Okay. Yeah. And the battery , is it kind of a rechargeable or it doesn't matter ?

Yeah the um that's the point. The kinetic one is uh y you can recharge uh by the um

Yeah and by  well by just by moving the ar uh your arm the mm well the remote will uh accumulate energy.


Yeah the um that's the point. The kinetic one is uh y you can recharge uh by the um

Yeah and by  well by just by moving the ar uh your arm the mm well the remote will uh accumulate energy.


Yeah and by  well by just by moving the ar uh your arm the mm well the remote will uh accumulate energy.

But I d I don't know it's  if it is feasible because I don't know if yet if if the user will move enough to provide the remote um all the necessary energy.


Yeah and by  well by just by moving the ar uh your arm the mm well the remote will uh accumulate energy.

But I d I don't know it's  if it is feasible because I don't know if yet if if the user will move enough to provide the remote um all the necessary energy.

Mm.  Mm. Okay. Yeah. Yeah. We we might check with our R_ and D_ department to see if they have this product  ready for market.

Mm.  Mm. Okay. Yeah. Yeah. We we might check with our R_ and D_ department to see if they have this product  ready for market.

Yeah.  And  yeah and so can you go to the next slide please. So and uh that's uh that summarize well what I have said.


Mm.  Mm. Okay. Yeah. Yeah. We we might check with our R_ and D_ department to see if they have this product  ready for market.

Yeah.  And  yeah and so can you go to the next slide please. So and uh that's uh that summarize well what I have said.

So uh you're right we can uh see in our uh R_ and D_ uh  if the kinetic metal is sufficient to provide enough energy.

So the titanium case is the normal case that  I'll show you some pictures that I have and you tell me whether they are titanium case or not.

'Cause I am not very sure , plastic , titanium or whatever. There's another point I want to make , is that the uh  well you've seen them I le na my presentation that um I point out some  why buttons are not the mm not the only ways you can  use  Yeah. Yeah , maybe n

Yeah.  So the user interface is uh i it uses the aspect uh of a computer system , a programme which can be seen or heard or otherwise perceived by the human user


Yeah.  So the user interface is uh i it uses the aspect uh of a computer system , a programme which can be seen or heard or otherwise perceived by the human user

and the commands and mechanism the user uses to control its operation and input data. So you s this gives you the ways to input data and we have uh  we are more  we emphasise more on the graphical user interface here. The idea is to represent buttons as figures , diagrams , symbols and on so you you can easily when you look at the symbols you understand what it is doing.

The next one. Mm so somebody  some people use uh some people use a spinning wheel th with the L_C_ display so instead of using the mm buttons you have a L_C_D_ screen and then there you can u you can use that as buttons , you can use that as real  so so that could be an option as well. Touch screen , I mean.

Next one. And some people propose a scroll button. Integrated with push buttons or you may have scroll button instead of p just the push button. Like the one we have here. Uh , next one. So mm


Next one. And some people propose a scroll button. Integrated with push buttons or you may have scroll button instead of p just the push button. Like the one we have here. Uh , next one. So mm

so there are a few aspects that I collected here. So s basically this deals with special users , children , handicapped people , old people , and uh mm and prog basically they are programmable , specially for children. And uh mm  yeah yeah. And then they also secure uh covers , to protect uh secure and hidden programming and battery covers that will protect your settings. So  But we don't have to integrate all these complicated features. I'm just saying that the  currently in the market there are there are control there are remote controllers f  customisable for different people. Yeah , so that's the point. The next one. And uh you see this is the one where you have the protection cover. Mm maybe useful for children , they migh you you they only see the buttons outside. And for adults wh where you have more control you can see the one inside. So the adults might wanna have a key to lock that to pr so children will not touch the button inside.

So this guy  this is another company that provides big buttons. At  I see that that is useful for old people and then you don't get it lost. But for our product we don't need a big one because you have voice recognition e eventually with use.

Yeah but uh as Norman say if uh there is uh already a commercial product available who t who do this we we can check uh to integrate it i into our uh new remote control.

