I wrote this for one of my MFA Acting students, but I think it’s relevant for all of us:
Speaking from the Bones
Before speaking, pause for a moment. Allow your chest and belly to soften, and find the support of your bones. If sitting, you could move in the chair a bit to feel your sit bones. If standing become aware of the skin contact of your feet with the floor. Try and get balanced evenly between both sit bones, or evenly between heel and toe and both feet. If standing let your knee (on the dominant leg) soften inward. If the knees lock out this will cut of your support from the floor, but it’s mostly the dominant knee that needs a little inward softening. It might feel knock-need.
Remind yourself that the resonance in your voice comes from your bones, not the muscles of your throat, and direct your neck to be easy, your head to float. Trust that the sound vibrations will resonate in the bones of your face and the throat and chest and shoulders can stay loose.
Even a little pause here and there will help maintain your energy and freedom
