Ejective sounds are made using the ejective airstream mechanism. For example, an ejective [t'] is made by:
- making an alveolar closure and closing the vocal folds. (This traps air between the two closures.)
- raising the larynx in the throat. (Since the larynx houses the vocal folds, which are still closed, this causes the trapped air to occupy less volume and raises its pressure.)
- releasing the alveolar closure. (The pressurized air rushes out much more forcefully than in a normal [t].)
- finally opening the vocal folds again.
Because the vocal folds are closed until the end of the sound, ejectives are always voiceless. (For similar reasons, ejectives can never be nasal.)
