OK Uh Alright So I uh uh wanted to mention a couple little bits of news Um Hynek is supposed to come for a couple days next week Don't know which days yet So hopefully have some intensive time to to work with people Um The second thing is that um starting to talk about maybe having Sunil come here uh for some chunk of the summer So that may or may not happen but if he does since actually Pratibha is going to be off at IBM um the uh effort will pretty much shift here cuz Sunil will be here and other people are working on other things I think So So Uh my news Alright Cool I need a new office mate Oh OK Yeah cool There you go Right It will be some sometime in summer July or August Yeah I mean it may not happen I mean he wants uh I think he wants some experience someplace else and uh thinking of going someplace but I mean Pratibha is getting her experience going to IBM and he may come here So But y I don't know maybe June Maybe earlier But uh Anyway Hynek will be here next week and maybe know more about it Oh yeah Well the news more specifically t for Aurora um So I guess there was again a conference call but uh they are not decide on everything yet For the VAD they probably they will do something like having some kind of idealized VAD that they could run on the channel zero of the and then take the same um end points and apply them on channel one so Oh so take a real VAD but apply it to g to to the clean Yeah to the clean and clean take data end points for the noisy Mmm OK But I am not sure this is decided yet Um and i when talking about it do you have the impression that talking about a particular VAD which everybody would use or or just that everybody would use the same procedure Well probably uh s the same VAD for everybody Um So they would just provide that as part of the data Maybe But this is still Yeah Sounds like still arguing Yeah Yeah still Yeah not decided Yeah Um I don't know what Yeah Nothing much Yeah Probably the um these weight things they will apply the same kind of weighting scheme for than for the So it would be weighting of um It would be an average of improvements rather than an average of word error rates which would make the more clean parts of more important than they are right now OK Uh but it sounds like none of this is really decided that this is how This things are leaning and they t I think they will tend to go this way but hmm Uh Yeah if we have the result for the tandem with um MSG also So it was t Yeah there is no surpri there is no surprise Well so there is nor significant improvement Um Yeah basically all started to work on some kind of report for the work so not much Yeah more have results you have a lunch talk sometime in When next it week yeah Next week Oh OK How about the um the thing that you guys were working on before the uh Uh uh Oh yes But no This week I am begin to to write the report Ah on I stopped it You Interfered on it I see Yeah OK Uh So it sounds like basically things are slowing down a bit And and and trying to collate results and get something from it Yeah Yeah Um Yeah Right now Sunil seems i is in India actually Right Uh so there is no progress apparently from their side neither Right Um puts And on us to do it But sorry Kind of puts it on us to put more in then really Yeah I mean Uh was uh looking at the combination of uh spectral s subtraction approaches with what we had for instance Sunil was working on this OK Um He sent a bunch of a bunch of results uh but I don't know the status of this I guess it was just the result that he sent so Um was that again He just used the spectral subtraction and the LDA filters I guess Mmm And it was not better than what we had before Then he tried to put the normalization and it did not improve further putting the normalization so Um Yeah Hmm Huh OK Well Hmm Yeah I uh I g so I guess nothing has ever happened about uh making a standardized uh place where the software sits so that people can work with it and No upgrade Well it I I sent mails to start the the process and I guess we should have to Well we know most what we have to to put in in this And Yeah So I guess Yeah we m OK Well uh come back to this uh later Um OK Um Chuck did you get a chance to do anymore stuff with the uh No I didn't Um are you talking about HTK or Uh no This week I haven't been my whole been taken up with uh Meeting Recorder stuff OK Uh disk crash and u uh OK covering things This may be a very short meeting Uh Um Anything from your Uh side continuing readings we come Uh doing some background reading on phonetics OK Yeah Dave Well um One thing in in the paper Avendano and his collaborators wrote is that is that um they tried doing channel normalization on the reverberant in speech by um subtracting the mean of the log spectral magnitude over a two second window But they didn't do anything with the phase and they said perhaps that limited their approach that it did not try to normalize the phase in any way So going to start thinking about um ways that the ph that the phase could be used Um Si if if the um channel and the reverberation is multiplicative in the frequency domain with the speech spectrum then the phases should be additive So um perhaps just subtracting the mean of the phase would would help Um but I don't know I th I get the impression that they tried to do some things with the phase and they weren't successful OK Oh You know there is one other thing Um Stephane showed me a paper yesterday um where th uh for the Italian system they had done a series of experiments playing around with the um the number of iterations that I talked about last week And um so there was a whole series of those that they had done They didn't I don't think reported timing for those but um
