Hmm ?
And , maybe , talking with Stephane and with Sunil , we decide that maybe it was interesting to  to apply on - line normalization before applying VTS. But then  we decided that that 's  it doesn't work absolutely , because we modified also the noise. And  Well , thinking about that , we  we then  we decide that maybe is a good idea. We don't know. I don't hav I don't  this is  I didn't  do the experiment yet  to apply VTS in cepstral domain.
The other thing  is  So  so , in  i i and  Not  and C - zero would be a different  So you could do a different normalization for C - zero than for other things anyway. I mean , the other thing I was gonna suggest is that you could have  two kinds of normalization with  with , uh , different time constants. So , uh , you could do some normalization  s uh , before the VTS , and then do some other normalization after. I don't know. But  but C - zero certainly acts differently than the others do ,
Uh.
