Velopharyngeal consonant

Velopharyngeal consonant is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Velopharyngeal consonant rather than just read about it. In short: The velopharyngeal fricatives, also known as the posterior nasal fricatives, are a family of sounds produced principally by people with a cleft palate, as substitutes for sibilants (which in English are /s, z, ʃ, ʒ, tʃ, dʒ, tr, dr/). These are "the so-called 'nasal snort', in which (usually loud) friction results from leakage through a tense, but incompletely occluded, velopharyngeal port," and results from "the app…

Key takeaways

Velopharyngeal consonant belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Velopharyngeal consonant to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Velopharyngeal consonant from memory before moving on to harder problems.

Reference excerpt

The velopharyngeal fricatives, also known as the posterior nasal fricatives, are a family of sounds produced principally by people with a cleft palate, as substitutes for sibilants (which in English are /s, z, ʃ, ʒ, tʃ, dʒ, tr, dr/). These are "the so-called 'nasal snort', in which (usually loud) friction results from leakage through a tense, but incompletely occluded, velopharyngeal port," and results from "the approximation but inadequate closure of the upper border of the velum and the posterior pharyngeal wall." To produce a velopharyngeal fricative, the soft palate approaches the pharyngeal wall and narrows the velopharyngeal port, such that the restricted port creates fricative turbulence in air forced through it into the nasal cavity. The articulation may be aided by a posterior positioning of the tongue and may involve velar flutter (a snorting sound). The term 'velopharyngeal' indicates "articulation between the upper surface of the velum and the back wall of the naso-pharynx." The base symbol for a velopharyngeal fricative in the extensions to the International Phonetic Alphabet for disordered speech is ⟨ʩ⟩, and secondary articulation is indicated with a superscript [𐞐]. The following variants are described:

A voiceless velopharyngeal fricative [ʩ] A voiced velopharyngeal fricative [ʩ̬] A velopharyngeal fricative trill or "snort" (much as epiglottal fricatives tend to be trilled): voiceless [𝼀] voiced [𝼀̬] Other consonants accompanied by velopharyngeal frication, such as [s𐞐], potentially transcribed ⟨s𐞐𐞪⟩ to overtly indicate accompanying trill.

The letter [𝼀] for the trill was only adopted in 2015; before then the letter ⟨ʩ⟩ had stood for both. Some authorities describe the trilled velopharyngeals as being accompanied by uvular trill rather than velar flutter. Whether this is a difference in interpretation or of pronunciation, it would be explicitly transcribed with a superscript ⟨ʀ⟩: voiceless [ʩ𐞪] and voiced [ʩ̬𐞪].

Worked examples

Example 1 — a first encounter with Velopharyngeal consonant

Start with the simplest possible case. Write down what Velopharyngeal consonant claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Velopharyngeal consonant before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Velopharyngeal consonant ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Velopharyngeal consonant

In research: Velopharyngeal consonant appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Velopharyngeal consonant in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Velopharyngeal consonant is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fricative consonants, Nasal consonants, Phonetics stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Velopharyngeal consonant outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
