1) Attitude and confidence are important for effective public speaking. Speakers should avoid negative self-talk and focus on staying relaxed and conversational.
2) Proper vocal techniques include speaking loudly and clearly at an appropriate pace and pitch. Body language also matters, so speakers should maintain eye contact and limit unnecessary movements.
3) Thorough preparation is key. Speakers should practice their speeches out loud daily and be familiar enough with the content to maintain engagement with their audience.
