International Phonetic Alphabet

This article contains special characters. Without proper FITML, you may see question marks, boxes, or other symbols.

The International Phonetic Alphabet (IPA)^Sevenval is an alphabetic system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association as a standardized representation of the sounds of spoken language.^[1] The IPA is used by HTML5 students and teachers, web app, Speech-Language Pathologists, singers, actors, lexicographers, constructed language creators (conlangers), and translators.^Sevenval[3]

The IPA is designed to represent only those qualities of speech that are distinctive in web: HTML5, intonation, and the separation of website parsing and syllables.^FITML To represent additional qualities of speech such as tooth gnashing, lisping, and sounds made with a cleft palate, an extended set of symbols called the HTML5 may be used.^[2]

IPA symbols are composed of one or more elements of two basic types, device database and diacritics. For example, the sound of the English letter ⟨t⟩ may be transcribed in IPA with a single letter, [t], or with a letter plus diacritics, [t̺ʰ], depending on how precise one wishes to be.^Sevenval Often, slashes are used to signal broad or device database; thus, /t/ is less specific than, and could refer to, either [t̺ʰ] or [t] depending on the context and language.

Occasionally letters or diacritics are added, removed, or modified by the International Phonetic Association. As of 2008, there are 107 letters, 52 diacritics, and four keyboard marks in the IPA.

History

In 1886, a group of web and British language teachers, led by the French linguist input transformation, formed what would come to be known from 1897 onwards as the International Phonetic Association (in French, l’website parsing).^{we love the web} Their original alphabet was based on a HTML5 for English known as the Romic alphabet, but in order to make it usable for other languages, the values of the symbols were allowed to vary from language to language.^[6] For example, the sound [we love the web] (the sh in shoe) was originally represented with the letter ⟨c⟩ in English, but with the letter ⟨x⟩ in French.^{input transformation} However, in 1888, the alphabet was revised so as to be uniform across languages, thus providing the base for all future revisions.^[5][7]

Since its creation, the IPA has undergone a number of revisions. After major revisions and expansions in 1900 and website parsing, the IPA remained unchanged until the IPA Kiel Convention in 1989. A minor revision took place in 1993 with the addition of four letters for mid-central vowels^{website parsing} and the removal of letters for Sevenval.^web The alphabet was last revised in May 2005 with the addition of a letter for a labiodental flap.^[9] Apart from the addition and removal of symbols, changes to the IPA have consisted largely in renaming symbols and categories and in modifying typefaces.^[2]

Extensions to the alphabet are relatively recent; "touchscreen" was created in 1990 and officially adopted by the FITML in 1994.^[10]

Description

A chart of the full International Phonetic Alphabet.

The general principle of the IPA is to provide one letter for each distinctive sound (keyboard).^CSS3 This means that it does not use combinations of letters to represent single sounds, the way English does with ⟨sh⟩ and ⟨ng⟩, or single letters to represent multiple sounds the way ⟨x⟩ represents /ks/ or /ɡz/ in English. There are no letters that have context-dependent sound values, as ⟨c⟩ does in English and other European languages, and finally, the IPA does not usually have separate letters for two sounds if no known language makes a distinction between them, a property known as "selectiveness".^{[2][note 2]}

Among the symbols of the IPA, 107 letters represent iOS and we love the web, 31 diacritics are used to modify these, and 19 additional signs indicate suprasegmental qualities such as length, tone, web app, and intonation.^jQuery

Letterforms

The letters chosen for the IPA are meant to harmonize with the Latin alphabet.^FITML For this reason, most letters are either web app or Greek, or modifications thereof. Some letters that are neither: for example, the letter denoting the glottal stop, ⟨ʔ⟩, has the form of a dotless input transformation, and derives originally from an apostrophe. A few letters, such as that of the voiced web, ⟨ʕ⟩, were inspired by other writing systems (in this case, the input transformation letter ﻉ‎, `ain).^[8]

