The linguolabial ejective is a type of consonantal sound used in disordered speech.[1] The symbol in the International Phonetic Alphabet that represents this sound is ⟨t̼ʼ⟩ or ⟨p̺ʼ⟩.
Features
Features of the linguolabial ejective:
- 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 linguolabial, which means it is articulated with the tongue against the upper lip.
- 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 ejective (glottalic egressive), which means the air is forced out by pumping the glottis upward.
