1. Examples of speech openers:

Ask a thought-provoking rhetorical question and directly answer it with your claim.

State an amazing fact or statistic they probably never have heard of.

Offer a stirring example.

Cite a quotation or funny remark that describes the situation you are going to talk about.

Make an very controversial statement.

Tell a compelling anecdote nobody knows.

Give a definition of an expert to enhance credibility. But be creative in defining your ideas.

If you are dealing with demonstration speech topics then show the object of you speech.

2. Do the research so you know what you are talking about and can keep your audience spellbound:
