This document describes five different intonational styles of speech: informational, academic, publicistic, declamatory, and conversational. Each style has a different purpose and characteristic prosodic features. The informational style conveys information without emotion and has a low, stable pitch. The academic style is used for lectures and discussions and has systematic rhythm. The publicistic style aims to influence and involve listeners with a variety of pitches and volumes. The declamatory style appeals to both the mind and emotions with descriptive pitch movements. Finally, the conversational style is relaxed and unpredictable with irregular rhythm. Mastering these intonational styles can improve communication.
