The laryngeal ventricle from a musical perspective

The vocal fold is in the thyroid cartilage, and the five resonance chambers are in the laryngeal ventricle.
A resonance chamber is actually very small, and located between the vocal fold and the vestibular fold(false vocal cord). This primary place determines the sound of the voice.
The shape of the thyroid cartilage differs greatly between individuals. These differences can be overall size, shape width (obtuse), and density.
The individual variability of the thyroid cartilage affects the shape of the laryngeal ventricle which in turn changes sound ability.
In my personal opinion, if the thyroid cartilage is big and wide, then the vocal fold is short. The space of the vocal fold would be large, giving the advantage of being able to let out a voice capable of both the high-register and low-register ranges.


Note:The resonance chamber is close to the vocal folds 1:laryngeal ventricle 2: piriform recess 3:pharyngeal cavity 4:oral cavity 5:nasal cavity.
The voice cannot be generated without airflow.
