Voiceless alveolar fricative

The voiceless alveolar fricatives are a type of

(gum line) 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 voiceless alveolar sibilant [s] has a strong hissing sound, as the s in English sink. It is one of the most common sounds in the world.
• The voiceless denti-alveolar sibilant [s̄] (an ad hoc notation), also called apico-dental, has a weaker lisping sound like English th in thin. It occurs in Spanish dialects in southern Spain (eastern Andalusia). ^{[citation needed]}
• The voiceless alveolar retracted sibilant [s̠], and the subform apico-alveolar [s̺], or called grave, has a weak hushing sound reminiscent of retroflex fricatives. It is used in the languages of northern Iberia, like Asturleonese, Basque, Peninsular Spanish (excluding parts of Andalusia), Catalan, Galician, and Northern European Portuguese. A similar retracted sibilant form is also used in Dutch, Icelandic, some southern dialects of Swedish, Finnish, and Greek. The retracted "S" is also used in Amerindian languages such as Muscogee, Garifuna, and many varieties of Quechua. It was supposedly the standard sound of s in Latin. ^{[citation needed]} Its sound is between [s] and [ʃ].
• The voiceless alveolar non-sibilant fricative [θ̠] or [θ͇], using the alveolar diacritic from the Extended IPA,^[1] is similar to the th in English thin. It occurs in Icelandic as well as an intervocalic and word-final allophone of English /t/ in dialects such as Hiberno-English and Scouse.
• The
  voiceless alveolar lateral fricative [ɬ] sounds like a voiceless, strongly articulated version of English l (somewhat like what the English cluster **hl would sound like) and is written as ll in Welsh
  .

The first three types are sibilants, meaning that they are made by directing a stream of air with the tongue towards the teeth and have a piercing, perceptually prominent sound.

The voiceless alveolar sibilant is a common consonant sound in vocal languages. It is the sound in English words such as sea and pass, and is represented in the International Phonetic Alphabet with ⟨s⟩. It has a characteristic high-pitched, highly perceptible hissing sound. For this reason, it is often used to get someone's attention, using a call often written as sssst! or psssst!.

The voiceless alveolar sibilant [s] is one of the most common sounds cross-linguistically. If a language has fricatives, it will most likely have [s].^[2] However, some languages have a related sibilant sound, such as [ʃ], but no [s]. In addition, sibilants are absent from most Australian Aboriginal languages, in which fricatives are rare; however, [s] does occur in Kalaw Lagaw Ya.^[3]

Medieval

In medieval times, it occurred in a wider area, including the

witan, cf. "to wit") vs. wissen "known" (Old English wissen), and wīz "white" (Old English wīt) vs. wīs(e) "way" (Old English wīs, cf. "-wise").

Description of the retracted sibilant

Often, to speakers of languages or dialects that do not have the sound, it is said to have a "whistling" quality, and to sound similar to

once spoken in southern Spain) in Arabic characters. The similarity between retracted [s̺] and [ʃ] has resulted in many exchanges in Spanish between the sounds, during the medieval period when Spanish had both phonemes. Examples are jabón (formerly xabón) "soap" from Latin sapō/sapōnem, jibia "cuttlefish" (formerly xibia) from Latin sēpia, and tijeras "scissors" (earlier tixeras < medieval tiseras) from Latin cīsōrias (with initial t- due to influence from tōnsor "shaver").

One of the clearest descriptions of this sound is from Obaid:[6] "There is a Castilian s, which is a voiceless, concave, apicoalveolar fricative: The tip of the tongue turned upward forms a narrow opening against the alveoli of the upper incisors. It resembles a faint /ʃ/ and is found throughout much of the northern half of Spain".

Many dialects of

Loss of the voiceless alveolar sibilant

This distinction has since vanished from most of the languages that once had it in medieval times.