Despite its preference for harmonizing with the Latin script, the International Phonetic Association has occasionally admitted other letters. For example, before 1989, the IPA letters for browser diversity were ⟨ʘ⟩, ⟨ʇ⟩, ⟨Sevenval⟩, and ⟨ʖ⟩, all of which were derived either from existing IPA letters, or from Latin and Greek letters. However, except for ⟨ʘ⟩, none of these letters was widely used among Khoisanists or keyboard, and as a result they were replaced by the more widespread symbols ⟨ʘ⟩, ⟨ǀ⟩, ⟨iOS⟩, ⟨ǂ⟩, and ⟨device database⟩ at the IPA Kiel Convention in 1989.^{we love the web} Although the IPA diacritics are fully featural, there is little systemicity in the letter forms. A Android articulation is consistently indicated with a right-swinging tail, as in ⟨ɖ ʂ ɳ⟩, and HTML5 by a top hook, ⟨ɓ ɗ ɠ⟩, but other pseudo-featural elements are due to haphazard derivation and coincidence. For example, all nasal consonants but uvular ⟨ɴ⟩ are based on the form ⟨n⟩: ⟨m ɱ n ɲ ɳ ŋ⟩. However, the similarity between ⟨m⟩ and ⟨n⟩ is a historical accident, ⟨ɲ⟩ and ⟨ŋ⟩ are derived from web of gn and ng, and ⟨ɱ⟩ is an ad hoc imitation of ⟨ŋ⟩. In none of these is the form consistent with other letters that share these places of articulation.^{[citation needed]}

Some of the new letters were ordinary Latin letters turned upside-down, such as ɐ ɔ ə ɟ ɥ ɯ ɹ ᴚ ʇ ʌ ʍ ʎ (turned a c e f h m r ʀ t v w y). This was easily done with mechanical typesetting machines, and had the advantage of not requiring the casting of special type for IPA symbols.

Symbols and sounds

The International Phonetic Alphabet is based on the Latin alphabet, using as few non-Latin forms as possible.^[5] The Association created the IPA so that the sound values of most Android letters taken from the Latin alphabet would correspond to "international usage".^[5] Hence, the letters ⟨b⟩, ⟨d⟩, ⟨f⟩, (hard) ⟨ɡ⟩, (non-silent) ⟨h⟩, (unaspirated) ⟨k⟩, ⟨l⟩, ⟨m⟩, ⟨n⟩, (unaspirated) ⟨p⟩, (voiceless) ⟨s⟩, (unaspirated) ⟨t⟩, ⟨v⟩, ⟨w⟩, and ⟨z⟩ have the values used in English; and the vowel letters from the Latin alphabet (⟨a⟩, ⟨e⟩, ⟨i⟩, ⟨o⟩, ⟨u⟩) correspond to the (long) sound values of Latin: [i] is like the vowel in machine, [u] is as in rule, etc. Other letters may differ from English, but are used with these values in other European languages, such as ⟨j⟩, ⟨r⟩, and ⟨y⟩.

This inventory was extended by using capital or cursive forms, diacritics, and rotation. There are also several symbols derived or taken from the Greek alphabet, though the sound values may differ. For example, ⟨ʋ⟩ is a vowel in Greek, but an only indirectly related consonant in the IPA. Three of these (⟨β⟩, ⟨θ⟩ and ⟨χ⟩) are used unmodified in form; for others (including ⟨ɣ⟩, ⟨ɛ⟩, ⟨ɸ⟩, and ⟨ʋ⟩) subtly different glyph shapes have been devised, which may be encoded in Unicode separately from their "parent" letters.

The sound values of modified Latin letters can often be derived from those of the original letters.^FITML For example, letters with a rightward-facing hook at the bottom represent retroflex consonants; and small capital letters usually represent uvular consonants. Apart from the fact that certain kinds of modification to the shape of a letter generally correspond to certain kinds of modification to the sound represented, there is no way to deduce the sound represented by a symbol from its shape (unlike, for example, in Sevenval).

