Ah, friend,
The files I linked to were meant to serve as an example of what I was talking about. If you listened to one you don't need to know Greek to note that the narrator spoke clearly, not all that fast, and put feeling into the text. He's a good reader. I didn't assume you knew ancient Greek. In fact, My assumption was otherwise given a few things I've noted. I was just trying to give you an example of what I was trying to find for the older Bohairic pronunciation.
There is a lot of things I would get from something like that as opposed to the files already here. I would not only get the correct pronunciation, including the variations for letter with multiple phonemic values in their correct contexts. I would also get the proper feel for intonation within not only the sentence, but also for the emotions given the right selection of texts. In other words the kinds of things pronouncing a list of words in isolation doesn't transmit.
Normally, when I'm working on a language I try to get something, the Bible if I can but a novel will do, in the way of an extensive recording I can listen to in order to immerse myself in the target language. If such isn't available, and I would be surprised to find it for Coptic given the small number of folks who "speak" it in any form other than liturgical recitation, then I try to find something like the files I linked. I learned Erasmian pronunciation for Greek and I'm in the process of learning both modern Greek pronunciation and the reconstructed system. That's how I came across those files.
My ultimate goal, for which I'm grateful for the help you are giving me even now, is to eventually be an amateur scholar of all the earliest languages the New Testament was translated into and to get my hands on the earliest texts of said languages one who isn't wealthy at all can get on the cheap. I've been a student of ancient Greek since the early 1990s and Latin well before that, Hebrew starting in the last decade, and have gathered the material to study both Bohairic and Sahidic Coptic, Syriac, and Gothic. At the moment I'm concentrating more on Coptic than Syriac or Gothic. In fact, I've put off the other two to lay the proper foundation in Coptic.
All that is because of a vow I made to myself many years ago. The resources have only just become available to me to keep faith with the vow. Well, enough long-windiness for now.
