Start with diaphragmatic breathing. Inhale deeply so your stomach expands, and speak from your diaphragm rather than your throat. This deep resonance instantly lowers pitch and increases volume control. 2. Implement the 'pause strategy'. Never rush to fill silence. Pausing before key statements creates anticipation and shows high self-possession. Remove filler words (like 'um', 'like', 'ah') by pausing instead. 3. Modulation is key: slow down for critical insights and project your voice to the back of the room.
