I have a particular question in mind, which may be somewhat opinion-based and thus off-topic here. My question is on the pronuncation of "Catholicism". I've heard it pronounced by emphasizing on the first syllable, even though online pronunciation guides say it's pronounced on the second syllable. Now, you may think "Well, it must be idiosyncratic then!" No, I don't think it's that person's idiosyncrasy, because this artist tends to pronounce that way too. I believe, for this reason, that the unusual pronunciation is really a dialect, and I need help in identifying this dialect.
Dialect questions are a bit haphazard, but we have answered them before. If you post your two examples and possibly more, and feel you can identify other common dialectal features, you have a good shot of being on topic. However, it's difficult to identify a dialect from a single word. Maybe you could compare the backgrounds of those two people and discover a common dialect and have your answer that way.
