Minimum effort adaptation of automatic speech recognition system in air traffic management Open
Advancements in Automatic Speech Recognition (ASR) technology is exemplified by ubiquitous voice assistants such as Siri and Alexa. Researchers have been exploring the application of ASR for Air Traffic Management (ATM) systems. Initial pr…
Safety Aspects of Supporting Apron Controllers with Automatic Speech Recognition and Understanding Integrated into an Advanced Surface Movement Guidance and Control System Open
The information air traffic controllers (ATCos) communicate via radio telephony is valuable for digital assistants to provide additional safety. Yet, ATCos have to enter this information manually. Assistant-based speech recognition (ABSR) …
Assistant Based Speech Recognition Support for Air Traffic Controllers in a Multiple Remote Tower Environment Open
Assistant Based Speech Recognition (ABSR) systems for air traffic control radiotelephony communication have shown their potential to reduce air traffic controllers’ (ATCos) workload. Related research activities mainly focused on utterances…
Validating Automatic Speech Recognition and Understanding for Pre-Filling Radar Labels—Increasing Safety While Reducing Air Traffic Controllers’ Workload Open
Automatic speech recognition and understanding (ASRU) for air traffic control (ATC) has been investigated in different ATC environments and applications. The objective of this study was to quantify the effect of ASRU support for air traffi…
Innovative Integration of Severe Weather Forecasts into an Extended Arrival Manager Open
In the H2020 project “Satellite-borne and INsitu Observations to Predict The Initiation of Convection for ATM” (SINOPTICA), an air traffic controller support system was extended to organize approaching traffic even under severe weather con…
Reducing Controller Workload by Automatic Speech Recognition Assisted Radar Label Maintenance Open
Various new hard- and software centered methods were recently implemented to replace paper flight strips through modern technical solutions. These solutions provide valuable information for other ATM applications about the verbally given g…
Building Blocks of Assistant Based Speech Recognition for Air Traffic Management Applications Open
In air traffic control rooms around the world paper flight strips are replaced through different digital solutions. This enables other systems to access the instructed air traffic controller (ATCo) commands and use them for other purposes.…
Semi-supervised Adaptation of Assistant Based Speech Recognition Models for different Approach Areas Open
Air Navigation Service Provider (ANSPs) replace paper flight strips through different digital solutions. The instructed commands from an air traffic controller (ATCOs) are then available in computer readable form. However, those systems re…
Iterative Learning of Speech Recognition Models for Air Traffic Control Open
Automatic Speech Recognition (ASR) has recently proved to be a useful tool to reduce the workload of air traffic controllers leading to significant gains in operational efficiency. Air Traffic Control (ATC) systems in operation rooms aroun…
Machine Learning of Controller Command Prediction Models from Recorded Radar Data and Controller Speech Utterances Open
Recently, the project AcListant® related to automatic speech recognition has achieved command recognition error rates below 1.7% based on Assistant Based Speech Recognition (ABSR). One main issue to transfer ABSR from the laboratory to the…
