The answer is yes and no. You can read books, watch speakers in person or on videos and search Google for speaking blogs by people who speak for a living. You can gain a great deal of information which you can combine with practice and you will find yourself becoming better and better. It should only take you five years or so this way. What if you have do be a good speaker or presenter and you don't have five years? If you have to get to the top as soon as possible there is only one way. You need to do all of the above and make contact with the best speaker you can find. Professional organizations like Toastmasters have contests to vet their best. Contact that person and arrange to have them mentor you one on one. That person will know many little secrets he or she has gleaned from years of excellence.
