B: OK , I s I see .
A: Yeah , in another way ,
A: yeah .
A: Yeah .
B: Yeah .
B: I see .
F: Yeah , Dave Dave uh is , um , also gonna be doin usin playing around with echo cancellation for the nearfield farfield stuff ,
G: So .
F: so we 'll be G: And I guess Espen ?
G: This is uh is he here too ?
G: May also be working F: Yeah .
G: So it would just be ver
G: that 's really the next step
G: because we can't do too much , you know , on term in terms of recognition results knowing that this is a big problem
B: Mm - hmm .
G: um , until we can do that kind of processing .
G: And so , once we have some some of yours ,
A: OK .
A: Yeah I 'm working on it .
G: and @ @ we 'll move on .
B: I think this also ties into one of the things that Jane is gonna talk about too .
D: Um ,
G: OK .
E: Mm - hmm . Mm - hmm .
D: I also wanted to say I have done all this chopping up of digits ,
D: so I have some naming conventions that we should try to agree on .
G: Oh right .
D: So let 's do that off - line ,
D: we don't need to do it during the meeting .
G: Yeah .
G: Right .
C: OK .
G: Definitely G: Uh , and Don should D: And and I have scripts that will extract it out from " key " files
D: and and do all the naming automatically ,
G: OK .
D: so you don't have to do it by hand .
C: Alright .
G: Great .
G: So that that 's it for the C: You 've compiled the list of , uh , speaker names ?
G: Speakers and D: Mm - hmm .
G: OK .
C: Not names ,
C: but I Ds .
D: Yep .
D: Yeah , names names in the names to I Ds ,
D: so you
C: OK .
G: Great .
D: and it does all sorts of matches
D: because the way people filled out names is different on every single file
D: so it does a very fuzzy sort of match .
G: Right .
C: Cool .
G: So at this point we can sort of finalize the naming , and so forth ,
D: Yep .
G: and we 're gonna basically re rewrite out these waveforms that we did
C: Mm - hmm .
G: because as you notice in the paper your " M O
G: in one meeting
G: and " M O - two " in another meeting and it 's we just need to standardize the
C: Yeah .
C: That was my fault .
G: um ,
G: no it 's it 's F: No , I didn't notice that actually .
G: um , that 's why those comments are s are in there .
C: Yeah .
D: Yep .
C: Then disregard it then .
D: So th I now have a script that you can just say basically look up Morgan ,
G: So G: Right .
F: Yeah .
G: OK .
D: and it will give you his ID .
G: Great , great .
C: OK .
D: So .
G: Terrific .
D: Um ,
D: alright .
D: Do we D: Don , you had disk space and storage formats .
D: Is that something we need to talk about at the meeting ,
D: or should you just talk with Chuck at some other time ?
C: Um , I had some general questions just about the compression algorithms of shortening waveforms
C: and I don't know exactly who to ask .
C: I thought that maybe you would be the the person to talk to .
C: So , is it a lossless compression <comment> when you compress ,
D: Mm - hmm .
C: so D: Entropy coding .
C: It just uses entropy coding ?
D: So .
C: OK .
C: So , I mean , I guess my question would be is
C: I just got this new eighteen gig drive installed .
C: Um , yeah ,
C: which is D: And I assume half of it is scratch and half of it is ?
C: I 'm not exactly sure how they partitioned it .
D: Probably , yeah .
C: But um ,
F: That 's typical , huh .
C: yeah , I don't know what 's typical here ,
C: but um ,
C: it 's local though ,
C: so D: That doesn't matter .
C: But D: You can access it from anywhere in ICSI . N C: OK .
F: In fact , this is an eighteen gig drive , <comment> or is it a thirty six gig drive with eighteen C: Alright .
C: How do you do that ?
D: N C: Eighteen .
G: Eigh - eighteen .
G: It was a spare that Dave had around F: Oh OK .
D: Slash N slash machine name , slash X A in all likelihood .
C: Oh I see .
C: OK .
C: Alright , I did know that .
D: Um , so the the only question is how much of it D: The distinction between scratch and non - scratch is whether it 's backed up or not .
C: Mm - hmm .
C: Right .
D: So what you wanna do is use the scratch for stuff that you can regenerate .