• In most dialects of Spanish, the four alveolar sibilants have merged into the non-retracted [s] (
  distinción). Distinción is also preserved in Spanish orthography
  on both sides of the Atlantic.
• In French and most dialects of Portuguese, the four alveolar sibilants have merged into non-retracted [s] and [z], while in European Portuguese, most other Old World Portuguese variants and some recently European-influenced dialects of Brazil all instances of coda [s̺], voiced [z̺] before voiced consonants, were backed to [ʃ], while in most of Brazilian Portuguese this phenomenon is much rarer, being essentially absent in the dialects that had a greater indigenous and/or non-Portuguese European influence.
• In the remaining dialects of Portuguese, found in northern Portugal, they merged into the retracted [s̺] [z̺], or, as in
  Asturian-Leonese
  ), conserved the medieval distinction.
• In German, [s̺] was early on voiced to [z̺] in prevocalic position. This sound was then fronted to [z], but did not merge with any other sound (except that it was later re-devoiced in some southern dialects). In pre-consonantal and final position, [s̺] merged with either [s] or [ʃ]. The rules for these mergers differ between dialects. In Standard German, [ʃ] is used stem-initially and sporadically after ‹r›. Especially in Alemannic, every pre-consonantal [s̺] became [ʃ].

Loss-causing events

Those languages in which the sound occurs typically did not have a phonological process from which either [s] or [ʃ] appeared, two similar sounds with which ⟨s̺⟩ was eventually confused. In general, older European languages only had a single pronunciation of s.

In Romance languages, [s] was reached from -ti-, -ci-, -ce- ([ti], [ki], [ke]) clusters that eventually became [ts], [tsi], [tse] and later [s], [si], [se] (as in Latin fortia "force", civitas "city", centum "hundred"), while [ʃ] was reached:

• From a [sk] or [ks] cluster in southern Romance, as in Latin miscere > Portuguese mexer "to move", Latin fluxus > Spanish flojo "lax", Latin crescere > Italian crescere "grow", with a different pronunciation.
• from a deaffricated [tʃ] in Northern France and southern-central Portugal, as in French chat "cat", Portuguese achar "find".

In High German, [s] was reached through a [t] > [ts] > [s] process, as in German Wasser compared to English water. In English, the same process of Romance [ts] > [s] occurred in Norman-imported words, accounting for modern homophones sell and cell. [ʃ] was also reached from a -sk- cluster reduction as in Romance, e.g. Old English spelling asc for modern ash, German schiff and English ship compared to Danish skib.

Exceptions

Standard Modern Greek, which has apical [s̺], lacked both processes.

The Germanic-speaking regions that did not have either phenomenon have normally preserved the apical [s̺], that is, Icelandic, Dutch and many Scandinavian lects. It is also found in a minority of Low German dialects.

The main Romance language to preserve the sound, Castilian Spanish, is exceptional in that it had both events that produced [s] and [ʃ], and preserved the apical S at the expense of both, that were shifted farther away. Galician, Catalan and Ladino changed only [s].

Reach in ancient times

Because of the widespread medieval distribution, it has been speculated that retracted [s̺] was the normal pronunciation in spoken

.

For the same reasons, it can be speculated that retracted [s̺] was the pronunciation of Proto-Germanic s. Its presence in many branches of Indo-European and its presence particularly in the more conservative languages inside each branch (e.g. Icelandic, Spanish), as well as being found in disparate areas, such as the Baltic languages and Greece, suggests it could have ultimately been the main allophone of Proto-Indo-European s,^[5] known for ranging from [s] to as far as [ɕ].

[ʃ], but not [s], was developed in Italian. However, where Spanish and Catalan have apical [s̺], Italian uses the same laminal [s] that occurs in standard forms of English: evidence, it could be argued, that S was not pronounced apically in Latin. But Neapolitan has a medieval S becoming either [s] or [ʃ] depending on context, much as in European Portuguese, which could attest to the previous existence of [s̺] in the Italian Peninsula. The Italian pronunciation as laminal S could also be explained by the presence of [ʃ] but not [s], thus moving the pronunciation of [s̺] to the front of the mouth in an attempt to better differentiate between the two sounds.

