- The reason is because you will have to learn to breathe with the support of your diaphragm.
You may think you are breathing properly and question the above statement. If you are part of the majority, however – and that consists of 99% of the population – I can tell you in no uncertain terms, that you are using only your upper chest to breathe.
To discover your real voice – the one you don't know exists inside of you – you will have to use your chest cavity as your primary sounding board or primary amplifier. And, for that condition to be met, you must be breathing with support.
We are renowned for being lazy or shallow breathers. What this means when it comes to the voice is that we are using only 4 of our 5 vocal resonators to power our sound: the cavities of the voice box, throat, mouth and nose. The results are voices that tend to be higher in pitch, thinner in quality, young-sounding, possibly nasal, and most definitely not rich, warm nor resonant.
- Only when you can power your voice with your 5th resonator, your chest cavity, will you actually find the voice you don't know you have.
Once you have established diaphragmatic breathing, you will then discover numerous benefits that have nothing to do with your voice. From better sleep to improved physical endurance, from the lowering of your blood pressure to the elimination of much of the stress in your life. And, if nervousness is a problem for you in public speaking, you are in luck. Deep, supported breathing is the most effective means for controlling those nervous jitters. It works every time!
If you are looking for a course to improve the sound of your speaking voice, make sure that diaphragmatic breathing is the first priority in what that course may offer. Bear in mind, the majority of voice improvement courses do not stress this type of breathing and are essentially working with the voice you already have. Those who teach voice improvement by means of deep, supported breathing, are going to show you the voice you don't know you have.
