Labialization is a secondary articulatory feature of sounds in some languages. Labialized sounds involve the lips while the remainder of the oral cavity produces another sound. The term is normally restricted to consonants. When vowels involve the lips, they are called rounded.
The most common labialized consonants are labialized velars. Most other labialized sounds also have simultaneous velarization, and the process may then be more precisely called labio-velarization. The "labialization" of bilabial consonants often refers to protrusion instead of a secondary articulatory feature velarization. [pʷ] doesn't mean [pˠ] although [w] refers to a labial–velar approximant.
In phonology, labialization may also refer to a type of assimilation process.
Labialization is the most widespread secondary articulation in the world's languages. It is phonemically contrastive in Northwest Caucasian (e.g. Adyghe), Athabaskan, and Salishan language families, among others. This contrast is reconstructed also for Proto-Indo-European, the common ancestor of the Indo-European languages; and it survives in Latin and some Romance languages. It is also found in the Cushitic and Ethio-Semitic languages.
American English labializes /r,ʃ,ʒ,tʃ,dʒ/ to various degrees.[ citation needed ]
A few languages, including Arrernte and Mba, have contrastive labialized forms for almost all of their consonants.
In many Salishan languages, such as Klallam, velar consonants only occur in their labialized forms (except /k/, which occurs in some loanwords). However, uvular consonants occur abundantly labialized and unrounded.

Out of 706 language inventories surveyed by Ruhlen (1976), labialization occurred most often with velar (42%) and uvular (15%) segments and least often with dental and alveolar segments. With non-dorsal consonants, labialization may include velarization as well. Labialization is not restricted to lip-rounding. The following articulations have either been described as labialization or been found as allophonic realizations of prototypical labialization:
Eastern Arrernte has labialization at all places and manners of articulation; this derives historically from adjacent rounded vowels, as is also the case of the Northwest Caucasian languages. Marshallese also has phonemic labialization as a secondary articulation at all places of articulation except for labial consonants and coronal obstruents.
In North America, languages from a number of families have sounds that sound labialized (and vowels that sound rounded) without the participation of the lips. See Tillamook language for an example.
In Slovene, sounds can be prelabialized. Furthermore, the change is phonemic and all phonemes have prelabialized pairs (though not all of their allophones can have pairs). Compare stati 'stand' [ˈs̪t̪àːt̪í] and vstati 'stand up' [ˈʷs̪t̪àːt̪í]. The prelabialization part, however, is usually not considered as being part of the same phoneme as prelabialized sound, but rather as an allophone of /ʋ/ as it changes depending on the environment, e. g. vzeti 'take' [ˈʷz̪èːt̪í] and povzeti 'summarize' [pou̯ˈz̪èːt̪í]. [2] See Slovene phonology for more details.
In the International Phonetic Alphabet, labialization of velar consonants is indicated with a raised w modifier [ʷ] (Unicode U+02B7), as in /kʷ/. (Elsewhere this diacritic generally indicates simultaneous labialization and velarization.[ citation needed ]) There are also diacritics, respectively [ɔ̹],[ɔ̜], to indicate greater or lesser degrees of rounding. [3] These are normally used with vowels but may occur with consonants. For example, in the Athabaskan language Hupa, voiceless velar fricatives distinguish three degrees of labialization, transcribed either /x/,/x̹/,/xʷ/ or /x/,/x̜ʷ/,/xʷ/.
The extensions to the IPA has two additional symbols for degrees of rounding: Spread [ɹ͍] and open-rounded [ʒꟹ] (as in English). It also has a symbol for labiodentalized sounds, [tᶹ]. [4]
If precision is desired, the Abkhaz and Ubykh articulations may be transcribed with the appropriate fricative or trill raised as a diacritic: [tᵛ], [tᵝ], [tʙ], [tᵖ].
For simple labialization, Ladefoged & Maddieson (1996) resurrected an old IPA symbol, [ ̫], [5] which would be placed above a letter with a descender such as ɡ. However, their chief example is Shona sv and zv, which they transcribe /s̫/ and /z̫/ but which actually seem to be whistled sibilants, without necessarily being labialized. [6] Another possibility is to use the IPA diacritic for rounding, distinguishing for example the labialization in English soon[s̹] and [sʷ]swoon. [7] The open rounding of English /ʃ/ is also unvelarized.
Labialization also refers to a specific type of assimilatory process where a given sound become labialized due to the influence of neighboring labial sounds. For example, /k/ may become /kʷ/ in the environment of /o/, or /a/ may become /o/ in the environment of /p/ or /kʷ/.
In the Northwest Caucasian languages as well as some Australian languages rounding has shifted from the vowels to the consonants, producing a wide range of labialized consonants and leaving in some cases only two phonemic vowels. This appears to have been the case in Ubykh and Eastern Arrernte, for example. The labial vowel sounds usually still remain, but only as allophones next to the now-labial consonant sounds.
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract, except for the h sound, which is pronounced without any stricture in the vocal tract. Examples are and [b], pronounced with the lips; and [d], pronounced with the front of the tongue; and [g], pronounced with the back of the tongue;, pronounced throughout the vocal tract;, [v], and, pronounced by forcing air through a narrow channel (fricatives); and and, 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.
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators, and translators.
In articulatory phonetics, the place of articulation of a consonant is an approximate location along the vocal tract where its production occurs. It is a point where a constriction is made between an active and a passive articulator. Active articulators are organs capable of voluntary movement which create the constriction, while passive articulators are so called because they are normally fixed and are the parts with which an active articulator makes contact. Along with the manner of articulation and phonation, the place of articulation gives the consonant its distinctive sound.
Velars are consonants articulated with the back part of the tongue against the soft palate, the back part of the roof of the mouth.
