/i/ sound as in sit, if, evening, it:
1. Face is relaxed.
2. The front part of the tongue raises towards the roof of the mouth. It also, while it raises, spreads wide there in the front (with the sides in contact with the teeth laterally).
3. The tip of the tongue remains down, touching behind the bottom front teeth.
4. Pull back the corner of your mouth a little bit.
5. When the sound is in the beginning of a word, the tip of the tongue is drawing back more, no touching of the bottom front teeth at all; the sound comes from your lower chest; it’s a quick, bursting sound.
回答: 矫正发音随笔：短I的发音问题，高手绕行 由 ntotl 于 2009-12-04 21:24:06
很好地发现：短I起头时与短I在单词中间时，/I/的发音有区别。我的感觉是：短I在单词中间时，舌尖下压，舌尖并触及前部下牙；舌前部向上抬起；同时，舌平铺开，感觉到舌触及两侧牙齿。
短I起头时,舌尖下压，舌整体后撤，舌尖可完全不触及前部下牙；舌前部向上抬起；同时，舌平铺开，感觉到舌触及两侧上下牙齿。声音从胸腔发出。
/i:/和/i/的最大区别是/i:/舌整体不是平铺开，舌最多只触及两侧上面的牙齿。
你的录音表明，你已经很好的掌握了短I起头的音。只是保持的问题了。起码我的感觉是这样，不知高手们有何评论。
