This document discusses the features of pronunciation in English, including both segmental and suprasegmental features. Segmental features refer to individual sounds or phonemes, while suprasegmental features involve stress, intonation, and how sounds change in connected speech. It is important for English language learners to master both types of features in order to communicate effectively. The document provides examples of how word stress can change the pronunciation of words depending on their function, such as the words "record" as a noun versus a verb.
