Every seminar, convention, or even a technical meeting requires a focus that can be provided by a keynote speaker. This speaker can then impart a topic or consideration for the event that can help in bringing all the delegates together.
A good speaker has to be one who is comfortable with the topic that is the central point of the speech and must have credibility and reputation that is acceptable to all the delegates or people attending the event. A speaker who connects with the audience and does not give the impression of talking down to them is more likely to be successful. Humour and a facility for simple and easy-to-hear language make such speakers more effective. The speaker must have the ability not only to speak but also to listen, as Q&A sessions are the ones that most audiences give their full attention to.
