Mmm.
Mmm  Yeah. Then , uh , whhh well , I 've been working on  on t mainly on on - line normalization this week. Uh , I 've been trying different  slightly  slightly different approaches. Um , the first thing is trying to play a little bit again with the , um , time constant. Uh , second thing is , uh , the training of , uh , on - line normalization with two different means , one mean for the silence and one for the speech. Um , and so I have two recursions which are controlled by the , um , probability of the voice activity detector. Mmm. This actually don't s doesn't seem to help , although it doesn't hurt. So. But  well , both  on - line normalization approach seems equivalent. Well , they
Are the means pretty different  for the two ?
