Prosody is the study of rhythm, intonation, stress, and other attributes in speech and poetic meter. It includes features such as stress, pitch, intonation, pauses, loudness, pace, paralinguistic features, and vocal effects. Stress refers to emphasis placed on syllables or words. Pitch is variation in vocal range used to convey meaning. Intonation are patterns of pitch used in language. Pauses and loudness can change meaning depending on context, while pace varies with situation and mental state. Paralinguistic features and vocal effects provide extra linguistic information.
