102-436: ARPABET (also spelled ARPAbet ) is a set of phonetic transcription codes developed by Advanced Research Projects Agency (ARPA) as a part of their Speech Understanding Research project in the 1970s. It represents phonemes and allophones of General American English with distinct sequences of ASCII characters. Two systems, one representing each segment with one character (alternating upper- and lower-case letters) and

204-435: A phonetic transcription should be enclosed in square brackets "[ ]". A transcription that specifically denotes only phonemic contrasts may be enclosed in slashes "/ /" instead. If one is unsure, it is best to use brackets since by setting off a transcription with slashes, one makes a theoretical claim that every symbol phonemically contrasts for the language being transcribed. For phonetic transcriptions, there

306-636: A 'one sound one symbol' policy, or may even be restricted to the ASCII symbols of a typical keyboard, as in the SAMPA alphabet. For example, the English word church may be transcribed as /tʃɝːtʃ/ , a close approximation of its actual pronunciation, or more abstractly as /crc/ , which is easier to type. Phonemic symbols should always be backed up by an explanation of their use and meaning, especially when they are as divergent from actual pronunciation as /crc/ . Occasionally

408-537: A broad transcription. Most phonetic transcription is based on the assumption that linguistic sounds are segmentable into discrete units that can be represented by symbols. Many different types of transcription, or "notation", have been tried out: these may be divided into Alphabetic (which are based on the same principle as that which governs ordinary alphabetic writing, namely that of using one single simple symbol to represent each sound) and Analphabetic (notations which are not alphabetic) which represent each sound by

510-416: A broader or narrower way. A transcription which includes some allophonic detail but is still closely linked to the phonemic structure of an utterance is called an allophonic transcription . The advantage of narrower transcription is that it can help learners to produce exactly the right sound and allows linguists to make detailed analyses of language variation. The disadvantage is that a narrow transcription

612-414: A composite symbol made up of a number of signs put together. The International Phonetic Alphabet (IPA) is the most widely used and well-known of present-day phonetic alphabets and has a long history . It was created in the nineteenth century by European language teachers and linguists. It soon developed beyond its original purpose as a tool of foreign language pedagogy and is now also used extensively as

714-499: A determination, and simply assign the flap in both cases to a single archiphoneme, written (for example) //D// . Further mergers in English are plosives after /s/ , where /p, t, k/ conflate with /b, d, ɡ/ , as suggested by the alternative spellings sketti and sghetti . That is, there is no particular reason to transcribe spin as /ˈspɪn/ rather than as /ˈsbɪn/ , other than its historical development, and it might be less ambiguously transcribed //ˈsBɪn// . A morphophoneme

816-462: 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 . A phoneme might be represented by a combination of two or more letters ( digraph , trigraph , etc. ), like ⟨sh⟩ in English or ⟨sch⟩ in German (both representing

918-512: A given language should be analyzed in phonemic terms. Generally, a phoneme is regarded as an abstraction of a set (or equivalence class ) of spoken sound variations that are nevertheless perceived as a single basic unit of sound by the ordinary native speakers of a given language. While phonemes are considered an abstract underlying representation for sound segments within words, the corresponding phonetic realizations of those phonemes—each phoneme with its various allophones—constitute

1020-425: A native English speaker would recognize that underneath this, they represent the same plural ending. This can be indicated with the pipe notation. If the plural ending is thought to be essentially an s , as English spelling would suggest, the words can be transcribed |pɛts| and |bɛds| . If it is essentially a z , these would be |pɛtz| and |bɛdz| . A double slash (" ⫽ ⫽ ")

1122-406: A near minimal pair. The reason why this is still acceptable proof of phonemehood is that there is nothing about the additional difference (/r/ vs. /l/) that can be expected to somehow condition a voicing difference for a single underlying postalveolar fricative. One can, however, find true minimal pairs for /ʃ/ and /ʒ/ if less common words are considered. For example, ' Confucian ' and 'confusion' are

