You know , the  the Aurora baseline is set up with these , um   this version of the clean training set that 's been filtered with this G - seven - one - two filter , and , um , to train the SRI system on digits S - Andreas used the original TI - digits , um , under U doctor - speech data TI - digits , which don't have this filter. But I don't think there 's any other difference.

So is that  ? Uh , are  are these results comparable ? So you  you were getting with the , uh , Aurora baseline something like two point four percent  on clean TI - digits , when , uh , training the SRI system with clean TR digits   TI - digits. Right ? And


So is that  ? Uh , are  are these results comparable ? So you  you were getting with the , uh , Aurora baseline something like two point four percent  on clean TI - digits , when , uh , training the SRI system with clean TR digits   TI - digits. Right ? And

Yeah. And , so , is your two point seven comparable , where you 're , uh , uh , using , uh , the submitted system ?


Yeah. And , so , is your two point seven comparable , where you 're , uh , uh , using , uh , the submitted system ?


The complete SRI system is one point two.


OK , so  the comparable number then , uh  for what you were talking about then , since it was HTK , would be the  um , two point f


OK , so  the comparable number then , uh  for what you were talking about then , since it was HTK , would be the  um , two point f

It was four point something. Right ? The HTK system with , uh , b


It was four point something. Right ? The HTK system with , uh , b


Do you mean the b ? The baseline Aurora - two system , trained on TI - digits , tested on Meeting Recorder near , I think we saw in it today , and it was about six point six percent.

So  Yeah. The only difference is the features , right now , between this and


So  Yeah. The only difference is the features , right now , between this and


They are helping. Yeah. Um. Yeah. And another thing I  I maybe would like to do is to  just test the SRI system that 's trained on Macrophone  test it on , uh , the noisy TI - digits ,


They are helping. Yeah. Um. Yeah. And another thing I  I maybe would like to do is to  just test the SRI system that 's trained on Macrophone  test it on , uh , the noisy TI - digits ,

cuz I 'm still wondering  where this  improvement comes from. When you train on Macrophone , it seems better on meeting digits. But I wonder if it 's just because maybe  Macrophone is acoustically closer to the meeting digits than  than TI - digit is , which is  TI - digits are very  clean recorded digits

You 'd have to train the SRI system with  with all the different languages.

That 's true , but I think that also when we 've had these meetings week after week , oftentimes people have not done the full arrange of things

But  Mmm. Yeah. So I did  I just  started to test  putting together two VAD which was  was not much work actually.

and , detect detecting the first  group of four frames  that have a energy that 's above this threshold , and , uh , from this point , uh , tagging the frames there as speech.

just as a gross generalization , most nonsp many nonspeech noises have a low - pass kind of characteristic , some sort of slope. And  and most , um , low - energy speech components that are unvoiced have a  a high - pass kind of characteristic

So , yeah. It  it might be that what I did is  so , removes like  low , um ,  uh  low - energy , uh , speech frames. Because  the way I do it is I just  I just combine the two decisions  so , the one from the MLP and the one from the energy - based  with the  with the and  operator. So , I only  keep the frames where the two agree  that it 's speech. So if the energy - based dropped  dropped low - energy speech , mmm , they  they are  they are lost. Mmm.

Something that  that I 've used in the past is , um  when just looking at the energy , is to look at the derivative. And you  make your decision when the derivative is increasing for  so many frames. Then you say that 's beginning of speech.

And it seems to be the case. Um. Uh , the second thing is the  this spectral subtraction. Um. Um , which I 've just started yesterday to launch a bunch of , uh ,  twenty - five experiments , uh , with different , uh , values for the parameters that are used. So , it 's the Makhoul - type spectral subtraction which use  an over - estimation factor. So , we substr I subtract more ,   um ,   noise than the noise spectra that  is estimated  on the noise portion of the s uh , the utterances. So I tried several , uh , over - estimation factors. And after subtraction , I also add  a constant noise , and I also try different , uh ,  noise , uh , values and we 'll see what happen.

