Fricatives are consonants produced by forcing air through a narrow channel made by placing two articulators close together [1] . These may be the lower lip against the upper teeth, in the case of [f]; the back of the tongue against the soft palate, in the case of German [x] (the final consonant of Bach ); or the side of the tongue against the molars, in the case of Welsh [ɬ] (appearing twice in the name Llanelli ). This turbulent airflow is called frication.

Consonant sound in spoken language, articulated with complete or partial closure of the vocal tract

In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are, pronounced with the lips;, pronounced with the front of the tongue;, pronounced with the back of the tongue;, pronounced in the throat; and, pronounced by forcing air through a narrow channel (fricatives); and and, which have air flowing through the nose (nasals). Contrasting with consonants are vowels.

Manner of articulation configuration and interaction of the articulators when making a speech sound

In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another. Others include those involved in the r-like sounds, and the sibilancy of fricatives.

Place of articulation Place in the mouth consonants are articulated

In articulatory phonetics, the place of articulation of a consonant is the point of contact where an obstruction occurs in the vocal tract between an articulatory gesture, an active articulator, and a passive location. Along with the manner of articulation and the phonation, it gives the consonant its distinctive sound.

Contents

A particular subset of fricatives are the sibilants . When forming a sibilant, one still is forcing air through a narrow channel, but in addition, the tongue is curled lengthwise to direct the air over the edge of the teeth [1] . English [s], [z], [ʃ], and [ʒ] are examples of sibilants.

Sibilants are fricatives of higher amplitude and pitch, made by directing a stream of air with the tongue towards the teeth. Examples of sibilants are the consonants at the beginning of the English words sip, zip, ship, and genre. The symbols in the International Phonetic Alphabet used to denote the sibilant sounds in these words are, respectively,. Sibilants have a characteristically intense sound, which accounts for their paralinguistic use in getting one's attention.

The usage of two other terms is less standardized: "Spirant" is an older term for fricatives used by some American and European phoneticians and phonologists [2] . "Strident" could mean just "sibilant", but some authors[ who? ] include also labiodental and uvular fricatives in the class.

In phonetics, labiodentals are consonants articulated with the lower lip and the upper teeth.

Uvulars are consonants articulated with the back of the tongue against or near the uvula, that is, further back in the mouth than velar consonants. Uvulars may be stops, fricatives, nasals, trills, or approximants, though the IPA does not provide a separate symbol for the approximant, and the symbol for the voiced fricative is used instead. Uvular affricates can certainly be made but are rare: they occur in some southern High-German dialects, as well as in a few African and Native American languages. Uvular consonants are typically incompatible with advanced tongue root, and they often cause retraction of neighboring vowels.

Types

Sibilants

A voiceless alveolar fricative is a type of fricative consonant pronounced with the tip or blade of the tongue against the alveolar ridge just behind the teeth. This refers to a class of sounds, not a single sound. There are at least six types with significant perceptual differences:

The voiced alveolar fricatives are consonantal sounds. The symbol in the International Phonetic Alphabet that represents these sounds depends on whether a sibilant or non-sibilant fricative is being described.

Voiceless fricatives produced in the postalveolar region include the voiceless palato-alveolar fricative, the voiceless postalveolar non-sibilant fricative, the voiceless retroflex fricative, and the voiceless alveolo-palatal fricative. This article discusses the first two.

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.

Coronal consonants are consonants articulated with the flexible front part of the tongue. Among places of articulation, only the coronal consonants can be divided into as many articulation types: apical, laminal, domed, or subapical as well as different postalveolar articulations : palato-alveolar, alveolo-palatal and retroflex. Only the front of the tongue (coronal) has such dexterity among the major places of articulation, allowing such variety of distinctions. Coronals have another dimension, grooved, to make sibilants in combination with the orientations above.

A dental consonant is a consonant articulated with the tongue against the upper teeth, such as, ,, and in some languages. Dentals are usually distinguished from sounds in which contact is made with the tongue and the gum ridge, as in English because of the acoustic similarity of the sounds and the fact that in the Roman alphabet, they are generally written using the same symbols.

Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli of the superior teeth. Alveolar consonants may be articulated with the tip of the tongue, as in English, or with the flat of the tongue just above the tip, as in French and Spanish. The laminal alveolar articulation is often mistakenly called dental, because the tip of the tongue can be seen near to or touching the teeth. However, it is the rearmost point of contact that defines the place of articulation; this is where the oral cavity ends, and it is the resonant space of the oral cavity that gives consonants and vowels their characteristics. The International Phonetic Alphabet (IPA) does not have separate symbols for the alveolar consonants. Rather, the same symbol is used for all coronal places of articulation that are not palatalized like English palato-alveolar sh, or retroflex. To disambiguate, the bridge may be used for a dental consonant, or the under-bar may be used for the postalveolars. Note that differs from dental in that the former is a sibilant and the latter is not. differs from postalveolar in being unpalatalized. The bare letters, etc. cannot be assumed to specifically represent alveolars. The language may not make such distinctions, such that two or more coronal places of articulation are found allophonically, or the transcription may simply be too broad to distinguish dental from alveolar. If it is necessary to specify a consonant as alveolar, a diacritic from the Extended IPA may be used:, etc., though that could also mean extra-retracted. The letters ⟨s, t, n, l⟩ are frequently called 'alveolar', and the language examples below are all alveolar sounds.

