Triphthong

Last updated

In phonetics, a triphthong ( UK: /ˈtrɪfθɒŋ,ˈtrɪpθɒŋ/ , US: /-θɔːŋ/ ) (from Greek τρίφθογγος, "triphthongos", literally "with three sounds," or "with three tones") is a monosyllabic vowel combination involving a quick but smooth movement of the articulator from one vowel quality to another that passes over a third. While "pure" vowels, or monophthongs, are said to have one target articulator position, diphthongs have two and triphthongs three.

Contents

Triphthongs are not to be confused with disyllabic sequences of a diphthong followed by a monophthong, as in German Feuer [ˈfɔʏɐ] 'fire', where the final vowel is longer than those found in triphthongs.

Examples

Triphthongs that feature close elements that are typically analyzed as /j/ and /w/ in phonology are not listed. For instance, the Polish word łój [wuj] 'tallow' is typically analyzed as /CVC/ - a sequence of a consonant followed by a vowel and another consonant. This is because the palatal approximant is resyllabified in some inflected forms, such as łojami [wɔˈjami] (instr. pl.), and also because /w/ occurs word-finally after a consonant just like /l/ does (compare przemysł [ˈpʂɛmɨsw] 'industry' with Przemyśl [ˈpʂɛmɨɕl] 'Przemyśl'), which means that both of them behave more like consonants than vowels.

On the other hand, [ɪ̯, i̯, ʊ̯, u̯] are not treated as phonetic consonants when they arise from vocalization of /l/, /v/ or /ɡ/ as they do not share almost all of their features with those three.

First segment is the nucleus

Bernese German

Bernese German has the following triphthongs:

  • [iə̯u̯] as in Gieu 'boy'
  • [yə̯u̯] as in Gfüeu 'feeling'
  • [uə̯u̯] as in Schueu 'school'

They have arisen due to the vocalization of /l/ in the syllable coda; compare the last two with Standard German Gefühl [ɡəˈfyːl] and Schule [ˈʃuːlə] , the last one with a schwa not present in the Bernese word.

Danish

Danish has the following thriphthongs: [1]

  • [ɛɐ̯u̯] as in færge 'ferry'
  • [iɐ̯u̯] as in hvirvle 'to whirl'
  • [œ̞ɐ̯u̯] as in Børge, a given name
  • [uɐ̯u̯] as in spurv 'sparrow'

English

In British Received Pronunciation, and most other non-rhotic (r-dropping) varieties of English, monosyllabic triphthongs with R are optionally distinguished from sequences with disyllabic realizations:

  • [aʊ̯ə̯] as in hour (compare with disyllabic "shower" [aʊ̯.ə])
  • [aɪ̯ə̯] as in fire (compare with disyllabic "higher" [aɪ̯.ə])
  • [ɔɪ̯ə̯] as in "loir" (compare with final disyllabic sequence in "employer" [ɔɪ̯.ə])

As [eɪ̯] and [əʊ̯] become [ɛə̯] and [ɔː] respectively before /r/, most instances of [eɪ̯.ə] and [əʊ̯.ə] are words with the suffix "-er". Other instances are loanwords, such as boa.

[aʊ̯ə̯, aɪ̯ə̯, ɔɪ̯ə̯] are sometimes written with awə, ajə, ɔjə, or similarly. On Wikipedia, they are not considered to feature the approximants /w/ and /j/, following the analysis adopted by the majority of sources.

Second segment is the nucleus

Spanish:

The last two are mostly restricted to European Spanish. In Latin American Spanish (which has no distinct vosotros form), the corresponding words are cambian [ˈkambi̯an] and cambien [ˈkambi̯en] , with a rising-opening diphthong followed by a nasal stop and initial, rather than final stress. In phonology, [u̯ei̯, u̯ai̯, i̯ai̯, i̯ei̯] are analyzed as a monosyllabic sequence of three vowels: /uei, uai, iai, iei/. In Help:IPA/Spanish, those triphthongs are transcribed wej, waj, jaj, jej: [ˈbwej] , [uɾuˈɣwaj] , [kamˈbjajs] , [kamˈbjejs]

A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and stress.

A diphthong, also known as a gliding vowel, is a combination of two adjacent vowel sounds within the same syllable. Technically, a diphthong is a vowel with two different targets: that is, the tongue moves during the pronunciation of the vowel. In most varieties of English, the phrase no highway cowboy has five distinct diphthongs, one in every syllable.