Mm - hmm. Mm - hmm. But st still when we look at the , um  Well , it depends on the parameters that you use , but for moderate over - estimation factors and moderate noise level that you add , you st have a lot of musical noise. Um. On the other hand , when you  subtract more and when you add more noise , you get rid of this musical noise but  maybe you distort a lot of speech. So. Well. Mmm. Well , it  until now , it doesn't seem to help. But We 'll see. So the next thing , maybe I  what I will  try to  to do is just  to try to smooth mmm ,  the , um  to smooth the d the result of the subtraction , to get rid of the musical noise , using some kind of filter , or

OK. So , uh  u th I 've been playing with this Wiener filter , like. And there are  there were some bugs in the program , so I was p initially trying to clear them up. Because one of the bug was  I was assuming that always the VAD  uh , the initial frames were silence. It always started in the silence state , but it wasn't for some utterances. So the  it wasn't estimating the noise initially , and then it never estimated , because I assumed that it was always silence.

SpeechDat - Car Italian. Yeah. There 're a few cases , actually , which I found later , that there are.

So that was one of the  bugs that was there in estimating the noise. And , uh , so once it was cleared , uh , I ran a few experiments with  different ways of smoothing the estimated clean speech and how t estimated the noise and , eh , smoothing the SNR also. And so the  the trend seems to be like ,  uh , smoothing the  current estimate of the clean speech for deriving the SNR , which is like  deriving the Wiener filter , seems to be helping. Then updating it quite fast using a very small time constant. So we 'll have , like , a few results where the  estimating the  the  More smoothing is helping. But still it 's like  it 's still comparable to the baseline. I haven't got anything beyond the baseline. But that 's , like , not using any Wiener filter. And , uh , so I 'm  I 'm trying a few more experiments with different time constants for smoothing the noise spectrum , and smoothing the clean speech , and smoothing SNR. So there are three time constants that I have. So , I 'm just playing around. So , one is fixed in the line , like  Smoothing the clean speech is  is helping , so I 'm not going to change it that much. But , the way I 'm estimating the noise and the way I 'm estimating the SNR , I 'm just trying  trying a little bit. So , that h And the other thing is , like , putting a floor on the , uh , SNR , because that  if some  In some cases the clean speech is , like  when it 's estimated , it goes to very low values , so the SNR is , like , very low. And so that actually creates a lot of variance in the low - energy region of the speech. So , I 'm thinking of , like , putting a floor also for the SNR so that it doesn't  vary a lot in the low - energy regions. And , uh. So. The results are , like  So far I 've been testing only with the  baseline , which is  which doesn't have any LDA filtering and on - line normalization. I just want to separate the  the contributions out. So it 's just VAD , plus the Wiener filter , plus the baseline system , which is , uh , just the spectral  I mean , the mel sp mel , uh , frequency coefficients. Um. And the other thing that I tried was  but I just  took of those , uh ,   Carlos filters , which Hynek had , to see whether it really h helps or not. I mean , it was just a  a run to see whether it really degrades or it helps. And it 's  it seems to be like it 's not  hurting a lot by just blindly picking up one filter which is nothing but a  four hertz  a band - pass m m filter on the cubic root of the power spectrum. So , that was the filter that Hy - uh , Carlos had. And so  Yeah. Just  just to see whether it really  it 's  it 's  is it worth trying or not. So , it doesn't seems to be degrading a lot on that. So there must be something that I can  that can be done with that type of noise compensation also , which   I guess I would ask Carlos about that. I mean , how  how he derived those filters and  and where d if he has any filters which are derived on OGI stories , added with some type of noise which  what we are using currently , or something like that. So maybe I 'll

So , if you have this band - pass filter , you probably get n you get negative values. Right ?

Yeah. And I 'm , like , floating it to z zeros right now.

So it has , like  the spectrogram has , like  Uh , it actually , uh , enhances the onset and offset of  I mean , the  the begin and the end of the speech. So it 's  there seems to be , like , deep valleys in the begin and the end of , like , high - energy regions ,

There are a few  very  not a lot of  because the filter doesn't have a  really a deep negative portion , so that it 's not really creating a lot of negative values in the cubic root. So , I 'll  I 'll s may continue with that for some w I 'll  I 'll  Maybe I 'll ask Carlos a little more about how to play with those filters , and  but while  making this Wiener filter better. So.

Well , I am still working with , eh , VTS. And , one of the things that last week , eh , say here is that maybe the problem was with the diff because the signal have different level of energy.