Yeah. Yeah. Yeah. Yeah. And uh , this is another one where you can uh  the the the part that's a V_ standing for the volume. So there's a up arrow and a down arrow. But you the see that in the V_ , the V_ appears to be the down arrow on the top  on the top up arrow   if you

And here are  is uh here is a s short summary that I summary that I compiled after the findings I found. Big buttons are convenient , voice recognition helps , push buttons , scroll buttons , spinning wheels can be used as navigation tools. And uh user customisable is important and finally simplicity simplicity is the key. Yeah. So  we have many concepts there

Well I  I think you it's it's it's fine you have uh reviewed all all the possibilities

but uh uh well uh i if we consider that uh the user interface is displayed on the T_V_ screen I don't think we nee uh we need much buttons in the remote


but uh uh well uh i if we consider that uh the user interface is displayed on the T_V_ screen I don't think we nee uh we need much buttons in the remote

since we we just have to navigate and to have a okay or enter key or things like that ,


since we we just have to navigate and to have a okay or enter key or things like that ,

because uh adding wheels or scrolls uh makes the thing more complicated and more expensive also , so.


because uh adding wheels or scrolls uh makes the thing more complicated and more expensive also , so.

Or maybe we can include the user manual in the in the remote control  and we should have just a button like help and you say uh and you ik you press the button help and maybe you see the the user m might in the in the T_V_.

Can be used by both kids and old people.

Mm.  Well uh what I s propose is that uh you know a remote controller , i  it could be a cube ,

is uh a small device that uh looks like a cube and maybe you can just change the  um the buttons , if you ch turn one side you get one one buttons , you turn the other side you get the other buttons , so for maybe new generation people who get used to the computer they want lots of controls.

And then we can decide what what we can  yeah.


And then we can decide what what we can  yeah.

So we just made an marketing survey of what people need from our remotes and how it could be special from the other remotes. And we got the best on the responses from the questionnaires. Uh we also have some prizes for the most creative solutions. And we found the following solutions which we could  which would be helpful for our design. So seventy percent of the users , they find their remote controls very ugly , they don't find it pleasant to use in the size or usage or anything. And eighty percent of the people they are always l I mean they are willing to spend more money if the remote control would look fancy. And the current remote controls do not match well the operating behaviour of the user. And seventy five percent of the users said they zap a lot.

so the rest of the ninety percent of the buttons they're not used most of the times.


so the rest of the ninety percent of the buttons they're not used most of the times.


so the rest of the ninety percent of the buttons they're not used most of the times.

So this were the findings which we found. And also they cited frustrations with the present remote controls. Most of  fifty percent of the time the remote controls are lost somewhere in the room and people are always searching for them  rather than watching the T_V_.


So this were the findings which we found. And also they cited frustrations with the present remote controls. Most of  fifty percent of the time the remote controls are lost somewhere in the room and people are always searching for them  rather than watching the T_V_.

And by the time they found the remote control the program is finished.


And by the time they found the remote control the program is finished.

And um if the remote control is too complicated it takes much time to learn the functionality of it.


And um if the remote control is too complicated it takes much time to learn the functionality of it.


And um if the remote control is too complicated it takes much time to learn the functionality of it.

So you can just see the percentage , fifty percent people they responded that they always lose their remotes and thirty four percent they say that it's quite difficult to learn if it's too complex.

So you can just see the percentage , fifty percent people they responded that they always lose their remotes and thirty four percent they say that it's quite difficult to learn if it's too complex.

So keeping in view all these findings and the frustrations I think this should be the solution for them. We should have an L_C_D_ on the rem remote control.


So keeping in view all these findings and the frustrations I think this should be the solution for them. We should have an L_C_D_ on the rem remote control.

Well mm w well I I I don't really see the advantage of having uh L_C_D_ on the on the remote control if we have a a a big screen and uh display on the screen.


Well mm w well I I I don't really see the advantage of having uh L_C_D_ on the on the remote control if we have a a a big screen and uh display on the screen.


yeah of course it's fancy trendy and so on but it's it's expensive to produce  and it's not really


yeah of course it's fancy trendy and so on but it's it's expensive to produce  and it's not really

I mean as our survey says that people are willing to pay more if their remotes are fancy.


yeah of course it's fancy trendy and so on but it's it's expensive to produce  and it's not really

I mean as our survey says that people are willing to pay more if their remotes are fancy.

