Keep in mind when you speak at a slower pace, your audience may start to become unengaged and lose interest faster. Maintaining a balance between a slow, clear delivery and maintaining the audience's interest is essential. Think of the scenario in your mind and try to visualize yourself speaking to a gym full of people. For example, maybe you need to sell a certain amount of items and you only have today, so how are you going to convince all of these people to buy them? If you were the audience, what would you think about the delivery?