Well , I am still working with , eh , VTS. And , one of the things that last week , eh , say here is that maybe the problem was with the diff because the signal have different level of energy.

And , maybe , talking with Stephane and with Sunil , we decide that maybe it was interesting to  to apply on - line normalization before applying VTS. But then  we decided that that 's  it doesn't work absolutely , because we modified also the noise. And  Well , thinking about that , we  we then  we decide that maybe is a good idea. We don't know. I don't hav I don't  this is  I didn't  do the experiment yet  to apply VTS in cepstral domain.

The other thing  is  So  so , in  i i and  Not  and C - zero would be a different  So you could do a different normalization for C - zero than for other things anyway. I mean , the other thing I was gonna suggest is that you could have  two kinds of normalization with  with , uh , different time constants. So , uh , you could do some normalization  s uh , before the VTS , and then do some other normalization after. I don't know. But  but C - zero certainly acts differently than the others do ,

Well , we s decide to m to  to obtain the new expression if we work in the cepstral domain. And  Well. I am working in that now ,

but  I 'm not sure if that will be usefu useful. I don't know. It 's k it 's k It 's quite a lot  It 's a lot of work.

Well , it 's not too much , but this  it 's work.


Well , it 's not too much , but this  it 's work.

And I want to know if  if we have some  feeling that  the result  I  I would like to know if  I don't have any feeling if this will work better than apply VTS aft in cepstral domain will work better than apply in m mel  in filter bank domain. I r I 'm not sure. I don't  I don't know absolutely nothing.

Yeah. Well , you 're  I think you 're the first one here to work with VTS , so , uh , maybe we could call someone else up who has , ask them their opinion. Uh ,


Yeah. Well , you 're  I think you 're the first one here to work with VTS , so , uh , maybe we could call someone else up who has , ask them their opinion. Uh ,

I don't  I don't have a good feeling for it. Um.


I don't  I don't have a good feeling for it. Um.

Actually , the VTS that you tested before was in the log domain and so  the codebook is e e kind of dependent on the  level of the speech signal.


Actually , the VTS that you tested before was in the log domain and so  the codebook is e e kind of dependent on the  level of the speech signal.

And  So I expect it  If  if you have something that 's independent of this , I expect it to  it  to , uh , be a better model of speech.


And  So I expect it  If  if you have something that 's independent of this , I expect it to  it  to , uh , be a better model of speech.


And  So I expect it  If  if you have something that 's independent of this , I expect it to  it  to , uh , be a better model of speech.

You  you wouldn't even need to switch to cepstra. Right ? I mean , you can just sort of normalize the


You  you wouldn't even need to switch to cepstra. Right ? I mean , you can just sort of normalize the

No. We could normali norm I mean , remove the median.


You  you wouldn't even need to switch to cepstra. Right ? I mean , you can just sort of normalize the

Yeah. Yeah. And then you have  one number which is very dependent on the level cuz it is the level ,


No. We could normali norm I mean , remove the median.

Yeah. Yeah. And then you have  one number which is very dependent on the level cuz it is the level ,


Yeah. Yeah. And then you have  one number which is very dependent on the level cuz it is the level ,

Mm - hmm. Yeah. But here also we would have to be careful about removing the mean  of speech and not of noise.


Mm - hmm. Yeah. But here also we would have to be careful about removing the mean  of speech and not of noise.

Sure. I mean , one of the things we 've talked about  maybe it might be star time to start thinking about pretty soon , is as we look at the pros and cons of these different methods , how do they fit in with one another ?

Um  like before we uh  I have to redo the meetings from   n th the minutes from the last meeting


Um  like before we uh  I have to redo the meetings from   n th the minutes from the last meeting

and so here we go. Uh it was discussed in the last meeting uh which was opened by the presentation from the interface um designer  that uh looks would be very important on this new remote


and so here we go. Uh it was discussed in the last meeting uh which was opened by the presentation from the interface um designer  that uh looks would be very important on this new remote

and um it is to send messages of course to the T_V_. It should have nine channel buttons , a next button , volume buttons , subtitle buttons , switch to control features , colour contrast , sharpness etcetera. It should have a memory switch , a mute button in case the telephone rings or something. Uh speech recognition is one of her very f favourite personal uh features she would like see d d to be integrated in this um in this new remote. Um.  Should be child friendly design with few buttons , colourful maybe with s star shaped or other shaped buttons. Um she uh presented also an oversized remote which she guarantees nobody will ever be able to lose.

