What is the initiator of the glottalic airstream mechanism?
What is the initiator of the glottalic airstream mechanism?
The organ generating the airstream is called the initiator and there are three initiators used in spoken human languages: the diaphragm together with the ribs and lungs (pulmonic mechanisms), the glottis (glottalic mechanisms), and….Percussive consonants.

What are pulmonic and glottalic sounds?
In human speech, egressive sounds are sounds in which the air stream is created by pushing air out through the mouth or nose. The three types of egressive sounds are pulmonic egressive (from the lungs), glottalic egressive (from the glottis), and lingual (velaric) egressive (from the tongue).
What is ingressive airstream mechanism?
Lingual ingressive, or velaric ingressive, describes an airstream mechanism in which a sound is produced by closing the vocal tract at two places of articulation in the mouth. This rarifies the air in the enclosed space by lowering the tongue and then releasing both closures. Such sounds are called “clicks”.
What is the initiator in the production of clicks?
The third form of initiation in human language is velaric or lingual initiation, where a sound is produced by a closure at two places of articulation, and the airstream is formed by movement of the body of the tongue. Velaric stops are more commonly known as clicks, and are almost universally ingressive.
What modifies the airstream when speech is produced?
The airstream (the source of sound production) is initiated by the lungs and respiratory airways. A constriction in the airways (glottal or supraglottal) modifies the flow.
What are glottalic sounds?
In phonetics, a glottalic consonant is a consonant produced with some important contribution (movement or closure) of the glottis. Glottalic sounds may involve motion of the larynx upward or downward, as the initiator of an egressive or ingressive glottalic airstream mechanism respectively.
What are implosives and ejectives?
Thus, clicks are velaric ingressive sounds, while implosives are glottalic ingressive sounds. Ejectives are glottalic egressive sounds – that is, the air flows out from the vocal tract. Therefore, ejectives share the direction of the air with pulmonic sounds, and share their airstream mechanism with implosives.
What are the 3 systems in vocal sound production?
The “spoken word” results from three components of voice production: voiced sound, resonance, and articulation.
What is glottalic airstream?
Glottalic airstream mechanism: The movement of pharynx air by the action of the glottis. An upward movement of the closed glottis will move the air out of the mouth; a downward movement of the closed glottis will cause air to be sucked into the mouth.
How is sound produced initiation?
In phonetics, initiation is the action by which an air-flow is created through the vocal tract. Along with articulation, it is one of the two mandatory aspects of sound production: without initiation, there is no sound. The means of initiating a phone is called its airstream mechanism.
