Airstream mechanisms
Phonetics midterm
| Question | Answer |
|---|---|
| Airstream Mechanisms | In order for there to be sound there must be moving air -For speech, something must set the air in motion (airstream mechanism) |
| Pulmonic Egressive Airstream mechanism | Air moving outward initiated by the lungs |
| Non-pulmonic airstreams | -Glottalic Egressive Airstream -Glottalic Ingressive Airstream -Velaric ingressive Airstream |
| Glottalic Egressive Airstream (ejectives) | - Larynx is raised, glottis is closed -Air pressure in the vocal tract increases --> when the air is released, a popping sound is produced |
| Glottaic Ingressive Airstream (implosives) | -Larynx is lowered - Air pressure is lowered -Causing air to rush in |
| Velaric Ingressive Airstream (clicks) | Produced with air trapped between a closure at the velum (soft palate) and another anterior closure like the alveolar ridge |
| Phonation types | -voicing -breathy -creaky |
| Breathy (murmur) | Vocal folds vibrate while remaining apart |
| Creaky (vocal fry) | produced with the posterior part of the vocal folds held tightly together while the anterior par tis vibrating at a slow rate |
| Diacritics | broad vs. narrow transcription |
| Broad Transcription (phonemic transcription) | Ignores details, capturing only enough of a pronunciation to show how tha word differs from other words in the language |
| Narrow transcription | Captures as much of the specific pronunciation as possible with as many details as possible |
