Dental, alveolar and postalveolar trills

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

The alveolar trill is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents dental, alveolar, and postalveolar trills is ⟨r⟩, and the equivalent X-SAMPA symbol is r. It is commonly called the rolled R, rolling R, or trilled R. Quite often, ⟨r⟩ is used in phonemic transcriptions (especially those found in dictionaries) of languages like English and German that have rhotic consonants that are not an alveolar trill. That is partly for ease of typesetting and partly because ⟨r⟩ is the letter used in the orthographies of such languages.

In most Indo-European languages, the sound is at least occasionally allophonic with an alveolar tap [ɾ], particularly in unstressed positions. Exceptions include Albanian, Spanish, Cypriot Greek, and a number of Armenian and Portuguese dialects, which treat them as distinct phonemes. In a few languages, such as Batsbi, the tap is the vastly preferred allophone, to such a degree that it is treated as a phoneme whilst the trill is not.[citation needed]

People with ankyloglossia may find it exceptionally difficult to articulate the sound because of the limited mobility of their tongues.[1][2]

Most commonly, the alveolar trill is voiced.


Features of the alveolar trill:


A trill extended for about 2 seconds by a non-native user, captured in slow motion to reveal the individual 36~44Hz tongue oscillations.

Voiced alveolar fricative trill [edit]

In Czech, there are two contrasting alveolar trills. Besides the typical apical trill, written r, there is another, laminal trill, written ř, in words such as rybáři [ˈrɪbaːr̝ɪ] 'fishermen' and the common surname Dvořák. Its manner of articulation is similar to [r] but is laminal and the body of the tongue is raised. It is thus partially fricative, with the frication sounding rather like [ʒ] but less retracted. It sounds like a simultaneous [r] and [ʒ], and non-native speakers may pronounce it as [rʐ] or [ɹʒ]. In the IPA, it is typically written as ⟨r⟩ plus the raising diacritic, ⟨⟩, but it has also been written as laminal ⟨⟩.[33] (Before the 1989 IPA Kiel Convention, it had a dedicated symbol ⟨ɼ⟩.) The Kobon language of Papua New Guinea also has a fricative trill, but the degree of frication is variable.


Features of the voiced alveolar fricative trill:


Language Word IPA Meaning Notes
Czech[34][35][36][37] čtyři About this sound[ˈt͡ʃtɪr̝ɪ]  'four' May be a non-sibilant fricative.[35] It contrasts with /r/ and /ʒ/. See Czech phonology
Kashubian[38] [example needed] Only some northern and northwestern speakers.[38]
Kobon [example needed] Amount of frication variable. May also be a fricative flap[citation needed]
Polish Some dialects[39] rzeka 'river' Contrasts with /r/ and /ʐ/. Present in areas from Starogard Gdański to Malbork[39] and those south, west and northwest of them,[39] area from Lubawa to Olsztyn to Olecko to Działdowo,[39] south and east from Wieleń,[39] around Wołomin,[39] southeast from Ostrów Mazowiecka[39] and west from Siedlce,[39] from Brzeg to Opole and those north of them,[39] and roughly from Racibórz to Nowy Targ.[39] Most speakers, as well as standard Polish merge it with /ʐ/,[39] and speakers maintaining the distinction (which is mostly the elderly) sporadically do that too.[39] See Polish phonology
Portuguese[40] os rins [u ˈr̝ĩʃ] 'the kidneys' Possible realization of the sequence /sr/ for speakers who realize /r/ as [r].[40] See Portuguese phonology
Silesian Gmina Istebna[41] umrz [ˈumr̝iw] '(he) died' Contrasts with /r/ and /ʒ/. Merges with /ʐ/ in most Polish dialects.
Jablunkov[41] [example needed]