1224-436: A one-to-one relationship between sound and symbol than is possible with the language's orthography. Phonetic transcription allows one to step outside orthography, examine differences in pronunciation between dialects within a given language and identify changes in pronunciation that may take place over time. A basic principle of phonetic transcription is that it should be applicable to all languages, and its symbols should denote

1326-483: 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

1428-504: A practical alphabet of phoneticians and linguists. It is found in many dictionaries, where it is used to indicate the pronunciation of words, but most American dictionaries for native English-speakers, e.g., American Heritage Dictionary of the English Language , Random House Dictionary of the English Language , Webster's Third New International Dictionary , avoid phonetic transcription and instead employ respelling systems based on

1530-417: 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

1632-456: A simple /k/ , colloquial Samoan lacks /t/ and /n/ , while Rotokas and Quileute lack /m/ and /n/ . 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 phonology . Some writers took

1734-435: A single morphophoneme, which might be transcribed (for example) //z// or |z| , and which is realized phonemically as /s/ after most voiceless consonants (as in cat s ) and as /z/ in other cases (as in dog s ). 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

1836-657: A single phoneme in some other languages, such as Spanish, in which [pan] and [paŋ] for instance are merely interpreted by Spanish speakers as regional or dialect-specific ways of pronouncing the same word ( pan : the Spanish word for "bread"). Such spoken variations of a single phoneme are known by linguists as allophones . Linguists use slashes in the IPA to transcribe phonemes but square brackets to transcribe more precise pronunciation details, including allophones; they describe this basic distinction as phonemic versus phonetic . Thus,

1938-466: A single phoneme: the one traditionally represented in the IPA as /t/ . For computer-typing purposes, systems such as X-SAMPA exist to represent IPA symbols using only ASCII 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

2040-542: A specific phonetic context, not the other way around. The term phonème (from Ancient Greek : φώνημα , romanized :  phōnēma , "sound made, utterance, thing spoken, speech, language" ) was reportedly first used by A. Dufriche-Desgenettes 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

2142-419: A transcription will be enclosed in pipes ("| |"). This goes beyond phonology into morphological analysis. For example, the words pets and beds could be transcribed phonetically as [pʰɛʔts] and [b̥ɛd̥z̥] (in a fairly narrow transcription), and phonemically as /pɛts/ and /bɛdz/ . Because /s/ and /z/ are separate phonemes in English, they receive separate symbols in the phonemic analysis. However,

2244-467: A unique phoneme in such cases, since to do so would mean providing redundant or even arbitrary information – instead they use the technique of underspecification . An archiphoneme is an object sometimes used to represent an underspecified phoneme. An example of neutralization is provided by the Russian vowels /a/ and /o/ . These phonemes are contrasting in stressed syllables, but in unstressed syllables

2346-452: A valid minimal pair. 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 ), 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

2448-602: A vowel resembling [ o ] ( L-vocalization ). Thus, on the one hand, phonetically, little can be represented as something like [ˈɫɪɾɫ̩] in many American, Canadian, and Australian accents but [ˈlɪʔo] in a southern England accent. Furthermore, in Australian accents especially, the first-syllable vowel of little tends to be higher than in North America, leading to the possibility of employing an even narrower phonetic transcription to indicate this, such as [ˈɫɪ̝ɾɫ̩] . On

2550-421: A writing system that can be used to represent phonemes. Since /l/ and /t/ alone distinguish certain words from others, they are each examples of phonemes of the English language. Specifically they are consonant phonemes, along with /s/ , while /ɛ/ is a vowel phoneme. The spelling of English does not strictly conform to its phonemes, so that the words knot , nut , and gnat , regardless of spelling, all share

2652-418: Is a purely articulatory system apart from the use of the acoustic term 'sibilant'. In the description of some languages, the term chroneme has been used to indicate contrastive length or duration of phonemes. In languages in which tones are phonemic, the tone phonemes may be called tonemes . Though not all scholars working on such languages use these terms, they are by no means obsolete. By analogy with

2754-414: Is a theoretical unit at a deeper level of abstraction than traditional phonemes, and is taken to be a unit from which morphemes 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

