Voice quality is determined by each one's individual resonance system. By resonance, we mean transmission of sound and it's travels through various cavities and ports, (e.g. throat, mouth and nasal cavities), creating our individual sound that transcribes us as sounding like us.

The size and shape of our own individual cavities, enhances the sound transmitted from the larynx, or voice box. Changes within the cavities, change the quality of sound produced.


For instance, if a person were to hold the tongue in a tight position in the back portion of the mouth, the oral cavity would be changed in regards to size and shape.

Or if we cannot efficiently close off the nasal port as is designed to happen when producing vowel sounds and most consonants, unwanted nasalness would be added to our speech.

Creating changed space creates a reconfigured resonating chamber which results in sound quality changes. We automatically experience a change in space when we have a stuffy nose from a cold or experience allergies.

A balanced resonance system is desired where the throat, oral and nasal cavities are working in conjunction with one another. When dominance of one cavity occurs, quality changes are noted by the speaker and others.

Hypernasality occurs when too much sound is transmitted through the nasal cavity. The cause can be the result of structural abnormalites or by characteristic regional dialect or accent patterns.

Hyponasality occurs when the nasal cavity cannot be accessed for important nasal sounds, (m, n, ng). The speaker may sound as if they are saying babba for mama or badada for banana.

The Perfect Voice offers a free self-screening to help determine if you have a nasality problem.
