Phase modulated Formant Oscillators. I never would have imagined it would sound like this

In searching for smarter, more interesting FM modulators I started experimenting with phase modulating multiple aspects of a few formant oscillators, I can't believe the sound this creates.
Oh yeah, Frequency modulation and phase modulation are the same thing, I will be using both terms...
I think I'm just going to record myself messing around with it, practically speaking it is not parameter-intensive, or time-consuming once you know where to start.
