Most people are self conscious or preoccupied with volume and accents. Yes Volume is important. The audience needs to hear you. Accents are interesting, sometimes endearing. The focus should be more on clarity and avoiding being monotone. Having good vocal impact involves energy, enthusiasm and emphasis. As a speaker, it is your role to interpret the data, highlight key element s and make them memorable and believable. So, even if you are preaching or lecturing - people like to feel that they are being spoken to, personally. A conversational style is in most cases, is engaging. Some people turn off if they feel they are being preached to. Asking a few rhetorical questions helps vary the pitch; if overdone; the whole speech can come across as a little formulaic, cheesy or a little sing song. Some bold statements, quiet enquiry, soft slow delivery followed by fast paced excited examples, all lead to one concept - Variety!
How to make a presentation
Some people are given a title and thrown some slides from a presentation done by a colleague and quite rightly think “where do I start?”As you are the one who has to deliver the material, you need to own it, therefore even if you have to deliver a pre-prepared speech, keep your particular audience in mind and review the material, re-shape it, if allowed, and add your own examples.
Finding the data is usually not the problem. We are burdened with data all the time. Too often presentations are data -rich but message poor. The art of public speaking is to illustrate and interpret the data, draw the audience’s attention to key elements, make it memorable and easy to recite or enthuse to others. The objective could also be a call to action.
