|
Larynx
|
Contains the vocal folds and the glottis
|
|
|
Vocal Folds
|
These are within the larynx. They are folds of muscle in the larynx. They open (voiceless) and close (voice).
|
|
|
Glottis
|
The space between the vocal folds
|
|
|
Alveolar ridge
|
Bony structure located just behind the front teeth
|
|
|
Hard palate
|
The hard palate is a thin horizontal bony plate of the skull, located in the roof of the mouth.
|
|
|
Velum
|
Soft part of the roof of the mouth behind the hard palate; when this part is raised the nasal cavity is closed; when it is lowered, air escapes from the nose and a nasal sound is produced
|
|
|
Nasal cavity
|
The nasal cavity is a large air-filled space above and behind the nose in the middle of the face.
|
|
|
Bilabial
|
Both lips
|
|
|
Labiodental
|
Lips and teeth
|
|
|
Interdental
|
Refers to sounds produced by positioning the tip of the tongue between the upper and lower teeth.
|
|
|
Alveolar
|
Description of sounds produced by making contact between the tongue and the alveolar ridge
|
|
|
Palatal
|
Refers to sounds made with the tongue approximating the hard part of the roof of the mouth
|
|
|
Velar
|
Sounds produced when the back of the tongue is raised toward the velum as the place of articulation.
|
|
|
Glottal
|
Sounds that are produced at the glottis
|
|
|
Stop
|
Made by obstructing the air stream completely in the oral cavity
|
|
|
Fricative
|
Are made by forming a nearly complete obstruction of the vocal tract
|
|
|
Affricate
|
Made by:
1. briefly stopping the air stream completely, and 2. releasing the articulators slightly so that frication is produced |
|
|
Nasal
|
Are produced by:
1. lowering the velum, and 2. (thus) opening the nasal passage to the vocal tract |
|
|
Liquid
|
Involve a substantial constriction of the vocal tract, but the constrictions for liquids are not narrow enough to block the vocal tract or cause turbulence
|
|
|
Glide
|
Made with only a slight closure of the articulators, (if the vocal tract were any more open, the result would be a vowel sound)
|
