西单局气餐厅:协同发音

coarticulation /kǝʊɑ:tɪkju'leɪʃn/ n. 协同发音 ⒈（又double articulation ）指发音时在声道中的两个（或偶遇多个）不同的部位形成阻碍．这两个阻碍可能同样是完全阻塞（如协同发音的塞音[kp]）,或其中一个阻碍程度较轻（如圆唇化的软腭塞音[kW]）．Catford（1977）称前一种情形为‘等同协同发音’，后一种情形为‘非等同协同发音’．⒉ 见accommodation （义项1）．Adj. coarticulated．

accommodation /ǝkɒmǝˈdeɪʃn/ n. 同化 ⒈（又coarticulation）指前位音段为易于向后接音段的过渡而发生的（发音）变化，如在英语中当/k/位于前位元音或滑音之前（key, back yard）时的改变，或当/t/在齿擦音前面（如eighth）时由龈音变化为齿音. 见spreading. 又见allophone. ⒉ 指谈话者自觉或不自觉地将其口音趋同于（或分别于）对方或周围人群. 又见adaptation.

Speech is a continuous process, so the vocal organs do not move from one sound segment to the next in the series of separate steps. Therefore, sounds continually show the influence of their neighbours.
For example, if the unrounded vowel[i:] and the rounded vowel [u:] effect the [s] in (seat) and (soup) respectively. In the production of [s] in[si:t], the lips are unrounded, while [s] in [su:p] they are rouned.
So, when simultaneous or overlapping articulations are involved, we call the process COARTICULATION.
If the sound becomes more like the following sounds, as in above example, it is known as Anticipatory Corarticulation. If the sound displays the influence of the preceding sound, it is Perserverative Coarticulation.
