Articulation
The motion or positioning of some part of the vocal tract with respect to some other vocal tract surface in the production of a speech sound
-
Pulmonic Egressive Airstream
Airstream mechanism used in english. Literally blowing out action that uses lung(s)
-
Larynx
Contains vocal folds and glosttis
-
Vocal Tract
Above the larynx, composed of the oral and nasal cavities
-
Subglottal System
located below the larynx
-
Glottis
Opening between the vocal folds
-
Voiced Sounds
Sounds made with the vocal folds vibrating
-
Voiceless Sounds
Vocal Folds do not vibrate
-
Bilabial Consonant
Both lips touch to make sound Ex: [p] [b]
-
Labiodental Consonant
Lower lip touches upper front teeth to make sound Ex: [f] [v]
-
Interdentals
Made with the tip of the tongue protruding between the front teeth Ex: [O], [�] (thigh, thy)
-
Alveolar sounds
made with the tongue tip at or near alveolar ridge Ex: [t] [d] [s] [z] [l] [?]
-
Palatal sounds
Tongue against back (Farther back than alveolar ridge) Ex: [?] [?] [??] [??] [j]
-
Velar Consonants
Tongue touches farther back than Palate [k] [g] [?]
-
Glottal Sounds
produced at the larynx. [h] [?]
-
Manner of articulation
How the airstream is modified by the vocal tract to produce the sound
-
Stops
Airstream completely obstructed
-
Fricatives
Airstream nearly completely obstructed
-
Affricates
Briefly stopping the airstream completely then releasing the articulators slightly. I.e. stop+fricative
-
Nasals
Lowering the velum and opening the nasal passage to the vocal tract
-
Liquids
Vocal tract constricted, but not enough to cause turbulance
-
Glides
only slight closure of the articulators, so that if the vocal tract were any more open, the result would be a vowel sound.
