You might be thinking, tell me something I don’t know, but you’d be surprised at how many people mumble or bumble through their speech. One of the key things prior to giving a best man speech is preparation; if you know your onions you’re going to be fine. Stand up, take a deep breath, smile, engage your audience and once you’ve started, make sure you speak from deep within (the diaphragm), while pronouncing every word as fully as you can. To make sure you maintain a good speaking pace, think of the intro to a slow paced song you like and use that as your queue to start each new sentence. If people can’t understand you, your speech will be redundant – and nobody wants that.
