An important point to note is that the function covered by caretaker speech, that of assisting a child to require language in small and simple steps, an unconsciously used but extremely important part of the process of language acquisition and such is quite universal. Studying cultures where children do not acquire language through caretaker speech is difficult because such cultures are difficult to find. The question of why caretaker speech is universal is not clearly understood; instead, proponents on either side of the nature versus nurture debate argue over whether caretaker speech is a natural function or inherent function in human believe that it is human nature for children to acquire language and for those around them to encourage their language acquisition naturally, the presence of a child is itself a natural stimulus that increases the rate of caretaker speech develops through nurturing rather than nature argue that a person who is attempting to communicate with a child will learn by trying out different ways of communicating to determine which is the most effective from the reactions to the communication attempts; a parent might, for example, learn to use speech with exaggerated inflections with a small child because the exaggerated inflations do a better job of extracting the child’s attention than do more subtle inflections. Whether caretaker speech results from nature or nurture, it does play an important and universal role in child language acquisition.
