同化：d 碰到 you

In fluent speech, when one word ends in a /d/ sound and the next begins in a /j/ sound, the two sounds come together and change to a /dʒ/ sound. The vowel in 'you' can also change to schwa.

Tim 在视频里出了个谜：一块木头（wood）加一头母羊（ewe，读音同 you），合起来是什么？wood + ewe = would you。d 和 /j/ 碰在一起，舌头来不及分开发，就合成了 /dʒ/。

you 本身也常弱读成 /jə/，所以 would you 最终听上去是 wouldja /wʊdʒə/。did you、had you、need you 都一样。
