Speech Basics

Core Concepts of Argumentation

• Thesis:
  • Definition: A clear, defensible main claim that takes a specific position and previews the line of reasoning.
• Line of Reasoning:
  • Definition: The logical sequence of claims an author makes, as well as the explicit connections between them, moving an argument systematically from evidence to conclusion.
• Claim:
  • Definition: A debatable assertion (distinct from a statement of fact) that takes a clear position and can be supported or challenged with evidence.
• Relationships Between Claim, Evidence, Opinion, and Trivia:
  • A claim made without supporting evidence is merely an opinion.
  • Evidence presented without an overarching claim functions merely as trivia.
• Argument vs. Line of Reasoning vs. Summary:
  • Argument: The comprehensive, complete package that includes the thesis, claims, evidence, and line of reasoning together.
  • Line of Reasoning: The structural framework of the argument—specifically the sequence of claims and the internal logic that connects them.
  • Argument without Claims: An argument lacking claims devolves into a simple summary.
  • Course Warning: Summary is the fastest way to lose points in this course.

Transitions and Signposting Guidelines

• Transitions to Avoid:
  • Overusing basic conjunctions such as "And…" or "But…".
  • Endless repetition of identical transition phrases (e.g., repeatedly stating "my next example is…").
  • Jumping randomly from one example to the next without clear structural connections.
• Signposting:
  • Definition: A signpost is a verbal or visual marker indicating the direction a speech or presentation is taking, or specifying where the speaker is currently positioned within the structure. Signposts help the audience navigate through different concepts, connect relevant points, and remain actively engaged.
  • Methods: Numbering examples sequentially, or verbally guiding the audience through evidence in a descriptive, clear manner.
• Helpful Signposting Phrasings:
  • Guiding the audience through material: Phrasing like "here’s an example".
  • Encapsulating complicated information: Clarifying complex ideas using statements like "Let’s be clear".
  • Showcasing key ideas: Directing emphasis to primary points using statements like "Here's the important point…".
• Unhelpful Phrasings and Verbal Pitfalls:
  • Repetition of crutch phrases: Saying filler expressions such as "literally" or "what’s important here" five or six times in a single speech degrades their impact, causing the phrases to become meaningless fluff.
  • Cliché expressions: Relying on overused stock phrases such as "at the end of the day" or "the bottom line".
  • Condescending or preachy tone: Using patronizing or lecturing setups such as "let me tell you…".
  • Unnecessary setup: Frame-setting statements like "let me tell you a story" instead of directly delivering the narrative.
  • Invitations to tune out: Signals that indicate the presentation is wrapping up—such as "in conclusion" or "before I wrap up"—which signal to the audience that they can disengage.

Best Practices for Speech Conclusions

• Avoid Abrupt Conclusions: Speeches should never end suddenly without proper closure.
• Signpost the Ending Effectively: Clearly signal the arrival of the final section without relying on uninspired or cliché phrases like "in conclusion".
• Summarize Key Points: Reiterate the main arguments clearly, simply, and definitively.
• Revisit the Thesis with Actionable Statements: Return to the central thesis by ending with a doable statement or practical solution aimed at resolving real-world problems.

Fundamentals of Public Speaking Delivery

• Enunciation, Speed, and Volume: Articulating words distinctly, maintaining an even pace, and projecting sufficient vocal volume.
• Posture: Maintaining a firm, balanced physical stance in front of the audience.
• Hand Placement and Gestures: Managing physical gestures purposefully rather than engaging in nervous or distracting hand movements.
• Vocal Fillers: Identifying and eliminating vocal pauses (such as "um", "uh", or repetitive filler phrases).
• Breathing: Utilizing proper breath support to maintain cadence, volume, and composure throughout the presentation.
