Interdental consonants are produced by placing the tip of the tongue between the upper and lower front teeth. That differs from typical dental consonants , which are articulated with the tongue against the back of the upper incisors. No language is known to contrast interdental and dental consonants.

38-489: Interdental consonants may be transcribed with the extIPA subscript, plus superscript bridge, as in ⟨ n̪͆ t̪͆ d̪͆ θ̪͆ ð̪͆ r̪͆ ɹ̪͆ l̪͆ ɬ̪͆ ɮ̪͆ ⟩, if precision is required, but it is more common to transcribe them as advanced alveolars, as in ⟨ n̟ t̟ d̟ θ̟ ð̟ r̟ ɹ̟ l̟ ɬ̟ ɮ̟ ⟩. Interdental consonants are rare cross-linguistically. Interdental realisations of otherwise-dental or alveolar consonants may occur as idiosyncrasies or as coarticulatory effects of

76-481: A neighbouring interdental sound. The most commonly-occurring interdental consonants are the non- sibilant fricatives (sibilants may be dental but do not appear as interdentals). Apparently, interdentals do not contrast with dental consonants in any language. Voiced and voiceless interdental fricatives [ð̟, θ̟] appear in American English as the initial sounds of words like 'then' and 'thin'. In British English ,

114-424: A partial degree of voicing at the beginning or end of the sound. For the latter, both parentheses mean the sound is (de)voiced in the middle, while the single parentheses mean complete (de)voicing at the beginning or end of the sound. The implication is that such voicing or devoicing is atypical of the language being spoken. For example, ⟨ z̥ ⟩ would be used for the usual devoicing or partial devoicing of

152-417: A subset of extIPA. Several letters and superscript forms were added to Unicode 14 and 15. They are included in the free Gentium Plus and Andika fonts. The extIPA has widened the use of some of the regular IPA symbols, such as [ʰp] for pre-aspiration and [tʶ] for uvularization, and has added some new ones. Some of these extIPA diacritics are occasionally used for non-disordered speech, for example for

190-510: A target sound has not been reached – for example, [ˈtʃɪᵏən] for an instance of the word 'chicken' where the /k/ is incompletely articulated. However, due to the ambiguous meaning of superscripting in the IPA, this is not a convention supported by the ICPLA. An unambiguous transcription would mark the consonant more specifically as weakened ( [ˈtʃɪk͉ən] ) or silent ( [ˈtʃɪ(k)ən] ). A sample transcription of

266-419: Is a common topic in speech pathology, though ⟨ s̪ z̪ ⟩ occur in non-pathological speech in some languages. Any IPA letter may be used in superscript form as a diacritic, to indicate the onset, release or 'flavor' of another letter. In extIPA, this is provided specifically for the fricative release of a plosive. For example, ⟨ k𐞜 ⟩ is [k] with a lateral-fricative release (similar to

304-450: Is added here. Several new columns appear as well, though the linguolabial column is the result of a standard-IPA diacritic. Dorso-velar and velo-dorsal are combined here, as are upper and lower alveolar. The customary use of superscript IPA letters is formalized in the extIPA, specifically for fricative releases of plosives, as can be seen in the lower-left of the full chart. Speech pathologists also often use superscripting to indicate that

342-425: Is also IPA usage. Sometimes the obscuring noise will be indicated instead, as in ⸨cough⸩ or ⸨knock⸩, as in the illustrative transcription below; this notation may be used for extraneous noise that does not obscure speech, but which the transcriber nonetheless wishes to notate (e.g. because someone says 'excuse me' after coughing, or verbally responds to the knock on the door, and the noise is thus required to understand

380-465: Is also reported in some parts of the United States, particularly Utah. There are two primary articulations of the approximant /r/ : apical (with the tip of the tongue approaching the alveolar ridge or even curled back slightly) and domal (with a centralized bunching of the tongue known as molar r or sometimes bunched r or braced r ). Peter Ladefoged wrote: "Many BBC English speakers have

418-550: Is most commonly observed in quick changes from the blade to the tip of the tongue (laminal to apical) in plosives and fricatives, such as [t̪͢t] and [t͢θ] , or vice versa, but is not limited to that; the consonants may also be labial or dorsal, e.g. [ɸ͢f] and [k͢q] . The slit-grooved distinction of the channel shape of front fricatives may be handled with these diacritics, with for example ⟨ s̪ z̪ ⟩ for grooved (sibilant) dental fricatives, and ⟨ θ͇ ð͇ ⟩ for ungrooved (non-sibilant) aveolar fricatives. This

