I noticed you mentioned Ashkhanzi and Sefardi; are there different types of Hebrew? Different dialects as there are in other languages, like Chinese has Mandarin, Cantonese, Han and so on? I'm interested in learning it because I just started with a transcription company that is run by people who are Orthodox and they all speak Hebrew. They do speak English as well, but still, I would like to learn and it would be nice to learn the right one.