So if we have a L_C_D_ on the remote , rather than looking onto the T_V_ you just look into a remote and navigate it. It's the same menu as we have saw that iPod remote control.


I mean as our survey says that people are willing to pay more if their remotes are fancy.

Yeah but when you play with the iPod you don't have  a big screen in front of you , s


Yeah but when you play with the iPod you don't have  a big screen in front of you , s

You can use this screen instead of the big se screen ,


You can use this screen instead of the big se screen ,


If you re-use the existing screen , we element  eliminate the L_C_D_ , after all the L_C_D_ just to display


If you re-use the existing screen , we element  eliminate the L_C_D_ , after all the L_C_D_ just to display

and if you have the colourful screen you can make the display colourful , fancy , as fancy as the one on the L_C_D_ ,


and if you have the colourful screen you can make the display colourful , fancy , as fancy as the one on the L_C_D_ ,


I mean this were the points which we got from the market demands.


So I th I I  well I think we we can focus on the uh on the fancy look on the uh


So I th I I  well I think we we can focus on the uh on the fancy look on the uh

on the speech recognition if the technology is available

Mm. Remember we have a s budget for the cost of producing the remote controller.


Mm. Remember we have a s budget for the cost of producing the remote controller.


so the thing is you can find out how much an L_C_D_ will cost and then we'll decide again.


so the thing is you can find out how much an L_C_D_ will cost and then we'll decide again.

I mean that should be found out by the Industrial Designers.

Yeah I I I think that uh well uh as we have seen in the in the presentation uh well uh about uh uh fifty percent of the of the percent n choose the button


Yeah I I I think that uh well uh as we have seen in the in the presentation uh well uh about uh uh fifty percent of the of the percent n choose the button

so uh I think to have uh five uh simple button is sufficient for our functionality.


so uh I think to have uh five uh simple button is sufficient for our functionality.

It doesn't mean that the other buttons are not necessary or important.


It doesn't mean that the other buttons are not necessary or important.


But the uh the thing is is i is that we can add a functionality on the on the T_V_ screen


and then you choose with the with the button to  well you navigate


and then you choose with the with the button to  well you navigate

Yeah , yeah. So so the at most  more power uh.


and then you choose with the with the button to  well you navigate

Yeah , yeah. So so the at most  more power uh.

Or maybe we can u uh or maybe we can uh make this the ten percent of button more bigger than the others.

Or it could be like this , as the people say , if they have a L_C_D_ on the remote not on the television. Because when you have the L_C_D_ onto the television screen you miss the picture in the background , we are most focused on the commands.

So if you have then L_C_D_ in the remote , you just have a menu , and increasing and lower these signs here to change the programs and this menu when you press the menu , in the L_C_D_ displays as you go on pressing the menu it faster displays volume , then the program , then the brightness , contrast and all the stuff.

I think that there's no contradiction here , because if there are few buttons , you don't have to look at your your controller any more because you know where the buttons are , so if you wanna control the screen d sh sharpness you just say sharpness

uh it's always boring to change the batteries of the remotes control ,


uh it's always boring to change the batteries of the remotes control ,

so we have some one charger there and whenever we don't use the remote control we put it in the charger.


so we have some one charger there and whenever we don't use the remote control we put it in the charger.


And when we're using that t remote and if we misplace somewhere , in the charger we have a small button , and just by pressing the button in the charger the uh remote control beeps , wherever it is.


And when we're using that t remote and if we misplace somewhere , in the charger we have a small button , and just by pressing the button in the charger the uh remote control beeps , wherever it is.

Yeah. And that's a good idea , that's simple , like in phones.


Yeah. And that's a good idea , that's simple , like in phones.


Yeah. And that's a good idea , that's simple , like in phones.

I mean it doe it also doesn't require a voice command ,


I mean it doe it also doesn't require a voice command ,

But you don't you don't have to move the the charger.


I mean it doe it also doesn't require a voice command ,

But you don't you don't have to move the the charger.

because there are problems with a voice command.

Yeah if there if there uh there is nuff not enough battery. Also and uh uh the remote is lost.


Yeah if there if there uh there is nuff not enough battery. Also and uh uh the remote is lost.


