Vortex Sound Research

This may be weirdly specific, but I can't find a resource that isn't very technical to show what I want to do. I want to synthesize an "Om" sound, as in like a yogi meditation sound. It's surprisingly easy to make an "Oy" sound with a resonant bandpass filter, and feel like I ought to be able to shape the consonants with volume envelopes, but I can't quite get it to work.

FWIW, I have rings, ripples and qu-bit prism, each of which I can get vocal-ish sounds out of but I don't have the know-how to make them make the vocal sounds I want. Anybody make this work?
