The Different Pronouncations of Paleo According to My Family

I've been paleo for a month and eveytime I explain it to my family they always have a question to ask, but what confuses me is the way that they pronounce the actual word
  1. Grandma: poh-lay- oh
  2. Mom: poh-lee-oh
    No mom, I do not have a highly infectious viral disease
  3. Sister: pay-lee-oh
  4. Dad: pa-lee-oh
