Voiced dental, alveolar and postalveolar trills

"r (IPA)" redirects here. For the English r sound often transcribed /r/ for convenience, see Postalveolar approximant. For other r-like consonants, see Rhotic consonant.

The voiced 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 many Indo-European languages, a trill may often be reduced to a single vibration in unstressed positions. In Italian, a simple trill typically displays only one or two vibrations, while a geminate trill will have three or more.^[1] Languages where trills always have multiple vibrations include Albanian, Spanish, Cypriot Greek, and a number of Armenian and Portuguese dialects.^{[citation needed]}

People with ankyloglossia may find it exceptionally difficult to articulate the sound because of the limited mobility of their tongues.^[2][3]

Features

Features of the voiced alveolar trill:

• Its manner of articulation is trill, which means it is produced by directing air over an articulator so that it vibrates.
• Its place of articulation may be

dental (behind the upper front teeth),

alveolar (at the alveolar ridge), or

post-alveolar (behind the alveolar ridge).

• It is most often apical, which means it is pronounced with the tip of the tongue.^[4]
• Its phonation is voiced, which means the vocal cords vibrate during the articulation.
• It is an oral consonant, which means air is allowed to escape through the mouth only.
• It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.

Occurrence

A trill extended for about 2 seconds, captured in slow motion to reveal the individual 36–44 Hz tongue oscillations.

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 some speakers tend to pronounce it as [rʐ], [ɾʒ], or [ɹʒ]. In the IPA, it is typically written as ⟨r⟩ plus the raising diacritic, ⟨r̝⟩, but it has also been written as laminal ⟨r̻⟩.^[43] (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

Features of the voiced alveolar fricative trill:

• Its manner of articulation is fricative trill, which means it is a non-sibilant fricative and a trill pronounced simultaneously.
• Its place of articulation is laminal alveolar, which means it is articulated with the blade of the tongue at the alveolar ridge.
• Its phonation is voiced, which means the vocal cords vibrate during the articulation.
• It is an oral consonant, which means air is allowed to escape through the mouth only.
• It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.

Examples

Language		Word	IPA	Meaning	Notes
Czech[44][45][46][47]		čtyři	[ˈt͡ʃtɪr̝ɪ]ⓘ	'four'	May be a non-sibilant fricative.[45] It contrasts with /r/ and /ʒ/. See Czech phonology
Dzongkha[48]		རུ་ཏོག་/ru-tog	[r̝uto]	'bone'	Usually released as a normal trilled [r], sometimes it has a slightly fricative character vaguely reminiscent of Czech ř. Dzongkha r is followed by the low register tone.
Kashubian[49]		rzéka	[r̝eka]	'river'	Only some northern and northwestern speakers. Formerly common over the whole speaking area.[49]
Kobon		[example needed]			Amount of frication variable. May also be a fricative flap[citation needed]
Ormuri	Standard (Kaniguram)	تڒګب/tařgab	[tɑr̝geb]	'summer'	Corresponds to /ʃ/ in Logar dialect.
Polish	Some dialects[50]	rzeka	[r̝ɛka]	'river'	Contrasts with /r/ and /ʐ/.

Portuguese[51]	European	os rins	[u ˈr̝ĩʃ]	'the kidneys'	Possible realization of the sequence /sr/ for speakers who realize /r/ as [r].[51] See Portuguese phonology
Silesian	Gmina Istebna[52]	umrził	[ˈumr̝iw]	'(he) died'	Contrasts with /r/ and /ʒ/. Merges with /ʐ/ in most Polish dialects.
	Jablunkov[52]	[example needed]
Slovak	Northern dialects[50][53]	řyka	[ˈr̝ɪkä]	'river'	Only in a few dialects near the Polish border.[50] See Slovak phonology
Spanish		rana	[ˈr̝änä]	'frog'	Possible realization of /r/ in some dialects, may also be realized as a non-sibilant alveolar fricative [ɹ̝-] or as a sibilant retroflex fricative [ʐ].
Chicahuaxtla Trique[54]		raꞌa	[rᶾa˧ʔaː˧] or [r̥ᶴa˧ʔaː˧]	'hand'	Initial allophone of /r/.
Tsakonian[55]		ρζινοδίτζη	[r̝inoðitɕi]	'justice of the peace'	/ʒ/ appears to have been a fricative trill in the 19th century, and [ʒ] survived latterly only in women's usage in Southern Tsakonian.
