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.
I don't know , it seems like this would be a lot easier than this signal to work with.