Ubykh, an extinct Northwest Caucasian language, has the largest consonant inventory of all documented languages that do not use clicks, and also has the most disproportional ratio of phonemic consonants to vowels. It has consonants in at least eight, perhaps nine, basic places of articulation and 29 distinct fricatives, 27 sibilants, and 20 uvulars, more than any other documented language. Some Khoisan languages, such as Taa, may have larger consonant inventories due to their extensive use of click consonants, although some analyses view a large proportion of the clicks in these languages as clusters, which would bring them closer into line with the Caucasian languages.
A labialized velar or labiovelar is a velar consonant that is labialized, with a -like secondary articulation. Examples are, which are pronounced like a, with rounded lips, such as the labialized voiceless velar plosive and labialized voiced velar plosive, obstruents being common among the sounds that undergo labialization.
In phonetics, palatalization or palatization is a way of pronouncing a consonant in which part of the tongue is moved close to the hard palate. Consonants pronounced this way are said to be palatalized and are transcribed in the International Phonetic Alphabet by affixing the letter ⟨ʲ⟩ to the base consonant. Palatalization is not phonemic in English, but it is in Slavic languages such as Russian and Ukrainian, Finnic languages such as Estonian and Võro, as well as in other languages such as Irish, Marshallese, and Kashmiri.
Pharyngealization is a secondary articulation of consonants or vowels by which the pharynx or epiglottis is constricted during the articulation of the sound.
In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with aspirated, voiced and tenuis consonants. Some languages have glottalized sonorants with creaky voice that pattern with ejectives phonologically, and other languages have ejectives that pattern with implosives, which has led to phonologists positing a phonological class of glottalic consonants, which includes ejectives.
The voiced labiodental nasal is a type of consonantal sound. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɱ⟩. The IPA symbol is a lowercase letter m with a leftward hook protruding from the lower right of the letter. Occasionally it is instead transcribed as an with a dental diacritic: ⟨m̪⟩.
The voiced palatal approximant is a type of consonant used in many spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨j⟩. The equivalent X-SAMPA symbol is j
, and in the Americanist phonetic notation it is ⟨y⟩. Because the English name of the letter J, jay, starts with, the approximant is sometimes instead called yod (jod), as in the phonological history terms yod-dropping and yod-coalescence.
In phonetics, vowel roundedness is the amount of rounding in the lips during the articulation of a vowel. It is labialization of a vowel. When a rounded vowel is pronounced, the lips form a circular opening, and unrounded vowels are pronounced with the lips relaxed. In most languages, front vowels tend to be unrounded, and back vowels tend to be rounded. However, some languages, such as French, German and Icelandic, distinguish rounded and unrounded front vowels of the same height, and Vietnamese distinguishes rounded and unrounded back vowels of the same height. Alekano has only unrounded vowels. In the International Phonetic Alphabet vowel chart, rounded vowels are the ones that appear on the right in each pair of vowels. There are also diacritics, U+0339◌̹COMBINING RIGHT HALF RING BELOW and U+031C◌̜COMBINING LEFT HALF RING BELOW, to indicate greater and lesser degrees of rounding, respectively. Thus has less rounding than cardinal, and has more. These diacritics can also be used with unrounded vowels: is more spread than cardinal, and is less spread than cardinal.
The sj-sound is a voiceless fricative phoneme found in the sound system of most dialects of Swedish. It has a variety of realisations, whose precise phonetic characterisation is a matter of debate, but which usually feature distinct labialization. The sound is represented in Swedish orthography by a number of spellings, including the digraph ⟨sj⟩ from which the common Swedish name for the sound is derived, as well as ⟨stj⟩, ⟨skj⟩, and ⟨sk⟩. The sound should not be confused with the Swedish tj-sound, often spelled ⟨tj⟩, ⟨kj⟩, or ⟨k⟩.
Velarization or velarisation is a secondary articulation of consonants by which the back of the tongue is raised toward the velum during the articulation of the consonant. In the International Phonetic Alphabet, velarization is transcribed by one of four diacritics:
Doubly articulated consonants are consonants with two simultaneous primary places of articulation of the same manner. They are a subset of co-articulated consonants. They are to be distinguished from co-articulated consonants with secondary articulation; that is, a second articulation not of the same manner. An example of a doubly articulated consonant is the voiceless labial–velar plosive, which is a and a pronounced simultaneously. On the other hand, the voiceless labialized velar plosive has only a single stop articulation, velar, with a simultaneous approximant-like rounding of the lips. In some dialects of Arabic, the voiceless velar fricative has a simultaneous uvular trill, but this is not considered double articulation either.
A labial–coronal consonant is a consonant produced with two simultaneous articulators: with the lips, and with the tongue.
In phonetics, secondary articulation occurs when the articulation of a consonant is equivalent to the combined articulations of two or three simpler consonants, at least one of which is an approximant. The secondary articulation of such co-articulated consonants is the approximant-like articulation. It "colors" the primary articulation rather than obscuring it. Maledo (2011) defines secondary articulation as the superimposition of lesser stricture upon a primary articulation.
Abkhaz is a language of the Northwest Caucasian family which, like the other Northwest Caucasian languages, is very rich in consonants. Abkhaz has a large consonantal inventory that contrasts 58 consonants in the literary Abzhywa dialect, coupled with just two phonemic vowels.
In phonetics and phonology, relative articulation is description of the manner and place of articulation of a speech sound relative to some reference point. Typically, the comparison is made with a default, unmarked articulation of the same phoneme in a neutral sound environment. For example, the English velar consonant is fronted before the vowel compared to articulation of before other vowels. This fronting is called palatalization.
The voiceless bilabial trill is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʙ̥⟩. The X-SAMPA symbol is B\_0
