Which outline is primarily used during the delivery of a speech?

The speaking outline is fundamentally designed for use during the actual delivery of a speech, which makes it the correct choice. This type of outline is typically condensed and formatted to allow the speaker to follow along easily without being overwhelmed by excessive detail. It often includes key phrases, main points, and reminders for vocal emphasis or gestures, making it practical for maintaining the flow of the presentation while accommodating the natural speaking rhythm. The speaking outline serves as a prompt, enabling the speaker to connect with the audience and deliver the message confidently without reading verbatim from a script.

In contrast, a working outline is more of a preparatory tool that helps in organizing thoughts and developing the structure of the speech, but it is not the version used during delivery. The complete sentence outline is comprehensive and too detailed for performance use, as it might inhibit the speaker's spontaneity and engagement with the audience. Meanwhile, the expositional outline focuses on explaining concepts or ideas in a way that is often more extensive than needed for a concise speech delivery. Thus, the speaking outline’s practical design and tailored format for live presentations make it the most effective choice for delivering a speech.
