Vocal tract

from Wikipedia, the free encyclopedia
Sagittal section of the human vocal tract

The vocal tract , also the neck tube (analogous to the neck tube of wind instruments ), articulation tract or speaking tract , is the supraglottal part of the speech apparatus, i.e. above the larynx .

It can be divided into three rooms or caves: the throat ( pharynx ), mouth ( oral cavity ) and nasal cavity ( nasal cavity ). The volume of both the former is variable due to the movement of the tongue , which results in a variable resonance space for individual sounds. The nasal cavity, on the other hand, is unchangeable in volume, but still participates in the formation of resonance. In addition to the tongue, the lips , teeth , roof of the mouth , soft palate and uvula also belong to the vocal tract.

The speaking apparatus in its present form in modern humans is around 150,000 years old. Its function is divided into two components, that of sound production and that of sound shaping.
