In phonetics, an r-colored or rhotic vowel (also called a retroflex vowel, vocalic r, or a rhotacized vowel) is a vowel that is modified in a way that results in a lowering in frequency of the third formant. R-colored vowels can be articulated in various ways: the tip or blade of the tongue may be turned up during at least part of the articulation of the vowel (a retroflex articulation) or the back of the tongue may be bunched. In addition, the vocal tract may often be constricted in the region of the epiglottis.

R-colored vowels are exceedingly rare, occurring in less than one percent of all languages. However, they occur in two of the most widely spoken languages: North American English and Mandarin Chinese. In North American English, they are found in words such as ''dollar'', ''butter'', ''third'', ''color'', and ''nurse''. They also occur in Canadian French, some varieties of Portuguese, some Jutlandic dialects of Danish, as well as in a few indigenous languages of the Americas and of Asia, including Serrano and Yurok in the United States, Luobohe Miao in China, and Badaga in India.

Notation

In the IPA, an r-colored vowel is indicated by a hook diacritic placed to the right of the regular symbol for the vowel. For example, the IPA symbol for schwa is , while the IPA symbol for an r-colored schwa is . This diacritic is the hook of , a symbol constructed by John Samuel Kenyon along with by adding the retroflex hook (right hook) to and . Both and were proposed as IPA symbols by editors of the ''American Speech'' in 1939 to distinguish it from .

The IPA adopted several ways to transcribe r-colored vowels in its 1947 chart: the turned r ; the superscript turned r , , , , etc.; the retroflex hook , , , , etc.; and added as a variant of in its 1951 chart. In 1976 the retroflex hook was dropped due to insufficient usage. In 1989, at the Kiel Convention, the hook of and was adopted as a diacritic placed on the right side of the vowel symbol for r-colored vowels, e.g. . Following the convention of alternating and for non-rhotic accents, and signify stressed and unstressed, respectively, rather than a difference in phonetic quality. The use of the superscript turned r () is still commonly seen.

Examples

English

R-colored vowels are found in most rhotic forms of English, including General American and Irish English. The r-colored vowels of General American can be written with "vowel-r" digraphs:
*: ''hearse'', ''assert'', ''mirth'' (stressed, conventionally written ); ''standard'', ''dinner'', ''Lincolnshire'' (unstressed)
*: ''start'', ''car''
*: ''north'', ''war''

In words such as ''start'', many speakers have r-coloring only in the coda of the vowel, rather than as a simultaneous articulation modifying the whole duration. This can be represented in IPA by using a succession of two symbols such as or , rather than the unitary symbol .

Singing

In European classical singing, dropping or weakening of r-colored vowels has been nearly universal and is a standard part of classical vocal training. However, there have always been other singing styles in which r-colored vowels are given their full emphasis, including traditional Irish singing styles and those of many performers of country music. In certain particular cases, a vowel + /r/ is pronounced instead as two syllables: a non-rhotic vowel followed by a syllabic /r/.

Mandarin Chinese

In Mandarin, the rhotacized ending of some words is the prime way by which to distinguish speakers of Standard Northern Mandarin (Beijing Mandarin) and Southwestern Mandarin from those of other forms of Mandarin in China. Mandarin speakers call this phenomenon ''erhua''. In many words, the ''-r'' suffix () is added to indicate some meaning changes. If the word ends in a velar nasal (''ng''), the final consonant is lost and the vowel becomes nasalized. Major cities that have this form of rhotacized ending include Beijing, Tianjin, Tangshan, Shenyang, Changchun, Jilin, Harbin, and Qiqihar. This ''erhua'' has since spread to other provincial capitals not home to Standard Mandarin, such as Shijiazhuang, Jinan, Xian, Chongqing, and Chengdu.

In rhotic accents of Standard Mandarin, such as those from Beijing, Tianjin, most of the Hebei province (e.g. Tangshan, Baoding, Chengde), eastern Inner Mongolia (e.g. Chifeng, Hailar), and in the Northeast, vocalic r occurs as a diminutive marker of nouns () and the perfective aspect particle (). This also occurs in the middle syllables of compound words consisting of three or more syllables. For example, the name of the famous restaurant Go Believe () in Tianjin is pronounced as 'Gourbli' (''Gǒu(r)bùlǐ'' → ''Gǒurblǐ''). The name of the street Dazhalan () in Beijing is pronounced as 'Da-shi-lar' (''Dàshànlàn(r)'' → ''Dàshílàr'').

Quebec French

In Quebec French, the vowel is generally pronounced and the r-colored vowels are also pronounced in loan words. For example, the word ''hamburger'' can be pronounced , the word ''soccer'' can be pronounced etc.

Other examples

In the 1930s the Dravidian language Badaga had two degrees of rhoticity among all five of its vowels, but few speakers maintain the distinction today, and then only in one or two vowels. An example is non-rhotic "mouth", slightly rhotacized ("half retroflexed") "bangle", and fully rhotacized ("fully retroflexed") "crop".

The Algic language Yurok illustrated rhotic vowel harmony. The non-high vowels , and could become in a word that has . For example, the root 'three' became in the word 'three (animals or birds)'.

Luobohe Miao also contains .
