Examples
A prenasalized stop starts out with a lowered velum that raises during the occlusion.
In disordered speech there are also velo-dorsal stops, with the opposite articulation: The velum lowers to contact the tongue, which remains static.
Therefore, although not all languages have been investigated on this point, phoneticians have recently come to use the term lingual (made with the tongue) as being more accurate for this airstream mechanism than velaric (made at the velum).
These species may be arranged into the variety, cumulus radiatus; and may be accompanied by up to seven supplementary features, cumulus pileus, velum, virga, praecipitatio, arcus, pannus, and tuba.
The upper or aboral surface is called the exumbrella and the lower surface is called the subumbrella; the mouth is located on the lower surface, which may be partially closed by a membrane extending inward from the margin (called the velum).
Velodorsal consonants Normal velar consonants are dorso-velar: The dorsum (body) of the tongue rises to contact the velum (soft palate) of the roof of the mouth.