Central non-sibilant fricatives

Voiceless bilabial fricative Consonantal sound

The voiceless bilabial fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɸ⟩.

Voiced bilabial fricative consonantal sound

The voiced bilabial fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨β⟩, and the equivalent X-SAMPA symbol is B. The symbol ⟨β⟩ is the Greek letter beta.

The voiceless labiodental fricative is a type of consonantal sound, used in a number of spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨f⟩.

The IPA also has letters for epiglottal fricatives,

with allophonic trilling, but these might be better analyzed as pharyngeal trills. [3]

Lateral fricatives

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.

IPA letters used for both fricatives and approximants

No language distinguishes voiced 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, [ʁ̝, ʕ̝]. Likewise, the downtack may be added to specify an approximant realization, [ʁ̞, 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

In many languages, such as English, the glottal "fricatives" are unaccompanied phonation states of the glottis, without any accompanying manner, fricative or otherwise. However, in languages such as Arabic, they are true fricatives. [1] [ page needed ]

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. [sʰ] contrasts with [s] in Korean; aspirated fricatives are also found in a few Sino-Tibetan languages, in some Oto-Manguean languages, and in the Siouan language Ofo (/sʰ/ and /fʰ/). The record may be Cone Tibetan, which has four contrastive aspirated fricatives: /sʰ//ɕʰ/, /ʂʰ/, and /xʰ/. [4]

Nasalized fricatives

Phonemically nasalized fricatives are rare. Some South Arabian languages have /z̃/, 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. [5]

Occurrence

H is not a fricative in English (see /h/). [ dubious ]

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. [6] 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, the Dravidian and Austronesian languages, typically do not have such voiced fricatives as [z] and [v], which are familiar to many European speakers. 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. [7]

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. [8]

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 random noise caused by the turbulent airflow, upon which a periodic pattern is overlaid if voiced. [9] Fricatives produced in the front of the mouth tend to have energy concentration at higher frequencies than ones produced in the back. [10] The centre of gravity, the average frequency in a spectrum weighted by the amplitude, may be used to determine the place of articulation of a fricative relative to that of another. [11]

Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class of sounds includes lateral approximants like, non-lateral approximants like, and semivowels like and.

A lateral is consonant in which the airstream proceeds along the sides of the tongue, but it is blocked by the tongue from going through the middle of the mouth. An example of a lateral consonant is the English l, as in Larry.

An affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation. It is often difficult to decide if a stop and fricative form a single phoneme or a consonant pair. English has two affricate phonemes, and, often spelled ch and j, respectively.

Pharyngealization secondary articulation of consonants or vowels where the pharynx or epiglottis is constricted during articulation

Pharyngealization is a secondary articulation of consonants or vowels by which the pharynx or epiglottis is constricted during the articulation of the sound.

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.

Digraph (orthography) pair of characters used to write one phoneme

A digraph or digram is a pair of characters used in the orthography of a language to write either a single phoneme, or a sequence of phonemes that does not correspond to the normal values of the two characters combined.

Postalveolar consonants are consonants articulated with the tongue near or touching the back of the alveolar ridge, farther back in the mouth than the alveolar consonants, which are at the ridge itself but not as far back as the hard palate, the place of articulation for palatal consonants. Examples of postalveolar consonants are the English palato-alveolar consonants, as in the words "ship", "'chill", "vision", and "jump", respectively.

In phonetics, palato-alveolar consonants are postalveolar consonants, nearly always sibilants, that are weakly palatalized with a domed (bunched-up) tongue. They are common sounds cross-linguistically and occur in English words such as ship and chip.

Retroflex consonant Type of consonant articulation

A retroflex consonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants, especially in Indology. Other terms occasionally encountered are apico-domal and cacuminal.

The phonology of Catalan, a Romance language, has a certain degree of dialectal variation. Although there are two standard dialects, one based on Eastern Catalan and one based on Valencian, this article deals with features of all or most dialects, as well as regional pronunciation differences. Various studies have focused on different Catalan varieties; for example, Wheeler (1979) and Mascaró (1976) analyze Central Eastern varieties, the former focusing on the educated speech of Barcelona and the latter focusing more on the vernacular of Barcelona, and Recasens (1986) does a careful phonetic study of Central Eastern Catalan.

An apical consonant is a phone produced by obstructing the air passage with the tip of the tongue. It contrasts with laminal consonants, which are produced by creating an obstruction with the blade of the tongue, just behind the tip.

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.

Unlike many languages, Icelandic has only very minor dialectal differences in sounds. The language has both monophthongs and diphthongs, and many consonants can be voiced or unvoiced.

In linguistics, palatalization is a sound change that either results in a palatal or palatalized consonant or a front vowel, or is triggered by one of them. Palatalization involves change in the place or manner of articulation of consonants, or the fronting or raising of vowels. In some cases, palatalization involves assimilation or lenition.

The voiceless retroflex lateral approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɭ̊⟩, and the equivalent X-SAMPA symbol is l`_0.
