• Source: Voiced alveolar and postalveolar approximants

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 equivalent X-SAMPA symbol is r\.
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. For further ease of typesetting, English phonemic transcriptions might use the symbol ⟨r⟩ even though this symbol represents the alveolar trill in phonetic transcription.
The bunched or molar r sounds remarkably similar to the postalveolar approximant and can be described as a voiced labial pre-velar approximant with tongue-tip retraction. It can be transcribed in IPA as ⟨ψ⟩ or ⟨ɹ̈⟩.




Features



Features of the voiced 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.
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.
