Here's why:
* Schwa sound: The schwa sound (ə) is a very short, unstressed vowel sound. It's often found in unstressed syllables.
* "Alone" pronunciation: The word "alone" is pronounced with a long "o" sound (əˈloʊn). The "a" is stressed, and there's no unstressed syllable at the end.
Therefore, there's no schwa sound in the word "alone".
