A
voiceless palatal implosive
is a rare
consonantal
sound, used in some
spoken
languages
. The symbol in the
International Phonetic Alphabet
that represents this sound is ⟨
??
⟩ or ⟨
c?↓
⟩. A dedicated IPA letter, ⟨
?
⟩, was withdrawn in 1993.
Features
[

Features of the voiceless palatal 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
place of articulation
is
palatal
, which means it is articulated with the middle or back part of the
tongue
raised to the
hard palate
.
- 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.
