Breathe by the diaphragm and speak as you exhale
We are used to breathe by the lungs. Sound with such breathing is less expressive.
Try putting your palm on your stomach. Inhale the air so that the stomach grows larger and your palm comes forward. As you exhale, say the phrase. Feel how much sound is brighter than usual? Practice diaphragmatical breathing and use this technique when communicating with the public.
