Proper Use of Vocal Organs—Careful attention and training should be given to the vocal organs. They are strengthened by right use, but become enfeebled if used improperly. Their excessive use, as in preaching long sermons, will, if often repeated, not only injure the organs of speech, but will bring an undue strain upon the whole nervous system. The delicate harp of a thousand strings becomes worn, gets out of repair, and produces discord instead of melody. (Ev 667.1) MC VC

It is important for every speaker so to train the vocal organs as to keep them in a healthful condition, that he may speak forth the words of life to the people. Everyone should become intelligent as to the most effective manner of using his God-given ability, and should practice what he learns. It is not necessary to talk in a loud voice or upon a high key; this does great injury to the speaker. Rapid talking destroys much of the effect of a discourse; for the words cannot be made so plain and distinct as if spoken more deliberately, giving the hearer time to take in the meaning of every word. (Ev 667.2) MC VC

The human voice is a precious gift of God; it is a power for good, and the Lord wants His servants to preserve its pathos and melody. The voice should be cultivated so as to promote its musical quality, that it may fall pleasantly upon the ear and impress the heart.... (Ev 667.3) MC VC
