语言学中的coarticulation协同发音指什么？

Question

最好能举例说明一下

Answer 1

Coarticulation in phonetics refers to two different phenomena:

the assimilation of the place of articulation of one speech sound to that of an adjacent speech sound. For example, while the sound /n/ of English normally has an alveolar place of articulation, in the word tenth it is pronounced with a dental place of articulation because the following sound, /θ/, is dental.
the production of a coarticulated consonant, that is, a consonant with two simultaneous places of articulation. An example of such a sound is the voiceless labial-velar plosive /k͡p/ found in many West African languages.
Coarticulation may also refer to the transition from one gesture to another.

“协同发音”，摘自《语言学教程》（主编：胡壮麟.副主编：姜望琪北京大学出版社）话语是一个连续的过程，所以发音器官不是从一系列分离的步骤中从一个音段移到下一个音段。实际情况是，语音会持续地收到它们临近音的影响。当涉及到这种同时或重合的发音时，我们称这些过程为协同发音。如果语音改变，接近于后面的音，它就被称为逆化协同发音，如果发音显示出前面语音的影响，它就是重复性协同发音，逆化协同发音比重复性协同发音更为常见。