2856-439: 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: /ɪnˈvaɪt/ for the verb, /ˈɪnvaɪt/ for the noun. In other languages, such as French , word stress cannot have this function (its position

2958-641: 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

3060-444: Is being used, so that, for example, the English word jet is not read as "yet". This is done with angle brackets or chevrons : ⟨jet⟩ . It is also common to italicize such words, but the chevrons indicate specifically that they are in the original language's orthography, and not in English transliteration . In iconic phonetic notation, the shapes of the phonetic characters are designed so that they visually represent

3162-411: Is called a minimal pair for the two alternative phones in question (in this case, [kʰ] and [k] ). 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 t ip and d ip illustrates that in English, [t] and [d] belong to separate phonemes, /t/ and /d/ ; since

3264-422: Is flexibility in how closely sounds may be transcribed. A transcription that gives only a basic idea of the sounds of a language in the broadest terms is called a broad transcription ; in some cases, it may be equivalent to a phonemic transcription (only without any theoretical claims). A close transcription, indicating precise details of the sounds, is called a narrow transcription . They are not binary choices but

3366-500: 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 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. When

3468-427: Is more precise than alphabetic notation is analphabetic phonetic notation. Instead of both the alphabetic and iconic notational types' general principle of using one symbol per sound, analphabetic notation uses long sequences of symbols to precisely describe the component features of an articulatory gesture (MacMahon 1996:842–844). This type of notation is reminiscent of the notation used in chemical formulas to denote

3570-430: 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 [ŋ] 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

3672-408: Is often imperfect, as pronunciations naturally shift in a language over time, rendering previous spelling systems outdated or no longer closely representative of the sounds of the language (see § Correspondence between letters and phonemes below). 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

3774-472: Is part of a larger goal of scientific description of phonetics, is particularly interesting in its challenge against the descriptive method of the phoneticians who created alphabetic systems like the IPA. An example of Pike's system can be demonstrated by the following. A syllabic voiced alveolar nasal consonant ( [n̩] in IPA) is notated as In Pike's notation there are 5 main components (which are indicated using

3876-492: 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

3978-404: Is rarely representative of all dialects or speakers of a language. Most American, Canadian, and Australian speakers of English would pronounce the /t/ in the word little as a tap [ ɾ ] and the initial /l/ as a dark L (often represented as [ɫ] ), but speakers in southern England pronounce the /t/ as [ ʔ ] (a glottal stop ; see t-glottalization ) and the second /l/ as

4080-406: Is sometimes used to mark a diaphonemic transcription. Diaphonemic transcriptions accommodate for the variation between the phonemic systems of different varieties or diasystems of a language. For example, if a speaker of variety A pronounces the lexical set BATH with an [ɑː] as in the lexical set PALM , whereas a speaker of variety B pronounces the lexical set BATH with an [æ] as in

4182-461: Is that it involves a large number of symbols and diacritics that may be unfamiliar to nonspecialists. Broad transcription usually allows statements to be made which apply across accents and dialects, and is thus more appropriate for the pronunciation data in ordinary dictionaries, which may discuss phonetic details in the preface but rarely give them for each entry. Most linguists use a narrow transcription only when necessary, and at all other times use

4284-412: Is that the sound spelled with the symbol t is usually articulated with a glottal stop [ʔ] (or a similar glottalized sound) in the word cat , an alveolar flap [ɾ] in dating , an alveolar plosive [t] in stick , and an aspirated alveolar plosive [tʰ] in tie ; however, American speakers perceive or "hear" all of these sounds (usually with no conscious effort) as merely being allophones of

4386-497: Is the English phoneme /k/ , which occurs in words such as c at , k it , s c at , s k it . Although most native speakers do not notice this, in most English dialects, the "c/k" sounds in these words are not identical: in kit [kʰɪt] , the sound is aspirated, but in skill [skɪl] , it is unaspirated. The words, therefore, contain different speech sounds , or phones , transcribed [kʰ] for

