Political topics make great topics for oratory speeches, thanks to current events. Debating legislation in Congress, arguing about the benefits of an expanded role of government or America's involvement in world policy all provide good substance for a speech. Topics include issues affecting local, state and national governments, corruption, ethics, cost, taxes and regulation. Many topics quickly turn political, such as environmental or social issues leading to a whole new set of topics. Even the most basic political topics like arguing the merits of conservatives, liberals, socialists and libertarians make for good material. These speeches often rely heavily on studies and government research.
Good orators often have the same qualities as actors, so speeches about historical figures and history events make a good speech. Speakers playing the role of one of the signers of the Constitution arguing for the Bill of Rights, a woman playing the role of an advocate of women's suffrage, and recanting a historical speech by a president all captivate audiences while teaching a lesson. Include literary figures too, citing great works of literature while skimming passages of poems, fiction or essays. Informative topics about history can also cover some of history's great orators, including presidents, British royalty and world leaders.
Giving a good oratory speech about education doesn't just cover how to do well in school or tips to be a great student athlete, rather takes a speech up one level by using inspiration as a foundation. Speaking to young people about the importance of doing well in school, staying out of trouble, and aspiring to make a difference in the lives of others are all topics where speakers can use personal experiences to make a difference. A speech offering inspirational advice to students doesn't work for every audience, so choosing an audience that would benefit or be open to listening works best.
Good oratory speech topics include speeches about losing weight, sticking with a fitness program, eating healthy and quitting smoking. Topics can also include beating cancer, rebuilding life after a heart attack and coming back after traumatic brain injury. These orations become highly effective by introducing motivation, inspiration and good storytelling. Speaking before an audience and telling them how to change their life using personal experiences (even using the experiences of others) can motivate and inspire them to change. Skip the "doctor-speak" in these types of speeches, and stick with language people can understand.
