However, a phoneme is generally regarded as an abstraction of a set (or equivalence class) of speech sounds (''

), but they are distributional variants of a single phoneme . Speech sounds that differ but do not create a meaningful change in the word are known as '' allophones'' of the same phoneme. Allophonic variation may be conditioned, in which case a certain phoneme is realized as a certain allophone in particular phonological environments, or it may otherwise be free, and may vary by speaker or by dialect. Therefore, phonemes are often considered to constitute an abstract underlying representation for segments of words, while speech sounds make up the corresponding phonetic realization, or the surface form.

characters.) However, descriptions of particular languages may use different conventional symbols to represent the phonemes of those languages. For languages whose writing systems employ the phonemic principle, ordinary letters may be used to denote phonemes, although this approach is often hampered by the complexity of the relationship between orthography and pronunciation (see below).


Assignment of speech sounds to phonemes

A phoneme is a sound or a group of different sounds perceived to have the same function by speakers of the language or dialect in question. An example is the
English English usually refers to: * English language * English people English may also refer to: Peoples, culture, and language * ''English'', an adjective for something of, from, or related to England ** English national ...
phoneme , which occurs in words such as ''cat'', ''kit'', ''scat'', ''skit''. Although most native speakers do not notice this, in most English dialects, the "c/k" sounds in these words are not identical: in , the sound is aspirated, but in , it is unaspirated. The words, therefore, contain different ''speech sounds'', or ''
phones A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into ele ...
'', transcribed for the aspirated form and for the unaspirated one. These different sounds are nonetheless considered to belong to the same phoneme, because if a speaker used one instead of the other, the meaning of the word would not change: using the aspirated form in ''skill'' might sound odd, but the word would still be recognized. By contrast, some other sounds would cause a change in meaning if substituted: for example, substitution of the sound would produce the different word ''still'', and that sound must therefore be considered to represent a different phoneme (the phoneme ). The above shows that in English, and are allophones of a single phoneme . In some languages, however, and are perceived by native speakers as different sounds, and substituting one for the other can change the meaning of a word. In those languages, therefore, the two sounds represent different phonemes. For example, in Icelandic, is the first sound of , meaning "cheerful", but is the first sound of , meaning "riddles". Icelandic, therefore, has two separate phonemes and .


Minimal pairs

A pair of words like and (above) that differ only in one phone is called a
minimal pair In phonology, minimal pairs are pairs of words or phrases in a particular language, spoken or signed, that differ in only one phonological element, such as a phoneme, toneme or chroneme, and have distinct meanings. They are used to demonstrate ...
for the two alternative phones in question (in this case, and ). The existence of minimal pairs is a common test to decide whether two phones represent different phonemes or are allophones of the same phoneme. To take another example, the minimal pair ''tip'' and ''dip'' illustrates that in English, and belong to separate phonemes, and ; since both words have different meanings, English-speakers must be conscious of the distinction between the two sounds. Signed languages, such as American Sign Language (ASL), also have minimal pairs, differing only in (exactly) one of the signs' parameters: handshape, movement, location, palm orientation, and

or marker. A minimal pair may exist in the signed language if the basic sign stays the same, but one of the parameters changes. However, the absence of minimal pairs for a given pair of phones does not always mean that they belong to the same phoneme: they may be so dissimilar phonetically that it is unlikely for speakers to perceive them as the same sound. For example, English has no minimal pair for the sounds (as in ''hat'') and (as in ''bang''), and the fact that they can be shown to be in complementary distribution could be used to argue for their being allophones of the same phoneme. However, they are so dissimilar phonetically that they are considered separate phonemes. Phonologists have sometimes had recourse to "near minimal pairs" to show that speakers of the language perceive two sounds as significantly different even if no exact minimal pair exists in the lexicon. It is virtually impossible to find a minimal pair to distinguish English from , yet it seems uncontroversial to claim that the two consonants are distinct phonemes. The two words 'pressure' and 'pleasure' can serve as a near minimal pair.


