QMSum_86
false
Um. So Uh I just sorta think we need to explore the space. Just take a look at it a little bit.
QMSum_86
false
Mm - hmm.
QMSum_86
false
And we we we may just find that that we 're way off.
QMSum_86
false
OK. Mm - hmm.
QMSum_86
false
Maybe we 're not. You know ? As for these other things , it may turn out that , uh , it 's kind of reasonable. But then I mean , Andreas gave a very reasonable response , and he 's probably not gonna be the only one who 's gonna say this in the future of , you know , people people within this tight - knit community who are doing this evaluation are accepting , uh , more or less , that these are the rules. But , people outside of it who look in at the broader picture are certainly gonna say " Well , wait a minute. You 're doing all this standing on your head , uh , on the front - end ,
QMSum_86
false
Yeah.
QMSum_86
false
when all you could do is just adjust this in the back - end with one s one knob. "
QMSum_86
false
Mm - hmm.
QMSum_86
false
And so we have to at least , I think , determine that that 's not true , which would be OK , or determine that it is true , in which case we want to adjust that and then continue with with what we 're doing. And as you say as you point out finding ways to then compensate for that in the front - end also then becomes a priority for this particular test ,
QMSum_86
false
Right.
QMSum_86
false
and saying you don't have to do that.
QMSum_86
false
Mm - hmm.
QMSum_86
true
So. OK. So , uh What 's new with you ?
QMSum_86
false
Uh. So there 's nothing new. Um.
QMSum_86
false
Uh , what 's old with you that 's developed ?
QMSum_86
false
I 'm sorry ?
QMSum_86
false
You OK. What 's old with you that has developed over the last week or two ?
QMSum_86
false
Mmm. Well , so we 've been mainly working on the report and and Yeah.
QMSum_86
false
Mainly working on what ?
QMSum_86
false
On the report of the work that was already done.
QMSum_86
false
Oh.
QMSum_86
false
Um. Mm - hmm. That 's all.
QMSum_86
false
How about that ? Any - anything new on the thing that , uh , you were working on with the , uh ?
QMSum_86
false
I don't have results yet.
QMSum_86
false
No results ? Yeah.
QMSum_86
false
What was that ?
QMSum_86
false
The the , uh ,
QMSum_86
false
Voicing thing.
QMSum_86
false
voicing detector.
QMSum_86
false
I mean , what what 's what 's going on now ? What are you doing ?
QMSum_86
false
Uh , to try to found , nnn , robust feature for detect between voice and unvoice. And we w we try to use the variance of the es difference between the FFT spectrum and mel filter bank spectrum.
QMSum_86
false
Yeah.
QMSum_86
false
Uh , also the another parameter is relates with the auto - correlation function.
QMSum_86
false
Uh - huh.
QMSum_86
false
R - ze energy and the variance a also of the auto - correlation function.
QMSum_86
false
Uh - huh. So , that 's Yeah. That 's what you were describing , I guess , a week or two ago.
QMSum_86
false
Yeah. But we don't have res we don't have result of the AURO for Aurora yet.
QMSum_86
false
So.
QMSum_86
false
We need to train the neural network
QMSum_86
false
Mm - hmm.
QMSum_86
false
and
QMSum_86
false
So you 're training neural networks now ?
QMSum_86
false
No , not yet.
QMSum_86
false
So , what wha wh wha what what 's going on ?
QMSum_86
false
Well , we work in the report , too , because we have a lot of result ,
QMSum_86
false
Uh - huh.
QMSum_86
false
they are very dispersed , and was necessary to to look in all the directory to to to give some more structure.
QMSum_86
false
Yea
QMSum_86
false
So. B So Yeah. I if I can summarize , basically what 's going on is that you 're going over a lot of material that you have generated in furious fashion , f generating many results and doing many experiments and trying to pull it together into some coherent form to be able to see wha see what happens.
QMSum_86
false
Hm - hmm.
QMSum_86
false
Uh , y yeah. Basically we we 've stopped , uh , experimenting ,
QMSum_86
false
Yes ?
