I'm listening to this now, didn't notice it before (I've been really busy). Thanks for making this.
Your voice is clear and easy to listen too
Think of the names of the angels. Azriel, not Aw-zriel. So that one is correct as Junkyard Dog pronounced it, unless the rabbis pronounce it as "Aw" when charging the name.
But I do think the "RUU" could be either, as Uriel could be pronounced as Ooriel.
If they are a bit off, it's fine.
And of course, add vibration. This is a guide to hear it clearly, but even stated like this will have an effect.
