What is the author's style in Speaker for the Dead by Orson Scott Card?

As a science fiction work, the book includes many different types of languages for each of the creatures involved in the story, including the humans. This does not make the words used in the novel confusing, however. Even though Portuguese is foreign to many readers, it is translated within the text for easy understanding. The other languages are only spoken about and not actually used in the text of the story, keeping the confusion to a minimum when a character chooses to speak in a language that is not English. Overall, the novel is easy to understand despite the incorporation of many different languages.