Estuary English is an English accent associated with the area along the River Thames and its estuary, including London. Phonetician John C. Wells proposed a definition of Estuary English as "Standard English spoken with the accent of the southeast of England". Estuary English may be compared with Cockney, and there is some debate among linguists as to where Cockney speech ends and Estuary English begins.

The phonology of Portuguese varies among dialects, in extreme cases leading to some difficulties in intelligibility. This article focuses on the pronunciations that are generally regarded as standard. Since Portuguese is a pluricentric language, and differences between European Portuguese (EP), Brazilian Portuguese (BP) and Angolan Portuguese (AP) can be considerable, varieties are distinguished whenever necessary.

Trisyllabic laxing, or trisyllabic shortening, is any of three processes in English in which tense vowels become lax if they are followed by two or more syllables, at least the first of which is unstressed:

  1. The earliest occurrence of trisyllabic laxing occurred in late Old English and caused stressed long vowels to become shortened before clusters of two consonants when two or more syllables followed.
  2. Later in Middle English, the process was expanded to all vowels when two or more syllables followed.
  3. The Middle English sound change remained in the language and is still a mostly-productive process in Modern English, detailed in Chomsky and Halle's The Sound Pattern of English.

In linguistics, vowel length is the perceived length of a vowel sound: the corresponding physical measurement is duration. In some languages vowel length is an important phonemic factor, meaning vowel length can change the meaning of the word, for example in: Arabic, Finnish, Fijian, Kannada, Japanese, Latin, Old English, Scottish Gaelic, and Vietnamese. While vowel length alone does not change word meaning in most dialects of English, it is said to do so in a few dialects, such as Australian English, Lunenburg English, New Zealand English, and South African English. It also plays a lesser phonetic role in Cantonese, unlike in other varieties of Chinese.

The sound system of Norwegian resembles that of Swedish. There is considerable variation among the dialects, and all pronunciations are considered by official policy to be equally correct - there is no official spoken standard, although it can be said that Eastern Norwegian Bokmål speech has an unofficial spoken standard, called Urban East Norwegian or Standard East Norwegian, loosely based on the speech of the literate classes of the Oslo area. This variant is the most common one taught to foreign students.

This article is about the phonology of Bernese German. It deals with current phonology and phonetics, including geographical variants. Like other High Alemannic varieties, it has a two-way contrast in plosives and fricatives that is not based on voicing, but on length. The absence of voice in plosives and fricatives is typical for all High German varieties, but many of them have no two-way contrast due to general lenition.

L-vocalization, in linguistics, is a process by which a lateral approximant sound such as, or, perhaps more often, velarized, is replaced by a vowel or a semivowel.

The phonological system of the Hawaiian language is based on documentation from those who developed the Hawaiian alphabet during the 1820s as well as scholarly research conducted by lexicographers and linguists from 1949 to present.

English diphthongs have undergone many changes since the Old and Middle English periods. The sound changes discussed here involved at least one phoneme which historically was a diphthong.

Unlike many languages, Icelandic has only very minor dialectal differences in sounds. The language has both monophthongs and diphthongs, and many consonants can be voiced or unvoiced.

Monophthongization is a sound change by which a diphthong becomes a monophthong, a type of vowel shift. In languages that have undergone monophthongization, digraphs that formerly represented diphthongs now represent monophthongs. The opposite of monophthongization is vowel breaking.

Most languages of the world allow syllables without consonants, and monosyllabic words may therefore consist of a single vowel. Examples in English are a, O, I, eye. A smaller number of languages allow sequences of such syllables, and thus may have polysyllabic words without consonants. This list excludes monosyllables and words such as English whoa and yeah which contain the semivowels y and w.

Classical Armenian orthography, traditional orthography or Mashtotsian orthography, is the orthography that was developed by Mesrop Mashtots in the 5th century for writing Armenian and reformed during the early 19th century. Today, it is used primarily by the Armenian diaspora, including all Western Armenian speakers and Eastern Armenian speakers in Iran, which has rejected the Armenian orthography reform of Soviet Armenia during the 1920s. In the Armenian diaspora, some linguists and politicians allege political motives behind the reform of the Armenian alphabet.

Port Talbot English (PTE) is a variety of Welsh English spoken in Port Talbot, generally by the working class.

Getelands

Getelands or West Getelands is a South Brabantian dialect spoken in the eastern part of Flemish Brabant as well as the western part of Limburg in Belgium. It is a transitional dialect between South Brabantian and West Limburgish.
