Without taking care of consistent tuning or tempo. It was really an effort well beyond their capability. I spent most of a day retuning little pieces and re-aligning them in Ardour.

Some vowels can have harmonics that are much stronger than the fundamental, resulting in strong peaks in the autocorrelation (used for pitch detection) corresponding to an harmonic. But the autocorrelation also always has peaks at subharmonics of the fundamental. So you can end up with very ambiguous hints at what the actual fundamental is. Long vowels can be very useful to test and optimise how this is handled.