456-411: Is sometimes found in IPA transcription, though in IPA the diacritic has also been used for apical-retroflex articulation. The Extended IPA has adopted bracket notation from conventions transcribing discourse. Parentheses are used to indicate mouthing (silent articulation), as in the common silent sign to hush (ʃːː) . Parentheses are also used to indicate silent pauses, for example (...); the length of

494-473: Is uncertain. For example, ⓚ indicates that the segment is judged to probably be [k] . This is effectively a copy-edit mark , and may be elongated into an oval for longer strings of symbols. This was illustrated in the 1997 edition of the chart, where the circle was typeset as ( ̲̅) and longer strings as e.g. (a̲̅a̲̅a̲̅). There is no way to typeset this in Unicode that does not require spurious characters between

532-422: Is used for an English molar-r , as opposed to ⟨ ɹ̺ ⟩ for an apical r; these articulations are indistinguishable in sound and so are rarely identified in non-disordered speech. Sounds restricted to disordered speech include velopharyngeals , nasal fricatives (a.k.a. nareal fricatives) and some of the percussive consonants . Sounds sometimes found in the world's languages that do not have symbols in

570-472: The Bauchi languages of Nigeria. Interdental [ɮ̟] occurs in some dialects of Amis . Mapuche has interdental [n̟] , [t̟] , and [l̟] . In most Indigenous Australian languages , there is a series of "dental" consonants, written th , nh , and (in some languages) lh . They are always laminal (pronounced by touching with the blade of the tongue) but may be formed in one of three different ways, depending on

608-593: The International Phonetic Alphabet for the phonetic transcription of disordered speech . Some of the symbols are used for transcribing features of normal speech in IPA transcription, and are accepted as such by the International Phonetic Association . Many sounds found only in disordered speech are indicated with diacritics, though an increasing number of dedicated letters are used as well. Special letters are included to transcribe

646-593: The South-East of England , particularly London . That has also been reported to be an extremely rare realization of /r/ in New Zealand English and in the speech of younger speakers of Singapore English . The /r/ realization may not always be labiodental since bilabial realizations have also been reported. R-labialization leads to pronunciations such as these: However, the replacement of /r/ by some kind of labial approximant may also occur caused by

684-472: The phoneme /r/ in the English language has many variations in different dialects . Depending on dialect, /r/ has at least the following allophones in varieties of English around the world: In most British dialects /r/ is labialized [ɹ̠ʷ] in many positions, as in reed [ɹʷiːd] and tree [tɹ̥ʷiː] ; in the latter case, the /t/ may be slightly labialized as well. In many dialects, /r/ in

722-478: The West Country and some parts of Lancashire and the far north). Thus, a rhotic accent pronounces marker as /ˈmɑrkər/ , and a non-rhotic accent pronounces the same word as /ˈmɑːkə/ . In rhotic accents , when /r/ is not followed by a vowel phoneme, it generally surfaces as r-coloring of the preceding vowel or its coda: nurse [nɝs] , butter [ˈbʌtɚ] . R -labialization, which should not be confused with

760-469: The basic IPA include denasals , the sublaminal percussive , palatal and velar lateral fricatives , and fricatives that are simultaneously lateral and sibilant. ExtIPA was revised and expanded in 2015; the new symbols were added to Unicode in 2021. The non-IPA letters found in the extIPA are listed in the following table. VoQS letters may also be used, as in ⟨ ↀ͡r̪͆ ⟩ for a buccal interdental trill (a raspberry ), as VoQS started off as

798-434: The cluster /dr/ , as in dream , is realized as a postalveolar fricative [ɹ̠˔] or less commonly alveolar [ɹ̝] . In /tr/ , as in tree , it is a voiceless postalveolar fricative [ɹ̠̊˔] or less commonly alveolar [ɹ̝̊] . In England, while the approximant has become the most common realization, /r/ may still be pronounced as a voiceless tap [ɾ̥] after /θ/ (as in thread ). Tap realization of /r/ after /θ/

836-585: The consonants are more likely to be dental [ð, θ] . An interdental [l̟] occurs in some varieties of Italian , and it may also occur in some varieties of English though the distribution and the usage of interdental [l̟] in English are not clear. Interdental approximant s [ð̞] are found in about a dozen Philippine languages , including Kagayanen ( Manobo branch), Karaga Mandaya ( Mansakan branch), Kalagan ( Mansakan branch), Southern Catanduanes Bicolano , and several varieties of Kalinga , as well as in