Suprasegmental phonemes

Besides segmental phonemes such as vowels and consonants, there are also suprasegmental features of pronunciation (such as tone and stress, syllable boundaries and other forms of juncture, nasalization and
vowel harmony In phonology, vowel harmony is an assimilatory process in which the vowels of a given domain – typically a phonological word – have to be members of the same natural class (thus "in harmony"). Vowel harmony is typically long distance, me ...
), which, in many languages, change the meaning of words and so are phonemic. ''Phonemic stress'' is encountered in languages such as English. For example, there are two words spelled ''invite'', one is a verb and is stressed on the second syllable, the other is a noun and stressed on the first syllable (without changing any of the individual sounds). The position of the stress distinguishes the words and so a full phonemic specification would include indication of the position of the stress: for the verb, for the noun. In other languages, such as
French French (french: français(e), link=no) may refer to: * Something of, from, or related to France ** French language, which originated in France, and its various dialects and accents ** French people, a nation and ethnic group identified with Franc ...
, word stress cannot have this function (its position is generally predictable) and so it is not phonemic (and therefore not usually indicated in dictionaries). ''Phonemic tones'' are found in languages such as
Mandarin Chinese Mandarin (; ) is a group of Chinese (Sinitic) dialects that are natively spoken across most of northern and southwestern China. The group includes the Beijing dialect, the basis of the phonology of Standard Chinese, the official language ...
in which a given syllable can have five different tonal pronunciations: The tone "phonemes" in such languages are sometimes called ''tonemes''. Languages such as English do not have phonemic tone, but they use intonation for functions such as emphasis and attitude.


Distribution of allophones

When a phoneme has more than one allophone, the one actually heard at a given occurrence of that phoneme may be dependent on the phonetic environment (surrounding sounds). Allophones that normally cannot appear in the same environment are said to be in complementary distribution. In other cases, the choice of allophone may be dependent on the individual speaker or other unpredictable factors. Such allophones are said to be in free variation, but allophones are still selected in a specific phonetic context, not the other way around.


Background and related ideas

The term ''phonème'' (from grc, φώνημα, phōnēma, "sound made, utterance, thing spoken, speech, language"Liddell, H.G. & Scott, R. (1940). ''A Greek-English Lexicon. revised and augmented throughout by Sir Henry Stuart Jones. with the assistance of. Roderick McKenzie.'' Oxford: Clarendon Press.) was reportedly first used by
A. Dufriche-Desgenettes Antoni Dufriche-Desgenettes (26 February 1804, Paris – 19 December 1878, Saint-Mandé), baptized ''Antoine Marie Dufriche-Foulaines'', was a French seafaring merchant, poet and amateur phonetician. Biography His father François Nicolas, a broth ...
in 1873, but it referred only to a speech sound. The term ''phoneme'' as an abstraction was developed by the Polish linguist Jan 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''. Daniel Jones became the first linguist in the western world to use the term ''phoneme'' in its current sense, employing the word in his article "The phonetic structure of the Sechuana Language". The concept of the phoneme was then elaborated in the works of Nikolai Trubetzkoy and others of the Prague School (during the years 1926–1935), and in those of structuralists like Ferdinand de Saussure, Edward Sapir, and Leonard Bloomfield. Some structuralists (though not Sapir) rejected the idea of a cognitive or psycholinguistic function for the phoneme. Later, it was used and redefined in generative linguistics, most famously by Noam Chomsky and Morris Halle, and remains central to many accounts of the development of modern
phonology Phonology is the branch of linguistics that studies how languages or dialects systematically organize their sounds or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a ...
. As a theoretical concept or model, though, it has been supplemented and even replaced by others. Some linguists (such as Roman Jakobson and Morris Halle) proposed that phonemes may 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 characterized in different ways: Jakobson and colleagues defined them in acoustic terms, Chomsky and Halle used a predominantly articulatory basis, though retaining some acoustic features, while Ladefoged's system is a purely articulatory system apart from the use of the acoustic term 'sibilant'. In the description of some languages, the term

Restrictions on occurrence

Languages do not generally allow words or syllables to be built of any arbitrary sequences of phonemes. There are phonotactic restrictions on which sequences of phonemes are possible and in which environments certain phonemes can occur. Phonemes that are significantly limited by such restrictions may be called ''restricted phonemes''. In English, examples of such restrictions include the following: * , as in ''sing'', occurs only at the end of a syllable, never at the beginning (in many other languages, such as

Some phonotactic restrictions can alternatively be analyzed as cases of neutralization. See Neutralization and archiphonemes below, particularly the example of the occurrence of the three English nasals before stops.


Biuniqueness

Biuniqueness is a requirement of classic structuralist phonemics. It means that a given phone, wherever it occurs, must unambiguously be assigned to one and only one phoneme. In other words, the mapping between phones and phonemes is required to be many-to-one rather than many-to-many. The notion of biuniqueness was controversial among some pre-

. This may cause either or (in the appropriate environments) to be realized with the phone (an alveolar flap). For example, the same flap sound may be heard in the words ''hitting'' and ''bidding'', although it is intended to realize the phoneme in the first word and in the second. This appears to contradict biuniqueness. For further discussion of such cases, see the next section.


