If you find yourself being a reader in a public setting, like at Mass or something, read this short article.

• Miserable readers mumble.
• Bad readers go too fast.
• Good readers read slowly and clearly.
• The best readers read slowly, clearly and with emphasis.

The only way you can be the best reader is if you are familiar with the text and the tone that needs to be struck with the audience. Get familiar with it and figure out what are the most important points and emphasize them with alterations in volume or with cafeful pauses. That's it.
