It must not be assumed that the throat is to be pampered.  A reasonable amount of exposure will harden it and to this extent is desirable.  To muffle the throat with a scarf, unless demanded by special conditions, may make it unduly sensitive and increase the danger of taking cold when the head is turned from side to side.

A leading physician confirms the opinion that the best gargle for daily use is that of warm water and salt.  This should be used every night and morning to cleanse and invigorate the throat.  Where there is a tendency to catarrh a solution made of peroxide of hydrogen, witch-hazel, and water, in equal parts, will prove efficacious.  Nothing should be snuffed up the nose except under the direction of a physician, lest it cause deafness.

Many speakers and singers have a favorite nostrum for improving the voice.  The long and amusing list includes hot milk, tea, coffee, champagne, raw eggs, lemonade, apples, raisins,—­and sardines!  A good rule is to eat sparingly if the meal is taken just before speaking.  It need hardly be said that serious vocal defects, such as enlarged tonsils, elongated uvula, and abnormal growths in the throat and nose are subjects for the specialist.

Whenever possible a speaker should test beforehand the acoustic properties of the auditorium in which he is to speak for the first time.  A helpful plan is to have a friend seat himself at the back of the hall or church, and give his opinion of the quality and projecting power of the speaker’s voice.  It is difficult to judge one’s own voice because it is conveyed to him not only from the outside but also through the Eustachian tube and modified by the vibratory parts of the throat and head.  A speaker never hears his own voice as it is heard by another.

Nothing, perhaps, is so taxing to the throat as long-continued speaking in one quality of tone.  There are two distinct registers which should be judiciously alternated by the speaker.  These are the “chest” register, in which the vocal cords vibrate their whole length, and the quality of tone derives most of its character from the chest cavity; and the “head” register, in which the vocal cords vibrate only in part, and the quality of tone is reenforced by the resonators of the face, mouth, and head.  The first of these registers is sometimes called the “orotund” voice from its quality of roundness, and is employed principally in language of reverence, sublimity, and grandeur.

The head tone is the voice of ordinary conversation and should form the basis of the public-speaking style.

No one who has to speak in public should be discouraged because of limited vocal resources.  Many of the foremost orators began with marked disadvantages in this respect, but made these shortcomings an incentive to higher effort.  One well-known speaker makes up for lack of vocal power by extreme distinctness of enunciation, while another offsets an unpleasantly heavy quality of voice by skilful modulation.
