learning to leyn/daven with Ashkenazic pronunciation

I am a convert with some patrilineal Ashkenazi background. I am no longer a member of the shul where I did my conversion education. I have recently become more involved in a local kehilla where a friend has taught me to leyn a little bit. The kehilla's services draw from a wide variety of nusachim and minhagim, as the community is quite diverse.

When I am leyning, my preference would be to use an Ashkenazic pronunciation, but the learning materials available to me tend to prefer what I'll call an Israeli-American pronunciation, which I'm not particularly a fan of for reasons I won't go into here. I am therefore looking for materials that can help me learn a consistent Ashkenazic pronunciation for the purpose of leyning. I have a background in linguistics, so academic materials or others that assume competence with reading IPA would be quite welcome.

And yes, I am aware that there is quite a variety of Ashkenazic accents. However, I have had trouble finding *any* materials on this, so I'm not picky.

TL;DR: looking for materials to teach Ashki pronunciation for the purposes of leyning
