SPEAKERS, ADDRESS THE AUDIENCE 

When presenting, taking into account the overall character of an audience is essential. If the audience is young, exploratory and in the business of finding new facts on issues for the first time, then language appropriate to their level of understanding is essential. Similarly, if dealing with an audience well-qualified in the area being canvassed, “speaking down” to them would be conciliatory and insulting. Audience-specific language is essential. That adds to the credibility and the respect held for the presenter. In this context, it’s vital to know what audience is going to be addressed and to have an understanding of the background before delivery is important.
