Sure.
because when it 's a b backchannel could well happen in a very densely populated overlap. And if we 're gonna study types of overlaps , which is what I wanna do , an analysis of that , then that really does require listening  to every single channel all the way through the entire  length for all the different speakers. Now , for only four speakers , that 's not gonna be too much time , but if it 's nine speakers , then that i that is more time. So it 's li you know , kind of wondering  And I think again it 's like this  it 's really valuable that Thilo 's working on the speech - nonspeech segmentation because maybe , um , we can close in on that wi without having to actually go to the time that it would take to listen to every single channel from start to finish through every single meeting.
Yeah , but those backchannels will always be a problem I think. Uh especially if they 're really short and they 're not very loud and so it  it can  it  it will always happen that also the automatic s detection system will miss some of them , so.
OK. Well so then  then , maybe the answer is to , uh , listen especially densely in places of overlap ,
