Table 1: Foundational Delivery Techniques

Technique	Example	Description
Eye contact	Hold gaze on one person for 3–5 seconds, then move to another section	• Builds trust and connection by making individuals feel acknowledged • avoid scanning like a lighthouse—lock in and complete a thought with each person.
Vocal variety	Vary pitch, pace, volume, and pause: slow down for key points, raise volume for emphasis	• Uses volume, pitch, pace, pause, and emotion to prevent monotone delivery • strategic variation keeps audience engaged and highlights important ideas.
Diaphragmatic breathing	Inhale deeply, stomach expands; exhale through pursed lips, stomach flattens	• Powers the voice from the diaphragm rather than the throat • supports projection, reduces strain, and calms nerves through controlled breath.
Open posture	Feet hip-width apart, shoulders back, head aligned with spine, arms uncrossed	• Conveys confidence and accessibility • closed postures (crossed arms, hunched shoulders) signal defensiveness or discomfort.
Purposeful gestures	Use open palms to show honesty; point upward when discussing growth	• Gestures should amplify your message, not distract • match hand movements to content (expansion, contrast, enumeration) and avoid repetitive tics.
