Prior research is essential. I have seen plenty of speeches fall flat in my time because the maker had not taken the time to gauge the demography of the audience. For the most part, speeches need to have universal appeal, but it is highly unlikely that you’ll be speaking to a group made up of a single generation, ethnicity, or cultural mind-set. When drafting your content, ensure that you seek pertinent information about the delegates – including their age, culture and language – as factoring this into your delivery will help you to achieve the desired impact of your speech.
