Pre-voicing

Pre-voicing 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 Pre-voicing rather than just read about it. In short: Prevoicing, in phonetics, is voicing before the onset of a consonant or beginning with the onset of the consonant but ending before its release. In the extensions to the International Phonetic Alphabet for speech pathology, prevoicing is transcribed with a voicing diacritic ( ̬, U+032C) placed in front of the consonant, as in [ ̬d].

Key takeaways

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

Reference excerpt

Prevoicing, in phonetics, is voicing before the onset of a consonant or beginning with the onset of the consonant but ending before its release. In the extensions to the International Phonetic Alphabet for speech pathology, prevoicing is transcribed with a voicing diacritic ( ̬, U+032C) placed in front of the consonant, as in [ ̬d]. In several Khoisan languages of Southern Africa, such as Taa and !Kung, stops such as /dzʰ/ ([dsʰ] or [dtsʰ]) and /dzʼ/ ([dsʼ] or [dtsʼ]) are sometimes analyzed as being prevoiced / ̬tsʰ/ and / ̬tsʼ/, though the cessation of voicing has also been analyzed as phonetic detail in the transition of a phonemically voiced consonant to its voiceless aspiration or ejection. (See aspirated voiced consonant and voiced ejective.) Kelabit has a similar set of aspirated voiced consonants. Not all speakers produce the aspiration, resulting in prevoiced (or mixed voiced) [b͡p, d͡t, ɡ͡k] (or equivalently [ ̬p, ̬t, ̬k], and neighboring Lun Dayeh has [b͡p, d͡tʃ, ɡ͡k] (= [ ̬p, ̬tʃ, ̬k].

Worked examples

Example 1 — a first encounter with Pre-voicing

Start with the simplest possible case. Write down what Pre-voicing 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 Pre-voicing 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 Pre-voicing 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 Pre-voicing

In research: Pre-voicing 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 Pre-voicing 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: Pre-voicing is common in secondary-school and first-year university syllabi. It links to neighbouring topics Phonetics, Phonetics stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Pre-voicing 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.

Frequently asked questions

What is Pre-voicing in simple terms?

Why does Pre-voicing matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Pre-voicing?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
