Фрикатив артикуляторов - это согласный , созданный путем затягивания воздуха через узкий канал, изготовленный путем размещения двух близко друг к другу. ^{[ 1 ]} Это может быть нижняя губа на верхних зубах, в случае [F] ; Задняя часть языка против мягкого неба в случае немецкого [x] (окончательный согласный Баха ); или сторона языка против моляров , в случае валлийца [ɬ] (дважды появляясь в названии Llanelli ). Этот турбулентный воздушный поток называется фрикацией . ^{[ 2 ]}

Определенная подмножество фрикативных - это сибиланты . При формировании сибиланта один все еще заставляет воздух через узкий канал, но, кроме того, язык свергается вдоль, чтобы направить воздух над краем зубов. ^{[ 1 ]} Английский [s] , [z] , [ʃ] и [ʒ] являются примерами сибилантов.

Использование двух других терминов менее стандартизировано: « спирирующий »-это более старый термин для фрикативных, используемых некоторыми американскими и европейскими фонетиками и фонологами для не-сибиландеров. ^{[ 3 ]} « Строго » может означать просто «сибилант», но некоторые авторы ^{[ ВОЗ? ]} Включите также лабиодиентные и UVular Fricative в класс.

Типы

Поток воздуха не полностью остановлен в производстве фрикативных согласных. Другими словами, воздушный поток испытывает трение .

Sibilants

[s] voiceless coronal sibilant, as in English sip
[z] voiced coronal sibilant, as in English zip
- [s̪] voiceless dental sibilant
- [z̪] voiced dental sibilant
- [s̺] voiceless apical sibilant
- [z̺] voiced apical sibilant
- [s̟] voiceless predorsal sibilant (laminal, with tongue tip at lower teeth)^[4]
- [z̟] voiced predorsal sibilant (laminal)
- [s̠] voiceless postalveolar sibilant (laminal)
- [z̠] voiced postalveolar sibilant (laminal)
[ʃ] voiceless palato-alveolar sibilant (domed, partially palatalized), as in English ship
[ʒ] voiced palato-alveolar sibilant (domed, partially palatalized), as the si in English vision
[ɕ] voiceless alveolo-palatal sibilant (laminal, palatalized)
[ʑ] voiced alveolo-palatal sibilant (laminal, palatalized)
[ʂ] voiceless retroflex sibilant (apical or subapical)
[ʐ] voiced retroflex sibilant (apical or subapical)

All sibilants are coronal, but may be dental, alveolar, postalveolar, or palatal (retroflex) within that range. However, at the postalveolar place of articulation, the tongue may take several shapes: domed, laminal, or apical, and each of these is given a separate symbol and a separate name. Prototypical retroflexes are subapical and palatal, but they are usually written with the same symbol as the apical postalveolars. The alveolars and dentals may also be either apical or laminal, but this difference is indicated with diacritics rather than with separate symbols.

Central non-sibilant fricatives

[ɸ] voiceless bilabial fricative
[β] voiced bilabial fricative
[f] voiceless labiodental fricative, as in English fine
[v] voiced labiodental fricative, as in English vine
[θ̼] voiceless linguolabial fricative
[ð̼] voiced linguolabial fricative
[θ], [θ̟] voiceless dental non-sibilant fricative, as in English thing
[ð], [ð̟] voiced dental non-sibilant fricative, as in English that
[θ̠], [ɹ̝̊] voiceless alveolar non-sibilant fricative
[ð̠], [ɹ̝] voiced alveolar non-sibilant fricative
[r̝̊] Voiceless alveolar fricative trill
[r̝] Voiced alveolar fricative trill
[ç] voiceless palatal fricative
[ʝ] voiced palatal fricative
[x] voiceless velar fricative
[ɣ] voiced velar fricative
[ɧ] voiceless palatal-velar fricative (articulation disputed)

The IPA also has letters for epiglottal fricatives,

[ʜ] voiceless epiglottal fricative
[ʢ] voiced epiglottal fricative

with allophonic trilling, but these might be better analyzed as pharyngeal trills. ^[5]

[ʩ] voiceless velopharyngeal fricative (often occurs with a cleft palate)
[ʩ̬] voiced velopharyngeal fricative

Lateral fricatives

[ɬ̪] voiceless dental lateral fricative
[ɮ̪] voiced dental lateral fricative
[ɬ] voiceless alveolar lateral fricative
[ɮ] voiced alveolar lateral fricative
[ɬ̠] voiceless postalveolar lateral fricative (Mehri)
[ɮ̠] voiced postalveolar lateral fricative
[ɭ˔̥] or extIPA [ꞎ] voiceless retroflex lateral fricative
[ɭ˔] or extIPA [𝼅] Voiced retroflex lateral fricative (in Ao)
[ʎ̥˔] or [ʎ̝̥] or extIPA [𝼆] voiceless palatal lateral fricative
[ʎ̝] or extIPA [𝼆̬] voiced palatal lateral fricative (allophonic in Jebero)
[ʟ̝̊] or extIPA [𝼄] voiceless velar lateral fricative
[ʟ̝] or extIPA [𝼄̬] voiced velar lateral fricative

The lateral fricative occurs as the ll of Welsh, as in Lloyd, Llewelyn, and Machynlleth ([maˈxənɬɛθ], a town), as the unvoiced 'hl' and voiced 'dl' or 'dhl' in the several languages of Southern Africa (such as Xhosa and Zulu), and in Mongolian.

