uh , which would smooth things a bit for those occasions when , uh , the testing set was quite different than what you 'd trained your discriminant features for. So , um , all of that is  is , uh  still seems like a good idea. The thing is now we know some other constraints. We can't have unlimited amounts of latency. Uh , y you know , that 's still being debated by the  by people in Europe but ,  uh , no matter how they end up there , it 's not going to be unlimited amounts ,
Yeah.
so we have to be a little conscious of that. Um. So there 's the neural net issue. There 's the VAD issue. And , uh , there 's the second stream  thing. And I think those that we  last time we agreed that those are the three things that have to get , uh , focused on.
What was the issue with the VAD ?