4488-609: Is the symbol chosen for the English consonant at the beginning of the words 'rue', 'rye', 'red': this is frequently transcribed as /r/, despite the symbol suggesting an association with the IPA symbol [r] which is used for a tongue-tip trill . It is equally possible within a phonemic transcription to use the symbol /ɹ/ , which in IPA usage refers to an alveolar approximant ; this is the more common realization for English pronunciation in America and England. Phonemic symbols will frequently be chosen to avoid diacritics as much as possible, under

4590-575: Is used in the TIMIT corpus. Stress is indicated by a digit immediately following a vowel. Auxiliary symbols are identical in 1- and 2-letter codes. In 2-letter notation, segments are separated by a space. In TIMIT , the following symbols are used in addition to the ones listed above: Phonetic transcription The pronunciation of words in all languages changes over time. However, their written forms ( orthography ) are often not modified to take account of such changes, and do not accurately represent

4692-765: The Kam–Sui languages have six to nine tones (depending on how they are counted), and the Kam-Sui Dong language has nine to 15 tones by the same measure. One of the Kru languages , Wobé , has been claimed to have 14, though this is disputed. The most common vowel system consists of the five vowels /i/, /e/, /a/, /o/, /u/ . The most common consonants are /p/, /t/, /k/, /m/, /n/ . Relatively few languages lack any of these consonants, although it does happen: for example, Arabic lacks /p/ , standard Hawaiian lacks /t/ , Mohawk and Tlingit lack /p/ and /m/ , Hupa lacks both /p/ and

4794-520: The Prague school . Archiphonemes are often notated with a capital letter within double virgules or pipes, as with the examples //A// and //N// given above. Other ways the second of these has been notated include |m-n-ŋ| , {m, n, ŋ} and //n*// . Another example from English, but this time involving complete phonetic convergence as in the Russian example, is the flapping of /t/ and /d/ in some American English (described above under Biuniqueness ).

4896-764: The Uralic Phonetic Alphabet ) and Caucasian languages . This is often labeled the Americanist phonetic alphabet despite having been widely used for languages outside the Americas. The principal difference between these alphabets and the IPA is that the specially created characters of the IPA are abandoned in favour of already existing typewriter characters with diacritics (e.g. many characters are borrowed from Eastern European orthographies) or digraphs . Examples of this transcription may be seen in Pike's Phonemics and in many of

4998-867: 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. Cherology and chereme (from Ancient Greek : χείρ "hand") are synonyms of phonology and phoneme previously used in

5100-592: 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 / j / or / w / . 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 /j/ , /w/ or /h/ (plus /r/ for rhotic accents), each comprising two phonemes. The transcription for

5304-462: The approach of underspecification would not attempt to assign [ə] to a specific phoneme in some or all of these cases, although it might be assigned to an archiphoneme, written something like //A// , which reflects the two neutralized phonemes in this position, or {a|o} , reflecting its unmerged values. A somewhat different example is found in English, with the three nasal phonemes /m, n, ŋ/ . In word-final position these all contrast, as shown by

5406-477: The appropriate environments) to be realized with the phone [ɾ] (an alveolar flap ). For example, the same flap sound may be heard in the words hi tt ing and bi dd ing , although it is intended to realize the phoneme /t/ in the first word and /d/ in the second. This appears to contradict biuniqueness. For further discussion of such cases, see the next section. Phonemes that are contrastive in certain environments may not be contrastive in all environments. In

5508-436: The aspirated form and [k] 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 [kʰ] 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

5610-526: The composition of chemical compounds. Although more descriptive than alphabetic notation, analphabetic notation is less practical for many purposes (e.g. for descriptive linguists doing fieldwork or for speech pathologists transcribing their impressions of speech disorders). As a result, this type of notation is uncommon. Two examples of this type were developed by the Danish Otto Jespersen (1889) and American Kenneth Pike (1943). Pike's system, which

5712-537: The consonant phonemes /n/ and /t/ , differing only by their internal vowel phonemes: /ɒ/ , /ʌ/ , and /æ/ , respectively. Similarly, /pʊʃt/ is the notation for a sequence of four phonemes, /p/ , /ʊ/ , /ʃ/ , and /t/ , that together constitute the word pushed . Sounds that are perceived as phonemes vary by languages and dialects, so that [ n ] and [ ŋ ] are separate phonemes in English since they distinguish words like sin from sing ( /sɪn/ versus /sɪŋ/ ), yet they comprise

