Abstract

The NTSB investigates major transportation accidents in the United States to make recommendations to prevent their recurrence. The Safety Board also examines new technologies that might assist investigations. In conducting its work, the NTSB has found speech analysis a useful new technology for providing secondary evidence on operator state for issues such as psychological stress, alcohol impairment, physical straining, and hypoxia. This talk provides examples from two investigations: the groundingoil spill of the Exxon Valdez tanker and the crash of a Boeing 737 airliner at Pittsburgh.
