OK , so  um , Something I asked  So they 're  they 're doing  the  the VAD I guess they mean voice activity detection So again , it 's the silence  So they 've just trained up a net  which has two outputs , I believe. Um  I asked uh  Hynek whether  I haven't talked to Sunil  I asked Hynek whether  they compared that to  just taking the nets we already had  and summing up the probabilities.
Mm - hmm.
Uh.  To get the speech  voice activity detection , or else just using the silence ,  if there 's only one  silence output. Um  And , he didn't think they had , um. But on the other hand , maybe they can get by with a smaller net and  maybe  sometimes you don't run the other , maybe there 's a computational advantage to having a separate net , anyway.
Mm - hmm.
