 Phoneme |
Template:Otheruse Template:Unreferenced Template:Expert-verify In human language, a phoneme (from the Template:Lang-el, phōnēma, "a sound uttered") is the smallest posited structural unit that distinguishes meaning, though they carry no semantic content themselves. In theoretical terms, phonemes are not the physical segments themselves, but cognitive abstractions or categorizations of them. In effect, a phoneme is a group of slightly different sounds which are all perceived to have the same function by speakers of the language in question. An example of a phoneme is the Template:IPA sound in the words kit and krill. (In transcription, phonemes are placed between slashes, as here.) Even though most native speakers don't notice, in most dialects, the ks in each of these words are actually pronounced differently: they are different speech sounds, or phones (which, in transcription, are placed in square brackets). In our example, the Template:IPA in kit is aspirated, Template:IPA, while the Template:IPA in krill is not, Template:IPA. The reason why these different sounds are nonetheless considered to belong to the same phoneme in English is that if an English-speaker used one instead of the other, the meaning of the word would not change: saying Template:IPA in krill might sound odd, but the word would still be recognised. By contrast, some other sounds could be substituted which would cause a change in meaning, producing words like frill (substituting Template:IPA), grill (substituting Template:IPA) and shrill (substituting Template:IPA). These other sounds (Template:IPA, Template:IPA and Template:IPA) are, in English, different phonemes. In some languages, however, Template:IPA and Template:IPA are different phonemes, and are perceived as such by the speakers of those languages. Thus, in Icelandic, Template:IPA is the first sound of kátur 'cheerful', while Template:IPA is the first sound of gátur 'riddles'. In many languages, each letter in the spelling system represents one phoneme. However, in English spelling there is a very poor match between spelling and phonemes. For example, the two letters sh represent the single phoneme Template:IPA, while the letters k and c can both represent the phoneme Template:IPA (as in kit and cat). Phones that belong to the same phoneme, such as Template:IPA and Template:IPA for English Template:IPA, are called allophones. A common test to determine whether two phones are allophones or separate phonemes relies on finding minimal pairs: words that differ by only the phones in question. For example, the words tip and dip illustrate that Template:IPA and Template:IPA are separate phonemes, Template:IPA and Template:IPA, in English, whereas the lack of such a contrast in Korean (Template:IPA is pronounced Template:IPA, for example) indicates that in this language they are allophones of a phoneme Template:IPA. In sign languages, the basic elements of gesture and location were formerly called cheremes (or cheiremes), but general usage changed to phoneme. Tonic phonemes are sometimes called tonemes, and timing phonemes chronemes. Some linguists (such as Roman Jakobson, Morris Halle, and Noam Chomsky) consider phonemes to be further decomposable into features, such features being the true minimal constituents of language. Features overlap each other in time, as do suprasegmental phonemes in oral language and many phonemes in sign languages. Features could be designated as acoustic (Jakobson) or articulatory (Halle & Chomsky) in nature. Background and related ideasThe term phonème was reportedly first used by Dufriche-Desgenettes in 1873, but it referred to only a sound of speech. The term phoneme as an abstraction was developed by the Polish linguist Jan Niecisław Baudouin de Courtenay and his student Mikołaj Kruszewski during 1875-1895. The term used by these two was fonema, the basic unit of what they called psychophonetics. Conceptions of the phoneme were then elaborated in the works of Nikolai Trubetzkoi and others of the Prague School (during the years 1926-1935), as well as in that of structuralists like Ferdinand de Saussure, Edward Sapir, and Leonard Bloomfield. Some structuralists wished to eliminate a cognitive or psycholinguistic function for the phoneme. Later, it was also used in generative linguistics, most famously by Noam Chomsky and Morris Halle, and remains central to many accounts of the development of modern of phonology. As a theoretical concept or model, though, it has been supplemented and even replaced by others. Some languages make use of pitch for phonemic distinction. In this case, the tones used are called tonemes. Some languages distinguish words made up of the same phonemes (and tonemes) by using different durations of some elements, which are called chronemes. However, not all scholars working on languages with distinctive duration use this term. Usually, long vowels and consonants are represented either by a length indicator or doubling of the symbol in question. In sign languages, phonemes may be classified as Tab (elements of location, from Latin tabula), Dez (the hand shape, from designator), Sig (the motion, from signation), and with some researchers, Ori (orientation). Facial expressions and mouthing are also phonemic. The