Well this is in very interesting
QMSum_135
false
So.
QMSum_135
false
because i it basically has a i it shows very clearly the contrast between , uh , speech recognition research and discourse research because in in discourse and linguistic research , what counts is what 's communit communicative.
QMSum_135
false
Mm - hmm.
QMSum_135
false
And breath , you know , everyone breathes , they breathe all the time. And once in a while breath is communicative , but r very rarely. OK , so now , I had a discussion with Chuck about the data structure
QMSum_135
false
Mm - hmm.
QMSum_135
false
and the idea is that the transcripts will that get stored as a master there 'll be a master transcript which has in it everything that 's needed for both of these uses.
QMSum_135
false
Mm - hmm.
QMSum_135
false
And the one that 's used for speech recognition will be processed via scripts. You know , like , Don 's been writing scripts
QMSum_135
false
Mm - hmm.
QMSum_135
false
and and , uh , to process it for the speech recognition side. Discourse side will have this this side over he the we we 'll have a s ch Sorry , not being very fluent here. But , um , this the discourse side will have a script which will stri strip away the things which are non - communicative. OK. So then the then let 's let 's think about the practicalities of how we get to that master copy with reference to breaths. So what I would r r what I would wonder is would it be possible to encode those automatically ? Could we get a breath detector ?
QMSum_135
false
Oh , just to save the transcribers time.
QMSum_135
false
Well , I mean , you just have no idea. I mean , if you 're getting a breath several times every minute ,
QMSum_135
false
Mm - hmm.
QMSum_135
false
and just simply the keystrokes it takes to negotiate , to put the boundaries in , to to type it in , i it 's just a huge amount of time.
QMSum_135
false
Mm - hmm.
QMSum_135
false
Oops.
QMSum_135
false
Wh - what
QMSum_135
false
Yeah.
QMSum_135
false
And you wanna be sure it 's used , and you wanna be sure it 's done as efficiently as possible , and if it can be done automatically , that would be ideal.
QMSum_135
false
what if you put it in but didn't put the boundaries ?
QMSum_135
false
Well , but
QMSum_135
false
So you just know it 's between these other things ,
QMSum_135
false
Well , OK. So now there 's there 's another another possibility
QMSum_135
false
right ?
QMSum_135
false
which is , um , the time boundaries could mark off words from nonwords. And that would be extremely time - effective , if that 's sufficient.
QMSum_135
false
Yeah I mean I 'm think if it 's too if it 's too hard for us to annotate the breaths per se , we are gonna be building up models for these things and these things are somewhat self - aligning , so if so , we i i if we say there is some kind of a thing which we call a " breath " or a " breath - in " or " breath - out " , the models will learn that sort of thing. Uh , so but you but you do want them to point them at some region where where the breaths really are. So
QMSum_135
false
OK. But that would maybe include a pause as well ,
QMSum_135
false
Well , there 's a there 's
QMSum_135
false
and that wouldn't be a problem to have it , uh , pause plus breath plus laugh plus sneeze ?
QMSum_135
false
Yeah , i You know there is there 's this dynamic tension between between marking absolutely everything , as you know , and and and marking just a little bit and counting on the statistical methods. Basically the more we can mark the better. But if there seems to be a lot of effort for a small amount of reward in some area , and this might be one like this Although I I I 'd be interested to h get get input from Liz and Andreas on this to see if they Cuz they 've - they 've got lots of experience with the breaths in in , uh , uh , their transcripts.
QMSum_135
false
They have lots of experience with breathing ?
QMSum_135
false
Actually Well , yes they do , but we we can handle that without them here. But but but , uh , you were gonna say something about
QMSum_135
false
Yeah , I I think , um , one possible way that we could handle it is that , um , you know , as the transcribers are going through , and if they get a hunk of speech that they 're gonna transcribe , u th they 're gonna transcribe it because there 's words in there or whatnot. If there 's a breath in there , they could transcribe that.
