The proper use of the vocal organs will bring benefit to the physical health and increase the usefulness and influence. It is through falling into bad habits of speech that people become tedious readers and speakers, but those who are looked upon as intelligent enough to become missionary workers or to transact business ought to have intelligence enough to reform in their manner of speaking. By judicious exercise they may expand the chest and strengthen the muscles. By giving heed to proper instruction, by following health principles in regard to the expansion of the lungs and the culture of the voice, our young men and women may become speakers who can be heard; and the exercise necessary for this accomplishment will prolong life. (CT 247.1) MC VC

Those who gain correct ideas on the subject of voice culture will see the necessity of educating and training themselves so that they may honor God and bless others. They will put themselves under patient, efficient teachers and learn to read in a way that will preserve the melody of the voice. With an eye single to the glory of God they will make the most of their natural abilities. Commanding their own powers, they will not be embarrassed by defects of speech, and their usefulness in the cause of God will be increased. (CT 247.2) MC VC
