Saying more by saying less can make some people shut down or quit listening. Add content to discussions that is as condensed as possible without being vague. Talking until you get to your point will ensure half of your audience has already tuned out. State your point up front and people will know what you are trying to elaborate about. If you have to give a speech and there's a time limit, don't squeeze in the thirty thoughts that come to your head. Pick the three most important ideas, and elaborate on those. Words such as um, a, like, etc... degrade and detract from what you say. They disturb the flow of a sentence and make it detached. A nonverbal pause is much better. When floundering for words, a nonverbal pause, placed correctly, gives the listener the effect of a dramatic or studied thought. It confirms your control over what is being said. Speaking more slowly, eliminating distractions, and making eye contact will also help you stick to your message. Another way to speak more clearly is to speak more slowly. You may feel that if you rush and say everything you wanted to say, that you'll be able to get it over with and make people see your point more clearly. However, if you take the time to slow down, think about what you have to say, and pronounce your words in a way that won't make you mumble or confuse your audiences, then you will actually be more well-spoken.  You don't have to speak…so…slowly…that you feel like you're pausing between every word, but pausing in between sentences to give yourself time to prepare your next sentence will do the trick. If you speak too quickly, there's also a chance that you will say something that you regret or that makes absolutely no sense, and you'll have to do some backtracking to make your audience understand what you really mean; you can avoid all that by speaking slowly to begin with. If you keep your hands in your pockets, you are more likely to stutter, forget what you have to say, or to confuse your audience. That's because using your hands to gesture can help you explain what you mean and can get your whole body into the speaking process. Communication doesn't just come from your mouth, but from your posture, your eye contact, your gesturing, and your body language -- it's part of a whole package. So the next time you speak, take those hands out of your pocket. Even if you don't use them to gesture a ton, you'll feel more comfortable if you gesture a little. Keeping your hands in your pockets will also make you look less confident, which will make your message look weaker. Another way to be more well-spoken is to be really focused on your message. You may be saying "um" and "uh" or forgetting your train of thought every few sentences because your phone keeps vibrating, because you're running late, or because you're worried about a meeting you have later that day. So, stay in the moment and focus on what you're saying when you're saying it as much as you can. If you are focused only on your message, you'll be able to deliver it more articulately, and your audience will pay more attention, too.

Summary:
Be more concise. Eliminate verbal pauses. Speak more slowly. Use your hands. Limit distractions.
