Understanding Heterogeneous Public Discourse and Speech Types

Heterogeneous Public Discourse

Public discourse is structured according to the speaker's intention. It encompasses various forms, each serving a specific communicative purpose.

Core Discourse Types

• Description: Represents the real world by detailing the characteristics, structure, and properties of an object. It is read in conjunction with the outside world, referring to the specific time and place of insertion.
• Explanatory: Aims to make an idea understandable. It follows a questioning phase and a decisive phase to ensure the purpose is clear.
• Narrative: Accounts structured by chaining events to build a story. It includes an initial situation (equilibrium), a complication (unexpected event), and an outcome (re-establishment of balance).
• Argumentative: Presents views and counter-arguments to convince, persuade, or influence actions.
• Dialogical-Conversational: Involves two or more participants with the aim of asking, promising, or thanking.

Aspects of Public Discourse

• Intention: The issuer's goal, such as informing, persuading, explaining, or reaching an agreement.
• Purpose: The specific objective to be achieved.
• Organization of Ideas: Ensuring consistency and logical flow.
• Discourse Forms: Utilizing various styles, such as expository, argumentative, or epideictic (praise), to connect with the audience.
• Hierarchical Relationship: The dynamic between the transmitter and receiver, often involving an asymmetric relationship where the issuer holds authority.
• Perspective: The issuer's stance toward the subject (e.g., objective, critical, admiring, or thoughtful).
