In one sentence, describe what the following article is about: A strong posture is one of the most telling signs of confidence. Suffice to say, it's a look you'll want to have whenever you're speaking publicly. Keep your back straight, and your shoulders jutted outward. If you're someone who struggles with a slouched posture, it may take some time to reprogram yourself. After a while, however, you'll be able to do it without thinking. If you're nervous, your face will freeze up. Words alone only go so far in communication. The best speeches are emotionally hard-hitting, and it's intensified when the same feelings are being mirrored by the speaker. Whether rehearsed or not, matching facial expressions will lend your speech with a great air of authenticity. Don't force it, however. While you certainly want to make yourself animated, you don't want to appear unnatural. You want your expression to match your tone and words. Whether you're speaking on stage or something more casual, chances are there's a larger physical space you could be occupying. Even if you're the most riveting speaker, there is going to be a part of your audience that wants to be engaged visually as well. Getting your audience's eyes to follow you as you stride across the stage will make your presentation (and topic) feel all that more dynamic. If you're addressing the audience directly with someone, you should walk towards them on the stage. This creates an effect of urgency. It's best to move while you're transitioning to a new topic, as this let's the audience know that something is about to change. Eye contact is essential if you want to foster a connection with the audience he's speaking to. This doesn't need to be a constant thing, and you don't need to make eye contact with each individual in the crowd. Instead, simply scanning your eyes around the your audience from side to side can instill a sense of interaction between the speaker and his attendees. Pace yourself. While you don't want to stare at any one person for too long, you don't want to skim too fast either, or you'll appear nervous. If you find yourself skimming too much, consider focusing on the wall behind the audience. Don't stare at it for too long--keep your gaze moving slowly. Body language is a powerful tool on the stage, but it's only worth as much as it relates to the topic you're speaking about. Think of hand waves and gestures as exclamation marks in your speech. By using your body as an additional form of communication, you can ride home your point on multiple levels. Keep your gestures natural and spontaneous. Match them to what you are feeling. If you feel an urge to clench your fist or raise your arm, do it! Rehearsing gestures ahead of time is not always a good idea, as they may end up looking forced, static, and unnatural. However, you can rehearse your speech in front of the mirror and watch how you move naturally. Above all, you should keep every noticeable movement of your body under control when you are speaking. Many people will fidget and squirm when they're nervous. This isn't the sort of impression you want to get across if you intend on a successful presentation. Your body language should not be left up to whim or chance. If you're not comfortable with public speaking enough yet to balance the vocal presentation with purposeful body language, it is preferable to keep yourself completely still. Rest assured, unconscious movements are going to work against your presentation. Consider practicing your speech in front of a friend or family member, and ask them to note any fidgeting or squirming. Alternatively, record yourself giving your speech, then watch the recording. Look for any subconscious movements, such as playing with your hair.
Summary: Keep a firm posture. Allow yourself to express emotion through your face. Stake a claim on your personal area. Scan your eyes across everyone you're speaking to. Use gestures in tandem with what you're saying. Keep your movements controlled.
