User:TimothyMills/Active articulator

In the production of a Consonant during speech, the active articulator is the anatomical structure that moves and the passive articulator is the one that does not move. For example, in the production of the sound (the first sound in English "tea"), the active articulator is the  tongue tip and the passive articulator is the alveolar ridge.

Active and passive articulators for different speech sounds
Cover main place categories from the IPA. Include reference to English words where possible.

1 See ambiguous cases below.

2 Not all English speakers use a retroflex "r".

Ambiguous cases
Not all consonants involve a clearly active and a clearly passive articulator. For example, in the production of labial sounds such as and, both lips move to form the constriction. In the production of glottal consonants such as, both vocal cords move.
