As co-articulation ( Latin coarticulare , articulate together ' ), the influence of a sound by the phonetic context refers.

In phonetics , co- articulation is the term used for parallel, anticipatory (anticipatory) movements in articulation . This anticipation happens because the articulators (e.g. tongue or lips) move into the position of the following sound while a sound is being formed.

For example, a k -sound followed by an i -sound (front, unrounded vowel) sounds different than a k -sound followed by a u -sound (rear, rounded vowel). Due to learning processes , we can no longer distinguish some phoneme variants , which are physically quite different depending on the coarticulation .

Coarticulation can also lead to a fixed change in sound . For example, the German prefix ent- with the following f has changed in some cases due to a regressive contact assimilation to emp- (such as in to receive, to feel, ... ).
