A speech designed to __________ seeks to change or reinforce listeners' attitudes, beliefs, values, or behavior.

A speech designed to persuade is specifically aimed at influencing the audience’s attitudes, beliefs, values, or behaviors. The fundamental goal of a persuasive speech is to convince listeners to adopt a certain viewpoint or take a specific action. This may involve presenting arguments, utilizing emotional appeals, or highlighting evidence that supports the desired outcome. By effectively communicating the desired message, the speaker aims to evoke a response that aligns with their objectives, making the audience more amenable to change.

In contrast, an informative speech primarily focuses on providing knowledge and facts without an intent to influence beliefs or behaviors. An entertaining speech aims to amuse or engage the audience rather than to persuade them. Finally, while an engaging speech might capture the audience's attention, it does not necessarily strive to alter their viewpoints or behaviors. Thus, the act of persuasion distinctly identifies the type of speech that seeks to change or reinforce the audience’s perspectives.