distinction between phonetic and phonemic systems gave rise of Kenneth Pike's concepts of Emic and etic description. NotationA transcription that only indicates the different phonemes of a language is said to be phonemic. Such transcriptions are enclosed within virgules (slashes), / /; these show that each enclosed symbol is claimed to be phonemically meaningful. On the other hand, a transcription that indicates finer detail, including allophonic variation like the two English L's, is said to be phonetic, and is enclosed in square brackets, [ ]. The common notation used in linguistics employs virgules (slashes) (/ /) around the symbol that stands for the phoneme. For example, the phoneme for the initial consonant sound in the word "phoneme" would be written as Template:IPA. In other words, the graphemes are <ph>, but this digraph represents one sound Template:IPA. Allophones, more phonetically specific descriptions of how a given phoneme might be commonly instantiated, are often denoted in linguistics by the use of diacritical or other marks added to the phoneme symbols and then placed in square brackets ([ ]) to differentiate them from the phoneme in slant brackets (/ /). The conventions of orthography are then kept separate from both phonemes and allophones by the use of angle brackets < > to enclose the spelling. The symbols of the International Phonetic Alphabet (IPA) and extended sets adapted to a particular language are often used by linguists to write phonemes of oral languages, with the principle being one symbol equals one categorical sound. Due to problems displaying some symbols in the early days of the Internet, systems such as X-SAMPA and Kirshenbaum were developed to represent IPA symbols in plain text. As of 2004, any modern web browser can display IPA symbols (as long as the operating system provides the appropriate fonts), and we use this system in this article. There are 2 published set of phonemic symbols for sign language: SignWriting and Stokoe notation. SignWriting is capable of writing any sign language and is currently used in over 38 countries. People in these countries use SignWriting on a daily basis as a natural writing system for education and recreation. Stokoe notation is used for linguistic research and was originally developed for American Sign Language. Stokoe notation has since been applied to British Sign Language by Kyle and Woll, and to Australian Aboriginal sign languages by Adam Kendon. ExamplesExamples of phonemes in the English language would include sounds from the set of English consonants, like Template:IPA and Template:IPA. These two are most often written consistently with one letter for each sound. However, phonemes might not be so apparent in written English, such as when they are typically represented with combined letters, called digraphs, like <sh> (pronounced Template:IPA) or <ch> (pronounced Template:IPA). To see a list of the phonemes in the English language, see IPA for English. Two sounds that may be allophones (sound variants belonging to the same phoneme) in one language may belong to separate phonemes in another language or dialect. In English, for example, Template:IPA has aspirated and non-aspirated allophones:aspirated as in Template:IPA, and non-aspirated as in Template:IPA. However, in many languages (e. g. Chinese), aspirated Template:IPA is a phoneme distinct from unaspirated Template:IPA. As another example, there is no distinction between Template:IPA and Template:IPA in Japanese; there is only one Template:IPA phoneme, though it has various allophones that can sound more like Template:IPA, Template:IPA, or Template:IPA to English speakers. The sounds Template:IPA and Template:IPA are distinct phonemes in English, but allophones in Spanish. The sounds Template:IPA (as in run) and Template:IPA (as in rung) are phonemes in English, but allophones in Italian and Spanish. An important phoneme is the chroneme, a phonemically-relevant extension of the duration a consonant or vowel. Some languages or dialects such as Finnish or Japanese allow chronemes after both consonants and vowels. Others, like Italian or Australian English use it after only one (in the case of Italian, consonants; in the case of Australian, vowels). Restricted phonemesA restricted phoneme is a phoneme that can only occur in a certain environment: There are restrictions as to where it can occur. English has several restricted phonemes:
BiuniquenessBiuniqueness is a criterial definition of the phoneme in classic structuralist phonemics. The biuniqueness definition states that every phonetic allophone must unambiguously be assigned to one and only one phoneme. In other words, there is a many-to-one allophone-to-phoneme mapping instead of a many-to-many mapping. The notion of biuniqueness was controversial among some pre-generative linguists and was prominently challenged by Morris Halle and Noam Chomsky in the late 1950s and early 1960s. The unworkable aspects of the concept soon become apparent if you consider sound changes/alternations and assimilation/co-articulation. Take English for its examples. If many vowels reduce to a 'schwa', what is 'schwa' then? Its own phoneme? Or totally unrelated allophones, only grouped under the phonemic vowels? Or both?

