Just pause.
When you listen to someone with a very thick accent, it can be difficult to understand what they’re saying. But if you give your brain a second or two, it processes their meaning and feeds it to you.
Being a fast talker is like having a thick accent.
Whether you’re nervous, new, or just from a fast-paced region like New York, if you’re a fast-talker, you’ll risk losing your audience. Eventually, you’ll be given well-intentioned advice to slow down.
Don’t slow down. It’s unnatural for you and, frankly, really difficult to do for more than a sentence or two. Then you’ll find yourself back to a hundred words a minute.
Just pause.
Present your ideas at your normal speaking pace, but pause between sentences to give your words time to sink in; time to let your audience’s brains process what you’re saying and catch up with you.
Then carry on.
