The alveolar approximant is a consonant. It is used in some languages. It is used in English where the letter "r" is used for the sound, as in run or brick. The International Phonetic Alphabet represents the alveolar and postalveolar approximants as ⟨ɹ⟩. International Phonetic Alphabet represents it as a lowercase letter r rotated 180 degrees, or in broad transcription ⟨r⟩; the X-SAMPA symbol of this is ⟨r\⟩.

Many times the symbol is written as ⟨r⟩ instead of ⟨ɹ⟩ because typing ⟨r⟩ is easier.

Features

  • The airstream mechanism is pulmonic. This means that this sound is produced by pushing air solely with the lungs and diaphragm, as in most sounds.
  • The phonation is voiced. This means that the vocal cords vibrate while the sound is being pronounced.
  • The place of articulation (where the sound is produced) is alveolar. This means that this sound is produced with the tip of the tongue (apical) or the blade of the tongue at the alveolar ridge (laminal).
  • The manner of articulation (how the sound is produced) is approximant. This means that this sound is produced by narrowing the vocal tract at the place this sound is produced. However, it is not narrowed enough to produce a turbulent airstream.
