For this it might help , um
Mm - hmm.
S so , yeah. Uh , so yeah , the next thing I started to do is to ,  uh , try to develop a better voice activity detector. And , um  I d um  yeah , for this I think we can maybe try to train the neural network for voice activity detection on all the data that we have , including all the SpeechDat - Car data. Um  And so I 'm starting to obtain alignments on these databases. Um , and the way I mi I do that is that I just use the HTK system but I train it only on the close - talking microphone. And then I aligned  I obtained the Viterbi alignment of the training utterances. Um  It seems to be , uh i Actually what I observed is that for Italian it doesn't seem  Th - there seems to be a problem.
No. So , it doesn't seems to help by their use of channel zero or channel one.