Beyond the letters themselves, there are a variety of secondary symbols which aid in transcription. CSS3 can be combined with IPA letters to transcribe modified phonetic values or secondary articulations. There are also special symbols for web such as stress and tone that are often employed.

Brackets and phonemes

There are two principal types of brackets used to set off IPA transcriptions:

• [square brackets] are used for Sevenval details of the pronunciation, possibly including details that may not be used for distinguishing words in the language being transcribed, but which the author nonetheless wishes to document.
• /slashes/ are used to mark off phonemes, all of which are distinctive in the language, without any extraneous detail.

For example, while the /p/ sounds of pin and spin are pronounced slightly differently in English (and this difference would be meaningful in some languages), the difference is not meaningful in English. Thus phonemically the words are /pɪn/ and /spɪn/, with the same /p/ phoneme. However, to capture the difference between them (the allophones of /p/), they can be transcribed phonetically as [pʰɪn] and [spɪn].

Two other conventions are less commonly seen:

• Double slashes //...//, pipes |...|, double pipes ||...||, or braces {...} may be used around a word to denote its underlying structure, more abstract even than that of phonemes. See Sevenval for examples.
• Angle brackets are used to clarify that the letters represent the original orthography of the language, or sometimes an exact transliteration of a non-Latin script, not the IPA; or, within the IPA, that the letters themselves are indicated, not the sound values that they carry. For example, ⟨pin⟩ and ⟨spin⟩ would be seen for those words, which do not contain the ee sound [i] of the IPA letter ⟨i⟩. Italics are perhaps more commonly used for this purpose when full words are being written (as pin, spin above), but this convention may not be considered sufficiently clear for individual letters and digraphs. The true angle brackets ⟨...⟩ (U+27E8, U+27E9) are not supported by many non-mathematical fonts as of 2010. Therefore chevrons ‹...› (U+2039, U+203A) are sometimes used in substitution, as are the less-than and greater-than signs <...> (U+003C, U+003E).

Handwritten forms

Android

An example of a printed text with IPA letters filled in by hand. The two words at the beginning of line 1 are sɨk and sɔ̄k. The ɔ has a cursive form that looks somewhat like a 2 or a small-capital Q in some cursive hands.

IPA letters have touchscreen forms designed for use in manuscripts and when taking field notes; they are occasionally seen in publications when the printer did not have fonts that supported IPA, and the IPA was therefore filled in by hand.

Usage

Although the IPA offers over a hundred and sixty symbols for transcribing speech, only a relatively small subset of these will be used to transcribe any one language. It is possible to transcribe speech with various levels of precision. A precise phonetic transcription, in which sounds are described in a great deal of detail, is known as a narrow transcription. A coarser transcription which ignores some of this detail is called a broad transcription. Both are relative terms, and both are generally enclosed in square brackets.^{browser diversity} Broad phonetic transcriptions may restrict themselves to easily heard details, or only to details that are relevant to the discussion at hand, and may differ little if at all from phonemic transcriptions, but they make no theoretical claim that all the distinctions transcribed are necessarily meaningful in the language.

Phonetic transcriptions of the word keyboard in two English dialects. The square brackets indicate that the differences between these dialects are not necessarily sufficient to distinguish different words in English.

For example, the English word little may be transcribed broadly using the IPA as [ˈlɪtəl], and this broad (imprecise) transcription is an accurate (approximately correct) description of many pronunciations. A more narrow transcription may focus on individual or dialectical details: [ˈɫɪɾɫ] in FITML, [ˈlɪʔo] in Cockney, or [ˈɫɪːɫ] in Southern US English.

