    1. 1. Introduction to CHILDES and TalkBank Brian MacWhinneyCMU - Psychology, Modern Languages, Language Technologies Institute
    2. 2. The goal of TalkBank
    3. 3. The core ideaHuman communication is a single unifiedprocess.However, patterns in communication areanalyzed by 20 different fields.The time scales of the processes varies frommilliseconds to centuries.But all of these processes must have theirultimate effect in the Moment.We can capture the Moment on video.
    4. 4. PrinciplesData-sharing, Informed ConsentMultimediaOpen Access, Web Access,CommentarySpecified FormatInteroperabilityCommunity integration
    5. 5. Availabilityhttp://childes.psy.cmu.eduhttp://talkbank.orgprograms, manuals, fonts, morphologies, CAconventions, video production guides, XMLSchema, links to other programsdata can be either downloaded or playedback over the web
    6. 6. Current target areas1. CHILDES2. PhonBank3. BilingualBank4. AphasiaBank5. CABank6. ClassBank
    7. 7. CHILDESChild Language Data Exchange SystemFounded in 1984 in Concord MADirector: Brian MacWhinney macw@cmu.eduProgrammers: Leonid Spektor, Franklin Chen3000 Members130 corporaOver 3200 published articles
    8. 8. CHILDES and TalkBank CHILDES TalkBankAge 23 years 7 yearsWords 44 million 8 + 55 millionMedia 750 GB 450GBLanguages 32 18Publications 3200+ 89Users 3000+ 500
    9. 9. Practical Considerations Learning CLAN takes about a week Transcription is slow. Perhaps 15:1 ratio. Blitzscribe, LENA, etc. probably will not work Currently available data may not be perfect for a given issue Corpora may need enhancement through MOR or Coder’s editor 9
    10. 10. Tools from the WebData: childes.psy.cmu.edu/dataCLAN: childes.psy.cmu.edu/clanManuals: childes.psy.cmu.edu/manualsMorphosyntax: childes.psy.cmu.edu/morgramsPhon childes.psy.cmu.edu/phonTutorial videos talkbank.org/trainingDigital video: talkbank.org/dvCA Methods: talkbank.org/CABank
    11. 11. Why no handout?“Overviews” link has this PPT presentationCHILDES is now fully electronic. No more paper. 11
    12. 12. Available MethodsMicroanalysis - CA, phonetics, ethologyMicrogenetic analysis - CA, code-switching (NEXT)Group and treatment comparisons - GeneseeError analysis - YipMatthewsDiffusion analysis - in preschoolsLongitudinal studies - growth curvesModeling - neural nets, dynamic systems,evolutionary models
    13. 13. CLAN ToolsTranscribingEditingCounts -- FREQ, KWALAnalyses: MOR, GRASP, PHONInteroperability -- ELAN, Praat, SFS,EXMARaLDA, CLAPI, PHON

    16. 16. Ground RulesEthical use, informed consentLevels of permissionRespect for dignity of participantsRespect for contributorsRequirement to cite sourcesRequirement to contribute data 16

    18. 18. Getting Set UpDownload CLAN from Programs link 18
    19. 19. Windows issuesYou can work in c:childesBut your administrator may have this locked,so, you may need shortcuts.Windows IPA is difficult.Windows compression may produce .wmf 19
    20. 20. Downloading ManualsCHAT, CLAN 20
    21. 21. Sonic ModeEsc-0 to startHighlight areaShift-click to moveedgeHave cursor on linein fileS to insert timemarksTriple click a 36
    22. 22. TranscribingOpen new window (Command-N)Insert headers @Begin @Languages: en @Participants: CHI Target_Child, MOT Mother, FAT Father, ROS Brother @DateF5 with space at each utteranceGo back and transcribe each bullet (c-click)Adjust time marks using Esc-A 37
    23. 23. F5, locate sound, enter bullets 38
    24. 24. Or use SoundWalker 39
    25. 25. Or use the Video Editor 40
    26. 26. ConclusionsCHILDES and TalkBank provide solid toolsfor studying language learning andfunctioningData-sharing has led to major advances inthe fieldNew approaches emphasize the use ofmultimedia analysis, computationallinguistics, and speech technology 58
