What type of speeches often involve a "how to" approach?

The type of speeches that often involve a "how to" approach is speeches of demonstration. These speeches provide a step-by-step guide on how to accomplish a task or understand a process, effectively teaching the audience through example. The "how to" format is crucial because it allows the speaker to illustrate procedures, show materials, and engage the audience practically. This hands-on approach not only helps in clarifying the process but also makes the content more relatable and memorable for the audience.

While speeches of explanation also relay information, they may not necessarily adopt a practical approach like demonstration speeches do. Instead, they focus on clarifying ideas or concepts. Informative speeches aim to provide the audience with knowledge on a topic without the emphasis on step-by-step instructions. Persuasive speeches seek to convince the audience of the speaker's viewpoint, rather than instructing them on how to do something. Thus, the clear, instructional nature of demonstration speeches aligns perfectly with a "how to" format.
