Voiceless alveolar and postalveolar approximants
|Voiceless alveolar approximant|
|IPA Number||151 402A|
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
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.
