One of the most important tools to effective communication is giving yourself enough time to prepare and plan for your presentation, speech or interview. Even during a conversation, you can still take a few moments to think about what you're going to say before you say it. For longer talks or speeches, make notes or jot down important ideas that you must mention in support of your position.
You're not always alone when presenting your ideas. There are usually plenty of aids that you can use to supplement your communication. For example, you can print out hand-outs, have a slide show or use a marker board to enhance your confidence and your ideas. What you wear is also important, so dress the part for formal presentations or meetings. Wearing a suit or neat, attractive clothing can be a valuable tool for confident communication.
Practice what you are going to say before you say it. Rehearsal seems obvious, but is often overlooked by ineffective communicators. Practice in front of a mirror or with close friends. Simply let the words come out of your mouth until you are comfortable saying them. Rehearsing what you are going to say builds your confidence and results in a smoother presentation.
Another important part of your toolbox is understanding nonverbal communication. Whether you realize it or not, what you do with your hands or body while speaking can either add or detract from what you are saying. Keep overt hand gestures, pacing or unnecessary movement to a minimum so your audience can focus on your ideas, not your movements. Film yourself rehearsing if possible to detect and correct distracting nonverbal communication.
Communication is not a one-way street; you must speak and listen, even if you are doing most of the talking. Pay attention to your audience and anticipate its needs rather than presuming. Open up the floor for questions after key points or if you think you are losing your audience. Frequently an audience question can point out an under-explained point or help you move on to your next idea.