That  we can  what we can do is we can program a function whereby when you press the switch off T_V_ button , the off button , the remote there be s uh instruction on the screen , please charge charge me. You never get it lost


That  we can  what we can do is we can program a function whereby when you press the switch off T_V_ button , the off button , the remote there be s uh instruction on the screen , please charge charge me. You never get it lost

because uh every time you're off the computer   the T_V_ you are asked the the command the T_V_ com remote controller would tell you to put it back to where  to the charger.


because uh every time you're off the computer   the T_V_ you are asked the the command the T_V_ com remote controller would tell you to put it back to where  to the charger.

Yeah. So you will never get lost   yeah.

I mean mm very big or something with lot of buttons.


Well the last one with the um  yeah with the two parts was uh  original , so


Well the last one with the um  yeah with the two parts was uh  original , so

I mean  uh I mean uh I mean uh you see if it's like that even a kid who wants to have a control he could just plug it and  use it , you can't avoid him.


I mean  uh I mean uh I mean uh you see if it's like that even a kid who wants to have a control he could just plug it and  use it , you can't avoid him.

But you can have an button for child lock.

So just by pressing the button with some code , you t you put a lock onto the remote , so that he can't use even


So just by pressing the button with some code , you t you put a lock onto the remote , so that he can't use even

Well we can think about uh having uh on the on the on the user interface when you switch on the T_V_ you can uh well write a code or choose a category , if it is kids , uh things like that.


Well we can think about uh having uh on the on the on the user interface when you switch on the T_V_ you can uh well write a code or choose a category , if it is kids , uh things like that.


Or maybe you have to to show some specific programmes for kids and then just just  yeah just push uh kids button so it's automatically

I think these other four points they're the market demands and so it's for the user interface design and industrial design to just think


I think these other four points they're the market demands and so it's for the user interface design and industrial design to just think


yeah. So for my part I will check the prices the um the prices difference uh of what to use , where to use , and s uh and so on.


yeah. So for my part I will check the prices the um the prices difference uh of what to use , where to use , and s uh and so on.

Yeah I think it should be clearer for us in the next meeting that th uh these  could be included.

Mm.  I think we need to define also a s the set of vocabularies for the speech recogniser


Mm.  I think we need to define also a s the set of vocabularies for the speech recogniser

because uh if you want  uh say we can sort by channels or sort by T_V_ programs , you have to decide a category of vocabularies for them. If numbers , they're easy ,

No , we have a problem there. You see uh if you have a voice commands and you are s you are watching a score on uh  basketball score or something , and if the score comes twenty four thirty five , you've just say twenty five


No , we have a problem there. You see uh if you have a voice commands and you are s you are watching a score on uh  basketball score or something , and if the score comes twenty four thirty five , you've just say twenty five


No , we have a problem there. You see uh if you have a voice commands and you are s you are watching a score on uh  basketball score or something , and if the score comes twenty four thirty five , you've just say twenty five

and suddenly  the screen the channel goes to twenty five.

So I think there should be a prefix to some numbers

Well but well e every possible word uh has a probability to come about of the T_V_ so.


So I think there should be a prefix to some numbers

Well but well e every possible word uh has a probability to come about of the T_V_ so.

I mean the the  you just check all the probability that saying T_V_ twenty five and just ordinary twenty five.

I mean the the  you just check all the probability that saying T_V_ twenty five and just ordinary twenty five.


I mean the the  you just check all the probability that saying T_V_ twenty five and just ordinary twenty five.

Ordinary twenty five you almost there's a probability of being said around sixty seventy percent


Ordinary twenty five you almost there's a probability of being said around sixty seventy percent


Ordinary twenty five you almost there's a probability of being said around sixty seventy percent

and T_V_ twenty five I dunno it will be round about one or two percent.


and T_V_ twenty five I dunno it will be round about one or two percent.


So it's better to have some prefix  before the number.


So it's better to have some prefix  before the number.

But I I I think that the user would like wou would like to associate the channel or call the channel rather than than the numbers.


So it's better to have some prefix  before the number.

A and in the same lines we would have a  one more problem. If we are using the television in the different environments , say in the factories or in the shops where there is a lot of noise and this voice commands if they fail to work , that would bring a bad name  bad uh reputation for our company.

