Below are some speaker quotes that I found to be
“The right word may be effective, but no word was ever as effective as a rightly timed pause.
Mark Twain (1835-1910, American author and humorist)
“To be an impressive public speaker, you have to believe in what you are saying. And if you speak with conviction and you’re passionate about your subject, your audience will be far more forgiving of your mistakes because they’ll have faith that you are telling the truth. My answers aren’t always smooth and immediate, and often include a fair few ‘erms’ and ‘ahs’. But most audiences are far happier with a hesitant, sincere response than a speedy but superficial answer. Prepare, then take your time and relax. Speak from the heart.”— Richard Branson
