Sound

The alveolar approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents the alveolar and postalveolar approximants is ɹ, a lowercase letter r rotated 180 degrees. The equivalent X-SAMPA symbol is r\.

For ease of typesetting, English phonemic transcriptions might use the symbol r instead of ɹ, even though the former symbol represents the alveolar trill in phonetic transcription.

Features[edit]

Features of the alveolar approximant:

  • Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream.
  • Its place of articulation is alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal.
  • Its phonation is voiced, which means the vocal cords vibrate during the articulation. However, in some languages (like Swiss German) it can just mean that this consonant is pronounced shorter and weaker than its voiceless counterpart, while its voicedness or lack thereof is not relevant. In such cases it's more accurate to call such sounds lenis or lax.
  • 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.
  • The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.

May also be a labialized retroflex approximant; corresponds to an [r] or [ɾ] in a few other dialects. For convenience it is often transcribed r. See English phonology
