But anyway. Um. Yeah , yeah. We have , yeah , extracted actually the noises from  the SpeechDat - Car. And so , we can train neural network with speech and these noises. Um. It 's difficult to say what it will give , because when we look at the Aurora  the TI - digits experiments , um , they have these three conditions that have different noises , and apparently this system perform as well on the seen noises  on the unseen noises and on the seen noises. But , I think this is something we have to try anyway. So  adding the noises from  from the SpeechDat - Car. Um.
That 's  that 's , uh  that 's permitted ?
Uh. Well , OGI does  did that. Um. At some point they did that for  for the voice activity detector.
Uh , for a v VAD.
