One can hardly ignore the loud voice of a newborn baby: with no warm-ups, training or instruction, he uses his vocal folds correctly, controlling them so perfectly, as to produce ear-piercing sounds with significant vocal strength.
This shows that speaking and even (non-professional) singing are innate skills, which require no training. Professional help is only needed in case your vocal effect is unsatisfactory.
In other words, natural, free, and fluent singing or speech comes easy. But in order to achieve vocal strength you must, sometimes, contract your oral cavity and neck muscles-without a further straining of your cords, but while relaxing them.
Confusing as it may sound, it’s very easy to practice these techniques for improving vocal strength.
Supposing you had a strong voice, as a baby, you have the same vocal capacity today-unless your lifestyle is unhealthy.
So, if you’re not heard loud and clear, or you have difficulties to generate a strong sound effortlessly or without damaging your voice, you should try the following exercises:
Warning: in case of ailments on your vocal cords, of vocal fatigue, avoid these exercises. Instead, perform short relaxation exercises such as the drinking straw exercise
The purpose of his exercise is tightening your belly and diaphragm, strengthening the breath support and make the diaphragm and abdominal muscles contract with a better coordination. This allows you to support and strengthen your voice. We recommend performing this exercise a few seconds before any vocal effort.
Practically speaking, just imagine your upper and lower teeth forcefully attached together while speaking or singing. This should increase your vocal volume and enhance local muscles effect. To increase the effect, you may show your teeth occasionally.
Another and commonly practices vocal strength exercise is trying to speak while holding a cork with your teeth. This exercise stresses actions such as, biting, small mouth opening, and teeth exposing. It also uses additional force of external neck muscles during consonant pronunciation and increases air resistance, thus pushing the vocal folds more tightly against each other, eventually producing a stronger voice.
When shouting or singing high tones, as well as low tones, (tones above or below first octave), we recommend you should relax your lower jaw. Here, the extent of mouth opening is most important: in high and low tones, a wide mouth opening strains the muscles which allow the tightening of you vocal cords. This makes it easier for you to reach high and low tones. When singing the middle octave, you should not open your mouth widely. By contrast, when singing very high tones, you should release your upper jaw further, smile wide, and sense your voice vibrating with head resonance. This exercise should strengthen your voice box muscles and boost your confidence.
