- 1. Introduction to CHILDESand TalkBank Brian MacWhinney CMU - Psychology, Modern Languages, Language Technologies Institute
- 2. The goal ofTalkBank
- 3. The core idea Humancommunication is a single unified process. However, patterns in communication are analyzed by 20 different fields. The time scales of the processes varies from milliseconds to centuries. But all of these processes must have their ultimate effect in the Moment. We can capture the Moment on video.
- 4. Principles Data-sharing, Informed Consent Multimedia OpenAccess, Web Access, Commentary Specified Format Interoperability Community integration
- 5. Availability http://childes.psy.cmu.edu http://talkbank.org programs, manuals, fonts,morphologies, CA conventions, video production guides, XML Schema, links to other programs data can be either downloaded or played back over the web

- 9. Practical Considerations LearningCLAN 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. Tools from theWeb Data: childes.psy.cmu.edu/data CLAN: childes.psy.cmu.edu/clan Manuals: childes.psy.cmu.edu/manuals Morphosyntax: childes.psy.cmu.edu/morgrams Phon childes.psy.cmu.edu/phon Tutorial videos talkbank.org/training Digital video: talkbank.org/dv CA Methods: talkbank.org/CABank
- 11. Why no handout? “Overviews”link has this PPT presentation CHILDES is now fully electronic. No more paper. 11
- 12. Available Methods Microanalysis -CA, phonetics, ethology Microgenetic analysis - CA, code-switching (NEXT) Group and treatment comparisons - Genesee Error analysis - YipMatthews Diffusion analysis - in preschools Longitudinal studies - growth curves Modeling - neural nets, dynamic systems, evolutionary models
- 13. CLAN Tools Transcribing Editing Counts --FREQ, KWAL Analyses: MOR, GRASP, PHON Interoperability -- ELAN, Praat, SFS, EXMARaLDA, CLAPI, PHON

- 26. Conclusions CHILDES and TalkBankprovide solid tools for studying language learning and functioning Data-sharing has led to major advances in the field New approaches emphasize the use of multimedia analysis, computational linguistics, and speech technology 58
