Voice Initiated Cockpit Control and Interrogation (VICCI) System Test for Environmental Factors.
Abstract
The objectives of the contract were to investigate the effects of the pilot's acoustic environment, optimize system parameters for operation in the cockpit environment, provide system performance statistics, and investigate the availability of on-board computing systems which may be utilized. Voice data were recorded in aircraft cockpits and in an altitude test chamber. These data were analyzed to determine the effects of the environment and of physiological stresses experienced by the speakers. The results of the analyses determined modifications to be made to a simulated voice control system. The recorded data were then processed by the simulated system to obtain performance statistics. Lack of positive control over environmental variables and the inability to provide an immediate indication of system response to the speaker resulted in a data base inadequate to support statistically significant results. However it was noted that the main sources of interference to reliable speech recognition in the cockpit environment are sounds made by the pilot's oxygen supply equipment and his own breathing sounds. Methods for accommodating such sources ar suggested. (Author)
