The Recording and Preliminary Analysis of a Data Base for the Assessment of 'Strain' in Air Traffic Controllers, Using Speech

摘要

A data base of Air Traffic Controllers' verbal communications during periods of high and low activity was tape recorded during the Farnborough International Airshow in 1978. A description of the data base is given together with the activity measures used. The data base was obtained to provide a means of testing the hypothesis that the speech signal can be used to assess 'strain' or the effects of increasing 'stress' in work. Preliminary statistical analysis of the voice 'pitch' of one of the controllers has shown that periods of high and low activity may be readily discriminated using several 20 second segments of voiced speech.
