Yeah , it is.
I think what 's really interesting though , it is  before d  saying " yes , meetings have a lot of overlaps " is to actually find out how many more  we have than two - party.
I think so too , I think
Cuz in two - party conversations , like Switchboard , there 's an awful lot too if you just look at backchannels , if you consider those overlaps ? it 's also ver it 's huge. It 's just that people haven't been  looking at that because they 've been doing single - channel processing for  speech recognition.
