Voiceless retroflex plosive
This article needs additional citations for verification. (January 2018)
The voiceless retroflex plosive or stop is a type of consonantal sound, used in some spoken languages. This consonant is found as a phoneme mostly (though not exclusively) in two areas: South Asia and Australia.
|Voiceless retroflex plosive|
The symbol that represents this sound in the International Phonetic Alphabet is ⟨ʈ⟩. Like all the retroflex consonants, the IPA symbol is formed by adding a rightward-pointing hook extending from the bottom of tee (the letter used for the equivalent alveolar consonant). In many fonts lowercase tee already has a rightward-pointing hook, but ⟨ʈ⟩ is distinguished from ⟨t⟩ by extending the hook below the baseline.
Features of the voiceless retroflex stop:
- Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive.
- Its place of articulation is retroflex, which prototypically means it is articulated subapical (with the tip of the tongue curled up), but more generally, it means that it is postalveolar without being palatalized. That is, besides the prototypical subapical articulation, the tongue contact can be apical (pointed) or laminal (flat).
- 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.