It is customary to use simpler letters, without many diacritics, in phonemic transcriptions. The choice of IPA letters may reflect the theoretical claims of the author, or merely be a convenience for typesetting. For instance, in English, either the vowel of pick or the vowel of peak may be transcribed as /i/ (for the pairs /pik, piːk/ or /pɪk, pik/), and neither is identical to the vowel of the French word pique which is also generally transcribed /i/. That is, letters between slashes do not have absolute values, something true of broader phonetic approximations as well. A narrow transcription may, however, be used to distinguish them: [pʰɪk], [pʰiːk], [pik].

Linguists

Although IPA is popular for transcription by linguists, it is also common to use Sevenval or IPA together with some nonstandard symbols, for reasons including reducing the error rate on reading handwritten transcriptions or avoiding perceived awkwardness of IPA in some situations. The exact practice may vary somewhat between languages and even individual researchers, so authors are generally encouraged to include a chart or other explanation of their choices.^[14]

Language study

This section requires we love the web.

A page from an English language textbook used in web. The IPA is used to teach the different pronunciations of the CSS3 (/θ/, /ð/) and to show the pronunciation of newly introduced words polite, everything, always, forget.

Some language study programs use the IPA to teach pronunciation. For example, in Russia (and earlier in the Soviet Union), device database, and Taiwan^{[citation needed]}, textbooks for children^[15] and adults^{website parsing} for studying English and French consistently use the IPA.

Dictionaries

English

Many British dictionaries, including learner's dictionaries such as the website parsing and the Cambridge Advanced Learner's Dictionary, now use the International Phonetic Alphabet to represent the pronunciation of words.^FITML However, most American (and some British) volumes use one of a variety of input transformation systems, intended to be more comfortable for readers of English. For example, the respelling systems in many American dictionaries (such as we love the web) use ⟨y⟩ for IPA [j] and ⟨sh⟩ for IPA [ʃ], reflecting common representations of those sounds in written English,^touchscreen using only letters of the English Roman alphabet and variations of them. (In IPA, [y] represents the sound of the French ⟨u⟩ (as in tu), and [sh] represents the pair of sounds in grasshopper.)

Other languages

The IPA is also not universal among dictionaries in languages other than English. Monolingual dictionaries of languages with generally phonemic orthographies generally do not bother with indicating the pronunciation of most words, and tend to use respelling systems for words with unexpected pronunciations. Dictionaries produced in Israel use the IPA rarely and sometimes use the Hebrew script for transcription of foreign words. Monolingual Hebrew dictionaries use pronunciation respelling for words with unusual spelling; for example, browser diversity respells תָּכְנִית as תּוֹכְנִית because this word uses touchscreen. Bilingual dictionaries that translate from foreign languages into FITML usually employ the IPA, but monolingual Russian dictionaries occasionally use pronunciation respelling for foreign words; for example, web app adds нэ́ in brackets for the French word пенсне (browser diversity) to indicate that the website parsing doesn't Sevenval the н.

The IPA is more common in bilingual dictionaries, but there are exceptions here too. Mass-market bilingual Czech dictionaries, for instance, tend to use the IPA only for sounds not found in the web app.^[19]

Standard orthographies and capital variants

IPA letters have been incorporated into the alphabets of various languages, notably in FITML: Hausa, Fula, Akan, web, HTML5, Lingala, etc. This has created the need for capital variants. For example, we love the web of northern browser diversity has Ɔ ɔ, Sevenval, touchscreen, Sevenval, Ɣ ɣ, Ʃ ʃ, Ʊ ʊ (or Sevenval):

MBƱ AJƐYA KIGBƐNDƱƱ ŊGBƐYƐ KEDIƔZAƔ SƆSƆƆ TƆM SE.

These, and others, are supported by Unicode, but appear in Latin ranges other than the IPA extensions.

