AnatomyLearn About the anatomy of voice production
Voice production is divided into three major categories:
Your power source is the breath that supports your sound. This is the driving force, and anything that affects your breath (or your lungs) can completely eliminate your ability to produce sound.
Vibration of your true vocal folds causes vibrations in the air that your lungs have just generated and your abdominal muscles have pushed. The complex anatomy of the vocal folds is designed to produce smooth, even vibrations which will sound pleasant and not hoarse.
Resonators give all the richness and tone that make the voice musical and give it its individual quality and character.
Asthmatics are particularly aware of this but even non-asthmatics can understand this concept. Take a shallow breath and attempt to shout. Now, take a deeper breath and attempt to shout. Clearly it is easier with a deeper breath. Without enough air to support your sound, it will fall flat and quiet.
Your breath is driven by several factors:
- Your lungs
- Your diaphragm expansion
- Your abdominal support
Your lungs must be healthy in order to produce the breath you need. Managing any lung disease correctly will improve your voice.
Your diaphragm is the muscle that contracts to help expand your lungs. A slow, deep breath will give you more breath to work with. You can use this breath to produce a low-volume, long-duration sound or project a loud sound for a shorter amount of time.
Careful control of your abdominal muscles will allow you to push more or less air, in accordance with the sound you want to produce.
