The velopharyngeal port or velopharyngeal sphincter is the passage between the nasopharynx and the oropharynx. It is closed off by the soft palate and uvula against the rear pharyngeal wall during swallowing to prevent food and water from entering the nasal passages. During speech, it is open for nasal sounds and closed for oral
Velopharyngeal insufficiency is a disorder of structure that causes a failure of the velum (soft palate) to close against the posterior pharyngeal wall (back wall of the throat) during speech in order to close off the nasal cavity during oral speech production.
Velopharyngeal insufficiency or incompetency are related labels for this phenomenon, in addition to most common generic- velopharyngeal inadequacy. Velopharyngeal insufficiency is the inability of the velopharyngeal sphincter to sufficiently separate the nasal cavity from the oral cavity during speech .
The velopharyngeal fricatives, also known as the posterior nasal fricatives, are a family of sounds produced by some children with speech disorders, including some with a cleft palate, as a substitute for sibilants (in English, /s, z, ʃ, ʒ, tʃ, dʒ, tr, dr/), which cannot be produced with a cleft palate. It results from "the approximation ...

Posterior pharyngeal flap surgery is the most commonly used operation to restore velopharyngeal competence (i.e., develop a functional seal between the vocal and the oral cavity), and therefore correct hypernasality and nasal air escape (Ysunza et al., 2002).
The turbulence in the airflow characteristic of fricatives is produced not in the mouth but at the anterior nasal port, the narrowest part of the nasal cavity. (Turbulence can also be produced at the posterior nasal port, or velopharyngeal port, when that port is narrowed – see velopharyngeal fricative. With anterior nasal fricatives, the ...