Comparison between English and Spanish

The term "voiceless alveolar sibilant" is potentially ambiguous in that it can refer to at least two different sounds. Various languages of northern

and some Portuguese dialects in northeast Portugal (as well as medieval Spanish and Portuguese in general) have both types of sounds in the same language.

There is no general agreement about what actual feature distinguishes these sounds. Spanish phoneticians normally describe the difference as apical (for the northern Iberian sound) vs. laminal (for the more common sound), but Ladefoged and Maddieson^[7] claim that English /s/ can be pronounced apically, which is evidently not the same as the apical sibilant of Iberian Spanish and Basque. Also, Adams^[8] asserts that many dialects of Modern Greek have a laminal sibilant with a sound quality similar to the "apico-alveolar" sibilant of northern Iberia.

Some authors have instead suggested that the difference lies in

(which is more or less a synonym of "grooved"), but in both cases, there is some doubt about whether all and only the "hissing" sounds actually have a "grooved" or "sulcal" tongue shape.

Features

Features of the voiceless alveolar sibilant:

• Its manner of articulation is sibilant fricative, which means it is generally produced by channeling air flow along a groove in the back of the tongue up to the place of articulation, at which point it is focused against the sharp edge of the nearly clenched teeth, causing high-frequency turbulence.
• There are at least three specific variants of [s]:
  • Dentalized laminal alveolar (commonly called "dental"), which means it is articulated with the tongue blade very close to the upper front teeth, with the tongue tip resting behind lower front teeth. The hissing effect in this variety of [s] is very strong.^[9]
  • Non-retracted alveolar, which means it is articulated with either the tip or the blade of the tongue at the
    alveolar ridge, termed respectively apical and laminal. According to Ladefoged & Maddieson (1996) about half of English
    speakers use a non-retracted apical articulation.
  • Retracted alveolar, which means it is articulated with either the tip or the blade of the tongue slightly behind the alveolar ridge, termed respectively apical and laminal. Acoustically, it is close to laminal [ʂ] or (to a lesser extent) [ʃ].
• Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
• It is an oral consonant, which means air is allowed to escape through the mouth only.
• It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
• The
  intercostal muscles and abdominal muscles
  , as in most sounds.

The voiceless alveolar non-sibilant fricative (also known as a "slit" fricative) is a consonantal sound. As the

retracted

or alveolarized [θ], respectively), ⟨ɹ̝̊⟩ (constricted voiceless [ɹ]), or ⟨t̞⟩ (lowered [t]).

Some scholars also posit the voiceless alveolar approximant distinct from the fricative. The approximant may be represented in the IPA as ⟨ɹ̥⟩.

Few languages also have the voiceless alveolar tapped fricative, which is simply a very brief apical alveolar non-sibilant fricative, with the tongue making the gesture for a tapped stop but not making full contact. This can be indicated in the IPA with the lowering diacritic to show full occlusion did not occur.[86]

Tapped fricatives are occasionally reported in the literature, though these claims are not generally independently confirmed and so remain dubious.

Flapped fricatives are theoretically possible but are not attested.^[86]

Features

• Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence. However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant.
• Its
  alveolar ridge, termed respectively apical and laminal
  .
• Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
• It is an oral consonant, which means air is allowed to escape through the mouth only.
• It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
• The

The voiceless alveolar non-sibilant fricative (also known as a "lisp" fricative) is a consonantal sound. Consonants is pronounced with simultaneous lateral and central airflow.

Features

• Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence. However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant.
• Its
  alveolar ridge, termed respectively apical and laminal
  .
• Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
• It is an oral consonant, which means air is allowed to escape through the mouth only.
• It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
• It is a lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
• The
  intercostal muscles and abdominal muscles
  , as in most sounds.
