Um  Yeah , so the idea was to train all the databases and obtain an alignment to train on these databases , and , um , also to , um , try different kind of features ,  uh , as input to the VAD network. And we came up with a bunch of features that we want to try like , um , the spectral slope , the , um , the degree o degree of voicing with the features that , uh , we started to develop with Carmen , um , e with , uh , the correlation between bands and different kind of features ,
Yeah. Mm - hmm.
and  Yeah.
