There are two accent patterns for two syllable words.
1. Accent on the first syllable:
The accent is usually on the first syllable in three-syllable words. The unaccented middle syllable has a schwa sound, the short u. This occurs in the words Jennifer, visitor, happily.
2. Accent on the second syllable:
When a word has a prefix and a suffix, then the accent is on the root-word. The root-word will be the second syllable. This occurs in the words distasteful, biweekly, reflection.
