An informative speech is a fact-based speech intended to teach its audience about a specific topic. Informative speeches must have thesis statements and reliable sources for each claim. Some presenters opt to use slides, photographs or other visual aids to enhance their informative speeches.

An informative speech may focus on general information, such as the history of bread, or applicable information, such as teaching the audience how to bake bread. Unlike written informative essays, presentation is a key part of the effectiveness of informative speeches. Speaking too quickly or softly, losing place during the delivery of speech, using obviously biased sources and overloading the audience with information are common pitfalls when delivering an informative speech.

An informative speech is different from a persuasive speech because an informative speech provides just the facts and allows the audience to draw their own conclusions. In a persuasive speech, the speaker includes his conclusions and opinions in the speech alongside the sourceable facts.

The topic options for informative speeches are nearly limitless and are not limited to non-fiction ideas. For example, it would be possible to write an informative speech about the Harry Potter universe by using quotations from the books, excerpts from interviews with the author and sales figures from the publishing company.
