Velar consonant
View on WikipediaVelar consonants are consonants articulated with the back part of the tongue (the dorsum) against the soft palate, the back part of the roof of the mouth (also known as the "velum").
Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum are not very precise, velars easily undergo assimilation, shifting their articulation back or to the front depending on the quality of adjacent vowels.[1] They often become automatically fronted, that is partly or completely palatal before a following front vowel, and retracted, that is partly or completely uvular before back vowels.
Palatalised velars (like English /k/ in keen or cube) are sometimes referred to as palatovelars. Many languages also have labialized velars, such as [kʷ], in which the articulation is accompanied by rounding of the lips. There are also labial–velar consonants, which are doubly articulated at the velum and at the lips, such as [k͡p]. This distinction disappears with the approximant consonant [w] since labialization involves adding of a labial approximant articulation to a sound, and this ambiguous situation is often called labiovelar.
A velar trill or tap is not possible according to the International Phonetics Association: see the shaded boxes on the table of pulmonic consonants. In the velar position, the tongue has an extremely restricted ability to carry out the type of motion associated with trills or taps, and the body of the tongue has no freedom to move quickly enough to produce a velar trill or flap.[2]

Lack of velars
[edit]The only languages recorded to lack velars (and any dorsal consonant at all) may be Xavante, standard Tahitian (though /tVt/ is pronounced [kVt], a pattern also found in the Niihau dialect of Hawaiian), and arguably several Skou languages (Wutung, the Dumo dialect of Vanimo, and Bobe), which have a coda [ŋ] that has been analyzed as the realization of nasal vowels. In Pirahã, men may lack the only velar consonant.
Other languages lack simple velars. An areal feature of the indigenous languages of the Americas of the coastal regions of the Pacific Northwest is that historical *k was palatalized. When such sounds remained stops, they were transcribed ⟨kʸ⟩ in Americanist phonetic notation, presumably corresponding to IPA ⟨c⟩, but in others, such as the Saanich dialect of Coastal Salish, Salish-Spokane-Kalispel, and Chemakum, *k went further and affricated to [tʃ]. Likewise, historical *k’ has become [tʃʼ] and historical *x has become [ʃ]; there was no *g or *ŋ. In the Northwest Caucasian languages, historical *[k] has also become palatalized, becoming /kʲ/ in Ubykh and /tʃ/ in most Circassian varieties. In both regions the languages retain a labialized velar series (e.g. [kʷ], [kʼʷ], [gʷ], [xʷ], [w] in the North Caucasus) as well as uvular consonants.[7] In the languages of those families that retain plain velars, both the plain and labialized velars are pre-velar, perhaps to make them more distinct from the uvulars which may be post-velar. Prevelar consonants are susceptible to palatalization. A similar system, contrasting *kʲ with *kʷ and leaving *k marginal at best, is reconstructed for Proto-Indo-European.
Apart from the voiceless plosive [k], no other velar consonant is particularly common, even the [w] and [ŋ] that occur in English. There can be no phoneme /ɡ/ in a language that lacks voiced stops, like Mandarin Chinese,[c] but it is sporadically missing elsewhere. Of the languages surveyed in the World Atlas of Language Structures, about 10% of languages that otherwise have /p b t d k/ are missing /ɡ/.[8]
Pirahã has both a [k] and a [ɡ] phonetically. However, the [k] does not behave as other consonants, and the argument has been made that it is phonemically /hi/, leaving Pirahã with only /ɡ/ as an underlyingly velar consonant.
Hawaiian does not distinguish [k] from [t]; ⟨k⟩ tends toward [k] at the beginning of utterances, [t] before [i], and is variable elsewhere, especially in the dialect of Niʻihau and Kauaʻi. Since Hawaiian has no [ŋ], and ⟨w⟩ varies between [w] and [v], it is not clearly meaningful to say that Hawaiian has phonemic velar consonants.
Several Khoisan languages have limited numbers or distributions of pulmonic velar consonants. (Their click consonants are articulated in the uvular or possibly velar region, but that occlusion is part of the airstream mechanism rather than the place of articulation of the consonant.) Khoekhoe, for example, does not allow velars in medial or final position, but in Juǀʼhoan velars are rare even in initial position.
