not to my knowledge
normally i dont look for them either.
I posted a weird deal many mths ago when I got a LMH voice into a Mahler piece, oddly titled (in translation "Songs on the Deaths of Children.) A haunting work already but, somehow, in my merging (or EVP) a bit of a LMH show "appeared" when listening! I blamed my bad knowledge of Audacity and old computer running Linux and, somehow, some artifact got thrown it (the pieces I was attempting to merge were many so that I could have a total piece of the Mahler's work versus track1 track2 etc etc.) BUT it didn't merge a WHOLE LMH show or anything but after a few moments of music her speaking cut in and she had sentences and then cut back to Mahler and chorus etc. Very weird. But, again, I blamed out laptop, audacity, or me....
