The voiced 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 most common sound represented by the letter r in English is the voiced postalveolar approximant, pronounced a little more back and transcribed more precisely in IPA as ⟨ɹ̠⟩, but ⟨ɹ⟩ is often used for convenience in its place.
Features of the voiced alveolar approximant: As an allophone of other rhotic sounds, [ɹ] occurs in Edo, Fula, Murrinh-patha, and Palauan.
Shaded areas denote articulations judged impossible.
