Abstract: A training tool, method and a system for measuring crew member communication skills are disclosed, wherein an audio data processing terminal interfaced with a crew training apparatus, typically a crew-operated vehicle simulator. Audio data corresponding to a conversation between at least two crew members is recording during a training session and stored. Respective audio data of each crew member is extracted from the stored audio data, and a series of measures for at least one prosodic parameter in each respective audio data extracted is computed. A correlation coefficient of the series of measures is then computed, wherein the correlation coefficient is indicative of a level of prosodic accommodation between the at least two crew members. Specific communication skills in addition to prosodic accommodation performance can the be determined inferred.