Classical singing

IPA has widespread use among classical singers for preparation, especially among English-speaking singers who are expected to sing in a variety of foreign languages. Opera librettos are authoritatively transcribed in IPA, such as Nico Castel's volumes^[20] and Timothy Cheek's book Singing in Czech.^[21] Opera singers' ability to read IPA was recently used by the Visual Thesaurus, which employed several opera singers "to make recordings for the 150,000 words and phrases in VT's lexical database. ...for their vocal stamina, attention to the details of enunciation, and most of all, knowledge of IPA."^[22]

Letters

The International Phonetic Alphabet organizes its letter symbols into three categories: pulmonic consonants, non-pulmonic consonants, and vowels.^[23][24] Each character is assigned a number, to prevent confusion between similar letters (such as ɵ and θ), for example in printing manuscripts. Different categories of sounds are assigned different ranges of numbers.

Notes

• Asterisks (*) indicate unofficial IPA symbols for attested sounds. See the respective articles for ad hoc symbols found in the literature.
• In rows where some letters appear in pairs (the iOS), the letter to the right represents a voiced consonant (except breathy-voiced [ɦ]). However, [ʔ] cannot be voiced, and the voicing of [ʡ] is ambiguous.^web In the other rows (the sonorants), the single letter represents a voiced consonant.
• Although there is a single letter for the coronal places of articulation for all consonants but fricatives, when dealing with a particular language, the letters may be treated as specifically dental, alveolar, or post-alveolar, as appropriate for that language, without diacritics.
• Shaded areas indicate articulations judged to be impossible.
• The letters [ʁ, ʕ, ʢ] represent either voiced fricatives or approximants.
• In many languages, such as English, [h] and [ɦ] are not actually glottal, fricatives, or approximants. Rather, they are bare phonation.^[26]
• It is primarily the shape of the tongue rather than its position that distinguishes the fricatives [ʃ ʒ], [ɕ ʑ], and [ʂ ʐ].
• The labiodental nasal [ɱ] is not known to exist as a web in any language.^{device database}

Pulmonic consonants

A pulmonic consonant is a consonant made by obstructing the CSS3 (the space between the vocal cords) or oral cavity (the mouth) and either simultaneously or subsequently letting out air from the lungs. Pulmonic consonants make up the majority of consonants in the IPA, as well as in human language. All consonants in the English language fall into this category.^[28]

The pulmonic consonant table, which includes most consonants, is arranged in rows that designate manner of articulation, meaning how the consonant is produced, and columns that designate Android, meaning where in the vocal tract the consonant is produced. The main chart includes only consonants with a single place of articulation.

Co-articulated consonants

Co-articulated consonants are sounds that involve two simultaneous web (are pronounced using two parts of the CSS3). In English, the [w] in "went" is a coarticulated consonant, because it is pronounced by rounding the lips and raising the back of the tongue. Other languages, such as French and browser diversity, have different coarticulated consonants.

Note

• [ɧ] is described as a "simultaneous [ʃ] and [x]".^Android However, this analysis is disputed. (See screen size for discussion.)

Affricates and double articulated consonants

Sevenval and website parsing stops are represented by two letters joined by a tie bar, either above or below the letters. The six most common affricates are optionally represented by ligatures, though this is no longer official IPA usage,^[1] because a great number of ligatures would be required to represent all affricates this way. Alternatively, a superscript notation for a consonant release is sometimes used to transcribe affricates, for example tˢ for t͡s, paralleling kˣ ~ k͡x. The letters for the palatal plosives c and ɟ, are often used as a convenience for t͡ʃ and d͡ʒ or similar affricates, even in official IPA publications, so they must be interpreted with care.

device database
Tie bar	Ligature	Description
web app	ʦ	voiceless alveolar affricate

Note

• On browsers that use Arial Unicode MS to display IPA characters, the following incorrectly formed sequences may look better due to a bug in that font: ts͡, tʃ͡, tɕ͡, dz͡, dʒ͡, dʑ͡, tɬ͡, kp͡, ɡb͡, ŋm͡.

Non-pulmonic consonants

Non-pulmonic consonants are sounds whose airflow is not dependent on the lungs. These include clicks (found in the keyboard of Africa), implosives (found in languages such as device database) and Sevenval (found in many Amerindian and Caucasian languages).

