Know your audience. This is crucial to delivering your speech because your message is only as important as the recipients think it is. Learning as much as possible about the audience and what they value will help you form a speech that is inspiring. Find out why people will be attending your speech to better understand the audience's motivation.
Smile and relax. Regardless of how nervous you are, let people know you want to be there by smiling. Let your body language reflect a tone that is relaxed and friendly. No matter what the topic, there will always be moments to engage the audience in a smile. It is almost always the case that those who are well prepared, feel more relaxed when delivering their speech.
Speak with confidence. Speakers should always practice their speech in advance. This helps build confidence and greater familiarity with what you are saying without an audience present. If the speech is truly important, consider video-recording yourself or asking friends to watch while you practice. The feedback can help improve your speech, while watching your speech may prompt you to add something inspirational that you had inadvertently left out. Instead of later thinking, "I should have said...", you can make sure you include everything when you deliver the speech. If hearing your own speech inspires you, it will likely inspire others.
Maintain a positive attitude and position. Be passionate about your subject. Don't expect your audience to become more enthusiastic about something than you are. Your energy alone can be inspiring as long as it is expressed appropriately. Spark a fire with your energy, just don't burn the place down.
Be professional, while still showing some empathy and displaying human qualities. Use humor to your advantage. Engage the audience by involving them as much as is appropriate for the speech.
Speak clearly using language easily understood by your audience. Select your words purposefully and use powerful words. Avoid industry jargon and words that are long or academic.Instead, incorporate words that encourage emotion or stimulate a reaction.
Use examples and compose your message in a way that makes it accessible to your audience. If your speech is not on a subject that audience members can relate to, draw upon commonly shared life experiences to enrich your message and develop a bond with your audience. Provide solutions to problems.
