Nasal consonant in the context of "Labial consonant"

In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract, except for [h], which is pronounced without any stricture in the vocal tract. Examples are [p] and [b], pronounced with the lips; [t] and [d], pronounced with the front of the tongue; [k] and [g], pronounced with the back of the tongue; [h], pronounced throughout the vocal tract; [f], [v], [s], and [z] pronounced by forcing air through a narrow channel (fricatives); and [m] and [n], which have air flowing through the nose (nasals). Most consonants are pulmonic, using air pressure from the lungs to generate a sound. Very few natural languages are non-pulmonic, making use of ejectives, implosives, and clicks. Contrasting with consonants are vowels.

Since the number of speech sounds in the world's languages is much greater than the number of letters in any one alphabet, linguists have devised systems such as the International Phonetic Alphabet (IPA) to assign a unique and unambiguous symbol to each attested consonant. The English alphabet has fewer consonant letters than the English language has consonant sounds, so digraphs like ⟨ch⟩, ⟨sh⟩, ⟨th⟩, and ⟨ng⟩ are used to extend the alphabet, though some letters and digraphs represent more than one consonant. For example, the sound spelled ⟨th⟩ in "this" is a different consonant from the ⟨th⟩ sound in "thin". (In the IPA, these are [ð] and [θ], respectively.)

A syllabic consonant, or vocalic consonant, is a consonant that forms the nucleus of a syllable on its own, like the m, n and l in some pronunciations of the English words rhythm, button and awful, respectively. To represent it, the understroke diacritic in the International Phonetic Alphabet is used, ⟨U+0329 ◌̩ COMBINING VERTICAL LINE BELOW⟩. It may be instead represented by an overstroke, ⟨U+030D ◌̍ COMBINING VERTICAL LINE ABOVE⟩ if the symbol that it modifies has a descender, such as in [ŋ̍].

Syllabic consonants in most languages are sonorants, such as nasals and liquids. Very few have syllabic obstruents (i.e., stops, fricatives, and affricates) in normal words, but English has syllabic fricatives in paralinguistic words like shh! and zzz.

A nasal vowel is a vowel that is produced with a lowering of the soft palate (or velum) so that the air flow escapes through the nose and the mouth simultaneously, as in the French vowel /ɑ̃/ () or Amoy [ɛ̃]. By contrast, oral vowels are produced without nasalization.

Nasalized vowels are vowels influenced by nearby sounds. For instance, the [æ] of the word hand in English is affected by the following nasal consonant. In most languages, vowels adjacent to nasal consonants are produced partially or fully with a lowered velum in a natural process of assimilation and are therefore technically nasal, but few speakers would notice. That is the case in English: vowels preceding nasal consonants are nasalized, but there is no phonemic distinction between nasal and oral vowels, and all vowels are considered phonemically oral.

A voiced alveolar nasal is a type of consonantal sound used in numerous spoken languages. The symbol in the International Phonetic Alphabet that represents dental, alveolar, and postalveolar nasals is ⟨n⟩.

The vast majority of languages have either an alveolar or dental nasal. There are a few languages that lack either sound but have [m], such as Yoruba, Palauan, and colloquial Samoan (however, these languages all have [ŋ]. An example of a language without [n] and [ŋ] is Edo). There are some languages (e.g. Rotokas) that lack both [m] and [n].

Midland American English is a regional dialect or supradialect of American English, geographically lying between the traditionally defined Northern and Southern United States. The boundaries of Midland American English are not entirely clear, being revised and reduced by linguists due to definitional changes and several Midland sub-regions undergoing rapid and diverging pronunciation shifts since the early-middle 20th century onwards.

As of the early 21st century, these general characteristics of the Midland regional accent are firmly established: fronting of the /oʊ/, /aʊ/, and /ʌ/ vowels occurs towards the center or even the front of the mouth; the cot–caught merger is neither fully completed nor fully absent; and short-a tensing evidently occurs strongest before nasal consonants. The currently documented core of the Midland dialect region spans from central Ohio at its eastern extreme to central Nebraska and Oklahoma City at its western extreme. Certain areas outside the core also clearly demonstrate a Midland accent, including Charleston, South Carolina; the Texan cities of Abilene, Austin, and Corpus Christi; and central and some areas of southern Florida.

In phonetics and phonology, a sonorant or resonant is a speech sound that is produced with continuous, non-turbulent airflow in the vocal tract; these are the manners of articulation that are most often voiced in the world's languages. Vowels are sonorants, as are semivowels like [j] and [w], nasal consonants like [m] and [n], and liquid consonants like [l] and [r]. This set of sounds contrasts with the obstruents (stops, affricates and fricatives).

For some authors, only the term resonant is used with this broader meaning, while sonorant is restricted to the consonantal subset—that is, nasals and liquids only, not vocoids (vowels and semivowels).

In historical linguistics, transphonologisation (also known as rephonologisation or cheshirisation, see below) is a type of sound change whereby a phonemic contrast that used to involve a certain feature X evolves in such a way that the contrast is preserved, yet becomes associated with a different feature Y.

For example, a language contrasting two words */sat/ vs. */san/ may evolve historically so that final consonants are dropped, yet the modern language preserves the contrast through the nature of the vowel, as in a pair /sa/ vs. /sã/. Such a situation would be described by saying that a former contrast between oral and nasal consonants has been transphonologised into a contrast between oral and nasal vowels.

In phonetics, an occlusive, sometimes known as a stop, is a consonant sound produced by occluding (i.e. blocking) airflow in the vocal tract, but not necessarily in the nasal tract. The duration of the block is the occlusion of the consonant. An occlusive may refer to one or more of the following, depending on the author:

• Stops, or more precisely, oral stops—also known as plosives—are oral occlusives, where the occlusion of the vocal tract stops all airflow—oral and nasal.

• Nasals, also known as nasal stops, are nasal occlusives, where occlusion of the vocal tract shifts the airflow to the nasal tract.

• Affricates such as English /tʃ/, /dʒ/ are partial occlusives. Typically stops and affricates are contrasted, but affricates are also described as stops with fricative release, contrasting with simple stops (= plosives).
• Implosives, in which the airstream differs from typical stops and affricates (no examples in English).
• Ejectives, with yet another airstream (no examples in English).
• Click consonants, such as the exclamation tsk! tsk! made when expressing reproach (often humorously) or pity, are double occlusives with yet a fourth airstream mechanism. They may be oral occlusives, nasals, affricates, or ejective.

Oral occlusive may mean any of the above apart from nasal occlusives, but typically means stop/plosive. Nasal occlusive may be used to distinguish the simple nasal sounds from other nasal consonants.
