A keynote speaker's primary responsibility is to serve as the conference's featured speaker. They are an advocate for the field in which they have excelled and amassed great expertise. They are able to energise an audience and provide an interesting speech focused on the issues established in a client brief. A keynote speaker can expertly present the skill set that has allowed them to assume their position as a thought leader in their field of specialization. They have the ability to convey information in novel ways, giving listeners new perspectives on a subject.

Keynote and conference speakers are able to quickly command delegates and speakers with convincing responses to pressing topics, enthralling audiences with fresh information, and reinforcing best practices to improve everyone's work and personal lives. Expert speakers can bring valuable insight to any private, organizational, or business gathering, as well as educational institutions, opening up avenues for creativity.

The closing keynote speaker's job is frequently to ensure that attendees stay until the very end rather than leaving early, hence the speaker and their subject matter need to be interesting to the audience. In the same way that the opening keynote speaker sets the "tone" for the event, the closing keynote speaker is also in charge of influencing how attendees remember the event and apply its lessons to their daily lives. Therefore, the final keynote speaker's messages must be motivating and upbeat. It's frequently a great idea to end the conference by expressing a very optimistic outlook for the future of the business or community that was represented there.
