because it  it  well , this VAD uh either some delay and we  if we put it on the server side , it doesn't work , because on the server side features you already have LDA applied  from the f from the terminal side and  so you accumulate the delay so the VAD should be before the LDA which means perhaps on the terminal side and then smaller  and
So wha where did this good VAD come from ?
So. It 's um from OGI. So it 's the network trained  it 's the network with the huge amounts on hidden  of hidden units , and um nine input frames compared to the VAD that was in the proposal which has a very small amount of hidden units and fewer inputs.
This is the one they had originally ?