Yeah. So. Um. Yeah , it 's  it 's interesting. I mean , basically we 're dealing with rever reverberation , and , um , when we deal with pure reverberation , the technique he 's using works really , really well.

You mean , from the actual , uh , recordings ?

Yeah. Yeah. Um  And actually it brought up a question which may be relevant to the Aurora stuff too. Um , I know that when you figured out the filters that we 're using for the Mel scale , there was some experimentation that went on at  at , uh  at OGI. Um , but one of the differences that we found between the two systems that we were using ,  the  the Aurora HTK system baseline system  and the system that we were  the  the uh , other system we were using , the uh , the SRI system , was that the SRI system had maybe a , um , hundred hertz high - pass. And the , uh , Aurora HTK , it was like twenty.

So the , uh , center would be somewhere around like hundred

and  hundred and  hundred  hundred and  maybe  it 's like  fi hundred hertz.

But do you know , for instance , h how far down it would be at twenty hertz ? What the  how much rejection would there be at twenty hertz , let 's say ?

But do you know , for instance , h how far down it would be at twenty hertz ? What the  how much rejection would there be at twenty hertz , let 's say ?

Yeah , any idea what the curve looks like ?


But do you know , for instance , h how far down it would be at twenty hertz ? What the  how much rejection would there be at twenty hertz , let 's say ?

Yeah , any idea what the curve looks like ?

Twenty hertz frequency  Oh , it 's  it 's zero at twenty hertz , right ? The filter ?


Yeah , any idea what the curve looks like ?

Twenty hertz frequency  Oh , it 's  it 's zero at twenty hertz , right ? The filter ?

Yea - actually , the left edge of the first filter is at sixty - four.


Twenty hertz frequency  Oh , it 's  it 's zero at twenty hertz , right ? The filter ?

Yea - actually , the left edge of the first filter is at sixty - four.


Yea - actually , the left edge of the first filter is at sixty - four.

So anything less than sixty - four is zero.


So anything less than sixty - four is zero.


So anything less than sixty - four is zero.

It 's actually set to zero ? What kind of filter is that ?


It 's actually set to zero ? What kind of filter is that ?


It  This is the filter bank in the frequency domain that starts at sixty - four.


It  This is the filter bank in the frequency domain that starts at sixty - four.

Oh , so you , uh  so you really set it to zero , the FFT ?


Oh , so you , uh  so you really set it to zero , the FFT ?

yeah. So it 's  it 's a weight on the ball spectrum. Triangular weighting.


yeah. So it 's  it 's a weight on the ball spectrum. Triangular weighting.

Right. OK. Um  OK. So that 's  that 's a little different than Dave thought , I think. But  but , um , still , it 's possible that we 're getting in some more noise. So I wonder , is it  @ @ Was there  their experimentation with , uh , say , throwing away that filter or something ? And , uh


Right. OK. Um  OK. So that 's  that 's a little different than Dave thought , I think. But  but , um , still , it 's possible that we 're getting in some more noise. So I wonder , is it  @ @ Was there  their experimentation with , uh , say , throwing away that filter or something ? And , uh

Um , yeah , we  we 've tried including the full  full bank. Right ? From zero to four K.


Um , yeah , we  we 've tried including the full  full bank. Right ? From zero to four K.


Um , yeah , we  we 've tried including the full  full bank. Right ? From zero to four K.

And that 's always worse than using sixty - four hertz.


Um , yeah , we  we 've tried including the full  full bank. Right ? From zero to four K.

And that 's always worse than using sixty - four hertz.

Right , but the question is , whether sixty - four hertz is  is , uh , too , uh , low.


And that 's always worse than using sixty - four hertz.

Right , but the question is , whether sixty - four hertz is  is , uh , too , uh , low.

Yeah , I mean , make it a hundred or so ?


Right , but the question is , whether sixty - four hertz is  is , uh , too , uh , low.

Yeah , I mean , make it a hundred or so ?

I t I think I 've tried a hundred and it was more or less the same , or slightly worse.

Mmm. That 'd be something to look at sometime because what , um , eh , he was looking at was performance in this room.


No , no , no. I think I just tried it on SpeechDat - Car.

