This document outlines ways to speak powerfully and effectively so that others want to listen. It discusses avoiding "seven deadly sins" of speaking like gossip, negativity, and complaining. Instead, speakers should focus on honesty, authenticity, integrity, and speaking with care and goodwill for others. The human voice is a toolbox with tools like register, timbre, prosody, pace, pitch and volume that can be used consciously to engage audiences. Warming up the voice is also important for effective speaking. The goal is to create, receive, and design sound consciously so communication becomes more understanding.
