And these artificial distortions  uh , I have the feeling that they are the reason why  why we have the problems in this multi - condition training. That means the H M Ms we trained , they are  they are based on Gaussians ,
Yeah.
and on modeling Gaussians. And if you  Can I move a little bit with this ? Yeah. And if we introduce now this  this u spectral subtraction , or Wiener filtering stuff  So , usually what you have is maybe , um  I 'm  I 'm showing now an envelope um maybe you 'll  f for this time. So usually you have  maybe in clean condition you have something which looks like this. And if it is noisy it is somewhere here. And then you try to subtract it or Wiener filter or whatever. And what you get is you have always these problems , that you have this  these  these  these zeros in there.
Yeah.