Neutralization and archiphonemes

Phonemes that are contrastive in certain environments may not be contrastive in all environments. In the environments where they do not contrast, the contrast is said to be neutralized. In these positions it may become less clear which phoneme a given phone represents. Absolute neutralization is a phenomenon in which a segment of the underlying representation is not realized in any of its phonetic representations (surface forms). The term was introduced by

(1968), and contrasts with contextual neutralization where some phonemes are not contrastive in certain environments. Some phonologists prefer not to specify a unique phoneme in such cases, since to do so would mean providing redundant or even arbitrary information – instead they use the technique of

. An archiphoneme is an object sometimes used to represent an underspecified phoneme. An example of neutralization is provided by the Russian vowels and . These phonemes are contrasting in stressed syllables, but in unstressed syllables the contrast is lost, since both are reduced to the same sound, usually (for details, see

). In order to assign such an instance of to one of the phonemes and , it is necessary to consider morphological factors (such as which of the vowels occurs in other forms of the words, or which inflectional pattern is followed). In some cases even this may not provide an unambiguous answer. A description using the approach of underspecification would not attempt to assign to a specific phoneme in some or all of these cases, although it might be assigned to an archiphoneme, written something like , which reflects the two neutralized phonemes in this position, or , reflecting its unmerged values. A somewhat different example is found in English, with the three

boundary between them), only one of the nasals is possible in any given position: before , before or , and before , as in ''limp, lint, link'' (, , ). The nasals are therefore not contrastive in these environments, and according to some theorists this makes it inappropriate to assign the nasal phones heard here to any one of the phonemes (even though, in this case, the phonetic evidence is unambiguous). Instead they may analyze these phones as belonging to a single archiphoneme, written something like , and state the underlying representations of ''limp, lint, link'' to be . This latter type of analysis is often associated with Nikolai Trubetzkoy of the Prague school. Archiphonemes are often notated with a capital letter within double virgules or pipes, as with the examples and given above. Other ways the second of these has been notated include , and . Another example from English, but this time involving complete phonetic convergence as in the Russian example, is the flapping of and in some American English (described above under Biuniqueness). Here the words ''betting'' and ''bedding'' might both be pronounced . Under the generative grammar theory of linguistics, if a speaker applies such flapping consistently, morphological evidence (the pronunciation of the related forms ''bet'' and ''bed'', for example) would reveal which phoneme the flap represents, once it is known which morpheme is being used. However, other theorists would prefer not to make such a determination, and simply assign the flap in both cases to a single archiphoneme, written (for example) . Further mergers in English are plosives after , where conflate with , as suggested by the alternative spellings '' sketti'' and ''sghetti''. That is, there is no particular reason to transcribe ''spin'' as rather than as , other than its historical development, and it might be less ambiguously transcribed .


Morphophonemes

s are built up. A morphophoneme within a morpheme can be expressed in different ways in different allomorphs of that morpheme (according to morphophonological rules). For example, the English plural morpheme ''-s'' appearing in words such as ''cats'' and ''dogs'' can be considered to be a single morphophoneme, which might be transcribed (for example) or , and which is realized phonemically as after most voiceless consonants (as in ''cats'') and as in other cases (as in ''dogs'').


Numbers of phonemes in different languages

All known languages use only a small subset of the many possible sounds that the human speech organs can produce, and, because of allophony, the number of distinct phonemes will generally be smaller than the number of identifiably different sounds. Different languages vary considerably in the number of phonemes they have in their systems (although apparent variation may sometimes result from the different approaches taken by the linguists doing the analysis). The total phonemic inventory in languages varies from as few as 9–11 in Pirahã and 11 in Rotokas to as many as 141 in !Xũ. The number of phonemically distinct vowels can be as low as two, as in Ubykh and

The non-uniqueness of phonemic solutions

During the development of phoneme theory in the mid-20th century phonologists were concerned not only with the procedures and principles involved in producing a phonemic analysis of the sounds of a given language, but also with the reality or uniqueness of the phonemic solution. These were central concerns of

