Uvular complex in vouce

Uvular complex in voice production.

Acoustic theory of voice production, also known as the source-filter theory, explains how speech sounds are created by a combination of a sound source (like the vibrating vocal folds) and a filter (the vocal tract). The source generates the initial sound, and the vocal tract modifies it through resonance, shaping the sound into recognizable speech sounds. 

1. The Source:

Vocal Fold Vibration:

The primary source of sound for voiced sounds is the vibration of the vocal folds within the larynx. 

Aspiration:

For voiceless sounds, air rushing through a narrow opening, like in fricatives, creates a source of noise. 

Other Sources:

Other sources include transient sounds created during consonant production and turbulence during the airflow through the vocal tract. 

Clearly indicate that we can produce voice by the vibration of any structure in the vocal tract. We can create more vibration in the uvular complex. This is the theory behind treatment for puberphonia by UMAR.
