Pacing your speech can be difficult, especially if you're feeling nervous or inexperienced. To ensure success, it's important to avoid common pacing mistakes. Speaking too fast can make you seem anxious, impatient, or unprepared, while speaking too slow can make you seem bored, tired, or unsure. To slow down, take deep breaths and relax your muscles; to speed up, energize your voice and use gestures and expressions. Additionally, filler words like "um", "uh", "like", or "you know" can make you sound unprofessional or unconfident. To eliminate them, plan and practice your speech, use notes or cues, and replace them with silence or meaningful words. Pauses and transitions can also help break up your speech and give yourself and your audience time to process. By avoiding these pacing mistakes and using variations and contrasts to create dynamism and excitement, you'll be able to deliver an engaging speech that captures the attention of your audience.
