A voiceless alveolar implosive is a rare
consonantal sound, used in some
spokenlanguages. The symbol in the
International Phonetic Alphabet that represents this sound is ⟨ɗ̥ ⟩ or ⟨tʼ↓⟩. A dedicated IPA letter, ⟨ƭ⟩, was withdrawn in 1993.
Features
Features of the voiceless alveolar implosive:
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.
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
implosive (glottalic ingressive), which means it is produced by pulling air in by pumping the
glottis downward. As it is voiceless, the glottis is completely closed, and there is no pulmonic airstream at all.
