These two sounds are similar, but Vowel ee /i/ has a more exaggerated smile posture for the lips, and the front of the tongue is slightly higher in the mouth. Vowel ee /i/ is a tense vowel, meaning that the muscles in the face are engaged. Vowel I /ɪ/ is a lax vowel, meaning the lips and face need to be relaxed.
