The voiceless retroflex plosive or stop is a type of consonantal sound, used in some spokenlanguages. This consonant is found as a phoneme mostly (though not exclusively) in two areas: South Asia and Australia.
Transcription
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 "t" (the letter used for the equivalent alveolar consonant). In many fonts lowercase "t" already has a rightward-pointing hook, but ⟨ʈ⟩ is distinguished from ⟨t⟩ by extending the hook below the baseline.
Features
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 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.
