So , um ,  I guess I 'll just pass it on to Dave.
Uh , OK. Well , in my lunch talk last week I  I said I 'd tried phase normalization and gotten garbage results using that l um , long - term mean subtraction approach. It turned out there was a bug in my Matlab code. So I tried it again , um , and , um , the results  were  were better. I got intelligible speech back. But they still weren't as good as just subtracting the magnitude  the log magnitude means. And also I 've been talking to , um , Andreas and Thilo about the , um , SmartKom language model and about coming up with a good model for , um , far mike use of the SmartKom system. So I 'm gonna be working on , um , implementing this mean subtraction approach in the  far - mike system  for the SmartKom system , I mean. And , um , one of the experiments we 're gonna do is , um , we 're gonna , um , train the  a Broadcast News net , which is because that 's what we 've been using so far , and , um , adapt it on some other data. Um , An - Andreas wants to use , um , data that resembles read speech , like  these digit readings , because he feels that the SmartKom system interaction is not gonna be exactly conversational.
Mm - hmm.
S so actually I was wondering , how long does it take to train that Broadcast News net ?
