The truth is that captivating an audience is a skill that may take years to polish and develop but there are some simple ways to improve one's public speaking and presentation skills instantly and the sections below discuss some of those tips and they are derived from some of the most famous speakers on TED talks.
The speaker has to always give the audience something to say and every good speaker needs to be able to provide something specific for the audience to do almost immediately because no matter how inspiring the message every audience appreciates knowing a tangible way that they can actually apply what they have learned to their own lives. Inspiration is great, but the application is everything thus the speaker needs to give the crowd something to apply.
You should never defer answering questions, and the fact that a question pops in between the presentation means that the person is listening and the speaker should seize the opportunity, and if the individual would have addressed the question in a later slide, then they can skip ahead. The truth is that if the individual has practiced skipping around, then the question will not throw them off balance, and the best presentations feel like conversations even if they are one-sided thus the person should never downplay the chance to foster that sense of interaction and never do anything to disengage the audience.
The speaker needs to ask some questions that they cannot answer and in as much as asking questions to the audience feels forced they can ask a question that the crowd cannot answer and then state that even they themselves cannot answer it either. After answering the question the speaker then needs to explain why they cannot answer it then talk about what they know and in most cases many speakers have the answers and the fact that one speaker does not have a reply and they are willing to admit it then it humanizes them and makes the audience pay greater attention to what they know.
The Essentials of Training - Breaking Down the Basics
The speaker needs to fuel their mental engine by consuming a diet that is rich in proteins before they go for the talk because proteins have tyrosine which is an amino acid that creates dopamine and epinephrine which are important for mental alertness. The speaker needs to burn off some cortisol because cortisol is secreted by the adrenal glands when one is stressed, or anxious and high levels of cortisol can limit the creativity and ability to process complex information and when the person is buzzed on cortisol it is almost impossible to react well to the room. The simplest way to burn off cortisol is to exercise by doing simple things like working out after work, taking a walk over lunch or hitting the gym before a public speaking engagement.The Beginners Guide To Options (What You Need To Know To Get Started)
