Yeah.
um , and the , uh  e the fraction of the energy that 's in the harmonic sequence that you 're looking at is relatively low , then it should be  then it 's more likely to be an overlap.
Is height. Yeah. This  this is the idea  the idea I  I  I had to  to compare the  the ratio of the   the energy of the harmonics with the  eh , with the , eh , total energy in the spectrum and try to get a ratio to  to distinguish between overlapping and speech. Mmm.
But you 're looking a y you 're looking at  Let 's take a second with this. Uh , uh , you 're looking at f at the phase derivative , um , in  in , uh , what domain ? I mean this is  this is in  in  in  in bands ? Or  or
