 另外，这个音实际上还有第 3 个版本，<span class="pho">ɪ</span> 在词汇末尾的时候，更倾向于像是 <span class="pho">iː</span> 这个长元音的更短版本，<span class="pho">i</span>，长度介于 <span class="pho">ɪ</span> 和 <span class="pho">iː</span> 之间 —— 也就是说，<span class="pho">i</span> 是个半长元音。比如，*responsibility* <span class="pho alt">rɪˌspɑːn·səˈbɪl·ə·t̬i</span><span class="speak-word-inline" data-audio-us-male="/audios/us/responsibility-us-male.mp3" data-audio-us-female="/audios/us/responsibility-us-female.mp3"></span>.
 
-In addition, this sound actually has a third variation. When <span class="pho">ɪ</span> appears at the end of words, it tends to sound more like a shortened version of the long vowel <span class="pho">iː</span> — <span class="pho">i</span>, with a length somewhere in between <span class="pho">ɪ</span> and <span class="pho">iː</span>, which means <span class="pho">i</span> is a *semi-long vowel*. For instance, in the word *responsibility <span class="pho alt">rɪˌspɑːn·səˈbɪl·ə·t̬i</span><span class="speak-word-inline" data-audio-us-male="/audios/us/responsibility-us-male.mp3" data-audio-us-female="/audios/us/responsibility-us-female.mp3"></span>.
