This document provides tips for improving voice projection and body posture when public speaking. It recommends practicing deep breathing exercises to relax the throat and fill the lungs. The "volume exercise" of varying loudness with vowel and number sounds can strengthen projection. Maintaining correct posture with shoulders back, chest lifted, and chin up opens the lungs and facilitates airflow for clearer speaking. Strong eye contact with listeners also encourages projecting the voice louder. Daily practice of breathing and vocal exercises along with minding posture can boost confidence and performance for public speakers.