Would that be more like  Well , you 'd think that 'd be more like SpeechDat - Car , I guess , in terms of the noise. The SpeechDat - Car is more , uh , sort of roughly stationary , a lot of it. And  and TI - digits maybe is not so much as


Mmm. That 'd be something to look at sometime because what , um , eh , he was looking at was performance in this room.

Mm - hmm. OK. Well , maybe it 's not a big deal. But , um  Anyway , that was just something we wondered about. But , um , uh , certainly a lot of the noise , uh , is , uh , below a hundred hertz. Uh , the signal - to - noise ratio , you know , looks a fair amount better if you  if you high - pass filter it from this room.

Uh , the signal - to - noise ratio , you know , looks a fair amount better if you  if you high - pass filter it from this room.

But , um  but it 's still pretty noisy. Even  even for a hundred hertz up , it 's  it 's still fairly noisy. The signal - to - noise ratio is  is  is actually still pretty bad.

Well , we got a  a video projector in here , uh , and , uh  which we keep on during every  every session we record ,

But  but , uh  So , those are  those are major components , I think ,


Um , but , um , it , uh  I guess , I  maybe I said this last week too but it  it  it really became apparent to us that we need to  to take account of noise. And , uh , so I think when  when he gets done with his prelim study I think  one of the next things we 'd want to do is to take this , uh  uh , noise , uh , processing stuff and  and , uh  uh , synthesize some speech from it.

And then  Um , I think in about , um , a little less than two weeks.


And then  Um , I think in about , um , a little less than two weeks.

Yeah. Yeah. So. Uh , it might even be sooner. Uh , let 's see , this is the sixteenth , seventeenth ? Yeah , I don't know if he 's before  It might even be in a week.


Yeah. Yeah. So. Uh , it might even be sooner. Uh , let 's see , this is the sixteenth , seventeenth ? Yeah , I don't know if he 's before  It might even be in a week.

Huh. I  I guessed that they were gonna do it some time during the semester

They seem to be  Well , the semester actually is starting up.

Yeah , the semester 's late  late August they start here.


Yeah , the semester 's late  late August they start here.

So they do it right at the beginning of the semester.


So they do it right at the beginning of the semester.

Yeah. So , uh  Yep. I mean , that  that was sort of one  I mean , the overall results seemed to be first place in  in  in the case of either , um , artificial reverberation or a modest sized training set. Uh , either way , uh , i uh , it helped a lot. And  But if you had a  a really big training set , a recognizer , uh , system that was capable of taking advantage of a really large training set  I thought that  One thing with the HTK is that is has the  as we 're using  the configuration we 're using is w s is  being bound by the terms of Aurora , we have all those parameters just set as they are. So even if we had a hundred times as much data , we wouldn't go out to , you know , ten or t or a hundred times as many Gaussians or anything. So , um , it 's kind of hard to take advantage of  of  of big chunks of data. Uh , whereas the other one does sort of expand as you have more training data.

It does it automatically , actually. And so , um , uh , that one really benefited from the larger set. And it was also a diverse set with different noises and so forth. Uh , so , um , that , uh  that seemed to be  So , if you have that  that better recognizer that can  that can build up more parameters , and if you , um , have the natural room , which in this case has a p a pretty bad signal - to - noise ratio , then in that case , um , the right thing to do is just do  u use speaker adaptation. And  and not bother with  with this acoustic , uh , processing. But I think that that would not be true if we did some explicit noise - processing as well as , uh , the convolutional kind of things we were doing.

but , uh , I noticed , just glancing at the , uh , Hopkins workshop , uh , web site that , uh , um  one of the thing I don't know  Well , we 'll see how much they accomplish , but one of the things that they were trying to do in the graphical models thing was to put together a  a , uh , tool kit for doing , uh r um , arbitrary graphical models for , uh , speech recognition.


Oh. Uh , he  he , uh  he was here for a couple years


Oh. Uh , he  he , uh  he was here for a couple years

Uh , so he did  he did his PHD on dynamic Bayes - nets , uh , for  for speech recognition. He had some continuity built into the model , presumably to handle some , um , inertia in the  in the production system , and , um


Um , I 've been playing with , first , the , um , VAD. Um ,  so it 's exactly the same approach , but the features that the VAD neural network use are , uh , MFCC after noise compensation. Oh , I think I have the results.


