It’s all to do with creating vowels which have harsh clusters of harmonics that come together to create a second note on top of the normal note. So the unusual vowel that she’s making there (high, tense tongue and closed lips) create this strange, piercing sound, which she then fluctuates and controls with her lips. It’s really frigging tough to control – but if you imitate her you might be able to hear a slight ring of harmonics on there? I’ve been trying it all morning and only managed to get a tiny, tiny bit – this gal got game.

Don’t know if anyone has encountered this, but on an analogue synthesiser (which I’ve always found to be a good image for acoustic aspects of the voice), there is a control for ‘resonance’ (clumsily named IMO) which can boost the frequencies around the low-pass filter cutoff frequency (set by a different control). WIth resonance at 0 (and with a dash of imagination), moving the filter cutoff changes the sound somewhat lazily from an ‘ooh’ to an ‘aah’. Boosting the resonance seems to exaggerate the perceived change in vowel, more like an ‘aaw’ to an ‘eee’ (presumably an important acoustic aspect of forming and perceiving vowels then). If this control is set high enough, individual harmonics become audible as the filter sweeps across them. That ties in exactly with what Matt said, but might provide a nice visualisation for this phenomenon! Here is a link to a demonstration of this on a synth (I have seen one with a better explanation but I couldn’t find it). https://www.youtube.com/watch?v=DAoGvI3_Nzg