C: OK .
D: So ,
D: the stuff that isn't backed up is not a big deal
D: because disks don't crash very frequently ,
C: Right .
D: as long as you can regenerate it .
C: Right .
G: Yeah it 's C: I mean all of this stuff can be regenerated ,
C: it 's just a question G: Well the D: Then put it all on scratch
D: because we 're ICSI is is bottlenecked by backup .
G: Yeah .
E: Mm - hmm , very good point .
C: OK .
G: Well I 'd leave all the All the transcript stuff shouldn't should be backed up ,
D: So we wanna put E: Mm - hmm .
G: but all the waveform <comment> Sound files should not be backed up ,
C: Yeah , I guess C: Right .
G: the ones that you write out .
C: OK .
C: So , I mean , I guess th the other question was then , should we shorten them , downsample them , or keep them in their original form ?
C: Um D: It just depends on your tools .
D: I mean , because it 's not backed up and it 's just on scratch , if your sc tools can't take shortened format , I would leave them expanded ,
C: Right .
D: so you don't have to unshorten them every single time you wanna do anything .
C: OK .
G: We can downsample them ,
C: Do you think that 'd be OK ?
G: so .
G: Yeah .
C: To downsample them ?
G: Yeah , we get the same performance .
C: OK .
G: I mean the r the front - end on the SRI recognizer just downsamples them on the fly ,
C: Yeah , I guess the only argument against downsampling is to preserve just the original files in case we want to experiment with different filtering techniques .
G: so G: So that 's F: I I I 'm sorry G: Yeah , if
F: Yeah , l I mean over all our data , we we want to not downsample .
G: fe
G: You 'd you wanna not .
G: OK .
G: So we 're what we 're doing is we 're writing out F: Yeah .
G: I mean , this is just a question .
G: We 're writing out these individual segments , that wherever there 's a time boundary from Thilo , or or Jane 's transcribers , you know , we we chop it there .
F: Yeah .
F: Mm - hmm .
G: And the reason is so that we can feed it to the recognizer ,
F: Mm - hmm .
G: and throw out ones that we 're not using and so forth .
F: Yeah .
G: And those are the ones that we 're storing .
D: Yeah , as I said , since that 's it 's regeneratable , what I would do is take downsample it ,
G: So G: Yeah .
D: and compress it however you 're e the SRI recognizer wants to take it in .
G: Yeah .
G: So we can't shorten them ,
F: ye
G: but we can downsample them .
C: Right .
F: Yeah , I mean F: yeah , I 'm sorry .
G: So .
F: As yeah , as long as there is a a form that we can come from again , that is not downsampled , <comment> then ,
C: r
C: Yeah .
G: Oh yeah th
C: Yeah those are gonna be kept .
G: Yeah . Yeah .
G: That that 's why we need more disk space
F: uuu
G: cuz we 're basically duplicating the originals , um F: Yeah .
F: Then it 's fine .
D: Right .
F: But for for fu future research we 'll be doing it with different microphone positions and so on
G: Oh yeah .
G: No . We always have the original long ones .
D: Yep .
C: Right .
F: we would like to F: Yeah .
B: So the SRI front - end won't take a uh an an a large audio file name and then a a list of segments to chop out <comment> from that large audio file ?
B: They actually have to be chopped out already ?
G: Um , it 's better if they 're chopped out ,
G: and and it it will be B: Uh - huh .
G: yeah , y we could probably write something to do that ,
G: but it 's actually convenient to have them chopped out
G: cuz you can run them , you know , in different orders .
G: You c you can actually move them around .
D: And that 's the whole point about the naming conventions
G: Uh , you can get rid of
D: is that you could run all the English speaking ,
G: Yeah , it it 's a lot faster .
D: all the native speakers ,
G: Right . You can grab everything with the word " the " in it ,
D: and all the non - native speakers ,
D: and all the men , and all the women .
G: and it 's D: Yeah .
G: That 's a lot quicker than actually trying to access the wavefile each time ,
G: find the time boundaries and G: So in principle , yeah , you could do that ,
B: I don't I don't think that 's really right .
G: but it 's G: but it 's um D: " That 's just not right , man . "