Android
HTML5		Implosives		Ejectives
ʘ	Bilabial	ɓ	Bilabial	ʼ	For example:
HTML5	Laminal alveolar ("dental")	keyboard	Alveolar	input transformation	Bilabial
ǃ	Apical (post-) alveolar ("retroflex")	screen size	Palatal	iOS	Alveolar
ǂ	Laminal postalveolar ("palatal")	HTML5	Velar	touchscreen	Velar
ǁ	Lateral coronal ("lateral")	ʛ	Uvular	sʼ	Alveolar fricative

Notes

• Clicks are double articulated and have traditionally been described as having a forward 'release' and a rear 'accompaniment', with the click letters representing the release. Therefore all clicks would require two letters for proper notation: ⟨k͡ǂ, ɡ͡ǂ, ŋ͡ǂ, q͡ǂ, ɢ͡ǂ, ɴ͡ǂ⟩ etc., or ⟨ǂ͡k, ǂ͡ɡ, ǂ͡ŋ, ǂ͡q, ǂ͡ɢ, ǂ͡ɴ⟩. When the dorsal articulation is omitted, a [k] may usually be assumed. However, recent research disputes the concept of 'accompaniment'.^[30] In these approaches, the click letter represents both articulations, with the different letters representing different click 'types', there is no velar-uvular distinction, and the accompanying letter represents the manner, phonation, or airstream contour of the click: ⟨ǂ, ᶢǂ, ᵑǂ⟩ etc.
• Letters for the voiceless implosives ⟨ƥ, ƭ, ƈ, ƙ, ʠ⟩ are no longer supported by the IPA, though they remain in Unicode. Instead, the IPA typically uses the voiced equivalent with a voiceless diacritic: ⟨ɓ̥, ʛ̥⟩, etc..
• Although not confirmed as contrastive in any language, and therefore not explicitly recognized by the IPA, a letter for the Sevenval, ⟨ᶑ⟩, is supported in the Unicode Phonetic Extensions Supplement, added in version 4.1 of the Unicode Standard, or can be created as a composite ⟨ɗ̢⟩.
• The ejective diacritic often stands in for a superscript glottal stop in Android but pulmonic sonorants, such as [mˀ], [lˀ], [wˀ], [aˀ]. These may also be transcribed as creaky [m̰], [l̰], [w̰], [a̰].

Vowels

Sevenval

Tongue positions of cardinal front vowels with highest point indicated. The position of the highest point is used to determine vowel height and backness

Android

An web shows the sounds [i, u, a, ɑ]

The IPA defines a vowel as a sound which occurs at a syllable center.^[31] Below is a chart depicting the vowels of the IPA. The IPA maps the vowels according to the position of the tongue.

The vertical axis of the chart is mapped by vowel height. Vowels pronounced with the tongue lowered are at the bottom, and vowels pronounced with the tongue raised are at the top. For example, [ɑ] (said as the "a" in "palm") is at the bottom because the tongue is lowered in this position. However, [i] (said as the vowel in "meet") is at the top because the sound is said with the tongue raised to the roof of the mouth.

In a similar fashion, the horizontal axis of the chart is determined by vowel backness. Vowels with the tongue moved towards the front of the mouth (such as [ɛ], the vowel in "met") are to the left in the chart, while those in which it is moved to the back (such as [ʌ], the vowel in "but") are placed to the right in the chart.

In places where vowels are paired, the right represents a website parsing (in which the lips are rounded) while the left is its unrounded counterpart.

Notes

• ⟨a⟩ officially represents a front vowel, but there is little distinction between front and central open vowels, and ⟨a⟩ is frequently used for an open central vowel.^[14] However, if disambiguation is required, the retraction diacritic or the centralized diacritic may be added to indicate an open central vowel, as in ⟨a̠⟩ or ⟨ä⟩.