QMSum_86
false
I mean. We 're just writing some kind of technical report. And
QMSum_86
false
Is this a report that 's for Aurora ? Or is it just like a tech report for ICSI ,
QMSum_86
false
No.
QMSum_86
false
Yeah.
QMSum_86
false
For ICSI.
QMSum_86
false
or ? Ah. I see.
QMSum_86
false
Yeah.
QMSum_86
false
Just summary of the experiment and the conclusion and something like that.
QMSum_86
false
Yeah.
QMSum_86
false
Mm - hmm.
QMSum_86
false
OK. So , my suggestion , though , is that you you not necessarily finish that. But that you put it all together so that it 's you 've got you 've got a clearer structure to it. You know what things are , you have things documented , you 've looked things up that you needed to look up.
QMSum_86
false
Mm - hmm.
QMSum_86
false
So that , you know so that such a thing can be written. And , um When when when do you leave again ?
QMSum_86
false
Uh , in July. First of July.
QMSum_86
false
First of July ? OK. And that you figure on actually finishing it in in June. Because , you know , you 're gonna have another bunch of results to fit in there anyway.
QMSum_86
false
Mm - hmm.
QMSum_86
false
Mm - hmm.
QMSum_86
false
And right now it 's kind of important that we actually go forward with experiments.
QMSum_86
false
It 's not.
QMSum_86
false
So so , I I think it 's good to pause , and to gather everything together and make sure it 's in good shape , so that other people can get access to it and so that it can go into a report in June. But I think to to really work on on fine - tuning the report n at this point is is probably bad timing , I I think.
QMSum_86
false
Mm - hmm. Yeah. Well , we didn't we just planned to work on it one week on this report , not no more , anyway. Um.
QMSum_86
false
But you ma you may really wanna add other things later anyway
QMSum_86
false
Yeah. Mm - hmm.
QMSum_86
false
because you
QMSum_86
false
Mmm.
QMSum_86
false
There 's more to go ?
QMSum_86
false
Yeah. Well , so I don't know. There are small things that we started to to do. But
QMSum_86
false
Are you discovering anything , uh , that makes you scratch your head as you write this report , like why did we do that , or why didn't we do this ,
QMSum_86
false
Uh.
QMSum_86
false
or ?
QMSum_86
false
Yeah. Yeah. And Actually , there were some tables that were also with partial results. We just noticed that , wh while gathering the result that for some conditions we didn't have everything.
QMSum_86
false
Mmm.
QMSum_86
false
But anyway. Um. Yeah , yeah. We have , yeah , extracted actually the noises from the SpeechDat - Car. And so , we can train neural network with speech and these noises. Um. It 's difficult to say what it will give , because when we look at the Aurora the TI - digits experiments , um , they have these three conditions that have different noises , and apparently this system perform as well on the seen noises on the unseen noises and on the seen noises. But , I think this is something we have to try anyway. So adding the noises from from the SpeechDat - Car. Um.
QMSum_86
false
That 's that 's , uh that 's permitted ?
QMSum_86
false
Uh. Well , OGI does did that. Um. At some point they did that for for the voice activity detector.
QMSum_86
false
Uh , for a v VAD.
QMSum_86
false
Right ? Um.
QMSum_86
false
Could you say it again ? What what exactly did they do ?
QMSum_86
false
They used some parts of the , um , Italian database to train the voice activity detector , I think. It
QMSum_86
false
Yeah. I guess the thing is Yeah. I guess that 's a matter of interpretation. The rules as I understand it , is that in principle the Italian and the Spanish and the English no , Italian and the Finnish and the English ? were development data
QMSum_86
false
Yeah. And Spanish , yeah.
QMSum_86
false
on which you could adjust things. And the and the German and Danish were the evaluation data.
QMSum_86
false
Mm - hmm.
QMSum_86
false
And then when they finally actually evaluated things they used everything.
QMSum_86
false
Yeah. That 's right. Uh
QMSum_86
false
So Uh , and it is true that the performance , uh , on the German was I mean , even though the improvement wasn't so good , the pre the raw performance was really pretty good.
QMSum_86
false
Mm - hmm.
QMSum_86
