Read this article, which summarizes the basics of extemporaneous presentations, as compared to impromptu speeches.
Extemporaneous, the most natural method of delivery, involves glancing at notes while maintaining crucial eye contact with the audience.
Extemporaneous speaking is one of the most natural methods for delivering a prepared speech. You can use an extemporaneous speech to achieve a more natural tone, flow, and style with the audience.
First, think about your topics and anticipate the audience's reception to your speech. You can develop speech notes based on this preparation and use them to aid you during the presentation.
There are two popular methods for creating a graphical representation for notes: outlining, and mind or concept mapping.
An outline is a list of items with each item divided into additional sub-items. Each level in an outline has at least two subcategories. There are three basic types of outlines:
Speaking notes, topic outlines, and phrase outlines have an advantage over sentence outlines. For example, you can easily look at your notes for reference and as a personal reminder of which topics to discuss as you're speaking.
Outlines commonly take two forms: alphanumeric and decimal.
An alphanumeric outline includes a capitalized number or letter at the beginning of each topic. Look at the sample:
I. Thesis statement: Email and internet monitoring is an invasion of employees' rights
The decimal outline shows how each item at every level relates to the whole sample.
….1.1 Brief history of Liz Claiborne
….1.2 Corporate environment
2.0 Career opportunities
….2.1 Operations management
……..2.1.2 International trade and corporate customs
….2.2 Product development

Mind mapping and concept mapping are visual representations of ideas and concepts. A mind map is a diagram that starts with a single word and then branches out from the central node, with lesser categories as sub-branches of the larger branches. Concept maps are more freeform, since multiple hubs and clusters can be created. Unlike mind maps, concept maps do not fix on a single conceptual center.
For example, in the mind map for student learning, you can view the main component idea and related ideas which connect to its branch nodes. You can also use a mind map as speaking notes.
Mind Map: A mind map is a diagram that starts with one word and expands into additional categories.
The following guidelines are best practices on how to practice and rehearse an extemporaneous speech:
Although extemporaneous speaking may not require memorization and manuscript speaking, organize and prepare your content and notes ahead of time to deliver a speech that will be well received by your audience.
