Voiceless alveolar fricative

A voiceless alveolar sibilant is a common consonant sound in spoken languages. It is the sound in English words such as sea and pass, and is represented in the International Phonetic Alphabet with . 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 or . Voiceless alveolar sibilants are one of the most common sounds cross-linguistically. If a language has fricatives, it will most likely have . However, some languages have a related sibilant sound, such as , but no . In addition, sibilants are absent from most Australian Aboriginal languages, in which fricatives are rare; however, does occur in Kalaw Lagaw Ya. 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 Iberia (e.g., Astur-Leonese, Catalan, Basque, Galician, Portuguese and Spanish) have a so-called "voiceless apico-alveolar sibilant" that lacks the strong hissing of the described in this article but has a duller, more "grave" sound quality somewhat reminiscent of a voiceless retroflex sibilant. Basque, Mirandese 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 (for the northern Iberian sound) vs. (for the more common sound), but Ladefoged and Maddieson claim that English can be pronounced apically, which is evidently not the same as the apical sibilant of Iberian Spanish and Basque. Also, Adams 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 tongue shape. Adams describes the northern Iberian sibilant as "retracted". Ladefoged and Maddieson appear to characterize the more common hissing variant as grooved, but there is some doubt about whether all and only the "hissing" sounds actually have a "grooved" tongue shape. Features Features of a voiceless alveolar sibilant: • There are at least three specific variants of : • 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 is very strong. • 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 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 or (to a lesser extent) . Occurrence Dentalized laminal alveolar Alveolar Retracted alveolar == Voiceless apico-alveolar sibilant ==

