Having a strong vocal platform is an essential ingredient for speakers. Whether you are speaking for 10 minutes or all day, developing a strong speaking platform will make your voice more engaging, and not to mention you will still have one at the end of the day.
We all breathe, however, many of us do not breathe correctly. Practicing the correct way to breathe can be the difference between having a voice for the duration of your talk, or ending up with a painful throat and a tired voice.
The first key is breathing from the diaphragm. To test this, stand up! Shoulders back chest out, head straight. Now place your hand on your belly take a deep breath and notice if the breath is raising your hand or if your shoulders are rising. If your shoulders are rising your breath is shallow and you vocal platform will not hold up. Practice breathing from the diaphragm and you will have a strong and more lasting voice.
If you are having trouble breathing from your diaphragm, lie down and place your hand on your belly and take a deep breath. You will feel that you are breathing from the diaphragm. Your hand will rise and fall. Ever wonder why a baby can cry for long periods of time. It is breathing from the diaphragm, or so I was told.
