OK OK so We we had a meeting with uh with Hynek um in in which uh uh Sunil and Stephane uh summarized where they were and and uh talked about where we were gonna go So that that happened sort of D did Uh you guys get your code Oh yeah pushed together Yeah Cool it was updated yesterday right Yeah Yeah Oh right I saw You I probably the received note mail Yeah What was the update What was the update Yeah So there is th then the all the new features that go in The um noise suppression the of speech after suppression Is the These um the Yeah the CVS mechanism working well Are are people uh up at OGI grabbing code uh via that Or Uh I don't think I I don't don't know think they use it but Yeah I I don't think anybody up there is like working on it right now Mmm think it more likely that what it means is that when Sunil is up there Yeah he will grab it Yeah Yeah So right now working on Aurora there I see Yeah I see working on a different task Yeah OK But happen is is go back up there and uh Pratibha will come back from from uh the east coast Uh And uh and and I guess actually uh after Eurospeech for a little bit uh go up there too So actually everybody working on it will be up there for at least a little while So remotely access it So has Has anybody tried remotely accessing the CVS using uh uh SSH Um I don't know if Hari did that or I d actually do it today I mean I can just log into Have you tried it yet No I didn't OK So I try Good it idea Yeah Yeah Actually I I tried wh while when I installed the repository I tried from Belgium I Yeah logged in there and I tried It worked import Yeah it works good Great Oh But So right now the mechanism with SSH I don't s I didn't set up You can also set up a CVS server on a new port like Yeah Right uh a main server or d You can do a CVS server Then using the CVS password mechanism and all that right right But I didn't do that because I was not sure about security problems I So would w have to when you came in from Belgian Belgium using SSH uh was it asking you for your own password into ICSI So if yo you can Right if you have an account at ICSI OK Yeah Cuz there is an a way to set up anonymous CVS right So that Yeah you ha in this way you ca you have to set up a CVS server but then yeah you can access it Oh OK So the you anonymous can mechanism priorities You can access them and mostly if you if OK the server Because is lot up the like open source stuff works with anonymous CVS and just wondering Uh I mean for our transcripts we may want to do that Yeah Uh Yeah for this stuff I don't think quite up to that I mean still so Yeah development yeah want to have just the Oh insiders suggesting for this thinking of the Meeting Recorder stuff but Yeah Yeah OK Cool Yeah So uh new Well I mean I think maybe the thing to me might be I me sure just been working on on uh details of that since the meeting right And so Mmm since the meeting That well was I that been was Tuesday train training a new VAD and a new feature net OK So they should be ready Um But I guess maybe the thing since you weren't yo you guys weren't at that that meeting might be just just to um sort of recap uh the the conclusions of Oh meeting talking about So meeting with Hynek Yeah Cuz that was sort of uh we sort of been working up to that that that uh he would come here this week and and we would sort of Since going out of town like now and going out town in a couple weeks uh and time is marching sort of given all the mu many wonderful things we could be working on what what will we actually focus on And uh and what do we freeze And you know what do we So um I mean this software that these guys created was certainly a a key part So then something central and there aren't at least a bunch of different versions going off in in ways that differ trivially Yeah Uh um and um nice and then within that I guess the idea was to freeze a certain set of options for now to run it uh a particular way and decide on what things are gonna be experimented with as opposed to just experimenting with everything So keep a certain set of things constant So um Uh maybe describe roughly what what we are keeping constant for now or Yeah Well So been working like six weeks on on the noise compensation and we end up with something that seems reasonable Um Are you gonna use which of the two techniques So finally um Wiener filtering on FFT bins And it uses uh two steps smoothing of the transfer function the first step along time which use recursion And after this step there is a further smoothing along frequency which use a sliding window of twenty FFT bins Mmm And uh on the uh before any mel scaling has been Yeah done This yeah is This was this Yeah smoothing is done on the estimate um of what going to subtract Or on the thing that has already had something subtracted Uh on the transfer function So Oh on the transfer function for the Wiener filter Yeah Yeah OK Yeah so basically we tried different configuration within this idea We tried u u applying this on mel bands having spectral subtraction instead of wiener filtering Um Well finally we end up with this configuration that works uh quite well So we are going to fix this for the moment and work on the other aspects of the whole system So Actually let me int eh Dave isn't here to talk about it but let me just interject This module in principle i I mean you would know whether true in fact is somewhat independent from the rest of it I mean because you you speech right So um Uh well you don't I guess you don't speech We you we could not fo Uh but you could Well well we do but we don't don't In in the program we don't and then once again We just use the clean FFT bins But you have a This thing an that option that an an then option can Yeah