In the environments where they don't contrast, the contrast is said to be neutralized. In English there are three nasal phonemes, Template:IPA, as shown by the minimal triplet,
However, with rare exceptions, these sounds are not contrastive before plosives such as Template:IPA within the same morpheme. Although all three phones appear before plosives, for example in limp, lint, link, only one of these may appear before each of the plosives. That is, the Template:IPA distinction is neutralized before each of the plosives Template:IPA:
Thus these phonemes are not contrastive in these environments, and according to some theorists, there is no evidence as to what the underlying representation might be. If we hypothesize that we are dealing with only a single underlying nasal, there is no reason to pick one of the three phonemes Template:IPA over the other two. (In some languages there is only one phonemic nasal anywhere, and due to obligatory assimilation, it surfaces as Template:IPA in just these environments, so this idea is not as far-fetched as it might seem at first glance.) In certain schools of phonology, such a neutralized distinction is known as an archiphoneme (Nikolai Trubetzkoy of the Prague school is often associated with this analysis). Archiphonemes are often notated with a capital letter. Following this convention, the neutralization of Template:IPA before Template:IPA could be notated as |N|, and limp, lint, link would be represented as |Template:IPA|. (The |pipes| indicate underlying representation.) Other ways this archiphoneme could be notated are |m-n-ŋ|, Template:IPA}, or |n*|. Another example from American English is the neutralization of the plosives Template:IPA following a stressed syllable. Phonetically, both are realized in this position as Template:IPA, a voiced alveolar flap. This can be heard by comparing writer with rider (for the sake of simplicity, Canadian raising is not taken into account).
with the suffix -er:
Thus, one cannot say whether the underlying representation of the intervocalic consonant in either word is Template:IPA or Template:IPA without looking at the unsuffixed form. This neutralization can be represented as an archiphoneme |D|, in which case the underlying representation of writer or rider would be |Template:IPA|. Another way to talk about archiphonemes involves the concept of underspecification: phonemes can be considered fully specified segments while archiphonemes are underspecified segments. In Tuvan, phonemic vowels are specified with the articulatory features of tongue height, backness, and lip rounding. The archiphoneme |U| is an underspecified high vowel where only the tongue height is specified.
Whether |U| is pronounced as front or back and whether rounded or unrounded depends on vowel harmony. If |U| occurs following a front unrounded vowel, it will be pronounced as the phoneme Template:IPA; if following a back unrounded vowel, it will be as an Template:IPA; and if following a back rounded vowel, it will be an Template:IPA. This can been seen in the following words:
Not all phonologists accept the concept of archiphonemes. Many doubt that it reflects how people process language or control speech, and some argue that archiphonemes add unnecessary complexity. Phonological extremesOf all the sounds that a human vocal tract can create, different languages vary considerably in the number of these sounds that are considered to be distinctive phonemes in the speech of that language. Ubyx and Arrernte have only two phonemic vowels, while at the other extreme, the Bantu language Ngwe has fourteen vowel qualities, twelve of which may occur long or short, for twenty-six oral vowels, plus six nasalized vowels, long and short, for thirty-eight vowels; while !Xóõ achieves thirty-one pure vowels—not counting vowel length, which it also has—by varying the phonation. Rotokas has only six consonants, while !Xóõ has somewhere in the neighborhood of seventy-seven, and Ubyx eighty-one. French has no phonemic tone or stress, while several of the Kam-Sui languages have nine tones, and one of the Kru languages, Wobe, has been claimed to have fourteen, though this is disputed. The total phonemic inventory in languages varies from as few as eleven in Rotokas to as many as 112 in !Xóõ (including four tones). These may range from familiar sounds like Template:IPA, Template:IPA, or Template:IPA to very unusual ones produced in extraordinary ways (see: Click consonant, phonation, airstream mechanism). The English language itself uses a rather large set of thirteen to twenty-two vowels, including diphthongs, though its twenty-two to twenty-six consonants are close to average. (There are twenty-one consonant and five vowel letters in the English alphabet, but this does not correspond to the number of consonant and vowel sounds.) The most common vowel system consists of the five vowels Template:IPA. The most common consonants are Template:IPA. Very few languages lack one of these: Arabic lacks Template:IPA, standard Hawaiian lacks Template:IPA, Mohawk and Tlingit lack Template:IPA and Template:IPA, Hupa lacks both Template:IPA and a simple Template:IPA, colloquial Samoan lacks Template:IPA and Template:IPA, while Rotokas and Quileute lack Template:IPA and Template:IPA.
