i is  if  If you have a good voice activity detector , isn't  isn't it gonna pull that out ?
Yeah. Sure. If they are good. Yeah. Well what it  it shows is that , yeah , perhaps a good voice activity detector is  is good before on - line normalization and that 's what uh  we 've already observed. But uh , yeah , voice activity detection is not   an easy thing neither.
But after you do this , after you do the variance normalization  I mean.
Mm - hmm.
