pronounced as [ɨ] (close central unrounded vowel),

Note the vowel chart halfway down the right side of the page.

Takes a lot of practice to be able to feel the vowels in your mouth as the chart describes; when I first started learning the chart, I felt like it was inverted from what my mouth felt, but it is indeed, correct.
