What is the author's style in Uncle Tom's Children by Richard Wright?

American writers and cultural figures have concerned themselves with what black speech is and how to represent it from the earliest American literature to such contemporary cases as the Ebonix movement or Bill Cosby's objections to it. With Uncle Tom's Children, Wright makes a definite and interesting decision in depicting how black people talk. He chooses to represent his characters' speech and internal thoughts as phonetic, not "proper" English. On the one hand, this seems to split language into a hierarchy, with a high language, correctly spelled out on the page, and a low language, incorrectly spelled, that must be sounded out by the reader. On the other, this choice allows for the possibility that black English is a distinct form of the language and that understanding its meaning requires understanding it as a spoken language.