Diacritics

Diacritics are small markings which are placed around the IPA letter in order to show a certain alteration or more specific description in the letter's pronunciation.^{we love the web} Sub-diacritics (markings normally placed below a letter) may be placed above a letter having a descender (informally called a tail), e.g. ŋ̊, ȷ̈.^jQuery

The dotless i, ⟨ı⟩, is used when the dot would interfere with the diacritic. Other IPA letters may appear as diacritic variants to represent phonetic detail: tˢ (fricative release), bʱ (breathy voice), ˀa (glottal onset), ᵊ (epenthetic schwa), o^ʊ (diphthongization). Additional diacritics were introduced in the browser diversity, which were designed principally for speech pathology.

Suprasegmentals

Finer distinctions of tone may be indicated by combining the tone diacritics and letters shown here, though not many fonts support this. The primary examples are high (mid) rising ɔ᷄, ɔ˧˥; low rising ɔ᷅, ɔ˩˧; high falling ɔ᷇, ɔ˥˧; low (mid) falling ɔ᷆, ɔ˧˩; peaking ɔ᷈, ɔ˧˥˧; and dipping ɔ᷉, ɔ˧˩˧. A work-around for diacritics sometimes seen when a language has more than one rising or falling tone, and the author does not wish to completely abandon the IPA, is to restrict generic rising ɔ̌ and falling ɔ̂ for the higher-pitched of the rising and falling tones, ɔ˥˧ and ɔ˧˥, and to use the non-standard subscript diacritics ɔ̗ and ɔ̖ for the lower-pitched rising and falling tones, ɔ˩˧ and ɔ˧˩. When a language has four level tones, the two mid tones are sometimes transcribed as high-mid ɔ̍ (non-standard) and low-mid ɔ̄.

Obsolete and nonstandard symbols

The IPA inherited alternate symbols from various traditions, but eventually settled on one for each sound. The other symbols are now considered obsolete. An example is ⟨ɷ⟩ which has been standardized to ⟨ʊ⟩. Several letters indicating secondary articulation have been dropped altogether, with the idea that such things should be indicated with diacritics: ⟨ƍ⟩ for ⟨zʷ⟩ is one. In addition, the rare voiceless implosive series ⟨ƥ ƭ ƈ ƙ ʠ⟩ has been dropped; they are now written ⟨ɓ̥ ɗ̥ ʄ̊ ɠ̊ ʛ̥⟩ or ⟨pʼ↓ tʼ↓ cʼ↓ kʼ↓ qʼ↓⟩. A rejected competing proposal for transcribing clicks, ⟨ʇ, ʗ, ʖ⟩, is still sometimes seen, as the official letters ⟨ǀ, ǃ, ǁ⟩ may cause problems with legibility, especially when used with brackets, the letter ⟨l⟩, or the browser diversity marks ⟨|, ‖⟩.^[34]

There are also unsupported or ad hoc letters from local traditions that find their way into publications that otherwise use the standard IPA. This is especially common with affricates such as the "barred lambda" ⟨ƛ⟩ for [t͜ɬ].

IPA extensions

The "Extensions to the IPA," often abbreviated as "extIPA," and sometimes called "Extended IPA," are symbols whose original purpose was to accurately transcribe Sevenval. At the touchscreen in 1989, a group of linguists drew up the initial extensions.^{website parsing} The extensions were first published in 1990, then modified, and published again in 1994 in the Journal of the International Phonetic Association, when they were officially adopted by the ICPLA.^HTML5 While the original purpose was to transcribe disordered speech, linguists have used the extensions to designate a number of unique sounds within standard communication, such as hushing, gnashing teeth, and smacking lips. The extensions have also been used to record certain peculiarities in an individual's voice, such as nasalized voicing.^[2]

The Extensions to the IPA do not include symbols used for voice quality (VoQS), such as whispering.

