Recorded voice data, such as from CVRs or air traffic control (ATC) tapes, can be an important source of information for accident investigation, as well as for human factors re- search. During accident investigations, the extent of analysis of these recordings depends on the nature and severity of the accident. However, most of the analysis has been based on subjective interpretation rather than the use of systematic methods, particularly when dealing with the analysis of crew interactions.
This paper presents a methodology, called conversation analysis, which involves the de- tailed examination of interaction as it develops moment-to-moment between the participants, in context. Conversation analysis uses highly detailed and revealing transcriptions of recorded voice (or video) data that can allow deeper analyses of how people interact.
The paper uses conversation analysis as a technique to examine CVR data from the Westwind accident.