But uh her very f personal favourite really she , she would very much like to see a speech recogniser integrated in this remote. The industrial designer um presented her uh  thoughts on the issue. She would like a special case made out of plastic that is very strong , not using any harmful materials , should be recyclable and should be colourful. Should have an integrated circuit board that's highly sophisticated and temperature resistant. She would like to see a timer and or alarm facility integrated. Uh technically this thing would also have a resistor and a capacitor , diode transistor , resonator , and if possible a rechargeable battery. Uh and of course a circuit board. And how it would works , you press the button , the chip is morse  morse code related relays the  uh to the generat to the generator amplification and uh the circuit board is very inexpensive to build and so she thinks this is a great feature uh to to to consider.

She would like uh  this whole thing should be push buttons with a simple chip uh scrolling method is more expensive and not that practical anymore. Should be battery operated and of course she would have the special cases. The marketing expert uh who has to finally come up with  to to to market this product has been watching the competition , has done some research on the internet and also has used h her personal observations to come up with the fact that such a remote sh should be small , easy to use and it should be eye catching. From her point of view of course one of the most important facts is that we should get to market before our competition does. To do that uh maybe one or two features should be developed on which we could dwell on or in other words on which our campaign could be built on. Too many new features or too many points would only confuse matter. So we prefer to have one or two features that can be really uh driven home. Um it should have a fruit and vegetable design and should have a soft feel. She feels that's really what people want today. And the decision that we took last time was that uh the special feature we would like to see is a speech recogniser , the energy should be battery uh should be on a chip , should be trendy design , compact and strong , and should have buttons. And that concludes the presentation from the last minutes  from the last meeting. Now uh we are ready for the presentation of the prototype.

Okay , well uh obviously my method for uh s m the marketing of this thing is first to ask the big question , will it sell ? And I think we should show this prototype to people from various age and socio-economic groups and see about any fine tuning that  maybe little things we haven't thought of.

We can't accept every suggestion of course , but maybe we just need to get a few.


We can't accept every suggestion of course , but maybe we just need to get a few.


We can't accept every suggestion of course , but maybe we just need to get a few.

And show the the prototype to consumer research groups , we don't s want somebody to suddenly come to us and tell us that this button is toxic and you know some child will swallow it and then we won't sell any.


And show the the prototype to consumer research groups , we don't s want somebody to suddenly come to us and tell us that this button is toxic and you know some child will swallow it and then we won't sell any.

So we have to get some input from those people.


So we have to get some input from those people.

And then after that we just have to go with our best intuition and you know we like it , we think it's good , we're gonna get behind it and sell it. Um , next slide please. Okay , now the things that I was thinking and th my wish list has really been realised in this prototype. I wanted the shape to be biomorphic , I didn't want anything with angles and all square , I wanted it to be comfy and roundy so we we've got that. The size is small , the colour's bright and warm which is what we wanted. We wanted the feel to be as soft as possible , we'll have the soft buttons

and the way this is shaped , even though it's gonna be hard plastic , it feels good in your hand so that's nice. And functionality I put last on my list because people aren't going to use it before they buy it.

So paradoxically the other features , in other words , the look , the feel um and the shape , that's what people are gonna get in the store.

Um so they'll be our main selling points. So um  th those have been fulfilled by your prototype and go ahead to the next slide please. Okay , so um the shape um I think is a  a one. That's really , really excellent shape. The size is small um and th these points are in the importance for the , for the marketing , these aren't i in how I feel. I think that it's  I think that it's plenty small enough to sell but I think we're sort of right  the scale is one to seven. I think we're sort of right in the middle as far as c other competitors.

And our colour I think is great. The colours are bright and warm and we really do great job there. And given um the constraints that we had I think we got it as soft as possible. And then functionality um I think you did a really good job on functionality , obviously we could have ad added different functions but then we'd disturb something else so I would say that we got to a five out of seven on on functionality.

I mean maximum we have another four point three euros I mean  four thirty.
