Here's why:
* Schwa sound: The schwa sound is a very short, unstressed vowel sound represented by the symbol /ə/. It's often described as a "uh" sound.
* Admiration: The stressed vowel sound in "admiration" is the "a" in "ad". The other vowel sounds are not unstressed and don't have the schwa sound.
The word "admiration" is pronounced with a clear "a" sound in "ad" and a long "i" sound in "mir".
