What are some public speaking tips for construction executives? Public speaking is a skill that can be learned. Although some people may be more natural at public speaking than others, there are exercises, books and training programs that can make almost anyone successful at public speaking. A few basic tips include the following: research your audience to know what they are most interested in hearing about regarding your topic; prepare your speech well in advance and rehearse your delivery between 30 and 50 times so that you no longer have to think about it; try to grab the audience verbally and visually since most people remember what they see more than what they hear; dress one level above your audience to communicate an image of authority; be enthusiastic about your message and don't forget to smile often.
