| Popis: | This paper describes an initial attempt to develop a protocol for speech analysis techniques that might lead to a better understanding of the cognitive and emotional states that underlie the behavior of people involved in accidents. A tape recording of radio transmissions made by a pilot during both routine and emergency flight conditions was analyzed. Five primary speech measures were made for each statement: mean fundamental frequency (f0), range of fundamental frequencies (Δf0), duration, mean amplitude and syllable count. Speaking rate (syllables per second) and two other derived measures were computed later. During routine flight, the pilot's f0 averaged 123.9 Hz, but this increased to an average of 200.1 Hz during emergency conditions. Range of f0 also increased significantly, while syllable count decreased. These changes may provide a profile of a response to extreme stress that may be useful for gaining insight into situations in which such stress is not otherwise apparent. |
