I am currently in an MA Linguistics program and I am looking into doing some research in Coptic. However, most scholarly sources are pre-IPA (International Phonetic Alphabet) and I am looking into the pronunciation differences. While I could eventually "translate" Maher's 1975 transcriptions, I don't currently have the time to do so - so I'm hoping someone has other information.
The only exception I can find is the article from 2004 by Michael Szelog but I haven't been able to find anything about this author and their scholarly background.
Does anyone have any other sources on either the Greco-Roman or the Old-Bolhairic pronunciation? Thank you!
