Special session on Interspeech 2021 conference

ATCO2 project (in association with other related HAAWAII project supported by EC) has succeeded with its proposition to organise a special session at Interspeech 2021 conference (30.8 - 3.9.2021). Interspeech is the lead international conference organised yearly, focused primarily on research and applicability of the technologies on speech/audio. The conference has a high ranking, with acceptance of the accepted papers below 50%.





The organised session is dedicated to automatic speech recognition in air-traffic management, and the following agenda of the session has been released:

Goal of the special session:

Air-traffic management is a dedicated domain where in addition to using the voice signal, other contextual information (i.e. air traffic surveillance data, meteorological data, etc.) plays an important role. Automatic speech recognition is the first challenge in the whole chain. Further processing usually requires transforming the recognized word sequence into the conceptual form, a more important application in ATM. This also means that the usual metrics for evaluating ASR systems (e.g. word error rate) are less important, and other performance criteria (i.e. objective such as command recognition error rate, callsign detection accuracy, overall algorithmic delay, real-time factor, or reduced flight times, or subjective such as decrease of a workload of the users) are employed.


Main objective:

This special session is to bring together ATM players (both academic and industrial) interested in ASR and ASR researchers looking for new challenges. This can accelerate near future R&D plans to enable an integration of speech technologies to the challenging, but highly safety oriented air-traffic management domain.



The organisation is split among two persons (Hartmut Helmke (DLR, coordinator of HAAWAII project) and Pavel Kolcarek (Honeywell, topic manager of ATCO2 project).
