Speaking anxiety is commonly caused by fear of judgment, lack of experience, low self-confidence, and fear of failure or forgetting lines. Preparation and practice are essential tools to reduce this nervousness, as they help build familiarity with the content, improve delivery, and boost confidence. During a presentation, speakers can stay calm and confident by using techniques such as deep breathing, maintaining eye contact, positive self-talk, pausing when needed, and focusing on the message rather than the fear.
