|
Describe the difference between voiced and voiceless sounds.
|
When voiced, the vocal folds at the larynx are closed so that it will vibrate as air pass through.
|
|
|
Describe bilabial articulation.
|
The lips move close together
|
|
|
Describe labiodental articulation.
|
The lower lips are pressed against the upper front teeth.
|
|
|
Describe interdental articulation.
|
The tip of the tongue is in between the teeth.
|
|
|
Describe alveolar articulation.
|
The tongue tip is at or near the alveolar ridge.
|
|
|
Describe post-aveolar articulation.
|
The tongue tip is at the front of the hard palate and behind the aveolar ridge.
|
|
|
Describe palatal articulation.
|
The tongue tip is at the center of the hard palate.
|
|
|
Describe velar articulation.
|
Tongue tip is at roof of mouth behind the hard palate at the velum.
|
|
|
Describe glottal articulation.
|
The sound is made at the space between the vocal folds and the glottis (the larynx)
|
|
|
Describe stops.
|
The air stream is *completely* obstructed in the *oral* cavity.
|
|
|
Describe Fricatives
|
The air stream is *mostly* obstructed so that a turbulent noise is produced (hissing i.e. frication)
|
|
|
Describe Affricates
|
Stopping the air stream completely so that frication is produced.
|
|
|
Describe Nasals
|
The velum is lowered so that air flows through the nasal passage.
|
|
|
Describe Liquids
|
There is a *constriction* that is not narrow enough to cause turbulence.
|
|
|
Lateral vs Retroflex liquids
|
Retroflex involves curling of the tip of the tongue at the back of aveolar ridge.
|
|
|
Flaps vs stops
|
Flaps are quicker.
|
|
|
Glides
|
Slightly more constriction than a vowel.
|
|
|
Articulatory vs Auditory, vs Acoustic
|
Bilogical, Psychological, Physicalc
|
|
|
Vowels vs Consonants
|
Syllabicity: More likely to form nucleus of syllable.
Acoustic: longer and louder Ariticulation: no constriction |