Velodorsal consonants
[edit]Normal velar consonants are dorso-velar: The dorsum (body) of the tongue rises to contact the velum (soft palate) of the roof of the mouth. In disordered speech there are also velo-dorsal stops, with the opposite articulation: The velum lowers to contact the tongue, which remains static. In the extensions to the IPA for disordered speech, these are transcribed by reversing the IPA letter for a velar consonant, e.g. ⟨𝼃⟩ for a voiceless velodorsal stop,[d] ⟨𝼁⟩ for voiced, and ⟨𝼇⟩ for a nasal.

Definition
Velar consonants are a class of speech sounds produced by raising the back of the tongue, known as the dorsum, to make contact with or approach the soft palate, also called the velum, which forms the rear portion of the roof of the mouth.[1] This place of articulation sets velar consonants apart from those at other locations, such as bilabial consonants formed with the lips or alveolar consonants involving the tongue tip or blade near the alveolar ridge behind the upper teeth.[3] Velar consonants belong to the broader category of dorsal consonants, in which the dorsum serves as the primary active articulator.[8] The most common velar consonants are stops, including the voiceless velar stop and the voiced velar stop [ɡ].[9] The velum plays a key role not only in primary velar articulation but also in velarization, a secondary articulation where the back of the tongue is raised toward the velum while the primary constriction occurs elsewhere, as seen in sounds like the velarized alveolar lateral approximant [ɫ]. The term "velar" originates from the Latin word velum, meaning "veil" or "curtain," reflecting the soft palate's flexible, curtain-like anatomical structure.[10] This nomenclature was adopted in phonetics to describe articulations involving this region of the vocal tract.[11]Articulatory Phonetics
Velar consonants are produced by raising the dorsum of the tongue to make contact with the soft palate, or velum, typically at the midline of the vocal tract. This articulation creates a constriction or closure in the back of the oral cavity, distinguishing velars from more forward places like palatals or alveolars. The precise point of contact can vary along the velum: prevelar articulations occur more anteriorly, closer to the hard palate-soft palate junction, while postvelar ones are retracted toward the back of the velum, sometimes approaching uvular territory in certain languages. These variations reflect the relatively broad span of the velar region, allowing for subtle differences in tongue body positioning without altering the primary place classification.[12][13] In terms of airflow mechanics, velar stops involve a complete closure between the tongue dorsum and velum, blocking pulmonic egressive airflow through the oral cavity and building intraoral pressure behind the constriction. Upon release, this pressure is abruptly expelled in a characteristic velar plosion, producing a burst of noise as the articulators separate; the velum remains raised to prevent nasal airflow during this oral phase. For velar fricatives, the tongue dorsum approximates but does not fully contact the velum, creating a narrow channel that generates turbulent airflow and frictional noise due to the high-velocity air passing through the restricted back cavity. These aerodynamic patterns ensure that velars maintain their place-specific acoustic signatures, with stops featuring a momentary silence followed by release, and fricatives exhibiting continuous but noisy airflow.[12] Acoustically, velar consonants are marked by distinct formant transitions, particularly in the second formant (F2), which typically shows low values around 1000-1500 Hz during the consonant-vowel transition due to the resonance of the enlarged back cavity anterior to the velar constriction. For velar stops, F2 and F3 frequencies converge closely during the closure phase, reflecting the compact spectral structure from the velar pinch, while the release burst often displays diffuse high-frequency energy. These properties arise from the backward positioning of the tongue, which lengthens the front cavity and shortens the back one, leading to lower F2 loci compared to alveolar or labial consonants.[14] Individual differences in velar articulation are prominent, influenced by coarticulatory context and speaker anatomy; for instance, in English, the velar stop often fronts toward a prevelar position before front vowels like /i/, shifting the tongue contact anteriorly to accommodate the high tongue position of the vowel, while remaining more central or back before non-front vowels. This fronting reduces the perceptual distance to palatal-like articulations and varies across speakers based on vocal tract geometry, with some exhibiting greater advancement due to habitual patterns or dialectal norms. Such variations highlight the dynamic nature of velar production, where anatomical constraints and phonetic context modulate the exact locus without compromising the consonant's identity.[15]Phonological Features
