Many of us rush through our talk because public speaking makes us nervous. You need to speak slowly for a good speech, and to get that right, talk at the pace you would when telling someone a phone number.
Katie Schwartz of Business Speech Improvement says speaking slowly helps the audience understand you better, and it makes you sound more confident too:
A good benchmark is to speak slow enough that, if you were reciting a phone number, the person listening to you would be able to write it down. Practice your speech speed by reciting a long string of numbers, and writing them in the air as you do so. That's just about the perfect cadence.
Speaking slower can make you come across as more persuasive, but if you think your audience disagrees with you, you might want to switch to talking faster.
