Every effective speech begins with a clear purpose, to demonstrate, inform, persuade, or entertain. Once the speaker knows why they are speaking, the next essential step is to decide what they will speak about by choosing a topic that fits that purpose. Selecting a topic requires balancing many factors: the professor’s directions, the time available, the type of speech, the audience, and the subject area. Students can also draw on personal experiences, areas of interest, credible online sources, and even tools like AI to help generate and refine ideas. This chapter will guide you through the process of moving from purpose to topic, showing how to narrow broad subjects into focused, audience-centered topics that work within the limits of a short classroom speech.

- Describe the relationship between a speech’s purpose (to demonstrate, inform, persuade, or entertain) and the process of selecting a topic.
- Explain how factors such as professor’s directions, time limits, type of speech, audience, and subject area influence the narrowing of a topic into a specific purpose.
- Interpret how tools like personal experiences, online recourses, and AI prompting can help transform a broad subject into a focused, audience-centered speech topic.
- 5.1: Purpose in a Speech
- This page emphasizes the significance of purpose in public speaking, detailing how it shapes goals and structures speeches. It distinguishes between general and specific purposes, applying them to speech types such as demonstrating, informing, persuading, and entertaining. Influences from classical rhetoric are cited to define these categories.
- 5.2: Selecting A Topic
- This page outlines the process of selecting an effective speech topic by aligning your purpose (inform, persuade, entertain) with appropriate subject matter. It emphasizes considering guidelines, time constraints, audience interests, and personal knowledge. It suggests using personal experiences and interests, as well as resources like the internet and AI for inspiration, to craft a focused and engaging speech that connects with the audience.
- 5.3: Narrowing your Topic
- This page emphasizes the importance of narrowing your topic for effective speech delivery within time constraints. It suggests focusing on key aspects relevant to the audience and purpose by identifying the core intent of the speech, selecting relevant subtopics, and limiting main points to three for clarity. Utilizing AI prompts for idea refinement, starting with broad prompts and moving to specific ones, ensures meaningful content delivery without overwhelming the audience.
- 5.4: Putting it all together
- This page outlines the speech topic selection process, emphasizing the importance of purpose—demonstrating, informing, persuading, or entertaining. It encourages narrowing the subject to match time constraints and audience relevance. Key strategies include following guidelines, assessing practical limitations, and reflecting on personal interests.
- 5.5: Glossary
- This page covers speech preparation, including types of speeches (deliberative, forensic, epideictic) and their purposes (inform, entertain, persuade). It highlights Aristotle and Cicero's contributions to rhetoric and the role of AI tools like ChatGPT in idea generation. The text underscores the importance of narrowing topics, main points, personal experiences, and the distinction between basic and in-depth prompts for effective speech writing.
- 5.6: Discussion Questions
- This page discusses the importance of identifying the general purpose of a speech—demonstrating, informing, persuading, or entertaining—to refine its specific goal. It highlights contributions from historical figures like Aristotle and Cicero and emphasizes the need to consider audience, time constraints, and topic relevance. Personal experiences can enhance engagement, while the internet serves as a tool for brainstorming and research, though it risks providing unreliable information.
- 5.7: References
- This page provides a collection of academic resources focused on public speaking and communication, including a book on audience-centered methods, an article on prompt engineering and AI, and a social psychology textbook. It also references online materials for topic selection in speech preparation and a philosophical entry on Aristotle's rhetoric, all of which contribute insights into effective communication strategies and the theory of rhetoric.
