More physical facility is not enough for a good and effective voice. You must also have a clear mental picture of precisely the quality of the voice and of other aspects of speech you wish. Only through an adequate fullness or volume of tone can speakers influence and convince their audience. Resonance amplifies the fundamental tone of the voice and enriches it by adding over tones or partial tones.
Train Your Ears
More physical facility is not enough for a good and effective voice. You must also have a clear mental picture of precisely the quality of the voice and of other aspects of speech you wish.
We speak as we fear. Hence, the need to train the ears in order to cultivate keen perception, sensitive feeling, and finely developed aesthetic sense.
If you wish to improve your speech, you must watch the speech of the experts.
You need to distinguish the cultivated person from the ignorant and untutored, the kindly and generous one from the mean and disagreeable.
You need to listen for slurred and drawled sounds, differences in articulation, unevenness in the quality of the voice; for varied pronunciation, crisp and clear consonants, beautiful vowels, annoying speech mannerisms such as "Uh . . . Ah . . . See! . . ."
You need to observe carefully the range, pitch, variety, control, and qualities of various voices.
You need to listen to yourself talk so that you can detect defects and weaknesses of your voice.
Use Enough Volume to be Effective
Only through an adequate fullness or volume of tone can speakers influence and convince their audience.
Speakers who speak too loudly or who do not speak loud enough to be heard are considered disagreeable to the listening group. For this reason, pay careful attention to the carrying power or resonance of your voice.
The correct volume of the voice is determined by the place of meeting, the furnishings in the room, the size and construction of the walls and other factors affecting the transmission of the sound. Therefore, you must learn to determine the influence of these factors in order to gauge correctly the best volume for particular time and place.
When you are engaged in ordinary conversation or speaking to a group in a small room you must reduce the carrying power of your voice but, in places where the area is larger or wider, you must speak loudly enough to be heard but not so loud as to shout. You must be heard by every member of your audience.
Develop Resonance in Your Voice
Resonance amplifies the fundamental tone of the voice and enriches it by adding over tones or partial tones. Resonance improves the sound of the voice.
However, oftentimes, we do not take full advantage of the resonating chamber to make the voice more beautiful or we use the wrong ones because of habit or a physical abnormality. For example, if we allow too much of the vocal air stream to pass through the nose, a disconcerting nasality results. On the other hand, if we fail to allow the nasal cavities to resonate "m" and "n" sounds, a "cold-in-the head" quality characterizes our voice. As the liquid sounds are the chief carriers of resonance, we must learn to hold on to them, building up the tone by permitting them to endure for a number of seconds. See how much "golden" sound when we say "go-o-l-l--de-e-n-n" rather than "g'ld'n."
If the resonators (throat and mouth chambers) are not properly shaped, the voice that comes out is of poor quality - weak, thin, and unpleasant to the ear.
Humming is one of the best ways to attain beautiful resonance. Try humming until you feel the vibrations response in your lips, nose, and the cavity behind your nose and chest. Do it often.
Learn to hum up and down the musical scale. This will help you get more variety in your voice and will sharpen your ears.
Direct your tones forward in your mouth. Tones that come from the throat are guttural; not beautifully resonant.
Practice saying with force and precision words that end in ING, such as sing, ding, wing, ring, and bring.