Yeah , it was actually  No. Not  I mean , it was just the noisy features I guess.


Um  This is what we get after  This  So , actually , we , yeah , here the features are noise compensated and there is also the LDA filter. Um , and then it 's a pretty small neural network which use , um ,  nine frames of  of six features from C - zero to C - fives , plus the first derivatives. And it has one hundred hidden units.

Um  So it 's  it 's not bad , but the problem is still that the latency is too large.


Um  So it 's  it 's not bad , but the problem is still that the latency is too large.

Because  um  the  the latency of the VAD is two hundred and twenty milliseconds. And , uh , the VAD is used uh , i for on - line normalization , and it 's used before the delta computation. So if you add these components it goes t to a hundred and seventy , right ?

If  Yeah , if you add the c delta comp delta computation

If  Yeah , if you add the c delta comp delta computation

So it 's two - twenty. I the is this  are these twenty - millisecond frames ? Is that why ? Is it after downsampling ? or


So it 's two - twenty. I the is this  are these twenty - millisecond frames ? Is that why ? Is it after downsampling ? or

The two - twenty is one hundred milliseconds for the um  No , it 's forty milliseconds for t for the , uh , uh , cleaning of the speech. Um  then there is , um , the neural network which use nine frames. So it adds forty milliseconds.

Mmm. Forty  This forty plus twenty , plus one hundred.


Yeah , there are twenty that comes from  There is ten that comes from the LDA filters also. Right ?


Yeah , there are twenty that comes from  There is ten that comes from the LDA filters also. Right ?

Uh , so it 's two hundred and ten , yeah.


Uh , so it 's two hundred and ten , yeah.


If you are phrasing f  using three frames , it is thirty here for delta.

OK. And then there 's delta besides that ?

So this is the features that are used by our network and then afterwards , you have to compute the delta on the , uh , main feature stream ,

which is um , delta and double - deltas , which is fifty milliseconds.

Yeah. No , I mean , the  after the noise part , the forty  the  the other hundred and eighty  Well , I mean , Wait a minute. Some of this is , uh  is , uh  is in parallel , isn't it ? I mean , the LDA  Oh , you have the LDA as part of the V D - uh , VAD ? Or

Ah. So in that case there isn't too much in parallel. Uh


Ah. So in that case there isn't too much in parallel. Uh

No. There is , um , just downsampling , upsampling , and the LDA.


Ah. So in that case there isn't too much in parallel. Uh

No. There is , um , just downsampling , upsampling , and the LDA.

Um , so the delta at the end is how much ?


No. There is , um , just downsampling , upsampling , and the LDA.

Um , so the delta at the end is how much ?


But well , we could probably put the delta , um ,  before on - line normalization. It should not that make a big difference ,

What if you used a smaller window for the delta ?


But well , we could probably put the delta , um ,  before on - line normalization. It should not that make a big difference ,

What if you used a smaller window for the delta ?

Could that help a little bit ? I mean , I guess there 's a lot of things you could do to

Yeah. So if you  if you put the delta before the , uh , ana on - line  If  Yeah


And then y then you don't have that additive


And then y then you don't have that additive

cuz the time constant of the on - line normalization is pretty long compared to the delta window ,

OK. And you ought to be able to shove tw , uh  sh uh  pull off twenty milliseconds from somewhere else to get it under two hundred , right ? I mean


OK. And you ought to be able to shove tw , uh  sh uh  pull off twenty milliseconds from somewhere else to get it under two hundred , right ? I mean


mill a hundred milliseconds for smoothing is sort of an arbitrary amount. It could be eighty and  and probably do @ @


uh  Wh - what 's the baseline you need to be under ? Two hundred ?


uh  Wh - what 's the baseline you need to be under ? Two hundred ?

Well , we don't know. They 're still arguing about it.


uh  Wh - what 's the baseline you need to be under ? Two hundred ?

Well , we don't know. They 're still arguing about it.

I mean , if it 's two  if  if it 's , uh  if it 's two - fifty , then we could keep the delta where it is if we shaved off twenty. If it 's two hundred , if we shaved off twenty , we could  we could , uh , meet it by moving the delta back.

So , how do you know that what you have is too much if they 're still deciding ?