5814-459: The contrast is lost, since both are reduced to the same sound, usually [ə] (for details, see vowel reduction in Russian ). In order to assign such an instance of [ə] to one of the phonemes /a/ and /o/ , 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

5916-428: The devisers of the alphabet chose not to represent the phonemic effect of vowel length. However, because changes in the spoken language are often not accompanied by changes in the established orthography (as well as other reasons, including dialect differences, the effects of morphophonology on orthography, and the use of foreign spellings for some loanwords ), the correspondence between spelling and pronunciation in

6018-419: The differences between individual speakers or even whole dialects of the same language). Phonemic transcription provides a representation only of a language's abstract word-distinguishing units of sound ( phonemes ), and thus is not really a phonetic transcription at all (though at times it may coincide with one). Instead, a phonetic transcription focuses on more exact articulatory or acoustic details, whether in

6120-622: The ends of a continuum, with many possibilities in between. All are enclosed in brackets. For example, in some dialects the English word pretzel in a narrow transcription would be [ˈpɹ̥ʷɛʔts.ɫ̩] , which notes several phonetic features that may not be evident even to a native speaker. An example of a broad transcription is [ˈpɹ̥ɛts.ɫ̩] , which indicates only some of the features that are easier to hear. A yet broader transcription would be [ˈpɹɛts.l] in which every symbol represents an unambiguous speech sound but without going into any unnecessary detail. None of those transcriptions makes any claims about

6222-544: 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 Paul Kiparsky (1968), and contrasts with contextual neutralization where some phonemes are not contrastive in certain environments. Some phonologists prefer not to specify

See Neutralization and archiphonemes below, particularly the example of the occurrence of the three English nasals before stops. Biuniqueness is a requirement of classic structuralist phonemics.

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 .

Some linguists (such as Roman Jakobson and Morris Halle ) proposed that phonemes may be further decomposable into features , such features being

It is challenging to find a minimal pair to distinguish English / ʃ / from / ʒ / , yet it seems uncontroversial to claim that the two consonants are distinct phonemes.

To avoid confusion with IPA symbols, it may be desirable to specify when native orthography

6834-532: 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- generative linguists and was prominently challenged by Morris Halle and Noam Chomsky in the late 1950s and early 1960s. An example of the problems arising from the biuniqueness requirement is provided by the phenomenon of flapping in North American English . This may cause either /t/ or /d/ (in

6936-457: The meaning of a word. In those languages, therefore, the two sounds represent different phonemes. For example, in Icelandic , [kʰ] is the first sound of kátur , meaning "cheerful", but [k] is the first sound of gátur , meaning "riddles". Icelandic, therefore, has two separate phonemes /kʰ/ and /k/ . A pair of words like kátur and gátur (above) that differ only in one phone

However, before a stop such as /p, t, k/ (provided there is no morpheme boundary between them), only one of the nasals is possible in any given position: /m/ before /p/ , /n/ before /t/ or /d/ , and /ŋ/ before /k/ , as in limp, lint, link ( /lɪmp/ , /lɪnt/ , /lɪŋk/ ). The nasals are therefore not contrastive in these environments, and according to some theorists this makes it inappropriate to assign

7140-456: The most noticeable phonetic features of an utterance, whereas narrow transcription encodes more information about the phonetic details of the allophones in the utterance. The difference between broad and narrow is a continuum, but the difference between phonemic and phonetic transcription is usually treated as a binary distinction. Phonemic transcription is a particularly broad transcription that disregards all allophonic differences (for example

Instead they may analyze these phonemes as belonging to a single archiphoneme, written something like //N// , and state the underlying representations of limp, lint, link to be //lɪNp//, //lɪNt//, //lɪNk// . This latter type of analysis is often associated with Nikolai Trubetzkoy of

