In the next place, distinctness depends upon enunciation. The debater who drops off final syllables, slurs consonants, runs words together, or talks without using his lips and without opening his mouth is hard to understand. It often requires considerable conscious effort to pronounce each syllable in a word distinctly, but the resulting clearness is worth a strenuous attempt. One great cause of poor enunciation is too rapid talking. A fairly slow delivery is preferable not only because the words can be more easily understood, but also because it gives a debater the appearance of being more careful and accurate in his reasoning. Great rapidity in speech may be due to nervousness or inexperience; whatever its cause, it is usually fatal to distinctness.
A pleasing tone of voice is not of so great moment as distinctness of utterance, yet its cultivation is by no means to be neglected. Harsh, rasping sounds and nasal twangs are disagreeable to hear, and no speaker can afford to offend his audience in this way. An unpleasant voice may be the result of some physical defect; more often it is caused by sheer carelessness. In most cases a little practice will produce a wonderful change. A very common breach of elegance in speaking is the habit of drawling out an er sound between words. The constant repetition of this is exceedingly annoying. It is usually caused by an attempt to fill in a gap while the speaker is groping about for the next word. The best way to correct this blunder is to be so familiar with what one is going to say that there will be no gap to fill in; but in case one does have to hunt for words, it is a thousand times preferable to leave the gap unfilled. Each word should stand out by itself, even though there is a pause of many seconds. To offend the ears of an audience with a crude tone of voice or with meaningless sounds is a bad violation of propriety.
The first step to be taken in the cultivation of a distinct and pleasing voice is to acquire the habit of standing correctly. Under the subject of position it was stated that the body should be kept erect, the head thrown back, and the shoulders rolled back and down. This posture is the best not only because it is the most graceful but because it gives the speaker the greatest command of his vocal organs. Stooping shoulders and a bowed trunk contract the lungs and diminish the supply of breath, and a bent neck renders the cords of the neck less controllable. After taking the proper position, one should next endeavor to breathe as deeply as he can. The louder he has to speak, the deeper should be his breathing. Remembering that he does not wish to talk fast, he will do well to fill his lungs at the close of each sentence, always inhaling, in order not to make an unpleasant gasping noise, through the nose. While speaking, he should control his supply of breath not by contracting the chest but by elevating the diaphragm. This procedure will give his voice a richness and a resonance that it otherwise could not have. Breathing merely from the top of the lungs means squeakiness of tone and poor control. One who breathes incorrectly will find it necessary to shout to make himself heard at a distance; one who breathes correctly can usually be heard under the same conditions by merely talking. The superiority of the round, deep tone over the shout is too obvious to need comment. In the next place, a speaker must think about this voice. Thought and study are as essential in the training of a voice as in the mastery of any art. A natural voice is not usually pleasing; it becomes so only through cultivation. Much of this training can be done by the speaker unaided. Few people are so insensible to qualities of sound that they cannot detect harshness and impurities even in their own utterance, provided that they will give the matter their attention. It is not enough, however, for one to watch his voice only while he is debating or while he is repeating his arguments in preparation for a debate; he must carry constant watchfulness even into his daily conversation. The services of a good instructor are invaluable, but at best they can be only auxiliary. All improvement must come through the efforts of the speaker himself.
ATTITUDE TOWARD OPPONENTS. If one will bear in mind that the fundamental purpose of argument—whether written or spoken—is to present truth in such a way as to influence belief, he will at once understand that a debater should always maintain toward his opponents the attitude of one who is trying to change another's belief, the attitude of friendship, fairness, and respect. Such a point of view precludes the use of satire, invective, or harsh epithets. These never carry conviction; in fact, they invariably destroy the effect that an otherwise good argument might produce. Ridicule and bluster may please those who already agree with the speaker, but with these people he should be little concerned; a debater worthy of the name seeks to change the opinions of those who disagree with him. For this reason he is diplomatic, courteous, and urbane.
A debater should, moreover, keep to this same attitude even though his opponent introduce objectionable personalities. One will find it for his own best interest to do so. Good humor makes a far better impression than anger; it suggests strength and superiority, while anger, as everyone knows, is often the result of chagrin, and is used to cover up weaknesses. Besides, an audience always sympathizes with the man who is first attacked. All this does not mean that a debater should calmly submit to unfairness and vilification. On the contrary, he should defend himself spiritedly; but he should not meet abuse with abuse. To do so would be to throw away an invaluable opportunity. He should remain dignified, self-controlled, and good-humored; then by treating his opponent as one who has inadvertently fallen into error, and by pointing out the mistakes, the unfairness, and the way in which the real question has been ignored, he can gain an inestimable advantage.
The following quotations show what attitude a debater should maintain toward his opponents:—
As I do not precisely agree in opinion with any gentleman who has spoken, I shall take the liberty of detaining the committee for a few moments while I offer to their attention some observations. I am highly gratified with the temper and ability with which the discussion has hitherto been conducted. It is honorable to the House, and, I trust, will continue to be manifested on many future occasions. (Henry Clay.)
Mr. President, I had occasion a few days ago to expose the utter groundlessness of the personal charges made by the Senator from Illinois against myself and the other signers of the Independent Democratic Appeal. I now move to strike from this bill a statement which I will to-day demonstrate to be without any foundation in fact or history. I intend afterwards to move to strike out the whole clause annulling the Missouri prohibition.
I enter into this debate, Mr. President, in no spirit of personal unkindness. The issue is too grave and too momentous for the indulgence of such feelings. I see the great question before me, and that question only. (Salmon P. Chase.)
Compare the attitude of Mr. Naylor in the following quotation with the attitude of Mr. Lincoln in his debates with Senator Douglas. It is needless to point out which must have had the better effect upon the audience.