ʪ or [ɬ͜s] and [θ͜ɬ] voiceless lateral-median fricative (a laterally lisped [s] or [θ]) (Modern South Arabian)
ʫ or [ɮ͜z] and [ð͜ɮ] voiced lateral-median fricative (a laterally lisped [z] or [ð]) (Modern South Arabian)

IPA letters used for both fricatives and approximants

No language distinguishes fricatives from approximants at these places, so the same symbol is used for both. For the pharyngeal, approximants are more numerous than fricatives. A fricative realization may be specified by adding the uptack to the letters, [χ̝, ʁ̝, ħ̝, ʕ̝]. Likewise, the downtack may be added to specify an approximant realization, [χ̞, ʁ̞, ħ̞, ʕ̞].

(The bilabial approximant and dental approximant do not have dedicated symbols either and are transcribed in a similar fashion: [β̞, ð̞]. However, the base letters are understood to specifically refer to the fricatives.)

Pseudo-fricatives

[h] voiceless glottal transition, as in English hat
[ɦ] breathy-voiced glottal transition

In many languages, such as English or Korean, the glottal "fricatives" are unaccompanied phonation states of the glottis, without any accompanying manner, fricative or otherwise. They may be mistaken for real glottal constrictions in a number of languages, such as Finnish.^[6]

In addition, [ʍ] is usually called a "voiceless labial-velar fricative", but it is actually an approximant. True doubly articulated fricatives may not occur in any language; but see voiceless palatal-velar fricative for a putative (and rather controversial) example.

Aspirated fricatives

Fricatives are very commonly voiced, though cross-linguistically voiced fricatives are not nearly as common as tenuis ("plain") fricatives. Other phonations are common in languages that have those phonations in their stop consonants. However, phonemically aspirated fricatives are rare. /s~sʰ/ contrasts with a tense, unaspirated /s͈/ in Korean; aspirated fricatives are also found in a few Sino-Tibetan languages, in some Oto-Manguean languages, in the Siouan language Ofo (/sʰ/ and /fʰ/), and in the (central?) Chumash languages (/sʰ/ and /ʃʰ/). The record may be Cone Tibetan, which has four contrastive aspirated fricatives: /sʰ/ /ɕʰ/, /ʂʰ/, and /xʰ/.^[7]

Nasalized fricatives

Phonemically nasalized fricatives are rare. Umbundu has /ṽ/ and Kwangali and Souletin Basque have /h̃/. In Coatzospan Mixtec, [β̃, ð̃, s̃, ʃ̃] appear allophonically before a nasal vowel, and in Igbo nasality is a feature of the syllable; when /f v s z ʃ ʒ/ occur in nasal syllables they are themselves nasalized.^[8]

Occurrence

Until its extinction, Ubykh may have been the language with the most fricatives (29 not including /h/), some of which did not have dedicated symbols or diacritics in the IPA. This number actually outstrips the number of all consonants in English (which has 24 consonants). By contrast, approximately 8.7% of the world's languages have no phonemic fricatives at all.^[9] This is a typical feature of Australian Aboriginal languages, where the few fricatives that exist result from changes to plosives or approximants, but also occurs in some indigenous languages of New Guinea and South America that have especially small numbers of consonants. However, whereas [h] is entirely unknown in indigenous Australian languages, most of the other languages without true fricatives do have [h] in their consonant inventory.

Voicing contrasts in fricatives are largely confined to Europe, Africa, and Western Asia. Languages of South and East Asia, such as Mandarin Chinese, Korean, and the Austronesian languages, typically do not have such voiced fricatives as [z] and [v], which are familiar to many European speakers. In some Dravidian languages they occur as allophones. These voiced fricatives are also relatively rare in indigenous languages of the Americas. Overall, voicing contrasts in fricatives are much rarer than in plosives, being found only in about a third of the world's languages as compared to 60 percent for plosive voicing contrasts.^[10]

About 15 percent of the world's languages, however, have unpaired voiced fricatives, i.e. a voiced fricative without a voiceless counterpart. Two-thirds of these, or 10 percent of all languages, have unpaired voiced fricatives but no voicing contrast between any fricative pair.^[11]

This phenomenon occurs because voiced fricatives have developed from lenition of plosives or fortition of approximants. This phenomenon of unpaired voiced fricatives is scattered throughout the world, but is confined to nonsibilant fricatives with the exception of a couple of languages that have [ʒ] but lack [ʃ]. (Relatedly, several languages have the voiced affricate [dʒ] but lack [tʃ], and vice versa.) The fricatives that occur most often without a voiceless counterpart are – in order of ratio of unpaired occurrences to total occurrences – [ʝ], [β], [ð], [ʁ] and [ɣ].

Acoustics

Fricatives appear in waveforms as somewhat random noise caused by the turbulent airflow, upon which a periodic pattern is overlaid if voiced.^[12] Fricatives produced in the front of the mouth tend to have energy concentration at higher frequencies than ones produced in the back.^[13] The centre of gravity (CoG), i.e. the average frequency in a spectrum weighted by the amplitude (also known as spectral mean), may be used to determine the place of articulation of a fricative relative to that of another.^[14]

Notes

^ There are likely to be more aspirated, murmured and nasal fricatives than shown here. ⟨s̄ ṣ ŝ⟩ are not IPA transcription.