7344-636: 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 ǃXũ . The number of phonemically distinct vowels can be as low as two, as in Ubykh and Arrernte . At

7446-556: The other extreme, the Bantu language Ngwe has 14 vowel qualities, 12 of which may occur long or short, making 26 oral vowels, plus six nasalized vowels, long and short, making a total of 38 vowels; while !Xóõ achieves 31 pure vowels, not counting its additional variation by vowel length, by varying the phonation . As regards consonant phonemes, Puinave and the Papuan language Tauade each have just seven, and Rotokas has only six. !Xóõ , on

7548-590: The other hand, a broad phonemic transcription of little is also possible that ignores all the above specifics of these aforementioned dialects; this can be useful in situations where minor details are not important to distinguish or where the emphasis is on overarching patterns. For example, one typical phonemic transcription for the word little is /ˈlɪtᵊl/ , as is common in both British and American English dictionaries. (Slashes, rather than square brackets, are used to indicate phonemic rather than phonetic representations.) A further disadvantage of narrow transcription

7650-461: The other hand, has somewhere around 77, and Ubykh 81. The English language uses a rather large set of 13 to 21 vowel phonemes, including diphthongs, although its 22 to 26 consonants are close to average. Across all languages, the average number of consonant phonemes per language is about 22, while the average number of vowel phonemes is about 8. Some languages, such as French , have no phonemic tone or stress , while Cantonese and several of

7752-764: The other with one or two (case-insensitive), were devised, the latter being far more widely adopted. ARPABET has been used in several speech synthesizers , including Computalker for the S-100 system, SAM for the Commodore 64 , SAY for the Amiga , TextAssist for the PC and Speakeasy from Intelligent Artefacts which used the Votrax SC-01 speech synthesiser IC. It is also used in the CMU Pronouncing Dictionary . A revised version of ARPABET

7854-539: The papers reprinted in Joos's Readings in Linguistics 1 . In the days before it was possible to create phonetic fonts for computer printers and computerized typesetting, this system allowed material to be typed on existing typewriters to create printable material. There are also extended versions of the IPA, for example: Ext-IPA , VoQS , and Luciano Canepari 's IPA . The International Phonetic Association recommends that

7956-449: The phoneme /ʃ/ ). Also a single letter may represent two phonemes, as in English ⟨x⟩ representing /gz/ or /ks/ . There may also exist spelling/pronunciation rules (such as those for the pronunciation of ⟨c⟩ in Italian ) that further complicate the correspondence of letters to phonemes, although they need not affect the ability to predict the pronunciation from

8058-785: The phoneme, linguists have proposed other sorts of underlying objects, giving them names with the suffix -eme , such as morpheme and grapheme . These are sometimes called emic units . The latter term was first used by Kenneth Pike , who also generalized the concepts of emic and etic description (from phonemic and phonetic respectively) to applications outside linguistics. 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

8160-422: The phonemic status of the sounds. Instead, they represent certain ways in which it is possible to produce the sounds that make up the word. There are also several possibilities in how to transcribe the word phonemically, but here, the differences are generally of not precision but analysis. For example, pretzel could be /ˈprɛts.l̩/ or /ˈprɛts.əl/ . The latter transcription suggests that there are two vowels in

8262-418: 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 (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

8364-548: The position of articulators in the vocal tract. This is unlike alphabetic notation, where the correspondence between character shape and articulator position is arbitrary. This notation is potentially more flexible than alphabetic notation in showing more shades of pronunciation (MacMahon 1996:838–841). An example of iconic phonetic notation is the Visible Speech system, created by Scottish phonetician Alexander Melville Bell (Ellis 1869:15). Another type of phonetic notation that

8466-498: The pronunciation patterns of tap versus tab , or pat versus bat , can be represented phonemically and are written between slashes (including /p/ , /b/ , etc.), while nuances of exactly how a speaker pronounces /p/ are phonetic and written between brackets, like [p] for the p in spit versus [pʰ] for the p in pit , which in English is an aspirated allophone of /p/ (i.e., pronounced with an extra burst of air). There are many views as to exactly what phonemes are and how

