摘要：From the sociocultural point of view, the investigation of private speech is important in seeing how the mind works. Yet, not much is known about the form and content of private speech. A group of English language learners were required to talk about some topics of their reading courses. Their voices were recorded and the private speech used by them were identified. It was found that the main role of the loud and silent forms of the private speech in the data is to help learners manage the interaction. Private speech is embedded within the speech context and it needs to be explained in the context in which it happens.
