Method and system for measuring communication skills of crew members
First Claim
1. A method of measuring crew member communication skills with an audio data processing terminal interfaced with a crew training apparatus, comprising the steps of:
- recording and storing audio data corresponding to a conversation between at least two crew members during a training session-;
extracting respective audio data of each crew member from the stored audio data;
computing a series of measures for at least one prosodic parameter in each respective audio data extracted;
computing a correlation coefficient of the series of measures, wherein the correlation coefficient is indicative of a level of prosodic accommodation between the at least two crew members; and
computing an objective rating of a level of communication skills based on the previous computed metrics, using statistical modelling techniques;
wherein the step of computing the series of measures comprises the further step of periodically sampling the respective audio data in a moving time window, which default length is extended to include the speech utterance of each crew member in its entirety.

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.
