Uh - huh.
which is like final filter is acting on the input noisy speech rather than on the cleaned up. So this is more like I 'm doing Wiener filter twice , but the only thing is that the second time I 'm actually smoothing the filter and then cleaning up the cleaned up spectrum first level. And so that  that 's  that 's what the difference is.
OK.
And actually I tried it on s the original clean  I mean , the original spectrum where , like , I  the second time I estimate the filter but actually clean up the noisy speech rather the c s first  output of the first stage and that doesn't  seems to be a  giving , I mean , that much improvement. I  I didn didn't run it for the whole case. And  and what I t what I tried was , by using the same thing but  Uh , so we actually found that the VAD is very , like , crucial. I mean , just by changing the VAD itself gives you the  a lot of improvement