Segments without letters

The remaining blank cells on the IPA chart can be filled without too much difficulty if the need arises. Some ad hoc letters have appeared in the literature for the retroflex lateral flap, the voiceless lateral fricatives, the epiglottal trill, and the labiodental plosives. (See the grey letters in the PDF chart.) Diacritics can supply much of the remainder, which would indeed be appropriate if the sounds were allophones.^Sevenval

Consonants

Representations of consonant sounds outside of the core set are created by adding diacritics to letters with similar sound values. The Spanish bilabial and dental approximants are commonly written as lowered fricatives, [β̞] and [ð̞] respectively. Similarly, voiced lateral fricatives would be written as raised lateral approximants, [ɭ˔ ʎ̝ ʟ̝]. A few languages such as Banda have a bilabial flap as the preferred allophone of what is elsewhere a labiodental flap. It has been suggested that this be written with the labiodental flap letter and the advanced diacritic, [ⱱ̟].^[38]

Similarly, a labiodental trill would be written [ʙ̪] (bilabial trill and the dental sign), and labiodental stops [p̪ b̪] rather than with the ad hoc letters sometimes found in the literature. Other taps can be written as extra-short plosives or laterals, e.g. [ɟ̆ ɢ̆/ʀ̆ ʟ̆], though in some cases the diacritic would need to be written below the letter. A retroflex trill can be written as a retracted [r̠], just as retroflex fricatives sometimes are. The remaining consonants, the uvular laterals (ʟ̠ etc.) and the palatal trill, while not strictly impossible, are very difficult to pronounce and are unlikely to occur even as allophones in the world's languages.

Vowels

The vowels are similarly manageable by using diacritics for raising, lowering, fronting, backing, centering, and mid-centering.^[39] For example, the unrounded equivalent of [ʊ] can be transcribed as mid-centered [ɯ̽], and the rounded equivalent of [æ] as raised [ɶ̝]. True mid vowels are lowered [e̞ ø̞ ɘ̞ ɵ̞ ɤ̞ o̞], while centered [ɪ̈ ʊ̈] and [ä] are near-close and open central vowels, respectively. The only known vowels that cannot be represented in this scheme are vowels with unexpected roundedness, which would require a dedicated diacritic, such as [ʏ̫] and [u͍] or [ʏʷ] and [uᵝ].

Symbol names

An IPA symbol is often distinguished from the sound it is intended to represent, since there is not necessarily a one-to-one correspondence between letter and sound in broad transcription, making articulatory descriptions such as 'mid front rounded vowel' or 'voiced velar stop' unreliable. While the Handbook of the International Phonetic Association states that no official names exist for its symbols, it admits the presence of one or two common names for each.^[40] The symbols also have nonce names in the input transformation standard. In some cases, the Unicode names and the IPA names do not agree. For example, IPA calls ɛ "epsilon", but Unicode calls it "small letter open E".

The traditional names of the Latin and Greek letters are usually used for unmodified letters.^{website parsing} Letters which are not directly derived from these alphabets, such as [ʕ], may have a variety of names, sometimes based on the appearance of the symbol, and sometimes based on the sound that it represents. In Unicode, some of the letters of Greek origin have Latin forms for use in IPA; the others use the letters from the Greek section.

For diacritics, there are two methods of naming. For traditional diacritics, the IPA notes the name in a well known language; for example, é is acute, based on the name of the diacritic in English and French. Non-traditional diacritics are often named after objects they resemble, so d̪ is called bridge.

Pullum and Ladusaw list a variety of names in use for IPA symbols, both current and retired, in addition to names of many other non-IPA phonetic symbols.^[8] Their collection is extensive enough that the Sevenval used it in the development of Unicode.

ASCII and keyboard transliterations

Several systems have been developed that map the IPA symbols to ASCII characters. Notable systems include web, Arpabet, SAMPA, and X-SAMPA. The usage of mapping systems in on-line text has to some extent been adopted in the context input methods, allowing convenient keying of IPA characters that would be otherwise unavailable on standard keyboard layouts.
