what is a keynote speaker at a conference
Keynote At political or industrial conventions and expositions and at academic conferences, the keynote address or keynote speech is delivered to set the underlying tone and summarize the core message or most important revelation of the event. Some of the more famous keynote speeches in the United States are those made at the party conventions during Democratic and Republican presidential campaigns. Keynote speakers at these events have often gained nationwide fame (or notoriety); for example, Barack Obama at the 2004 Democratic National Convention, and have occasionally influenced the course of the election. In the commercial arena, Steve Jobs delivered influential keynote speeches at Apple product, system and service launches.[2]
State of the Union Both the Speaker and the Vice President sit at the Speaker's desk, behind the President for the duration of the speech. If either is unavailable, the next highest-ranking member of the respective house substitutes. Once the chamber settles down from the President's arrival, the Speaker officially presents the President to the joint session of Congress. The President then delivers the speech from the podium at the front of the House Chamber.
