Speech is another activity you can compete in that also involves research and public speaking. Speech is part of the larger category of "Forensics" which involves acting, however, speech does not involve acting. Instead, there are different events where you can showcase your essay-writing and communication skills. For most of the speech events, you give a memorized speech in front of a judge. Unlike debate, there is no argumentation and nobody responds to what you say in your speech.
This is a great option for anyone who really likes the research and writing aspects of debate. These events require good public speaking skills because judges are evaluating your speech on your performance as well as the content.
The different events are described in detail in another post, so please head there if this sounds interesting to you!
