AcListant® Initial Briefing for Participants of Automatic Speech Recognition Trials at DLR in January 2017

Abstract

The Helmholtz Validation funded project “AcListant®” (Active Listening Assistant) focused on the integration of an assistance system (Arrival Manager, AMAN) with Automatic Speech Recognition (ASR). The AcListant® stakeholders have suggested extending the AcListant project to the field of electronic flight labels, since a shorter-term introduction to market is expected.The validation of the AcListant® prototype did not encompass the integration of electronic flight labels and speech recognition to reduce the workload of air traffic controllers, in the first place. The results of the validation revealed very positive qualitative statements of the observers and air traffic controllers. However, decision-makers prefer at this point quantitative statements. As Within this validation project the quantification of the benefits – particularly the reduction of air traffic controller workload – by means of speech recognition based assistance as an input modality for electronic flight labels will be investigated. Integration of electronic flight labels with Automatic Speech Recognition was validated in November and December 2015 with controllers from DFS and Austro Control.1 These validation trials are repeated in January 2017 with controllers from LFV, Naviair, Croatia Control and Irish Aviation Authority. It is planned to repeat the trials exactly in the same way then in 2015 in order to reduce adaptation effort and not to risk quality. Maybe the duration of each trial may be reduced from 60 minutes to 45 minutes. The 3 trials from December 2015 lasting 45 minutes each should not be reduced in duration. 2.2