8568-437: The pronunciation. Words borrowed from other languages may retain the spelling from the original language, which may have a different system of correspondences between written symbols and speech sounds. Pronunciation can also vary greatly among dialects of a language. Standard orthography in some languages, such as English and Tibetan , is often irregular and makes it difficult to predict pronunciation from spelling. For example,

8670-425: 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

8772-501: The same phoneme. However, they are so dissimilar phonetically that they are considered separate phonemes. A case like this shows that sometimes it is the systemic distinctions and not the lexical context which are decisive in establishing phonemes. This implies that the phoneme should be defined as the smallest phonological unit which is contrastive at a lexical level or distinctive at a systemic level. Phonologists have sometimes had recourse to "near minimal pairs" to show that speakers of

8874-437: The same phonetic properties whatever the language being transcribed. It follows that a transcription devised for one individual language or group of languages is not a phonetic transcription but an orthography. Phonetic transcription may be used to transcribe the phones of a language. In all systems of transcription there is a distinction between broad transcription and narrow transcription . Broad transcription indicates only

8976-513: 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 [h] (as in h at ) and [ŋ] (as in ba ng ), and the fact that they can be shown to be in complementary distribution could be used to argue for their being allophones of

9078-412: The sound [t] would produce the different word s t ill , and that sound must therefore be considered to represent a different phoneme (the phoneme /t/ ). The above shows that in English, [k] and [kʰ] are allophones of a single phoneme /k/ . In some languages, however, [kʰ] and [k] are perceived by native speakers as significantly different sounds, and substituting one for the other can change

9180-499: The spatial-gestural equivalent in sign languages ), and all spoken languages include both consonant and vowel phonemes. Phonemes are primarily studied under the branch of linguistics known as phonology . The English words cell and set have the exact same sequence of sounds, except for being different in their final consonant sounds: thus, /sɛl/ versus /sɛt/ in the International Phonetic Alphabet (IPA),

9282-641: The spelling and vice versa, provided the rules are consistent. 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 ), and 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,

9384-442: 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

9486-499: The surface form that is actually uttered and heard. Allophones each have technically different articulations inside particular words or particular environments within words , yet these differences do not create any meaningful distinctions. Alternatively, at least one of those articulations could be feasibly used in all such words with these words still being recognized as such by users of the language. An example in American English

9588-405: 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

9690-403: The velar nasal is really the sequence [ŋɡ]/. 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 . Phonemes are considered to be the basis for alphabetic writing systems. In such systems

9792-554: The vowel normally transcribed /aɪ/ would instead be /aj/ , /aʊ/ would be /aw/ and /ɑː/ would be /ah/ , or /ar/ in a rhotic accent if there is an ⟨r⟩ 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 /ʌ/ or of other short vowels. In

9894-424: The word even if they cannot both be heard, but the former suggests that there is only one. Strictly speaking, it is not possible to have a distinction between "broad" and "narrow" within phonemic transcription, since the symbols chosen represent only sounds that have been shown to be distinctive. However, the symbols themselves may be more or less explicit about their phonetic realization. A frequently cited example

9996-417: The words betting and bedding might both be pronounced [ˈbɛɾɪŋ] . 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

10098-500: The words bough , tough , cough , though and through do not rhyme in English even though their spellings might suggest otherwise. Other languages, such as Spanish and Italian have a more consistent (but still imperfect) relationship between orthography and pronunciation, while a few languages may claim to have a fully phonemic spelling system (a phonemic orthography ). For most languages, phonetic transcription makes it possible to show pronunciation with something much nearer to

10200-410: The 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 nonmanual signal or marker. A minimal pair may exist in the signed language if the basic sign stays

10302-447: The written symbols ( graphemes ) represent, in principle, the phonemes of the language being written. This is most obviously the case when the alphabet was invented with a particular language in mind; for example, the Latin alphabet was devised for Classical Latin, and therefore the Latin of that period enjoyed a near one-to-one correspondence between phonemes and graphemes in most cases, though

10404-679: 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
