Speaking to large congregations as you do, it is your duty to give your vocal organs all the relief possible. When speaking, take deep, full inspirations of air. Use the muscles of the abdomen, and thus put upon them the burden you are now placing upon the throat and lungs. (VSS 261.1) MC VC

The Lord would not have you injure your vocal organs by a long, continuous strain. Your words will be much more forcible if you give your lungs more air and speak fewer words. When you are speaking, you need to give time to taking full, deep inspirations. Bring the muscles of the abdomen into action. Stand straight, breathe deep, and speak your words with as much force as you please. (VSS 261.2) MC VC

I was taught this lesson when my throat and lungs were so much affected that I could not breathe without suffering. No human friend gave me any hint of what to do in order to improve, but the great Medical Missionary, whom I love and obey, told me what to do. The directions given me, I give you. The importance of voice culture was impressed upon me, and ever since I have tried to impress this upon others. Let our ministers speak slowly, taking in full inspirations of air, and there will be a melody in their voices that is now heard in the voices of but few, because it is hard to change wrong habits for right ones. (VSS 261.3) MC VC

God would have His workers treat their vocal organs with special care, as a precious gift from Him. These organs are not to be abused by overtaxation. Let great care be shown in their use. Then the discourses given will be more impressive, and those who speak will be enabled to do more work for the Master. There are men who have gone down to the grave because they did not take pains to be in harmony with nature’s laws in their use of the vocal organs. (VSS 261.4) MC VC
