9.1 音的同化（Assimiliation）

issue 的音标是/ isju:/，但发音时却读成了/ iʃu:/。为什么会发生这种变音现象呢？原来/s/与/j/相遇，发声时舌位自然会上升，发/s/ 时，发音器官只作准备，马上让位于/j/和紧随而来的元音的发音，这样便发成既不是/s/也不是/j/ 的第三音。又如，education音标是/ edjuˈkeiʃn/，朗读时读成/ edʒu keiʃn/，这是因为/d/和/j/相遇时，气流突破阻碍流向舌前部与硬颚间，带着后面的元音发成/dʒu/。这种某个音因受了一个相邻音的影响而发成另一个音的情况就是音的同化。

9.2 连读（Liaison）

在两词相邻的词组，意群或句子中，前一个词的末尾是辅音，后一个词的开头是元音时，这一头一尾就可以连起来作为一个音节来读，这就是我们经常所说的连读。