QMSum_135
false
Yeah. Yeah.
QMSum_135
false
That 's what they 've been doing. So , within an overlap segment , they they do this.
QMSum_135
false
Right. But Right. But if there 's a big hunk of speech , let 's say on Morgan 's mike where he 's not talking at all , um , don't don't worry about that.
QMSum_135
false
Yeah.
QMSum_135
false
So what we 're saying is , there 's no guarantee that , um So for the chunks that are transcribed , everything 's transcribed. But outside of those boundaries , there could have been stuff that wasn't transcribed. So you just somebody can't rely on that data and say " that 's perfectly clean data ". Uh do you see what I 'm saying ?
QMSum_135
false
Yeah , you 're saying it 's uncharted territory.
QMSum_135
false
So I would say don't tell them to transcribe anything that 's outside of a grouping of words.
QMSum_135
false
That sounds like a reasonable reasonable compromise.
QMSum_135
false
Yeah , and that 's that that quite co corresponds to the way I I try to train the speech - nonspeech detector , as I really try to not to detect those breaths which are not within a speech chunk but with which are just in in a silence region.
QMSum_135
false
Yeah.
QMSum_135
false
And they so they hopefully won't be marked in in those channel - specific files.
QMSum_135
false
u I I wanted to comment a little more just for clarification about this business about the different purposes.
QMSum_135
false
But
QMSum_135
false
Yeah , so
QMSum_135
false
Mm - hmm.
QMSum_135
false
See , in a in a way this is a really key point , that for speech recognition , uh , research , uh , um , e a it 's not just a minor part. In fact , the I think I would say the core thing that we 're trying to do is to recognize the actual , meaningful components in the midst of other things that are not meaningful. So it 's critical it 's not just incidental it 's critical for us to get these other components that are not meaningful. Because that 's what we 're trying to pull the other out of. That 's our problem. If we had nothing
QMSum_135
false
Yeah.
QMSum_135
false
if we had only linguistically - relevant things if if we only had changes in the spectrum that were associated with words , with different spectral components , and , uh , we we didn't have noise , we didn't have convolutional errors , we didn't have extraneous , uh , behaviors , and so forth , and moving your head and all these sorts of things , then , actually speech recognition i i isn't that bad right now. I mean you can you know it 's it 's the technology 's come along pretty well.
QMSum_135
false
Yeah.
QMSum_135
false
The the the reason we still complain about it is because is when when you have more realistic conditions then then things fall apart.
QMSum_135
false
OK , fair enough. I guess , um , I uh , what I was wondering is what what at what level does the breathing aspect enter into the problem ? Because if it were likely that a PDA would be able to be built which would get rid of the breathing , so it wouldn't even have to be processed at thi at this computational le well , let me see , it 'd have to be computationally processed to get rid of it , but if there were , uh , like likely on the frontier , a good breath extractor then , um , and then you 'd have to
QMSum_135
false
But that 's a research question , you know ? And so
QMSum_135
false
Yeah , well , see and that 's what I wouldn't know.
QMSum_135
false
that And we don't either. I mean so so the thing is it 's it right now it 's just raw d it 's just data that we 're collecting , and so we don't wanna presuppose that people will be able to get rid of particular degradations because that 's actually the research that we 're trying to feed. So , you know , an and maybe maybe in five years it 'll work really well ,
QMSum_135
false
OK.
QMSum_135
false
and and it 'll only mess - up ten percent of the time , but then we would still want to account for that ten percent , so.
QMSum_135
false
I guess there 's another aspect which is that as we 've improved our microphone technique , we have a lot less breath in the in the more recent , uh , recordings , so it 's in a way it 's an artifact that there 's so much on the on the earlier ones.
QMSum_135
false
Uh - huh. I see.
QMSum_135
false
One of the um , just to add to this one of the ways that we will be able to get rid of breath is by having models for them. I mean , that 's what a lot of people do nowadays.
