Voiceless alveolar and postalveolar approximants

The voiceless 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 voiceless approximants is ⟨ɹ̥⟩, and the equivalent X-SAMPA symbol is r\_0.

Features

Features of the voiceless 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 voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.

• 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.
