音标与实际发音不符@naked -ed？

吴二

naked中ed发音。美式发音，到底是 id 还是 əd？

Macmillan注的很清楚，
; {6 P6 ^' V/ a. J3 }0 K+ Y0 U& y英式：
% q! g+ o( c  k5 P, ~+ r, B% I# ?
美式：
  r+ Q1 @8 w1 `2 J, z% X" p9 l4 b
. i  [" e" A5 r8 H/ J
所以，
, j: b1 _$ q  k6 Z& `$ X3 [6 DMW:
" Q% O! }9 ?: v8 G6 J1 r$ `

AHD的表音符号比较特殊：

0 S, C+ d4 z' P" u& |0 G1 d5 ~

但恕我耳浊，听读音听不出来什么差异，感觉都是id。
. x. M( C6 E3 X# f5 c" }/ p! E
然后有意思的来了，朗文的-ed读音，标注如下，但朗读和标注并不一致：

- Y% ~: X8 y2 V& i7 P
4 @. \& B/ z  F不知道大家怎么看，美式的əd和英式的id有多大差别呢？

The current IPA key used in the English Wikipedia writes this reduced vowel that can be either [ɪ] or [ə] in shorthand as /ᵻ/ following the Oxford English Dictionary (e.g. needed /ˈniːdᵻd/, rested /ˈrɛstᵻd/).
* t2 |) K/ S7 g# M0 `/ O...
% H1 U& d* K9 [" [& NThere are some words where you would use /ᵻd/ for -ed even after consonants that are not /d/ or /t/, especially adjectives such as rugged /ˈrʌɡᵻd/ or naked /ˈneɪkᵻd/. In American English, [ə] tends to be higher and more like [ɪ] when it's next to /ɡ/ or /k/ (witness the eye-dialect spelling 'Linkin' for Lincoln), so in reality it would be difficult to decide if you're actually hearing [ˈrʌɡɪd] and [ˈneɪkɪd] or [ˈrʌɡəd] and [ˈneɪkəd] for these examples.
