2.1.6. ɪ/i/iː

ɪ 并不是长元音 iː 的更短版本，它更像是 e 和 i 之间的一个音。听起来很像是更短版本的 eɪ，从唇形上来看ɪ 更接近 e 。

The ɪ sound doesn't merely represent a shorter version of the long vowel iː. Instead, it seems to inhabit a space somewhere between e and i. It sounds more like a shorter rendition of eɪ, and visually speaking, the lip shape for ɪ is more akin to e.

另外，这个音实际上还有第 3 个版本，ɪ 在词汇末尾的时候，更倾向于像是 iː 这个长元音的更短版本，i，长度介于 ɪ 和 iː 之间 —— 也就是说，i 是个半长元音。比如，responsibility rɪˌspɑːn·səˈbɪl·ə·t̬i.

In addition, this sound actually has a third variation. When ɪ appears at the end of words, it tends to sound more like a shortened version of the long vowel iː — i, with a length somewhere in between ɪ and iː, which means i is a semi-long vowel. For instance, in the word *responsibility rɪˌspɑːn·səˈbɪl·ə·t̬i.