874-404: The intervening text. The VoQS conventions use similar notation for voice quality. These may be combined, for example with VoQS ⟨F⟩ for 'falsetto': or Three rows appear in the extIPA chart that do not occur in the IPA chart: "fricative lateral + median" (simultaneous grooved and lateral frication), " fricative nasal " (a.k.a. nareal fricative) and " percussive ". A denasal row

They are apical interdental [t̺͆~d̺͆ n̺͆ l̺͆] with the tip of the tongue visible between the teeth, as in th in American English; laminal interdental [t̻͆~d̻͆ n̻͆ l̻͆] with the tip of the tongue down behind the lower teeth, so that the blade is visible between the teeth; and denti-alveolar [t̻̪~d̻̪ n̻̪ l̻̪] , that is, with both

950-477: The language, while ⟨ z̥᪽ ⟩ would indicate that the transcriber found the devoicing to be atypical, as in pathological speech. Similarly, ⟨ z̥᫃ ⟩ would indicate atypical devoicing at the beginning of the segment. Altering the position of a diacritic relative to the letter indicates that the phonation begins before the consonant or vowel does or continues beyond it. The voiceless ring and other phonation diacritics can be used in

988-401: The letters (as here), but it may be graphically approximated with an unused set of brackets, such as ⦇aaa⦈. Curly brackets with Italian musical terms are used for phonation and prosodic notation, such as [{ falsetto ˈhɛlp falsetto }] and terms for the tempo and dynamics of connected speech. These are subscripted within a {curly brace} notation to indicate that they are comments on

1026-438: The pause may be indicated, as in (2.3 sec). A very short (.) may be used to indicate an absence of co-articulation between adjacent segments, for instance [t(.)weɫv̥] rather than [tʷw̥eɫv̥] . Double parentheses indicate that transcription is uncertain because of extraneous noise or speech, as when one person talks over another. As much detail as possible may be included, as in ⸨2 syll.⸩ or ⸨2σ⸩ for two obscured syllables. This

1064-447: The rounding of initial /r/ described above, is a process occurring in certain dialects of English, particularly some varieties of Cockney , in which the /r/ phoneme is realized as a labiodental approximant [ʋ] , in contrast to an alveolar approximant [ɹ] . The use of labiodental /r/ is commonly stigmatized by prescriptivists . However, its use is growing in many accents of British English . Most speakers who do so are from

1102-470: The same way if needed. For example, ⟨ p˳a ⟩ indicates that voicelessness continues past the [p] , more or less equivalent to ⟨ pʰa ⟩. Other extIPA diacritics are: Diacritics may be placed within parentheses as the voicing diacritics are above. For example, ⟨ m͊᪻ ⟩ indicates a partially denasalized [m] . The arrow for sliding articulation was first used for [wɑət̪s̪͢θ] for 'watch' and [z̪͢ðɪpʊə] for 'zipper'. It

1140-445: The segment (pre- and post-voicing etc. ). The following are examples; in principle, any IPA or extIPA diacritic may be parenthesized or displaced in this manner. The transcriptions for partial voicing and devoicing may be used in either the sense of degrees of voicing or in the sense that the voicing is discontinuous. For the former, both parentheses indicate the sound is mildly (partially) voiced throughout, and single parentheses mean

1178-474: The speech of people with lisps and cleft palates . The extIPA repeats several standard-IPA diacritics that are unfamiliar to most people but transcribe features that are common in disordered speech. These include preaspiration ⟨ ʰ◌ ⟩, linguolabial ⟨ ◌̼ ⟩, laminal fricatives [s̻, z̻] , and ⟨ * ⟩ for a sound (segment or feature) with no available symbol (letter or diacritic).

An empty circle, ◯, is used for an indeterminate segment, ◯  σ  an indeterminate syllable, Ⓒ a segment identifiable only as a consonant, etc. Full capital letters, such as C in Ⓒ, are used as wild-cards for certain categories of sounds , and may combine with IPA and extIPA diacritics. For example, ◯   P̥   indicates an undetermined or indeterminate voiceless plosive. Regular IPA and extIPA letters may also be circled to indicate that their identification

The extension to the IPA recommends the use of the IPA diacritics for "apical" and "centralized", as in ⟨ ɹ̺, ɹ̈ ⟩, to distinguish apical and domal articulations in transcription. However, this distinction has little or no perceptual consequence, and may vary idiosyncratically between individuals. English accents around
