input: Text: Professor B: OK So uh today we're looking at a number of uh things we're trying and uh fortunately for listeners to this uh we lost some of it's visual but um got tables in front of us. Um what is <unk>disfmarker<unk> what does combo mean? PhD C: So combo is um a system where we have these features that go through a network and then this same string of features but low - pass filtered with the low - pass filter used in the MSG features. And so these low - pass filtered goes through M eh <unk>disfmarker<unk> another MLP and then the linear output of these two MLP's are combined just by adding the values and then there is this KLT. Um the output is used as uh features as well. Professor B: Um so let me try to restate this and see if I have it right. There is uh <unk>disfmarker<unk> there is the features uh there's the OGI features and then um those features um go through a contextual <unk>disfmarker<unk> uh l l let's take this bottom arr one pointed to by the bottom arrow. Um those features go through a contextualized KLT. Then these features also uh get um low - pass filtered PhD C: Yeah. Yeah so yeah I could perhaps draw this on the blackboard Professor B: Sure. Yeah. Yeah. PhD C: Yeah. PhD D: The graph, yeah another one. Professor B: Yeah, that's good. PhD C: Professor B: So PhD C: So we have these features from OGI that goes through the three paths. Professor B: Yeah. Three, OK. PhD C: The first is a KLT using several frames of the features. Professor B: Yeah. Yeah. PhD C: The second path is uh MLP also using nine frames <unk>disfmarker<unk> several frames of features Professor B: Yeah. Uh - huh. PhD C: The third path is
  Question: What did PhD C think about silence detection?
  Answer:
output: PhD C explained that there was no room left for silence detection because of the server side delay. They were working out a compromise between the handset delay and the server delay, but the delay was too large at the moment.
