Persuasive Speeches

Promote a "point of view"

Demonstrative Speech Body

The body of a demonstration should never contain too many numerals or steps. To keep the process simple, group the steps into categories.

Speeches exist on an informative-persuasive continuum.

True- Speeches frequently exist on an informative-persuasive continuum, with some presentations clustering around the informative end and others tending toward the persuasive.

Inform Speeches

When you deliver speeches to inform, you seek to educate and enlighten your audience — not to influence their beliefs, feelings, or behavior. Four categories of informative speeches are description, demonstration, definition, and other informative types (reports, lectures, and personal experiences). The descriptive speech is related to a person, place, object, or event. The demonstration speech describes a process: how something works, how something is made, how something is done, or how something happens. A speech of definition identifies and explains a theory or subject area. Three other informational types are the report, which is used primarily in organizations and institutions; the lecture, which is presented by experts; and the personal experience

demonstration speech

a type of informative speech which usually includes a variety of visual aids to show the steps of a process

Aristotle's thoughts on Speeches

all speaking is persuasive; speeches differ only in the relative strength and weakness of the persuasion.

Lectures

can be fascinating if the speaker is knowledgeable, has structured his talk effectively, and communicates new or complicated information creatively

Definition Speech Outline types

chronological sequence; the second employs topical order.

The speaker employs vague generalities and uses no concrete supporting materials. This description will have little impact; the speaker has lost a wonderful opportunity to arouse interest.

Persuasive Speeches are only emotional

false- although persuasive speeches should make use of strong emotional appeals, they should also be grounded in supporting evidence that incorporates sound logic and fact.

Informative Speeches are only factual

false- informative speeches can contain supporting materials such as statistics, surveys, or polls and visual materials such as graphs, maps,and charts. But informative speeches should also incorporate emotional elements such as personal experiences, illustrations, and examples that interest the audience.

definition speech

inform your audience about a philosophical concept, such as a theory or idea, or a more concrete subject like a science or art

informative speech

informative speech promotes understanding, enlightenment, and education about a topic

Organizational principles of outlining speech

main points of the body should be arranged according to chronology, space, cause-effect, topic, or a combination of sequences.

report

often required in business or industry, often incorporate visuals: PowerPoint slides, transparencies with overhead projectors, chalkboards, whiteboards with Magic Markers, and flipcharts on easels

lecture

presentations that are given by experts for instructional or educational purposes. Colleges and universities often receive grants to invite well-known authorities in science, humanities, and industry to speak on topics of national interest. Lecturers frequently read lengthy presentations from manuscripts and incorporate question-and-answer sessions at the end.

descriptive speech

speakers inform audiences about persons, places, objects, or events. (Note that an object includes both the animate and the inanimate, and an event is defined as an incident or an occurrence.)

personal experience

speech provides information about an encounter or observation. Travelogues, harrowing adventures or expeditions are good subject areas for personal experience speeches. These presentations are often exciting and interesting; they are also potentially boring. Use good judgment in developing the topic, and be sensitive to your listeners.In your speech
