SESAR Interview Airspace World - Speech Recognition

Hartmut Helmke of DLR discusses how speech recognition can reduce click time of ATCOs, improve controller worldload and even reduce fuel consumption.

Click time of air traffic controllers (ATCos) reduced from 12,800 seconds down to 405 seconds by using the automatic speech recognition and understanding (ASRU) architecture developed by the SESAR HAAWAII project.

Between the 14 September and 3 November 2022, HAAWAII coordinator DLR, together with 12 controllers from Austro Control, conducted validation trials in support of the PROSA project and its work on attention guidance to quantify the benefits of automatic speech recognition and understanding on controllers workload and flight safety.