QMSum_135
false
Right.
QMSum_135
false
Right.
QMSum_135
false
Yeah.
QMSum_135
false
And so in order to build the model you need to have some amount of it marked , so that you know where the boundaries are.
QMSum_135
false
Hmm.
QMSum_135
false
Yeah.
QMSum_135
false
So I mean , I don't think we need to worry a lot about breaths that are happening outside of a , you know , conversation. We don't have to go and search for them to to mark them at all , but , I mean , if they 're there while they 're transcribing some hunk of words , I 'd say put them in if possible.
QMSum_135
false
OK , and it 's also the fact that they differ a lot from one channel to the other because of the way the microphone 's adjusted.
QMSum_135
false
Yeah.
QMSum_135
false
Mm - hmm.
QMSum_135
false
OK.
QMSum_135
false
Should we do the digits ?
QMSum_135
false
Yep. OK.
QMSum_135
false
OK.
QMSum_135
false
Mmm. Alright.
QMSum_135
false
Hmm.
QMSum_121
false
Okay. Good morning everybody. Um I'm glad you could all come. I'm really excited to start this team. Um I'm just gonna have a little PowerPoint presentation for us , for our kick-off meeting. My name is Rose Lindgren. I I'll be the Project Manager. Um our agenda today is we are gonna do a little opening and then I'm gonna talk a little bit about the project , then we'll move into acquaintance such as getting to know each other a little bit , including a tool training exercise. And then we'll move into the project plan , do a little discussion and close , since we only have twenty five minutes. First of all our project aim. Um we are creating a new remote control which we have three goals about , it needs to be original , trendy and user-friendly. I'm hoping that we can all work together to achieve all three of those. Um so we're gonna divide us up into three compa three parts. First the functional design which will be uh first we'll do individual work , come into a meeting , the conceptional design , individual work and a meeting , and then the detailed design , individual work and a meeting. So that we'll each be doing our own ideas and then coming together and um collaborating. Okay , we're gonna get to know each other a little bit. So um , what we're gonna do is start off with um let's start off with Amina. Um Alima ,
QMSum_121
false
Alima.
QMSum_121
false
sorry , Alima.
QMSum_121
false
Um we're gonna do a little tool training , so we are gonna work with that whiteboard behind you. Um introduce yourself , um say one thing about yourself and then draw your favourite animal and tell us about it.
QMSum_121
false
Okay. Um I don't know which one of these I have to bring with me.
QMSum_121
false
Probably both.
QMSum_121
false
Right , so , I'm supposed to draw my favourite animal. I have no drawing skills whatsoever. But uh let's see , introduce myself. My name is Alima Bucciantini. Um I'm from the state of Maine in the US. I'm doing nationalism studies , blah , blah , blah , and I have no artistic talents.
QMSum_121
false
How do you spell your name ?
QMSum_121
false
A_ L_ I_ M_ A_.
QMSum_121
false
Thanks.
QMSum_121
false
Oh , and I guess I'm the Industrial Designer on this project. So let's see if I can get
QMSum_121
false
um here. I will draw a little turtle for you all. Not necessarily 'cause it's my absolute favourite animal , but just that I think they're drawable. And you have the pretty little shell going on. Some little eyes. Happy. There you go. That's a turtle.
QMSum_121
false
Yes.
QMSum_121
false
So what are your favourite characteristics ?
QMSum_121
false
Um. I I like the whole having a shell thing.
QMSum_121
false
Mm.
QMSum_121
false
It's quite cool carry your home around where you go , um quite decorative little animals , they can swim , they can , they're very adaptable , they carry everything they need with them , um and they're easy to draw.
QMSum_121
false
Excellent.
QMSum_121
false
Shall we just go around the table ?
QMSum_121
false
Uh Okay. Well , my name is Iain uh
QMSum_121
false
Mm.
