroža zarodek, so glasovi, ki jih zarodek sliši nekje od četrtega meseca naprej, pridušeni in nejasni.