The voiceless alveolar retracted sibilant (commonly termed the voiceless apico-alveolar sibilant) is a fricative that is articulated with the tongue in a hollow shape, usually with the tip of the tongue (apex) against the alveolar ridge. It is a sibilant sound and is found most notably in a number of languages in a linguistic area covering northern and central Iberia. It is most well known from its occurrence in the Spanish of this area. In the Middle Ages, it occurred in a wider area, covering Romance languages spoken throughout France, Portugal, and Spain, as well as Old High German and Middle High German. Occurrence in Europe Modern In Romance languages, it occurs as the normal voiceless alveolar sibilant in Astur-Leonese, Castilian Spanish, Catalan, Galician, northern European Portuguese, and some Occitan dialects. It also occurs in Basque and Mirandese, where it is opposed to a different voiceless alveolar sibilant, the more common ; the same distinction occurs in a few dialects of northeastern Portuguese. Outside this area, it also occurs in a few dialects of Latin American Spanish (e.g. Antioqueño and Pastuso, in Colombia). Amongst Germanic languages, it occurs in Dutch (and closely related Low German), Icelandic, many dialects in Scandinavia, and working-class Glaswegian English. There is no single IPA symbol used for this sound. The symbol is often used, with a diacritic indicating an pronunciation. However, that is potentially problematic in that not all alveolar retracted sibilants are apical (see below), and not all apical alveolar sibilants are retracted. The ad hoc non-IPA symbols and are often used in the linguistic literature even when IPA symbols are used for other sounds, but is a common transcription of the retroflex sibilant . Medieval In medieval times, it occurred in a wider area, including the Romance languages spoken in most or all of France and Iberia (Old Spanish, Galician-Portuguese, Catalan, French, etc.), as well as in the Old and Middle High German of central and southern Germany, and most likely Northern Germany as well. In all of these languages, the retracted "apico-alveolar" sibilant was opposed to a non-retracted sibilant much like modern English , and in many of them, both voiceless and voiced versions of both sounds occurred. A solid type of evidence consists of different spellings used for two different sibilants: in general, the retracted "apico-alveolar" variants were written or , while the non-retracted variants were written , or . In the Romance languages, the retracted sibilants derived from Latin , or , while the non-retracted sibilants derived from earlier affricates and , which in turn derived from palatalized or . The situation was similar in High German, where the retracted sibilants derived largely from Proto-Germanic , while the non-retracted sibilants derived from instances of Proto-Germanic that were shifted by the High German sound shift. Minimal pairs were common in all languages. Examples in Middle High German, for example, were "to know" (Old English , cf. "to wit") vs. "known" (Old English ), and "white" (Old English ) vs. "way" (Old English , 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 palato-alveolar . For this reason, when borrowed into such languages or represented with non-Latin characters, it is often replaced with . This occurred, for example, in English borrowings from Old French (e.g. push from pousser, cash from caisse); in Polish borrowings from medieval German (e.g. from kosten, from sūr (contemporary )); and in representations of Mozarabic (an extinct medieval Romance language once spoken in southern Spain) in Arabic characters. The similarity between retracted and has resulted in many exchanges in Spanish between the sounds, during the medieval period when Spanish had both phonemes. Examples are (formerly xabón) "soap" from Latin /, "cuttlefish" (formerly xibia) from Latin , and "scissors" (earlier Especially in Alemannic, every pre-consonantal became . Loss-causing events Those languages in which the sound occurs typically did not have a phonological process from which either or 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, was reached from -ti-, -ci-, -ce- (, , ) clusters that eventually became , , and later , , (as in Latin fortia "force", civitas "city", centum "hundred"), while was reached: • From a or 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 in Northern France and southern-central Portugal, as in French chat "cat", Portuguese achar "find". In High German, was reached through a > > process, as in German Wasser compared to English water. In English, the same process of Romance > occurred in Norman-imported words, accounting for modern homophones sell and cell. 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 , lacked both processes. The Germanic-speaking regions that did not have either phenomenon have normally preserved the apical , 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 and , and preserved the apical S at the expense of both, that were shifted farther away. Galician, Catalan and Ladino changed only . Reach in ancient times Because of the widespread medieval distribution, it has been speculated that retracted was the normal pronunciation in spoken Latin. Certain borrowings suggest that it was not far off from the postalveolar sibilant , e.g. Biblical Hebrew () or Jewish Palestinian Aramaic () > Koine Greek () > Late Latin (), Biblical Hebrew () > Koine Greek () > Late Latin ; but this could also be explained by the lack of a better sound in Greek (and consequently Latin) to represent Semitic š. It equally well could have been an areal feature inherited from the prehistoric languages of Western Europe, as evidenced by its occurrence in modern Basque. For the same reasons, it can be speculated that retracted 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 Greece, suggests it could have ultimately been the main allophone of Proto-Indo-European *s, known for ranging from to as far as . , but not , was developed in Italian. However, where Spanish and Catalan have apical , Italian uses the same laminal 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 or depending on context, much as in European Portuguese, which could attest to the previous existence of in the Italian Peninsula. The Italian pronunciation as laminal S could also be explained by the presence of but not , thus moving the pronunciation of to the front of the mouth in an attempt to better differentiate between the two sounds. A voiceless laminal dental or dentialveolar sibilant contrasts with a voiceless apical alveolar or post-alveolar sibilant in Basque and several languages of California, including Luiseño of the Uto-Aztecan family and Kumeyaay of the Yuman family. ==Voiceless alveolar non-sibilant fricative==

A voiceless alveolar non-sibilant fricative (also known as a slit fricative) is a consonantal sound in some spoken languages. As the International Phonetic Alphabet does not have separate symbols for non-sibilant alveolar fricatives, this sound can be transcribed by use of diacritics, such as (a retracted ) or (a lowered , appears in the IPA Handbook). Additional symbols include (with the alveolar diacritic, in extIPA) and (a raised and devoiced , typically part of the affricate ). Features However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant. Occurrence Voiceless alveolar tapped fricative A few languages also have a voiceless alveolar tapped fricative, which is simply a very brief 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, such as . 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. Voiceless alveolar approximant A voiceless alveolar approximant is a similar sound with less turbulence in the airflow. The IPA symbol is . Some authors have used the transcription for this sound. ==See also==