. Some writers took the position expressed by Kenneth Pike: "There is only one accurate phonemic analysis for a given set of data", while others believed that different analyses, equally valid, could be made for the same data.
Yuen Ren Chao Yuen Ren Chao (; 3 November 1892 – 25 February 1982), also known as Zhao Yuanren, was a Chinese-American linguist, educator, scholar, poet, and composer, who contributed to the modern study of Chinese phonology and grammar. Chao was born a ...
(1934), in his article "The non-uniqueness of phonemic solutions of phonetic systems" stated "given the sounds of a language, there are usually more than one possible way of reducing them to a set of phonemes, and these different systems or solutions are not simply correct or incorrect, but may be regarded only as being good or bad for various purposes". The linguist F. W. Householder referred to this argument within linguistics as "God's Truth" (i.e. the stance that a given language has an intrinsic structure to be discovered) vs. "hocus-pocus" (i.e. the stance that any proposed, coherent structure is as good as any other). Different analyses of the English vowel system may be used to illustrate this. The article English phonology states that "English has a particularly large number of vowel phonemes" and that "there are 20 vowel phonemes in Received Pronunciation, 14–16 in General American and 20–21 in Australian English". Although these figures are often quoted as fact, they actually reflect just one of many possible analyses, and later in the English Phonology article an alternative analysis is suggested in which some diphthongs and long vowels may be interpreted as comprising a short vowel linked to either or . The fullest exposition of this approach is found in Trager and Smith (1951), where all long vowels and diphthongs ("complex nuclei") are made up of a short vowel combined with either , or (plus for rhotic accents), each comprising two phonemes. The transcription for the vowel normally transcribed would instead be , would be and would be , or /ar/ in a rhotic accent if there is an in the spelling. It is also possible to treat English long vowels and diphthongs as combinations of two vowel phonemes, with long vowels treated as a sequence of two short vowels, so that 'palm' would be represented as /paam/. English can thus be said to have around seven vowel phonemes, or even six if schwa were treated as an allophone of or of other short vowels. In the same period there was disagreement about the correct basis for a phonemic analysis. The structuralist position was that the analysis should be made purely on the basis of the sound elements and their distribution, with no reference to extraneous factors such as grammar, morphology or the intuitions of the native speaker; this position is strongly associated with Leonard Bloomfield. Zellig Harris claimed that it is possible to discover the phonemes of a language purely by examining the distribution of phonetic segments. Referring to mentalistic definitions of the phoneme, Twaddell (1935) stated "Such a definition is invalid because (1) we have no right to guess about the linguistic workings of an inaccessible 'mind', and (2) we can secure no advantage from such guesses. The linguistic processes of the 'mind' as such are quite simply unobservable; and introspection about linguistic processes is notoriously a fire in a wooden stove." This approach was opposed to that of Edward Sapir, who gave an important role to native speakers' intuitions about where a particular sound or group of sounds fitted into a pattern. Using English as an example, Sapir argued that, despite the superficial appearance that this sound belongs to a group of three nasal consonant phonemes (/m/, /n/ and /ŋ/), native speakers feel that the velar nasal is really the sequence �ɡ. The theory of generative phonology which emerged in the 1960s explicitly rejected the Structuralist approach to phonology and favoured the mentalistic or cognitive view of Sapir. These topics are discussed further in English phonology#Controversial issues.

s), the correspondence between spelling and pronunciation in a given language may be highly distorted; this is the case with English, for example. The correspondence between symbols and phonemes in alphabetic writing systems is not necessarily a one-to-one correspondence.

(both representing phonemes ). Also a single letter may represent two phonemes, as in English representing or . There may also exist spelling/pronunciation rules (such as those for the pronunciation of in Italian) that further complicate the correspondence of letters to phonemes, although they need not affect the ability to predict the pronunciation from the spelling and vice versa, provided the rules are known.


In sign languages

Sign language phonemes are bundles of articulation features. Stokoe was the first scholar to describe the phonemic system of ASL. He identified the bundles '' tab'' (elements of location, from Latin ''tabula''), '' dez'' (the handshape, from ''designator''), '' sig'' (the motion, from ''signation''). Some researchers also discern '' ori'' (orientation), facial expression or mouthing. Just as with spoken languages, when features are combined, they create phonemes. As in spoken languages, sign languages have minimal pairs which differ in only one phoneme. For instance, the ASL signs for
father
' and
mother
' differ minimally with respect to location while handshape and movement are identical; location is thus contrastive. Stokoe's terminology and notation system are no longer used by researchers to describe the phonemes of sign languages; William Stokoe's research, while still considered seminal, has been found not to characterize American Sign Language or other sign languages sufficiently. For instance, non-manual features are not included in Stokoe's classification. More sophisticated models of sign language phonology have since been proposed by Brentari, Sandler, and Van der Kooij.


Chereme

and phoneme previously used in the study of sign languages. A ''chereme'', as the basic unit of signed communication, is functionally and psychologically equivalent to the phonemes of oral languages, and has been replaced by that term in the academic literature. ''Cherology'', as the study of ''cheremes'' in language, is thus equivalent to phonology. The terms are not in use anymore. Instead, the terms ''phonology'' and ''phoneme'' (or ''distinctive feature'') are used to stress the linguistic similarities between signed and spoken languages. The terms were coined in 1960 by William Stokoe at Gallaudet University to describe sign languages as true and full languages. Once a controversial idea, the position is now universally accepted in linguistics. Stokoe's terminology, however, has been largely abandoned.Seegmiller, 2006.
