| Topic-092: Glottalic Airstream Mechanism This mechanism involves glottis as the adjective could be used to refer to anything pertaining to the glottis. A glottalic airstream is produced by making a tight closure of the vocal folds and then moving the larynx up or down thus raising of the larynx pushes the air outwards causing an egressive glottalic airstream. Similarly, while lowering, the larynx pulls air into the vocal tract and it is called an ingressive glottalic airstream. Sounds of this type found inhuman language are called ejective or implosive Copyright Virtual University of Pakistan Phonetics and Phonology (ENG) VU respectively. Glottalization as a process is used for any articulation involving a simultaneous glottal constriction (e.g., a glottal stop. In English, glottal stops are often used in this way to reinforce a voiceless plosive at the end of a word as in what. Such sounds, made while the glottis is closed, are produced without the direct involvement of air from the lungs. Air is compressed in the mouth or pharynx above the glottal closure, and released while the breath is still held thus the resultant sounds produced in this glottalic airstream mechanism are known as ejective sounds. They are also called ‘glottalic’ or glottalized sounds (though the latter term is often restricted to sounds where the glottal feature is a secondary articulation. In languages like Quechua and Hausa ejective consonants are used as phonemes. A further category of sounds involving a glottalic airstream mechanism is known as implosive. Download 1.01 Mb.