Voiced and Voiceless Variants
Velar consonants exhibit a fundamental distinction between voiceless and voiced variants, primarily observed in stops where voicing determines the vibration of the vocal folds during the oral closure at the velum. Voiceless velar stops, such as , are articulated with the vocal folds held apart, preventing glottal vibration and resulting in a period of silence or voiceless airflow following the release. This variant is ubiquitous across languages and often appears in aspirated forms like [kʰ], where post-aspiration adds a burst of voiceless air, as in Hindi, with voice onset time (VOT) typically ranging from 80 to 100 ms for the aspirated realization.[16] In contrast, voiced velar stops, represented by , involve vibration of the vocal folds throughout the closure, producing periodic glottal pulses that contribute to the sound's resonance. These consonants frequently undergo lenition in intervocalic positions, weakening to approximants like [ɰ], a process driven by aerodynamic pressures that reduce articulatory effort while maintaining voicing. VOT for is generally negative (prevoicing) or short-lag (0-30 ms), distinguishing it acoustically from its voiceless counterpart and aiding perceptual categorization in languages like English.[17] Phonologically, the voice contrast between /k/ and /g/ serves as a key oppositional feature in many inventories, enabling minimal pairs such as "coat" versus "goat" in English, where the distinction relies on VOT differences—approximately 80-100 ms for /k/ versus negative values for /g/. This opposition is subject to rules like final devoicing in German, where underlying voiced obstruents, including /g/, surface as voiceless in syllable codas due to a phonological constraint neutralizing voicing word-finally.[18] Such patterns highlight how voicing interacts with prosodic structure, influencing both production and perception across languages.[19]Nasal and Other Manners
The velar nasal [ŋ] is articulated by raising the back of the tongue to contact the soft palate (velum), completely blocking the oral cavity, while the velum is lowered to direct airflow through the nasal passages.[20] This manner contrasts with oral stops by permitting nasal resonance, resulting in a voiced sound with sustained nasal airflow.[21] In many languages, including English, [ŋ] frequently appears as an allophone of the alveolar nasal /n/ in assimilation before velar consonants, as in the pronunciation of "ten kilometers" [tʰɛŋ kɪˈlɑmɪtərz] where /n/ assimilates in place to [ŋ].[22] Velar fricatives include the voiceless and voiced [ɣ], produced by narrowing the space between the tongue dorsum and velum to create turbulent airflow without full closure. The voiceless variant involves aspiration-like friction at the velar point, while [ɣ] adds vocal fold vibration for voicing. Uvular variants such as the voiceless [χ] are distinguished by a posterior articulation at the uvula rather than the velum, often occurring in languages with back consonant inventories and producing a raspier quality due to the shifted constriction. The velar approximant [ɰ] is a rare non-fricative manner, involving a loose approximation of the tongue dorsum to the velum that allows smooth airflow without turbulence or closure.[23] Similarly uncommon is the velar lateral approximant [ʟ], which features central tongue-velum contact or near-contact combined with lowered tongue sides to permit lateral airflow around the obstruction.[24] These approximants lack the intense friction of fricatives, emphasizing gliding transitions in vowel-like contexts. Phonetic realizations of velar manners often involve coarticulatory place shifts influenced by adjacent segments; for instance, the velar nasal [ŋ] may front or palatalize toward [ɲ] before front vowels due to anticipatory tongue raising.[25] Such variations enhance perceptual clarity in vowel-consonant sequences without altering the core velar identity.Representation and Examples
IPA Chart
The International Phonetic Alphabet (IPA) provides a standardized system for representing velar consonants, which are articulated with the back of the tongue against the soft palate (velum). The pulmonic consonants chart excerpt for the velar place of articulation includes symbols for common manners of articulation, organized by voicing where applicable. These symbols are derived from the official IPA chart maintained by the International Phonetic Association. The following table summarizes the pulmonic velar consonants:| Manner of Articulation | Voiceless | Voiced |
