Pronunciations of Paula I’ve heard (sorry, I don’t have an IPA font):
My mom (and other mid-Atlantic types): Pualuh or Pualeh. When you get into New York the oo sound can get even stronger, and the a weaker.
Mid_western US (what sounds like ‘no accent’ to most Americans: Pawluh
Texas and Southern: Pa-awluh
Speakers of Romance languages: Pow-lah or Pa-o-lah
Dutch speakers: Poe-luh
Mandarin speakers: Po-lah, with a less rounded o than the Dutch.
