CLAN (supports Jeffersonian notation)...the most general tool available for transcription, coding, and analysis.
Phon ...phonological and phonetic data analysis ...transcribed in CHAT. Fully compatible and interoperable with CLAN.
ELAN ...analysis of gesture (from video) and conversational overlap. Complete interoperability between ELAN and CLAN.
EXMARaLDA ... "Extensible Markup Language for Discourse Annotation"....XML for DA? Think of this linked up with A/V. Very powerful concept...but how's the praxis?
Also looking at retail options as well...any advice / personal experiences welcome:
