Although public speaking frightens many people, coming up with a speech topic may also be daunting. Choose a speech topic that is interesting and meaningful to you. Whether it is an informative speech or persuasive speech, make sure that you explore several aspects of the topic. When more than one perspective on an idea is addressed, your argument becomes stronger. Try to get to the heart of every issue, examining the root of the topic and its impact on the human condition.

Existence of Aliens

A speech about alien existence has potential to unearth many meaningful issues that stem from the core of human existence. Alien existence speeches remind listeners of the incredible magnitude and mystery of outer space and of the miracle of life on earth. Since the beginning of time, we have wondered where we are, who we are and what our purpose on this earth is. An exploration of the existence of life forms other than those on earth allows students to entertain wild possibilities, whimsical historical theories and challenge religious and social beliefs using scientific facts to back them up.

Gay Marriage

A speech on gay marriage allows students to challenge or protect conservative social and religious viewpoints and offer a new perspective. The issue of gay marriage has its roots in the nature and the value of love. It points to social stigmas and prejudices that have strong historical significance. Homosexuals have been discriminated against for centuries. The gay marriage speech explores the nature of homosexuality, morality, ethics, religion and the value of personal choice. It asks listeners to consider their priorities and form a strong opinion based on deep-rooted personal beliefs.

Vegetarianism Beliefs

The topic of vegetarianism allows students to explore where and how human beings fit into the food chain. Unlike many other animals, humans have the ability to choose what they eat and can survive with or without meat. Since animal flesh is not a necessity for human survival, it raises moral and ethical questions as to whether it is acceptable for humans to kill or hunt for pleasure. This issue calls the value of human life verses the value of animal and plant life to the forefront of the discussion. Does the life of an animal have less value than the life of a person? Students can also explore health benefits and pitfalls of consuming meat and the environmental consequences of factory farming.

Effects of Cellular Phones

Cellular phones have had an enormous social impact on the world's culture. They are essential companions for every civilized person of the 21st century. Students can explore the impact cellular phones have had on people's personal lives, awareness and sense of privacy. A speech on cell phones has its roots in the rapid evolution of technology and its incredible impact on human culture. New technology, media and internet has catapulted the youth of today to new levels of power and understanding than ever before. Explore ideas about the future, the role technology will play and the downfalls of the technological revolution.

Atomic Energy

Sometimes the source of the greatest power is the source of the greatest destruction. Atomic energy is highly controversial because of its incredibly detrimental effects if it goes out of control. At the same time, humanity searches for a source of clean energy to keep their cities running without destroying the ecosystem. Atomic energy is a double-edged sword. A speech on atomic energy explores both the pros and cons of yielding a great power for one's own use. It uses facts and statistics to measure the benefits against the consequences. This speech has its roots in human nature and addresses the issue of human imperfection.
